含油气盆地的输导体系研究

STUDY ON PASSAGE SYSTEM OF PETROLIFEROUS BASINS

输导体系是泛指某一含油气系统中所有的运移通道及相关围岩的总和。根据油气运移主干道的不同 ,输导体系可分为断层型、输导层型、裂隙型及不整合型等 4种类型。在某一系统中 ,输导体系并非为单一类型 ,而是多种类型的组合。输导体系与油气聚集相辅相成 ,含油气系统的输导体系不同则油气运聚的方式各异 ,反过来油气的不同运聚方式又可以改造甚至形成新的输导体系。由于输导体系具有相对独立性、时空性和复杂性 ,所以在研究输导体系时 ,应综合研究其三维空间形态及以实验和计算机模拟方法研究其输导能力。

A passage system means the total amount of passages within a petroliferous system and its relative country rocks.The passage system could be divided into passage type, fracture type, fault type and unconformity type.A petroliferous system could have a passage system of several types.Different passage systems may result in different oil and gas migration and accumulation patterns,and in turn,the migration and accumulation patterns could reform the old passage system or even form new ones.Since the passage systems are relatively independent,spacio temporal characterisics and complicated,their 3 D space comfigurations and transporting capacities should be studied.
