| 摘 要： | 在研究新疆库车坳陷逆掩断裂、源岩和盖层空间发育特征的基础上,研究了逆掩断裂与源岩、盖层的空间匹配关系.认为断穿源岩、盖层的逆掩断裂则是油气散失的通道;勾通源岩,但未断穿盖层的逆掩断裂则是油气聚集的输导通道,它们控制着库车坳陷油气的聚散及其在空间上的分布.在研究库车坳陷逆掩断裂活动史和源岩排烃史、盖层封闭能力形成史的基础上,研究了逆掩断裂与源岩、盖层的时间匹配关系,认为盖层与源岩的时间匹配关系控制着可供运移的油气量;逆掩断裂与源岩的时间匹配关系控制着可供聚集的油气量,盖层与逆掩断裂的时间匹配关系控制着油气的富集量.

| Abstract: | Based on the space development characteristics of thrusts and the space development characteristics of caprocks and sourcerocks,this paper studied the space matching relation among the thrusts,caprocks and sourcerocks.The thrusts that faulted sourcerocks and caprocks are the transporting passages of oil and gas losing,while the thrusts that connected sourcerocks,but did not fault caprocks are the transporting passages of oil and gas accumulation.They control the accumulation and losing of oil and gas and their destruction in Kuche Depression.Based on the active history of thrusts,the hydrocarbon-expulsion history of sourcerock and the sealing history of caprock for oil and gas,this paper studied the time matching relation among thrusts,caprocks and sourcerocks.The time matching relation between sourcerock and caprock controls the oil and gas migration amount,and the time matching relation between thrusts and sourcerock controls the gas and oil accumulation amount,and the time matching relation between caprock and thrusts controls the oil and gas preservation amount. |
