针对滇黔桂海相"多、残、高、广"的石油地质特点,对滇黔桂地区海相含油气盆地区域构造、沉积、生储盖层、保存条件、油气动态成藏、资源及圈闭等方面进行分析,总结该区的油气成藏基本条件,并根据最新勘探成果对该区近年的3口重要探井进行钻探成效分析,提出滇黔桂海相新区今后油气勘探与综合研究的思路、方向与重点。

In this paper,the regional tectonics,sedi mentation,source-reservoir-overlying formations,pre-servation conditions,hydrocarbon accumulation and resource extent about the marine oil-and gas-bearingbasins in Yunnan-Guangxi-Guizhou Region were discussedin accordance with the petroleumgeologic char-acteristics of the basins.The main conditions of oil and gas pool forming in the basins were summed up,and the drilling effect analysis on the recent three i mportant exploration wells in the basins was made.Then,the direction and focal points of oil and gas exploration as well as the ideas of comprehensive re-search about the marine basins in Yunnan-Guangxi-Guizhou Region for the future were put forward.
