沉积盆地中的油气藏形成过程这个子系统责无旁贷地应是定量石油地质研究的主要对象。这个系统受控于其周介上地质背景中所包含的一系列物理、化学过程或变量(图略),在这些过程或变量的不同配合下出现不同类型的油气藏或者不出现油气藏。这些在野外和任何实验室里无法观察到的过程,有可能用数学模拟在计算机上作实验而以数符、图形演示出来。 The sub-system of the reservoir formation process in the sedimentary basin should be the main object of quantitative petroleum geology research. This system is governed by a series of physical, chemical processes or variables contained in its geological context (not shown), with or without different types of reservoirs or different reservoirs under different combinations of these processes or variables. These invisible processes in the field and in any lab may be experimentally simulated on a computer using mathematical simulations and graphically illustrated.
