水井设计与完井工艺改进技术研究

The research of the improvement techniques of well design and construction process

合理的水井设计与完井工艺能提高水井产量、延长水井使用寿命。本文通过对辽河油田矿区水井测井资料与水质化验资料的分析,总结出了含水层视电阻率与地下水矿化度的关系,为水井设计提供了可靠的依据,并在实践中得到了成功应用;PVC-U塑料贴砾滤水管防砂效果好、操作简单,在国外被大量应用。本文阐述了其性能特点并结合修井实践,提出了推广建议。

reasonably well design and well completion technology can improve yields, extend well life. Based on the wells in Liaohe Oil Field , and analysis of water quality logging data and laboratory data this paper summarized the relations of the resistivity of the aquifer and the groundwater salinity, which provides a reliable basis for the well design, and has been successfully applied in practice ; PVC-U plastic perferated pipe has good functions of anti-sand, and easy operated and applied in abroad. It describes its performance characteristics combined the practice and puts forward suggestion for practice.
