静观ZK1号地热井的施工及开发利用计划

Construction of Jingguan ZK1 Geothermal Well and Development & Utilization Plan

摘要:

介绍了静观ZK1号地热井施工概况和设备机具选择，简述了分层钻进措施：采用“三开两固”成井，各次钻具配套，泥浆性能指标，固井工艺措施及抽水试验方法。经测定其井口水温63.5 ℃，由于其井口自流量仅为421.9 m3/d，不便于下一步开发利用，拟定在距原井700 m处再施工一定向井，并提出了定向井的初步设计方案。

Abstract:

This paper introduces the machinery and equipment for geothermal well construction, and describes the stratification drilling measures: 3-section and 2-cementing for well completion, drilling tool matching, mud property, well cementing and pumping test. It was unfavorable for further development and utilization with wellhead water temperature of 63.5 ℃ and flowing yield only 421.9 m3/d. Another directional well was planed to construct 700 m away from the original well; and the design scheme was put forward.
