靖安油田塞248区注水开发效果分析

The Effect of Waterflood Development of SAI 248 Reservoir of JINGAN Oilfield

塞248区为靖安油田侏罗系油藏的一个小油藏,其开采层位为延9层。2004年投入开发,该区在先采后注的开发方式下,经历了产量递减阶段和上升阶段,目前达到平稳阶段,开发呈现良好趋势。该区油井见效初期表现为"三升一降",注水取得了很好的开发效果。本文就该油藏特征及投入开发以来油井见效特征予以分析总结,为下步同类油藏的开发打下基础。

SAI248 Reservoir is a small reservoir of JINGAN Jurassic Oilfield. Production formation of this reservoir is YANg. The year of placing on production was 2004. This reservoir get to development through natural energy development and waterflood development. It has a abundant experience of production decline region and ascend region. Now it goes into a equation region and display a good tendency of development. Response producers of this reservoir display a distinction of ＂Three ascend and one descent＂. Waterflood develbpment of this reservoir get a good effect. This article summarized the distinction of reservoir and the distinction of response producers since the reservoir placing on production. The success development of this reservoir display a compact base for other fellow resevoirs.
