摘要
quot;EnDivSummary">Based on a study of main factors controlling hydrocarbon pooling of Quan4 Formation in Longxi area of Songliao Basin, the authors hold that oil and gas generated from hydrocarbon source rock of Qing1 Formation mainly migrate into Quan4 Formation in two ways. One is the downward migration of oil and gas generated from hydrocarbon source rock of Qing1 Formation along the faults into Quan4 Formation under the large below-source pressure difference. The other one is the lateral migration of oil and gas generated from hydrocarbon source rock of Qing1 Formation into Quan4 Formation under the conditions of upward-inclining lateral connection of hydrocarbon source rock of Qing1 Formation to Quan4 Formation caused by fault activity.
