对地热钻井进行广泛深入的研究，必须对所有各种类型的热储的不同钻进技术工艺的现状进行一次回顾。本文所提供的材料将对以下一些主题进行讨论：钻进前应考虑的各种因素，钻井程序细节、钻井液、水泥固井、井口装置、防喷器的配置以及在地热钻井中逐渐推广的某些应特殊考虑的内容等等。为了清楚地讲述钻进操作与后勤支援工作，本文对气控热储和液控热储将分别进行讨论。
Extensive research into geothermal drilling requires a review of the current status of different drilling technologies for all types of thermal storage. The material presented in this article will discuss some of the topics that should be considered before drilling, details of drilling procedures, drilling fluids, cementing, wellhead arrangements, BOP configuration, and the gradual promotion of geothermal drilling Some should be considered special content and so on. In order to clearly describe the drilling operation and logistics support work, this paper on the gas-controlled thermal storage and liquid heat storage will be discussed separately.
