Abstract

In recent years, several condensate reservoirs supplied with hydrocarbons from Carboniferous-Permian coal-measure source rocks have been identified in the Bohai Bay Basin, showing considerable exploration potential. To address the problems of poorly understood hydrocarbon generation characteristics and unclear exploration directions in the study area, it is urgent to reconceptualize the hydrocarbon supply capacity of coal-measure source rocks. To this end, the Huanghua Depression in the Bohai Bay Basin was taken as the research object, and the spatial distribution, hydrocarbon generation potential and hydrocarbon generation characteristics of different lithologies of coal-measure source rocks in the Huanghua Depression were comprehensively analyzed through multivariate data statistics such as cores, well logging, mud logging and oil production testing, based on the analysis of the difference of sedimentary filling characteristics of tectonic units in the basin, and the evaluation model of sedimentary units established by using the numerical simulation technology for the basin.The hydrocarbon generation pattern of Carboniferous-Permian coal-measure source rocks in the Bohai Bay Basin was clarified, and a favorable hydrocarbon accumulation zone in the study area was predicted. The result shows that for the Carboniferous-Permian coal-measure source rocks in the Huanghua Depression, the coal rock is the marker bed, and three types of hydrocarbon generation lithologies are developed: mudstone, carbonaceous mudstone and coal rocks, among which the mudstone is thick and continuous with high hydrocarbon generation potential; the hydrocarbon generation simulation shows that the primary hydrocarbon generation is dominated by oil production from mudstone, and the secondary hydrocarbon generation is dominated by mixed oil and gas production from various hydrocarbon source rocks; three types of hydrocarbon generation patterns are developed: early subsidence type, late subsidence type and continuous subsidence type, and the hydrocarbon generation areas of continuous subsidence and late subsidence types are the most favorable for in-situ oil and gas accumulation in the buried hill. The results of the study can provide technical support and data for theoretical research and exploration deployment of oil and gas accumulation by hydrocarbon supply from coal-measure source rocks in the study area.
