| 摘 要： | 根据对川东华蓥山地区陈家湾剖面地质调查,首次发现在飞四段存在滩相鲕粒灰岩地层.通过对该地层岩性、物性、孔隙类型、孔隙结构等特征研究,认为属于鲕粒滩相沉积,储集性能好.飞四段储层以溶孔为主,裂缝次之,属裂缝 溶孔型储层.飞四段滩相鲕粒灰岩储层的发现,为川东地区飞仙关组天然气的勘探提供了新的目的层.

| Abstract: | According to the research of the geological section in the Huayingshan area in East Sichuan, for the first time, it was found beach-facies oolitic limestone layer was found existing in Member 4 of the Triassic Feixianguan Formation (T 1f~4). Through the research on strta features such as lithology, petrophysical property, pore type, pore structure, etc., the oolitic limestone layer was thought to belong to oolitic beach-facies sediments with good storage performance. The storage rooms of the reservoir rocks in T 1f~4 are mainly the solution cavities, and the fractures take second place, it belongs to the fracture-solution cavity reservoir.The discovery of beach-facies oolitic limestone reservoir in T 1f~4 offers a new exploration target zone for gas exploration in Feixianguan Formation in East Sichuan. |
