中文摘要:ZK2井是重庆市秀山县的一口地热井,在钻进至1674.28 m已达到设计目的层娄山关组,而产水量未达到目的要求。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1674.28 m以深井段采用定向钻进的方案,用随钻测井仪配合弯螺杆,并以滑动钻进与复合钻进相结合的钻进方式调整井斜和方位,从而顺利钻至目标含水靶区内实现了增产增温的目的。

Drilling process for the directional section of ZK2 geothermal well in Xiushan county, Chongqing
Abstract:ZK2 well is a geothermal well in Xiushan county of Chongqing city. It reached the design target formation of the Loushanguan Group at depth of 1674.28m, but the water yield did not meet the requirements. In order to increase the water yield to achieve the purpose of tourism development, new water-bearing target areas were investigated according to geological data and geological means, and a plan for directional drilling from 1674.28m was determined. With the MWD tool and the bent mud motor, the inclination and azimuth of the well were adjusted through the combination of sliding drilling and compound drilling with the well successfully drilled into the target area to increase water production and temperature.
