摘要(Abstract)：

为了研究含油气盆地内断裂附近油气分布规律,在输导断裂主要特征部位发育及其确定方法研究的基础上,通过输导断裂主要特征部位与油气运移关系分析,以松辽盆地西部敖古拉断裂为例,就输导断裂主要特征部位对油气运移控制作用进行了研究。结果表明,输导断裂主要特征发育部位对油气侧向运移控制作用主要表现在3个方面:(1)输导断裂转换带发育部位是油气侧向运移穿过输导断裂的有利部位,因为转换带处砂体发育,形成穿过输导断裂侧向运移的输导通道,油气沿其穿过输导断裂侧向运移;(2)活动期输导断裂伴生裂缝相对发育部位是油气沿断裂垂向运移的有利部位,因为活动期形成的伴生裂缝孔渗性明显优于其围岩,是沿输导断裂垂向运移的有利部位;(3)输导断裂凸面脊发育部位是其停止活动后油气垂向运移的有利部位,因为断裂停止活动后,伴生裂缝已紧闭愈合,凸面脊是油气沿填充物孔隙向上运移的汇聚部位,是油气沿输导断裂垂向运移的有利部位。
In order to study the distribution law of the oil and gas near the faults in petroliferous basins, on the basis of the researches on the developed parts of the main characteristic parts of the transporting faults and their determining methods, the controlling actions of the main characteristic parts of the transporting faults on the migrations of the oil and gas were figured out by analyzing the relationships between the parts and migrations and taking Aogula Fault in West Songliao Basin as an example. The results show that the controls on the oil and gas lateral migrations are mainly manifested in the following three aspects for the main characteristic parts of the transporting faults:the developed parts of the transporting fault transition zone are the favorable parts for oil and gas lateral migration through the transporting faults, because the sandbodies in these parts are well-developed and the transporting paths of the lateral migration through the transporting faults are prone to form;the corresponding well-developed parts of the associated fractures of the transporting fault in the active stage are favorable for the vertical migration of the oil and gas along the faults, because the porosity and permeability of the associated fractures formed in the active stage are obviously better than those of the surrounding rocks;the developed part of the convex ridge is the advantageous part of the vertical migration of the oil and gas after stopping the activities, because the associated fractures have been closed and healed after stopping the activities, the convex ridge is the convergence part of the oil and gas migrating upward along the pores of the filling materials, and furthermore is the advantageous part of the oil and gas migrating vertically along the transporting faults.
