系统是由相互联系、相互作用的若干要素组成的具有一定整体功能的有机整体。系统论是研究客观现实系统共同的特征、本质、原理和规律的科学。遵循系统论思想,成藏理论系统也具有不同层次、不同的结构。含油气系统是指与油气聚集所必需的地质要素和作用。不同的勘探阶段,不同的研究目标及不同的认识程度对理论系统有不同的要求。成藏理论的发展应以“含油气系统”理论为基础,以“复式油气聚集带”理论为指导,反映成藏理论从物质描述—机理分析—规律总结的演化。目前对成藏动态过程研究的深入要求成藏理论系统应以输导体系为主要要素,进而有效预测油气藏。

A system is an organic integer with a certain function, which consists of several factors to be related to and interacting on each other. Systematology is a science studying the common characteristics,nature, principle and regularity of objective reality system. Complying with systematology idea, reservoiring theory system has been studied to have different levels and structures. Petroleum system refers to the geological factors and geological processes which are necessary for oil and gas migration and accumulation. Various exploration stages,research aims and recognitions would have different requirements to theoretical system. Development of reservoiring theory should have be based on theory of petroleum system,be guided by theory of composite hydrocarbon accumulation zone,and reflect the evolution of reservoiring theory to be from materials description-mechanism analysis-regularity summarization. Presently, a further study of dynamic reservoiring processes need the reservoiring theory regarding the migration pathway system as key factor so as to predict effectively oil and gas reservoirs.
