对油气藏分类的几点认识

Some Cognitions for the Classification of Reservoirs

油气藏的分类方法有多种。认为为油气勘探服务的分类应着眼于油气藏的形成原因、几何特征及其位置特征。提出油气藏的分类 ,应该按照圈闭形成的三大因素即构造、地层和流体 ,划分为构造油气藏、地层油气藏和流体封闭型油气藏。具体分类应该结合形成油气藏的圈闭的各个控制因素甚至是油气生成和运移时间进行考虑.

There are many kinds of ways to classify reservoir. The classification for the service of oil and gas exploration should focus on how reservoir have been formed, what geometry features they have as well as what location features they have. It has been pointed out that the classification of reservoir should follow the three factors— structure, stratum and liquid—so as to be divided into structural reservoir, stratigraphic reservoir and liquid blocked out reservoir. Each classification should be considered according to the different controlling factors that have formed the traps for reservoir, even according to the time when oil and gas were formed and moved.
