丽水凹陷明下段强制海退体系域油气地质意义

丽水凹陷油气勘探思路正逐步转向“近源下洼”,寻找入洼发育的具有优质物性条件的岩性圈闭是获得油气勘探成功的关键之一。通过地球物理、地质分析等方法在丽水凹陷西次凹明月峰组底部识别出一套强制海退体系域沉积,具有储层物性好,易形成岩性圈闭、有利于捕获油气的有利成藏条件,这类圈闭的探索对油气勘探具有重要的地质意义。

The exploration strategy for oil and gas in the Lishui Sag is gradually shifting towards"near source rock and Lower lying exploration",and finding lithological traps with high-quality physical properties developed in the deep sag is one of the key factors to achieving successful oil and gas discovery.Through geophysical and geological analysis methods,a set of Forced Regression System Tract sediments were identified at the bottom of the Mingyuefeng Formation in the west Lishui Sag,which has good reservoir properties,is easy to form lithological traps,and is conducive to capturing oil and gas.The exploration of such traps has important geological significance for oil and gas exploration.
