Geology of petroliferous basins is a new course proposed by the authors to establish.The present-day research in petroleum geology and the oil and gas prospecting have proved that the sedimentary basins are the foundation units in which oil and gas generate

migrate and accumulate.It has also been proved that to study oil and gas generation

migration

reservoirs

traps

and cap rocks in a basin isolated-ly

and to describe and classify oil and gas accumulation simply can not meet the need of hydrocarbon prospecting.So it is necessary to regard the study of the geology of petroliferous basins as a systematic engineering that all kind of factors are connected with each other.This systematic engineering may be divided into several subsystems as follows:1.Background sys-tem.2.Evolution and deformation system.3.Sedimentary system.4.Hydrodynamic system.5.Thermaisystem.6.Oil and gas system.7.Reformation system.At last

all the achievements in researchof the above subsystems will be synthesized and summarized.Only in this way

the systematic engineer-ing of the petroliferous basins can be a complete system.
