四川天然气井钻井压力控制

PRESSURE CONTROL OF NATURAL GAS DRILLING IN SICHUAN

基于压力控制在油气井钻井中的重要位置 ,文章结合四川地区天然气井钻井压力控制中的实践 ,从 4个方面谈自己的认识与建议。即 :压力控制是油气井钻井工程的核心技术 ;压力控制的前提是搞好地层压力预报与监测 ;气井比油井压力控制难度大 ;四川在压力控制上的几个具体作法。

Owing to the importance of pressure control to oil and gas drilling, the understanding and suggestions on several aspects are proposed in the paper in combination with its practice in Sichuan, i. e. the pressure control is a key technique of oil and gas drilling; the premise of pressure control is to predict and monitor formation pressure in time; the pressure control of gas well is more difficult than that of oil well; and some concrete methods adopted in Sichuan are introduced.
