本文针对刘渠区块目前注水开发过程中存在的产量递减快、稳产形势严峻,注水区部分油井水串、水淹现象严重、大部分井长期不受效或受效不明显等问题,从现有井网条件下调整着手,开展了刘渠区块的稳产技术对策研究,提出了老井重复压裂减小注采井距,微裂缝不发育位置处水淹井的深部堵水压裂,初产高、微裂缝发育区水淹井深部堵水等技术措施,取得了较好的改造效果,对该区块后期的稳产提供了有效思路。
In this paper, Liuqu block current output of water development in the process of production decline faster, steady production situation is grim, part of the injection well water string, flooding serious phenomenon, most of the long-term ineffective or ineffective is not obvious and other issues from Under the conditions of well network, we started with the measures to stabilize production and technology of Liuqu block, put forward that the old well repeated fracturing can reduce the deep water plugging and fracturing of water flooding wells where injection well spacing and microcracks are not developed, High production rate and deep water plugging in the micro-fractured development zone, and achieved good transformation effects and provided effective ideas for the stable production in the latter part of the block.
