Intervals of kerogen-siliceous-carbonate rocks enriched in organic matter have been established, which, according to a complex of microand macrocharacteristics, can be attributed to domanikoid-type sediments. The Domanikoid highcarbon formation of the neighboring Volga-Ural Basin is an effective source rock. The generative potential of the established domanikoid-type sediments of the Koblandy-3 well is characterized by high TOC values of 0.1-5.7%, the Production Index (PI) varies from 0.1-0.3, which corresponds to the oil window.

A comprehensive research method was used, including a review and synthesis of scientific and patent publications, analytical studies of methods for creating backwash during well drilling. Their advantages and disadvantages are revealed. The greatest attention is paid to drilling of large-diameter wells with backwash, which is widespread in foreign countries in the development of groundwater reserves. The presented materials showed a clear advantage of this method over others, both in terms of the quantity and quality of produced water, and in terms of well operation. It is shown that, under local conditions, the advantages of this method can have a particularly pronounced effect, and its disadvantages will manifest themselves to a minimal extent. The advantages of rotary backflushing over other drilling methods can be considered proven. It will provide a sharp increase in the utilization rate of local groundwater resources, which is the main problem of local groundwater supply. The need for widespread implementation of this method is obvious. The influence of the upward flow rate of the drilling fluid and its density on the maximum depth of drilling with backwash using an airlift has been studied. An improved device of the circulation system for drilling wells with backwash using an airlift has been developed. Thanks to its use, it becomes possible to use commercially available drill pipes with conventional connections. This allows you to increase the drilling speed by reducing the time spent on tripping operations.","PeriodicalId":272594,"journal":{"name":"Neft i gaz","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117129021","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 maximum amount of aromatic hydrocarbons (43.6%) in the processing of the propane-butane fraction is formed on the Zn-La-P-ZSM-Al2 O3 catalyst at 500 °C, while the selectivity for aromatic hydrocarbons is 80.0%. When processing the propane- propylene fraction in the temperature range of 400-600°C, the yield of aromatic hydrocarbons on the Zn-La-P-ZSM-Al2O3 catalyst is significantly higher compared to other studied catalysts. The activity of catalysts in the processing of light hydrocarbons mainly depends on the structure and state of active centers and the conditions of the process. The results of the study of catalysts by electron microscopy and thermal desorption of ammonia showed that acid sites coexist with metal sites on the surface of the developed catalysts. The composition of acid sites can include metals in various degrees of oxidation, fixed both inside the zeolite cavities and on their outer side. The most active, stable KTG-4 catalyst (Zn-La-P-ZSM-Al2 O3 ) is recommended for pilot testing at gas and oil refineries when processing propane-butane fraction and gases released during catalytic cracking into aromatic hydrocarbons.","PeriodicalId":272594,"journal":{"name":"Neft i gaz","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117159482","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}

It is important to take into account the energy resources that increase with depth. Following this concept, based on the tasks of geological exploration, a downhole layout has been developed and introduced into the production of drilling wells, with design features and technological capabilities focused on a comprehensive solution to the problems of well wiring. Structurally, the downhole layout aimed at maximizing the potential energy of the working fluid is universal, designed for drilling wells with core sampling of increased diameter (100 mm or more), and with a solid face. In addition to the outer pipe and core receiver, the downhole layout is equipped with diamond drill heads with a stepped matrix, with a separate system of flushing channels, collectively realizing the effect of hydro-mechanical destruction of rocks. By introducing into the composition of the bottom-hole layout, converting the ascending flow into a rotational-ascending one, the problem of removing sludge from under the end of the stepped matrix is effectively solved. Production tests of the downhole layout with core sampling were carried out at the polymetals deposit of Central Kazakhstan, solid face during drilling of groundwater wells in the territory of the Almaty region. According to the results of production tests, it was found that the hydro-mechanical destruction of rocks is especially effective in combination with diamond drill heads with a stepped matrix. The presence of a turbulator-expander in the bottom-hole layout made it possible to significantly increase the amount of incoming sludge of drilled rock in the well sump, especially when drilling wells with a solid face. In comparable geological and technical conditions of drilling wells, serial core sets HQ with a drilling diameter of 95.6 mm had the following indicators: energy consumption – 2.1-2.4 kW / hour, core yield with a diameter of 63 mm – 93%, specific lumpiness of the core – 5-8 pcs / per linear meter of drilling, drilling was carried out at an axial load of 2200-2500 kgf, rotation speed 500-700 rpm.
