安塞油田黑山梁区长6油层组单砂体构型分析及平面展布特征OA北大核心CSTPCD
Configuration analysis and plane distribution characteristics of single sand body in Chang 6 reservoir formation of Heishanliang area,Ansai oilfield
安塞油田黑山梁区块位于延安市安塞区,三叠系延长组长6油层组是其主力产油层.目前该区已进入注水开发阶段,但砂体展布、非均质性、砂体叠置规律等认识不清,导致开发过程中存在注水受效程度不均衡,整体水驱效果差等问题.为此,本次研究依托丰富的测井、录井资料,以及岩心、镜下薄片资料和分析测试数据,开展地层精细刻画、沉积微相、砂体平面分布及单砂体叠置规律的综合研究.结果表明:黑山梁地区长6时期主要发育三角洲前缘亚相,岩性以细粒长石砂岩为主,分选性中等—好,磨圆…查看全部>>
Heishanliang block of Ansai oilfield is located in Ansai area,Yan'an City.The Triassic Yanchang Chang 6 oil formation is its main oil producing layer.At present,the area has entered the stage of water injection development,but there is a lack of clear understanding of the distribution,heterogeneity and stacking patterns of sand bodies,leading to problems such as imbalanced water injection efficiency and overall poor water drive effect during the development …查看全部>>
