With incomplete information, oil and gas trap system is a kind of grey system, the process to get and to quantify the parameters used to evaluate trap system has great uncertainty, in another word, these parameters are grey parameters, grey classification is just a good solution to this kind of problems.
含油气圈闭系统是一种信息不完全的灰色系统，赖以评价圈闭系统的各项参数的原始获取和定量化过程都具有很大的不确定性，也就是说，这些评价参数都是灰参数，灰色聚类恰恰是解决这种确定性差的多参数评价问题。

Anticline and monocline are major trap types.
圈闭类型主要为背斜圈闭及单斜圈闭。
In other words a trap is still a trap whether it is barren or oroductive.
换句话说，不管圈闭内是否含有油气，圈闭就是圈闭。
commercial trap

Perhaps it would be more accurate to say that they search for potential traps. Only after drilling and testing is it known whether the trap contains oil or gas.
但准确地讲，他们寻找的是潜在的圈闭，只有在钻井和试油以后才知道圈闭内是否含油或含气。
Stratigraphic and structural traps abound in most sedimentary basins. Thus oil is not an unusual geological product.
在大多数沉积盆地中，构造圈闭和地层圈闭是很多的，所以石油并不是一种不常见的地质产品。
