六盘山盆地白垩系油气地质条件及有利区预测
Petroleum Geological Condition of Cretaceous in Liupanshan Basin and Favorable Areas Prediction
摘要
Abstract
Liupanshan Basin is located in the joint of southwestern margin of North China block and Qilian-Qinling structure belt. It′s under a complex system. According to field investigation,there distribute much oil and gas of Cretaceous,which indi-cates that the basin has oil production potential. But the entire basin is of low degree of prospecting,and great differences exist in research data and in determination of target layers of exploration. Using field investigation,experimental analysis methods and gravity-magnetic materials,in-depth research and evaluation are made on development situation of the hydrocarbon source rock and characteristics of reservoir and reservoir−forming combination in Cretaceous reservoir,and we get the breakthrough findings:Liwaxia group belongs to class III medium reservoir,and Madongshan and Naijiahe groups belong to class IV the poor reservoir;large sets of sandstone development in Paleogene can be a favorable Cretaceous reservoir of oil and gas;organic matter of the hydrocarbon source rock is of sapropelic-mixed type with high degree of thermal evolution,and is favorable for hydrocarbon generation. Three kinds of exploration areas and five favorable local tectonic positions have been predicted. The research results have an important guiding significance to further exploration of oil and gas in Liupanphan Basin.关键词
