摘要
在研究了埕北油田储层伤害机理和分析目前各种储层保护措施存在缺陷的基础上,针对埕北油田储层物性,开发了新型储层保护洗井助排工作液,以预防储层伤害。埕北油田现场应用表明,在修井过程中使用洗井助排液作为储层保护措施可有效降低入井液对储层的伤害,并对近井带的堵塞有一定的解除作用,作业后含水恢复期缩短,产液指数上升,储层保护效果显著。该新型洗井助排液的实用性与高效性,为海上油田油井的稳产增产提供了新的思路。
Based on the research of Chengbei oilfield reservoir damage mechanism and the defect of current res- ervoir protection method, after the research of the oilfield reservoir properties, the new type of reservoir protection cleaning up fluid has been developed to prevent reservoir damage. The filed test results show that the flushing clean ing-up fluid as reservoir protection method can effectively reduce formation damage of the well in fluid, and can ef-fectively in eliminate plug existed in the near well region. After workover the production return period becomes short and produced fluid index increased with significant reservoir protection effect. The effectiveness and practicability of this new type of flushing cleaning-up fluid provide a new thought for offshore oilfield production maintained steady and be stimulated.
