中文摘要:ZK2 井是重庆市秀山县的一口地热井,在钻进至1674.28m已达到设计目的层娄山关组,而产水量未达目的要求。为了增加产水量从而达到旅游开发的目的,根据地质资料和地质手段重新寻找新的含水靶区,并确定了在1674.28m以后井段采用定向钻进的方案,从而顺利钻至目标含水靶区内实现了增产增温的目的。

Application of the drilling process of the directed well section of ZK2 well in Xiushan County, Chongqing
Abstract:ZK2 well is a geothermal well in xiushan county of Chongqing city, which has reached the design level of Lou shanguan group in 1674.28 M, but the water production did not meet the requirements. In order to increase the amount of water produced so as to achieve the purpose of tourism development, new water-bearing target areas have been re-searched according to Geological data and geological means, and a plan for targeted drilling in the well section after 1674.28 M has been determined. Thus, the goal of increasing production and increasing temperature was achieved by successfully drilling into the target area.
