影响气体钻井地层出水因素

Effect factors of the water production formation on the gas drilling

气体钻井具有钻速高,成本低,环保性好等优势,但地层出水极易导致井下情况复杂,严重制约了空气钻井技术的推广应用。本文总结了空气钻井地层出水的危害,介绍了地下水的分布情况,分析了影响地层出水的因素,对气体钻井现场施工有一定的指导意义。

The gas drilling has some advantages, such as high penetration rate, low cost, and good environmental protection, etc. However, if it encounters the water production formation, the downhole complicated situation which appears easily will seriously restrict the application of gas drilling technology. In this paper the harm of the water production formation on gas drilling is generalized, the distribution of groundwater is introduced, and the effect factors of the water production formation on gas drilling is analyzed, it has a certain guidance significance on gas drilling construction.
