肇294西块2007年投产初期就暴露出含水较高,与临近开发区块同期对比,高出30多个百分点,后期分析得出是由部分井产地层水所致。本文通过对产地层水井水质化学特征、分布特征、构造特征、电性特征进行深入的研究、提出了该区块产水层的识别方法,并给出了治理措施及对策,以便达到降低无效采出,改善区块开发效果的目的。
Zhaoyu 294 West beginning of 2007 put into production higher water exposed, compared with the same period in the vicinity of the development zone, higher than 30 percentage points, the latter part of the analysis is derived from the formation of water wells. In this paper, through deep research on chemical characteristics, distribution characteristics, tectonic characteristics and electrical characteristics of water quality in producing formation wells, a method of identifying aquifers in the block is proposed, and some measures and countermeasures are given to reduce the inefficiencies Out, to improve the effect of block development purposes.
