Title: Thermal History Modeling of Permian Source Rocks in Tanzhuang-Shenqiu Sag
Abstract: Tanzhuang-Shenqiu Sag was located in the central Zhoukou Depression zone,Well Zhou 16 was in the structural high part of western depression.By taking Ro as palaeo-temperature scale,the results of thermal history restoration show that the basal heat flow of Tanzhuang-Shenqiu sag was relatively low at the stage of cratonic platform in Paleozoic.The basal heat flow was elevated with intensive tectonic activities from Indo-Chinese epoch to Yanshanian epoch,which reached maximum values at the end of early Cretaceous.The heat flow decreased and the basin was cooled since the late Cretaceous.The stratigraphic erosion amount of the unconformity surface in Caledonian movement,Indo-China movement,Yanshanian movement and Himalayan movement were 300,1090,1080,600 m respectively,the basal heat flows of each unconformity surface were 48,68,74,50 mW/m2 respectively in corresponding geologic history epoch.The Permian source rocks of Well Zhou 16 entered into early mature stage in 238 Ma,it came into the stage of primary hydrocarbon generation in early-middle Triassic.At the late stage it experiences several stratigraphical uplifting and subsidencing times,the source rocks have secondary hydrocarbon generation in middle late early Cretaceous,it is beneficial to the late hydrocarbon accumulation.
