铁边城—吴岔南井区注水开发技术研究

Research on Water Injection Development Technology of Tiebian Cheng-Wucha South Well Area

吴岔南井区是铁边城油区重要产油区之一,自上而下钻遇了延安组、延长组等多层系含油复合区,主力生产层系为长4+5。截至2022年5月底,区块总井数180口,其中采油井135口,注水井45口。文章中的研究通过地质和试油试采数据,以完善注采井网及注采对应为目标,实施科学配注,实现该区高效注水开发。

The Wucha South well area is one of the important oil-producing areas in Tiebian Cheng oilfield.The multi-layer oilbearing complex areas such as Yan’an formation and Yanchang formation were drilled from top to bottom.The main production layer is Chang 4+5.By the end of May 2022,the total number of wells in the block is 180,including 135 production wells and 45 injection wells.Based on the geological data and oil test and production data,this study aims to improve the injection and production well pattern and corresponding injection and production,implement scientific injection distribution,and realize efficient water injection development in this area.
