According to the biomarker study, it was revealed that the oils of central and western Nuraly have genetically different origins, and the petroleum accumulation in the southern part of West Nuraly was formed by the continuous secondary migration of HC from the northeastern and northwestern directions. Oils from central Nuraly field have higher thermal maturity and lower density than those of western Nuraly do. The thermal maturity of samples from Central Nuraly decreases from the northeastern part of Nuraly towards the southwestern part, which may also attest to hydrocarbon migration pathways. The presence of gas caps in the northeastern part of Central Nuraly may be due to their high thermal maturity.","PeriodicalId":17771,"journal":{"name":"Kazakhstan journal for oil & gas industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73251281","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 size of the fraction in the used solid powder does not exceed 40 microns in diameter. The demulsifier consists mainly of hematite (Fe2O3) and corundum (Al2O3) phases. The introduction of fly ash into the oil emulsion leads to demulsification of water from oil. The dosage of the powder ranged from 0.1 to 1 g. An increase in the dosage of fly ash leads to a rapid discharge of water from the emulsion. The study identifies the demulsifying properties of fly ash powder. Also, upon redispersion of demulsified samples, no re-emulsion was observed, as a result of which, it can be assumed that fly ash powder can contribute to deasphalting of oil-water emulsion. Reuse of industrial waste is an important method for improving the ecological state of the country.","PeriodicalId":17771,"journal":{"name":"Kazakhstan journal for oil & gas industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82054654","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}

In injection wells, under the action of water injected into the reservoir, intensive leaching of the cement stone occurs, which leads to its complete degradation after several years of well operation. The consequence of this is the injection of fluid into other formations and increased corrosion of the casings. Analysis of the field experience of injection wells showed that inter-reservoir crossflows result in cement stone complete collapse in 4-6 years, while in production wells it retained its properties after 20 years. \u0000Theoretical consideration of the leaching corrosion process made it possible to determine the main directions of reducing the corrosion rate, aimed at improving the structural characteristics of cement stone. Among these, a decrease in the initial water-content and optimization of the porous structure should be optimized. \u0000Analysis of the loads acting on the cement sheath in wells showed that during perforation, hydraulic fracturing and well drilling for deepening, the stresses arising in the cement stone exceed its strength characteristics. Therefore, it is advisable to use reinforced and self-healing cements to minimize these negative effects.","PeriodicalId":17771,"journal":{"name":"Kazakhstan journal for oil & gas industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86338355","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}
