摘要
页岩气这一非常规油气资源的开发近年来受到了人们的高度重视,在页岩气钻井中,为了更好应对高摩阻问题和井壁失稳问题,人们一般选择油基钻井液。由于人们的环保意识在不断增强,石油公司一直在尝试着研发能够代替油基钻井液性能的水基钻井液。本文主要介绍了页岩气地层的特性,阐述了页岩气水基钻井液技术难题,并提出了相应的技术策略,旨在为人们提供一定的参考。
In recent years,the development of shale gas,an unconventional oil and gas resource,has received great attention.In shale gas drilling,in order to deal with the problem of high friction and the instability of wellbore,oil-based Drilling fluid.As people's awareness of environmental protection continues to grow,oil companies have been trying to develop water-based drilling fluids that can replace oil-based drilling fluids.This paper introduces the characteristics of shale gas formations,expounds the technical problems of shale gas water-based drilling fluid,and puts forward corresponding technical strategies aimed at providing some reference for people.
