概述了微型盆地可能成为微型含油气盆地须具备的4个特殊地质条件,即强烈断陷、沉降中心与沉积中心一致、细相带内合适的砂泥岩比和良好的后期保存条件。认为微型盆地是大中型含油气盆地研究的一重要地质窗口,微型盆地综合研究的目的是为大盆地油气勘探服务,应将微型盆地本身的油气勘探放在次要的地位。
This paper summarizes the four special geological conditions that micro-basins may become micro-petroliferous basins. They are strongly subsided, the center of sedimentation is consistent with the sedimentary center, the suitable ratio of sandstone and mudstone in the fine facies belt and good post-preservation conditions. It is considered that the micro-basin is an important geological window for large and medium-sized petroliferous basins. The purpose of comprehensive study of micro-basins is to serve for oil and gas exploration in the Great Basin, and the exploration of oil and gas in the micro-basins should be given a secondary position.
