磨溪构造位于四川盆地乐山-龙女寺古隆起东段南侧斜坡地带,是一轴线为NE-SW向的短轴低平背斜,其总体呈现出缓“S”形,断层不发育。在磨溪构造震旦纪灯影组和寒武纪海相碳酸盐岩中均发现有不同级别的天然气气藏。通过对磨溪构造磨12、磨13、磨17井龙王庙组4575.00~4688.71 m深度取心井段孔洞缝中充填矿物的相对时序关系、裂缝的交切关系,发
The Moxi structure is located on the south slope of the eastern section of the Leshan-Longnv Temple in the Sichuan Basin. It is a short-axis low-lying anticline on the NE-SW axis, showing a slow “S” shape in general with no faults development. There are different levels of natural gas reservoirs in the Moxi Structure Sinian Dengying Formation and in the Cambrian marine carbonates. Through the relationship between the relative time sequence of the filling minerals in the hole seams of 4575.00 ~ 4688.71 m depth of the Longximiao Formation of Grinding Creek Structure Grinding Mill 12, Grinding Mill 13 and Grinding Mill 17, and the relationship of cracks,
