马厂油田开发后期部署高效井的关键技术
|
摘要
开展了以地层精细对比和三维地震多参数解释为技术核心的多学科综合研究工作 ,对马厂油田的构造、油藏规律进行深入研究 ,认为马厂油田是典型的复杂断块油田 ,具有含油气井段长 ,油气藏数量多 ,含油高度低 ,规模一般较小 ,油气分布广泛 ,各断块自成为独立的油水系统的油气分布特点。西倾的马厂系列断层与东倾地层形成的反向屋脊断块 ,是良好的含油气圈闭 ,在断块高部位部署大斜度双靶定向井可实现油藏的高效开发。沙三下 4- 7砂组及沙四段动用程度低 ,潜力较大 ,是滚动增储的主攻方向。
To get progressive reserves,allocate high efficiently progressive development wells,and search for new successive developing units,the various comnprehensive research have been made which focus on fine strata correlation and 3 D seismic multi parameter interpretation in Machang Oilfield,which study its structure and reservoir principle It can be concluded from which that the Machang Oilfield is a complicated fault block oilfield with characteristics of long oil bearing section,multiple reservoirs,low oil bearing height,generally small scale,wide spread hydrocarbon distribution and independent oil water system in every block West inclinded Machang fault series forming antithetic roof tree faults with east inclined formation,which is a favorable hydrocarbon bearing trap and can be devleloped efficiently with high inclination double target center directional well at high localization of fault block Es 3 4 7 and Es 4 sections are the main targts of progressive reserves for their low producing degree and large potential
