摘要
近10年来,在高天然气价格、水平井钻井技术和压裂技术进步的推动下,页岩气成为美国最重要的天然气开发目标,形成了适合于不同勘探开发阶段的页岩气资源潜力评价方法,对页岩气资源的认识不断得到深化。在详细研究美国页岩气资源评价方法基础上,探索了我国现阶段页岩气资源评价方法,并针对四川盆地西南部地区及威远气田区下古生界下寒武统筇竹寺组的页岩气资源做了初步预测。结果认为四川盆地页岩气资源丰富,不少于盆地常规天然气资源量,是未来值得重视的重要天然气勘探开发新领域。
In recent 10 years,with the promotion of high natural gas price and advancement of horizontal well and fracturing techniques,shale gas resource has become the most important development object in the United States,thus forming an evaluation method on shale gas resource potential suitable for varied exploration and development stages,which made it increasingly improved to acknowledge shale gas resource.Based on researching into the American shale gas resource evaluation method,we probed into the evaluation method nowadays in China and have done the primary prediction on shale gas resource in southwest Sichuan basin and Lower Cambrian Qiongzhusi formation of the Lower Paleozoic in Weiyuan gas field.It is believed that the Sichuan basin is an important new region worthwhile to be paid more attention in the field of natural gas exploration and development in future since it is rich in shale gas resource,the reserves of which is no less than that of conventional natural gas resource.
