Construction of Jingguan ZK1 Geothermal Well and Development & Utilization Plan

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.
