According to the research results, it was concluded that almost on the entire territory of the Astra-khan-Kalmyk Pre-Caspian area there accumulated the sea deposits, predominantly clay deposits. There has been carried out correlation of the inter-well space, as well as interpretation of GIS in the well logs for structural wells drilled on the territory of the Kirikilinsky area in the 1960-1970s. A lithological-facial model was built based on the research results, together with seismic data. The model demonstrates that previous works should be revised, since the territory in the Apsheron period experienced several transgression-regression cycles. As a result of these processes, sandstone beds with alluvial and deltaic facies were formed. The increased sand content of the Apsheron period also proves that the study area is more complex in structure than it was previously thought.","PeriodicalId":237767,"journal":{"name":"Oil and gas technologies and environmental safety","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121815435","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}

Ultrasonic technologies minimize the percentage of water in the extracted oil. The main advantages of the ultrasonic treatment over numerous methods of improving the structural and mechanical properties of heavy metals are its low energy consumption, high efficiency, technical and environmental safety. There have been carried out microscopic studies of the influence of ultrasonic treatment on the disperse phase structure and on the stability of emulsions based on light oil from the Yu. Korchagin field with a mass oil content of 40, 60, 80%. The emulsion stability is shown to become less at the increasing water content in the emulsion. Ultrasonic treatment of stable oil emulsions with 60% of oil content from the Yu. Korchagin field had a significant effect on the emulsion. Both positive (acceleration of stratification) and negative effects (strong heating and evaporation of light oil fractions) were observed. The effectiveness of using ultrasound to intensify the separation of emulsions of the specified composition is confirmed by microscopic analysis of optical images of the emulsion structure, because a significant decrease in the size of water droplets in the layer of the dispersion medium is observed in the course of wave processing.","PeriodicalId":237767,"journal":{"name":"Oil and gas technologies and environmental safety","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124583316","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}
