摘要
四川盆地上三叠统须家河组是四川油气勘探的接替层位,具有巨大的勘探潜力,GA地区是川中勘探的重点区块,气藏类型为一构造岩性复合型气藏。利用高分辨率层序地层学技术与地球物理储层反演技术相结合的方法,研究GA地区上三叠统须家河组储层发育规律。结果发现:须四段气藏有利储层主要在GA区块的西部,须六段气藏主要发育在其主体构造部位。
The upper Triassic Xujiahe formation in the Sichuan basin is a follow-up horizon for oil and gas exploration in Sichuan with large exploration potential. GA area in the central Sichuan is a key exploration block. Previous seismic exploration results indicate that gas reservoir of Xujiahe formation in the Upper Triassic belongs to lithologic and structural-lithologic complex gas reservoir. This article mainly researched reservoir rule of the upper Triassic Xujiahe formation with high resolution sequence stratigraphy technology and reservoir inversion technology. We found that the T3x^4 oil reservoir is in the west of the GA area and that the T3x6 oil reservoir lie in the main structure of the GA area. These results instructed the 2D and 3D seismic exploration design directly.
