靖边气田西部奥陶系风化壳气藏气水关系研究

Study on water relations in Jingbian gas field of Ordovician weathering crust gas reservoirs

近年来,靖边气田西部奥陶系风化壳是鄂尔多斯盆地下古生界勘探的重点领域,也是提交储量后备区块,但是,在勘探过程中出现了部分探井试气产水的现象,给提交储量带来一定的困难,针对这一问题重点分析了出水井的现状与分布情况,水的化学特征系数,在此基础上分析了气水分布的控制因素及分布规律。

In recent years, Jingbian gas field of west of Ordovician weathering crust is the key field Erdos lower paleozoic exploration and reserves, reserve block, but in the exploration process occurred in some wells producing water of the gas test phenomenon, bring certain difficulty to reserves, this paper focuses on the analysis of the status and distribution of wells the coefficient of water, chemical characteristics, based on the analysis of the factors that control the distribution of gas and water distribution.
