摘　　要：济阳坳陷发育两类复式温—压系统,即高压型复式温—压系统和低压型复式温—压系统。主要生烃凹陷同一层段的温—压系统平面分区特征在横向上有较大的变化:高压型复式温—压系统促使与断层有关的油气藏富集在中浅层,低压型复式温—压系统造成与断裂有关的油气藏可以发育在相对深层;高压型复式温—压系统可以产生长距离运移,而低压型复式温—压系统只能发生短距离运移。温—压系统控制油气藏分布,油气藏分布在相对低能区。Two types of complex temperature-pressure systems developed in the Jiyang Depression, which were the overpressure and the underpressure composite T-P systems, respectively. The horizontally regional division characters of the T-P systems in the main sag for hydrocarbon generation at the same layer had a relatively clear variation along the across section, namely, the overpressure composite T-P system resulted in the oil and gas related to fracture congregating abundantly in the shllow-middle layer, while the underpressure composite T-P system caused the oil and gas distributing at the relatively deep layer. The overpressure composite T-P system could migrate a long distance, while the underpressure composite T-P system just migrate a short one. The T-P systems controlled the oil and gas distribution, namely, they distributed in an area with relatively lower energy.
