摘要
页岩气是一种具有良好开发前景的非常规天然气资源,能够对常规油气资源进行有效补充。文中对陕西省西乡—镇巴地区实施的页岩气地质调查项目区内的构造、岩性特征和已钻井资料进行了分析,提出了探井施工可能遇到的难点与对策。
Shale gas,a kind of unconventional natural gas resources,has a great development prospect,which can effectively supplement conventional oil and gas resources.Based on analysis of the data obtained from well drilling and analysis of structures and lithologic features in the geological investigation area for shale gas exploration,which was involved in the gas exploration project commenced in Xixiang-Zhenba area of Shaanxi province,the difficulties possibly encountered and the countermeasures are put forward in this paper.
