摘　　要：本文介绍的新型测量系统用以测量深层气探井井底压力、温度, 起钻后对数据进行分析处理,能够解决井底压力精确控制问题, 为大庆深层钻井完井设计施工提供准确的井下数据, 同时建立了一种新的随钻气层解释方法。该系统结构简单, 成本低, 应用该系统完成了外围两口深层气探井的钻井作业, 其中一口深井完井压裂后获得工业气流。A new type of measuring system introduced in this paper can measure the bottom hole pressure and temperature of deep gas exploration well,analyze and process the data after tripping out.It can solve the problems for controlling bottom hole pressure accurately and provide accurate data for deep well drilling and completion design of Daqing Oilfield.At the same time this paper sets up a new interpretation method for gas formation well drilling.This system has a simple structure with low cost.It is applied in two deep gas exploration well’s drilling operation in peripheral oilfield.One well has obtained commercial gas flow after fracturing.
