This paper addresses the issue of erosion corrosion of oil pipelines in oil fields under the action of multiphase flow, the main factors affecting the erosion corrosion are introduced, including the hydrodynamic factors, solid particle properties, fluid medium properties and temperature, It summarizes and analyzes the mechanisms through which these different factors affect the erosion corrosion of oil pipelines. The paper points out that increased fluid velocity in oil pipelines, sudden changes in flow patterns, and turbulent kinetic energy can accelerate erosion corrosion to some extent, With the increase of flow rate, erosion corrosion mechanism will change from electrochemical corrosion dominant to erosion accelerated corrosion, There is a maximum value for erosion corrosion based on the solid particle impact angle. The harder and sharper the solid particles are, the stronger their impact on the pipeline, especially the impact of low Angle impact is more significant; however, the diameter and quantity of particles can affect the development of erosion corrosion due to 'particle size effect' and 'shielding effect.' Additionally, lower pH values and higher temperatures of the fluid medium will increase pipeline erosion corrosion. Finally, future research directions for studying erosion corrosion in oilfield pipelines under multiphase flow conditions are discussed in light of existing research.\"\u0000","PeriodicalId":21652,"journal":{"name":"Science Discovery","volume":"45 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141813447","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}

Due to the complex sedimentary environment, the sand body shows great variation in thickness and distribution. In this study, the method of combining well vibration, model forward modeling and stratum slicing are used to predict the sandstone bodies of different thickness successfully. Especially for the thin sand body with a thickness of less than 5 meters, this study found that the GR curve can effectively distinguish sandstone and mudstone through the intersection analysis of logging curves, and applied the GR curve co-simulation inversion technology to perform fine characterization. In addition, the study also reveals that the northeastward twisting fault zone in Xinmin area is a favorable accumulation area of the reservoir, which provides a new direction for oil and gas exploration. This study not only improves the accuracy of sandstone prediction, but also provides a valuable reference for oil and gas exploration under similar complex geological conditions.\u0000","PeriodicalId":21652,"journal":{"name":"Science Discovery","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679807","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}
