大山铺矿区外溢天然气成因及治理工艺探讨

Discussion on the Causes and Treatment Technique of Natural Gas Overflow in Dashanpu Mineral District

大山铺岩盐体位于四川盆地自流井构造东南冀,矿山于1971年开始建设。2008年,该矿山岩盐资源开采殆尽,全面停止生产。近年来,区内发现天然气外溢。本文通过对大山铺矿区地质资料进行收集分析,确定了天然气外溢的原因,提出了卤井分类治理措施。

mDashanpu rock salt district is located in the southeast of Ziliujing which is in Sichuan Basin. The mineral district was established from 1971, and in 2008, the rock salt resources in this district have been ran out and stopped production from then on. In recent years, the natural gas overflow has been discovered in this district. This paper through collection and analysis of the geological data of Dashanpu mineral district confirms the causes of overflow and comes up with some measures to classified managing brine wells.
