These measures include hydraulic fracturing, multi-stage hydraulic fracturing, matrix acid treatment, acid fracturing, etc. These processing methods allow existing wells to support hydrocarbon production without drilling new wells. During these treatments, certain specialized particles or technical devices are used for isolating an already existing perforation or for liquid flow diverting. These particles or devices are usually called flow diverters, which can prevent the use of a drilling rig to create temporary physical barriers, reducing the overhaul cost. Recent improvements in flow deflection technology allow the use of various decomposable particles that act as a temporary bridge either at the perforation entrance or inside an existing crack. The basic principles of the injected compounds flow deflection are to create filtration resistance to the advance of the acid composition in the highly permeable part of the collector and the coating of untreated cracks.

In addition, there is a tendency to use liquefied gas to replace liquid hydrocarbon fuels (gasoline, kerosene, gasoil, fuel oil). Due to the growth and emergence of new industries for liquefied natural gas consumption, the infrastructure necessary for its production, transportation and storage is being developed.  \u0000The article presents an analysis of the use of the most common polymers for the pipeline construction in the oil and gas industry. The possibility of using ultra-high molecular weight polyethylene for the construction of process lines for pumping cryogenic liquids was considered. The results of experimental studies on tensile strength test and Charpy impact strength test after exposure to liquid nitrogen are presented. As a result of tensile strength tests, an increase in the strength properties of the material was observed while maintaining its plasticity. The breaking stress was 37.7 MPa, the yield strength was 27.1 MPa at liquid nitrogen temperature, while at ambient temperature, the specimen failed at 26.9 MPa, the yield strength was 20.2 MPa. The specimens, tested for impact strength by the Charpy method, after exposure for 2 h in liquid nitrogen, a certain margin of plastic properties was also showed. The stress-strain state of a liquefied natural gas pipeline made of ultra-high molecular weight polyethylene in an insulating coating was simulated using the ANSYS Mechanical software package, taking into account its thermal interaction with the soil. The maximum equivalent stress in the model was 14.4 MPa, with calculated value of 12.7 MPa, which does not exceed the yield point of the material. Thus, ultra-high molecular weight polyethylene can be considered as a promising material for use at cryogenic temperatures.","PeriodicalId":42555,"journal":{"name":"Nauka i Tehnologii Truboprovodnogo Transporta Nefti i Nefteproduktov-Science & Technologies-Oil and Oil Products Pipeline Transportation","volume":"11 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83669702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most significant effect of loads is manifested at pipeline crossings across rivers. The stability of underwater pipeline design position and thus its reliability is achieved by ballasting with the required intensity. The current regulatory document SP 36.13330.2012 provides for the required intensity determination, taking into account the water buoyancy force and pipeline crossing along the longitudinal profile of the transition. At the same time, it should be noted that ensuring pipeline bending along the longitudinal profile of the crossing with the use of ballasting of the required intensity also depends on the internal forces acting in the pipeline wall during operation. However, this document does not take into account operational loads when determining the required ballasting intensity. In addition, ballasting with the ensuring pipeline bending along the longitudinal profile of the crossing leads to the occurrence of bending stresses, in some cases quite high, which affect the level of total stresses, strength and reliability of the structure. In many cases, water occupies only part of the concave section of the pipeline at crossings. Taking into account the above conditions and features, studies of the ballasting of underwater crossings of trunk oil and gas pipelines were carried out. \u0000The aim of the work is to obtain analytical dependences of the ballasting intensity and bending stress in an underwater pipeline at different altitude water levels at the transition from operational loads and geometric characteristics of the crossing. \u0000The research method is a theoretical study of the stress-strain state of an underwater pipeline under the action of operational loads and weights. \u0000The dependences of ballasting intensity with weights of the underwater pipeline on the operational loads and the geometric characteristics of the transition at different elevations of the water level at the transition are obtained, and the highest bending stresses in the pipeline wall at the underwater crossing are determined.

The study summarizes results of researches in drilling wastewater treatment methods. It is relevant for areas of extraction of hydrocarbon raw materials.

Soil, ash, starch, peat and coal were cleaned from impurities and ground to a fine state. Eleven individual materials and their various combinations were studied as filter loads. The tests were replicated three times. Untreated drilling wastewater served as a control background sample for calculating efficiency. The possibility of wastewater treatment by sedimentation and subsequent filtration using industrial waste as a loading material for filter was researched.

Most of the existing methods used to assess depreciation are narrowly focused and expensive, for example, flaw detection of downhole equipment, tubing, rod and pumping equipment, which can eventually reach the cost of the equipment itself. To date, one of the main methods for assessing the equipment state is the analysis of its operation time, which directly depends on the identification accuracy. Various technological solutions are used as an identifier, for example, barcodes, seals with technical information, however, such controls are unreliable, wear out quickly, and, as a result, it becomes difficult to correctly identify them. \u0000The paper considers the technology of radio frequency identification (RFID) – «RFID-tags», describes the operation principle and its features.

Их применение позволяет обеспечить сокращение объемных потерь перекачиваемой среды из напорной области во всасывающую через зазор между ротором и статором – перетечек, которые являются одним из факторов снижения объемного КПД насоса при эксплуатации. В качестве щелевых уплотнений для магистральных насосов типа НМ наиболее распространены плоскощелевые и плоскощелевые ступенчатые уплотнения. Однако при их использовании величина объемных потерь остается ощутимой (для насосов большой мощности – до 1 % в полном КПД насоса), что требует соответствующих технических решений. Целью настоящей работы является совершенствование узла щелевого уплотнения для сокращения перетечек и, соответственно, повышения энергоэффективности магистрального насоса. Авторами проведено исследование с оценкой технической целесообразности применения сотовых уплотнений в узлах щелевых уплотнений роторов магистральных насосов. По результатам компьютерного моделирования течения в проточных частях зазоров установлено, что сотовые уплотнения обеспечивают снижение объемных потерь расхода в проточной части магистрального насоса и превышают характеристики применяемых в настоящее время плоских щелевых уплотнений.

Their use allows for the reduction of volumetric losses of the pumped medium from the discharge area to the suction area via the clearance between the rotor and stator - overflows, which are one of the factors reducing the volumetric efficiency of the pump during operation. The most commonly used groove seals for NM mainline pumps are the flat-groove and flat-groove stepped seals. However, when they are used, the value of volumetric losses remains tangible (for high-capacity pumps – up to 1 % of overall pump efficiency), which requires appropriate technical solutions. The purpose of this work is to improve the groove seal assembly in order to reduce overflows and, as a result, improve the energy efficiency of the mainline pump. The authors conducted a study to assess the technical feasibility of using honeycomb seals in groove seal assemblies of mainline pump rotors. According to the results of computer simulation of the flow in the flow paths of clearance, honeycomb seals reduce volumetric flow losses in the flow path of the mainline pump and outperform the characteristics of the currently used flat groove seals. We have developed requirements for honeycomb seals of impellers, taking into account the operating parameters of NM mainline pumps.","PeriodicalId":42555,"journal":{"name":"Nauka i Tehnologii Truboprovodnogo Transporta Nefti i Nefteproduktov-Science & Technologies-Oil and Oil Products Pipeline Transportation","volume":"292 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79398524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Для ремонта таких участков предлагается использовать разрезные тройники, которые монтируются на трубопровод сварными угловыми швами без остановки перекачки продукта. Контролировать качество таких швов трудно, при этом в случае возникновения дефекта их ремонт сваркой нежелателен, так как повторное наложение термического цикла сварки вызовет в металле структурные изменения, рост сварочных напряжений и деформаций, что в совокупности приведет к снижению несущей способности стенки трубопровода. Проведен отбор разрезных тройников по критериям прочности, герметичности и объему сварочных работ при монтаже. Для снижения остаточных сварочных напряжений в корневой части монтажных швов предложено увеличить длину тройника по магистрали, что, по расчетам, позволяет уменьшить напряжения в сварных соединениях разрезного тройника и увеличить ресурс ремонтного узла при циклическом нагружении почти на 20 %.

To repair such sections, it is proposed to use split tees, which are mounted on the pipeline with welded corner joints without stopping the pumping of the product. It is difficult to control the quality of such welds, and in the event of a defect, their repair by welding is undesirable, because reapplying the welding thermal cycle causes structural changes in the metal, as well as the growth of welding stresses and strains, all of which contribute to a decrease in the bearing capacity of the pipeline wall. The split tees were selected based on their strength, tightness, and the amount of welding work required during installation. It is proposed to increase the length of a split tee along the mainline to reduce residual welding stresses in the root part of the mounting seams, which, according to calculations, allows to reduce stresses in the welded joints of the split tee and increase the resource of the repair assembly by almost 20 % under cyclic loading.

The prerequisites for the emergence of this technology are given, and the first experimental studies in this area on operating pipelines in Russia and the USA are described. The contradictory results of the experiments on quantification of the mixture formed during the diverse oil products batching by direct contact are shown. It is indicated that the ambiguous practical data did not allow to reliably estimate and predict the batch volume and its extent. To solve these problems in the prevailing conditions, a theoretical justification of the mixture formation process at the two-medium contact boundary was necessary. The development of the theory of batching is shown: from the simplified model of mechanical mixing of liquids, proposed in 1938 by V. S. Yablonsky, to the fundamental diffusion theory of mixing, formulated in 1954 by Taylor, which became the basis for further research. It is noted that the active introduction of batching into production began in the late 1940s.
