In deepwater drilling operation, the rise in temperature of the closed casing annulus is easy to produce the phenomenon of rising annulus pressure, and due to the special characteristics of the underwater wellhead device, it is not possible to release the annulus pressure between the casing, and the high annulus pressure will lead to casing extrusion and deformation, which will seriously threaten the safety and integrity of the wellbore. In order to ensure the smooth progress of deepwater drilling operations and reduce operational risks, corresponding methods and strategies are proposed for the management of annulus pressure in deepwater oil and gas wells. A variety of measures and products have been developed worldwide for engineering measures of annulus pressure management, including optimization of well structure and cementing design, use of rupture discs, foam casing and vacuum tubing, and other measures. This paper analyzes five major categories of prevention methods and control techniques for deepwater oil and gas wells well annulus confinement pressure, which are increasing casing strength (stiffness level, wall thickness), eliminating expanding fluid, blocking heat transfer, balancing fluid thermal expansion and releasing annulus confinement pressure management strategies. Measures to control annulus pressure by increasing casing strength (stiffness level, wall thickness), fully sealing the annulus, vacuum insulated tubing, foam casing, nitrogen foam isolation fluid, non-circumferential pipe shoes and rupture disc casing tools and analyzing their engineering advantages and disadvantages. According to the engineering application experience, the use of rupture disk casing tool to alleviate the annular pressure is currently the most widely used and stable and reliable means in the world. And according to the theoretical knowledge and engineering practice of annular pressure management, the basic strategy of annular pressure management is summarized when rupture disk is adopted as the main means of annular pressure management.</p>","PeriodicalId":9908,"journal":{"name":"Chemistry and Technology of Fuels and Oils","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data quality and integrity have become key issues in both research and production. This study analyzes the architecture of data quality control methods based on the technical system of the OSDU (Open Subsurface Data Universe) sharing center. A virtual data layer (VDB) is introduced, and the overall architecture of the exploration and development data exchange management platform is constructed through collaborative technology. Employing a systematic design concept, all applications within the data exchange management architecture are organically combined, forming an integrated and cohesive design and development strategy. This research presents a novel approach where the system application is distinctly separated from the database management. This strategy effectively resolves the challenges associated with managing metadata in oilfield exploration. By designing the database and coding specifications, the development and deployment of the system are completed efficiently. The implemented system offers comprehensive functionalities to all oilfield levels, including data storage, auditing, querying, statistical analysis, and data exchange management. It facilitates the seamless exchange of diverse exploration and development data, ensuring scientific data management and establishing a foundation for shared scientific data. This enhances service quality and the level of exploration and development in the field.

The coal additive consisted of an amorphous carbon phase forming a developed microporous structure. An analysis using scanning electron microscopy and adsorption porometry established that a vapor- air modification of the coal additive changes its surface relief and leads to the development of a micro- and mesopore structure. The intrapore space of the modified coal additive contains 38.6 vol % mesopores with a specific surface area of 172 m²/g. The final products of extra-heavy oil cracking with the proposed coal additive are characterized by an increase in the content of saturated and aromatic hydrocarbons, as well as by an almost complete absence of asphaltenes. The largest hydrocarbon yield was observed during extra-heavy oil cracking in a nitrogen atmosphere. In experiments, asphaltene conversion processes are observed due to the destruction of C–C, C–N, and C–O bonds with the formation of low-boiling compounds and high-carbon substances. The largest yield of aromatic hydrocarbons is observed during cracking in a subcritical aqueous fluid, with the yield of liquid products being reduced due to intensive gas formation.

The differences in reservoir characteristics in different regions make it difficult to scale up the promotion of water injection development parameters. A more effective way is to establish efficient water injection development methods and strategies suitable for the region. Therefore, based on the geological characteristics of the Wucangbao Chang 6 and Chang 9 oil reservoirs, the feasibility of water injection development in Wucangbao reservoir is analyzed from several aspects such as interstitial material content, reservoir hydrophilicity, and stress sensitivity. The water injection parameters of Wucangbao Chang 6 and Chang 9 single wells are calculated using methods such as apparent flow rate method, permeability and single well productivity regression method, and stratigraphic series curve regression method, respectively. The water injection parameters are obtained based on the single well production. The results show that the Wucangbao Chang 6 and Chang 9 reservoirs have good water injection feasibility and prospects in terms of sandstone cement, reservoir fluid properties, wettability, and water flooding efficiency; And the production of single well Chang 6 is 1.5-4.0 t/d, while the production of single well Chang 9 is 2.0-4.5 t/d; According to the injection production balance, the initial single well injection volume of the Wucangbao Chang 6 layer is 10 m³, and the initial single well injection volume of the Chang 9 layer is 20 m³, in order to maximize the recovery rate of the reservoir during the dry or low water cut period.</p>","PeriodicalId":9908,"journal":{"name":"Chemistry and Technology of Fuels and Oils","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the collection and analysis of core samples, this study systematically investigated the types, structural characteristics and pore-permeability relationships of the reservoir sandstones by using rock cast thin section analysis, pore structure delineation test by piezomercury method and experimental analysis by scanning electron microscopy. The results show that the sandstones in the reservoir of the Sangonghe Formation are dominated by feldspathic feldspathic sandstones and clastic feldspathic sandstones, and the maturity of the compositions is on the low side. The analysis of the rounding degree and cementation degree of the reservoir particles reveals its non-homogeneous characteristics, and the porosity and permeability show obvious positive correlation. Characterization of the pore structure of the reservoir shows that the size and distribution of the pore throat radius significantly affects the permeability, and the change of the throat has a more significant effect on the permeability. The porosity of the upper reservoir in the second section of the Sangonghe Formation ranges from 10.9% to 26.1%, with an average value of 17.6%, and the permeability ranges from 0.13 mD to 159 mD, with an average value of 24.43 mD.
