摘要
四川盆地志留统龙马溪组和寒武统筇竹寺组页岩气勘探前景乐观,但是目前研究资料相当缺乏,通过调研国外尤其是北美地区关于页岩气勘探开发方面的文献资料,分析了美国页岩气藏的开发规律,并将四川盆地内尤其是蜀南地区龙马溪组和筇竹寺组两套页岩的地质参数与美国页岩气藏进行了对比分析,再根据四川盆地页岩气特征,利用已投入开发的页岩气井资料类比美国页岩气开发规律,确定了四川盆地页岩气的单井初始产量、递减率等开发指标,并初步预测了页岩气的开发规模。
There is an optimistic outlook for shale-gas prospect in Silurian Longmaxi Formation and Cambrian Qiongzhusi Formation, Sichuan Basin. But, their data are considerably scarce. By investigating plenty of litera-tures on shale-gas E & P from abroad, especially from North America, we analyzed the shale-gas development rules in USA, compared some geological parameters from Sichuan Basin, in particular both Longmaxi and Qiongzhusi forma-tions, with those of some shale-gas reservoirs in USA, determined many development indices of initial production and decline rate for single well of shale gas in Sichuan Basin, and preliminarily predicted its development scale.
