柳州地区页岩气地质调查井钻探技术研究与应用
Research and application of drilling technology for shale gas geological survey wells in Liuzhou area
摘要
Abstract
Shale gas formation have developed fractures and poor cementation,manifested as rock fragmentation,poor water sensitivity,and low wellbore strength.During the drilling process,it is easy to encounter complex situations such as collapse,falling blocks,and diameter reduction,which can lead to instability of the wellbore,drilling jamming,and buried drilling accidents inside the hole.Research on deep exploration drilling technology for the geological survey well engineering of the shale gas geological survey project in Liuzhou,Guangxi,and the application of PVA1788 film-forming system without solid flushing fluid and film-forming anti collapse system without solid flushing fluid,rope coring fluid dynamic hammer drilling technology,new technology for expanding corrugated pipe wellbore protection,and directional drilling correction technology for screw drilling tools.Good construction effects have been achieved in a number of field applications.关键词
