南黄海盆地中、古生界油气地质条件研究

南黄海盆地在以中、新生界为主开展的油气勘探历时近30年，至今未获工业油气流。而盆地中、古生界石油勘探程度很低．目前仅只有少数钻井钻遇中、古生界，对其基本油气地质条件认识存在不足。此文运用含油气系统理论和盆地模拟技术，利用钻井资料，类比下扬子陆区石油地质条件研究成果，对下扬子南黄海盆地中、古生界海相地层烃源岩、储层和盖层条件进行了初步研究，为该盆地中、古生界下一步油气勘探指出了有利方向。

Study on the Petroleum Geologic Conditions in Mesozoic-Paleozoic Strata in the South Yellow Sea Basin

Hydrocarbon exploration has been conducted in South Yellow Sea Basin for nearly 30 years, with Mesozoic-Cenozoic strata as the main exploration targets, but no commercial oil ＆ gas flows have been discovered. The degree of exploration in Meso- zoic-Paleozoic is still very low, and the Mesozoic-Paleozoic strata were penetrated only in a few wells. Therefore, the understandings about the basic geologic conditions in Mesozoic-Paleozoic strata are still poor. On the basis of the petroleum system theory, with well drilling data and using basin modeling techniques, comparion has been conducted with the study results about the geologic conditions in the Lower Yangzi continental areas, and a preliminary study about the petroleum geologic conditions for HC accumulation, mainly source rocks, reservoirs and seals in Mesozoic-Paleozoic marine strata in the Lower Yangzi areas of South Yellow Sea Basin has been finished, and favorable exploration targets for next exploration in Mesozoic-Paleozoic have been proposed.
