分层注水是解决油田开发过程中层间矛盾，实现有效注水，提高水驱动用程度及采收率的重要手段，而分注井作业的成功与否直接关系到分层注水效果的好坏。本文通过对长庆超低渗透油田分注现状进行调研，分析了影响超低渗透油藏分注井作业成功率低的主要原因，并针对存在问题开展了小卡距分注、免投死水嘴以及测调一体化工艺研究与应用，现场试验成功率100％，有效地提高分注井作业成功率。
分層註水是解決油田開髮過程中層間矛盾，實現有效註水，提高水驅動用程度及採收率的重要手段，而分註井作業的成功與否直接關繫到分層註水效果的好壞。本文通過對長慶超低滲透油田分註現狀進行調研，分析瞭影響超低滲透油藏分註井作業成功率低的主要原因，併針對存在問題開展瞭小卡距分註、免投死水嘴以及測調一體化工藝研究與應用，現場試驗成功率100％，有效地提高分註井作業成功率。

Stratified water injection is to solve the contradiction between the middle of the oil field development process to achieve effective water injection,to improve an important means of water driving the degree of recovery,while the sub-injection wells operating success of a direct relationship to the stratified injection effect of good or bad. In this paper, ultra-low permeability in Changqing Oilfield separate injection status quo research analyzed the effect on the main reason for low success rate of sub-injection wells operating,and problems to car- ry out the technology and application to a small card from the separate injection, free vote in the dead tap cast and test deployment of integration, the success rate of 100 % in field test , effectively improve the success rate of sub-injection wells operating.
