Characteristics of hydrocarbon source rocks in Liaodong Bay area and its main controlling factors

JIANG Xue1,2,ZOU Hua-yao1,2,ZHUANG Xin-bing1,2,TIAN Jin-qiang1,2,YANG Yuan-yuan1,2(1.State Key Laboratory of Petroleum Resource and Prospecting in China University of Petroleum,Beijing 102249,China;2.School of Resource and Information Technology in China University of Petroleum,Beijing 102249,China )  
According to the source rocks characteristics in respect to geochemistry,petrology,sedimentology,tectonic subsidence and ancient climate,the main controlling factors of three sets of Paleogene lacustrine source rocks in Liaodong Bay area were comprehensively analyzed.The results show that the three sets of hydrocarbon source rocks were all with high productivity and formed in warm,moist and anoxic condition.The source rocks in member 3 of Shahejie formation were formed in the environment of deep-water and narrow lacustrine basin with high subsidence rate and the highest productivity.The stratified water column relied on temperature and low salinity.The source rocks in member 1of Shahejie formation were formed in the environment of shallow-water and wide lacustrine basin with low subsidence rate.The stratified water column relied on high salinity.The organic matter was few higher plants.The source rocks in lower Dongying formation were formed in the environment of deep-water and wide lacustrine basin with high subsidence rate.The stratified water column relied on temperature and low salinity.The heterogeneity in the same set of source rocks was controlled by sedimentary facies.The hydrocarbon generating potentiality in member 3 of Shahejie formation is the best,member 1 of Shahejie formation is second and the lower Dongying formation is third.
