从吐哈盆地煤成油典型实例出发 ,分析了煤的物性特征及烃类与煤中各级孔隙相互作用机理 .指出烃分子与煤孔隙表面质点相互作用是煤成油排驱的主要制约因素 .煤孔隙分布特征及生烃潜力是制约煤成油排驱的内在因素 ,构造挤压剪切应力是煤成油排驱的外在动力 ;煤成油排驱具有较泥质岩更大的地质色层效应 ,其最有利排驱时期应是Ro 为 0 .9%以前 ;相互连通的孔隙网络及裂隙与输导层如断层相连 ,构成了烃类网络中心的烃类排驱运移出母体的主要通道
Based on the typical coal-to-oil formation in Turpan-Hami Basin, the physical characteristics of coal and the interaction mechanism of pores at all levels between hydrocarbon and coal are analyzed. It is pointed out that the interaction between hydrocarbon molecules and coal surface pores is the main limiting factor The pore distribution characteristics and hydrocarbon generation potential of coal are the internal factors restricting the formation and drainage of coal, and the compressive shear stress is the external driving force for coal-derived oil displacement. Geological chromatography effect, the most favorable drainage period should be Ro was 0.9% ago; interconnected pore network and fracture and the conductive layer such as faults connected to form the hydrocarbon network in the center of hydrocarbon migration from the mother The main channel
