摘要

四川盆地寒武系底部和志留系底部各存在一套良好的高成熟度、高有机质丰度、类型好的优质页岩,是页岩气勘探开发的有利目标层系,通过页岩的岩石矿物学、有机地球化学、含气性、物性等特征参数的研究,确定了龙马溪组为现阶段页岩气勘探的重点层系,结合勘探生产实际,提出了页岩气的有利区、建产区和核心建产区的优选方法,经勘探实践证明,方法有效可行。

Abstract

A set of shale with high quality,high maturity,large abundance and good type of organic matter exist at the bottoms of Cambrian and Silurian in Sichuan Basin,which are favorable target of shale gas exploration and development.Through characteristic parameter research of petromineralogy,organic geochemistry,gas content and physical properties,we confirm Longmaxi Formation is the main strata of shale gas exploration at the stage.Combined with exploration and producing practice,we put forward the optimization methods of shale gas favorable area,producing area and core producing area.And practice has proved that these methods are effective.
