Recognition and Petroleum Geological Meaning of Deepwater Sub-Lacustrine Fan: Qing1 and Qing2 Group, Yevgtai-Talaha Area, Northern Son-Gliao Basin, China
摘要
With the comprehensive application of drilling data and 3D seismic data, a series of deepwater sub-lacustrine fan have been discovered in Qingl and Qing2 Group, Yingtai-Talaha area. Largely controlled by the western slope belt, the sublacustrine fans of 447 km2 in area are oriented southnorth displays lenticular shape in space distribution. Due to the favorable condition of hydrocarbon source rocks and well relationship of reservoir-cap rock, the deepwater sub-lacustrine fans have a huge petroleum exploration potential and can never be ignored in Songliao Basin.
