自2005年以来油水井大面积套变,严重影响了区块的开发效果,开发矛盾极其突出,导致区块较高含水条件下采出程度偏低。本文针对此问题从提高井网适应性等方面入手进行了论述,立足于调整完善注采井网、理顺注采关系,提高分层有效注水,实现区块良性开发。
Since 2005, oil and water wells have been extensively altered in a large area, which has seriously affected the development effect of the block. The contradiction between development is extremely prominent, resulting in a low level of recovery in the higher water-bearing area of the block. In this paper, this article addresses the issue of improving well network adaptability and other aspects, based on the adjustment and improvement of injection well pattern, rationalize the relationship between injection and production, improve the effective stratified water injection, to achieve benign development of the block.
