摘要
酸化井在排液过程中 ,一个很重要的工作是确定地层所产出的液体是地层水还是外来液。基于长庆气田下古主力气层马家沟组口口井需要酸化 ,所产出的液体表现出与地层水性相近而难以确定产出的液体的类型的情况 ,采用简便易行的化学常规分析测得的Cl- 含量和 2Mg2 + /Cl- 系数判别产出液体的类型 ,解决了因地层酸化而难以判定地层是否产水的难题。
In the process of fluid flowing back from a acidized well, it is important that to distinguish whether the fluid flowing back from the acidized well is formation water or is external fluid. Every well has to be acidized in Majagou zone of Xiagu brunt layer of Changqing gas field. It is difficult to distinguish the type of the fluid flowing back the well because its characteristic is close to the local water. A simple conventional chemical method which to measure the content of both Cl - and 2Mg 2+ /Cl -, is presented to solve such a difficult problem.
