摘要
In order to speed up the hydrocarbon exploration proceeding in Shuguang-Leijia area of west depression of Liaohe basin, according to classification method of subtle reservoirs, subtle reservoirs of the area have been classified into two kinds, which are the Pre Cenozoic buried hill reservoirs and the Paleogene special lithologic reservoirs, based on the hydrocarbon exploration results. Based on comprehensive study of the geological background, reservoir-forming condition and accumulation process of subtle reservoirs within the whole area, it is regarded that the geological conditions to form subtle reservoirs are favorable, such as multiple tectonic movement, complex tectonic background, favorable source conditions, cap rock with good feeling capacity, unblocked and multiple migration-accumulation systems. The result shows that two kinds of subtle reservoirs have the petroleum geological and dynamic characteristics of the good matching conditions of source, reservoir, cap, trap, migration and accumulation.
