摘　　要：针对渤海湾盆地上古生界烃源岩多期叠加演化的特点,以中原地区为例,应用EASY%Ro模拟等方法开展了上古生界热史恢复研究,研究表明,上古生界烃源岩经历了印支期均衡演化和燕山期、喜山期差异演化等多个生烃演化阶段。上古生界烃源岩演化史类型可以划分为回返-沉降增温型、阶梯沉降增温型、W型回返降温-沉降增温交替型、岩浆侵入型、V型回返降温型等五种类型,不同构造单元分别具有不同的烃源岩演化史类型、生烃潜力、生烃高峰期次,其中,回返-沉降增温型、阶梯沉降增温型的地区是古生界的有利生烃区。Based on the characteristics of complicated and multi-stage thermal evolution history,the thermal evolution history and the hydrocarbon generation potential of upper Paleozoic source rock in Zhongyuan has been investigated using EASY%Ro simulation method.The thermal evolution hisory consists of three stages including Yinzhi,Yanshan and Himalaya.There are five types of thermal evolution hisory,such as the elevating temperature of uplifting-subsiding;the elevating temperature of subsiding gradually;the elevating-decreasing temperature alternately in W form;the elevating temperature fiercely by magma intruding;and the decreasing temperature in V form.Therefore the times of hydrocarbon generation and the hydrocarbon generation potential of the source rock differ in these areas with different type of thermal evolutions.Hydrocarbon generation regions are potentially in the regions with the type of elevating temperature of uplifting-subsiding,and the regions with the type of elevating temperature of subsiding gradually.
