Abstract:

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.

Key words: reservoiring theory, systematology, petroleum system, structure, key factor, pathway system
