Modern petroleum exploration is unthinkable without the aid of magnetism, gravity, and seismic surveys in finding potential petroleum traps.
利用现代石油勘探手段寻找潜在的石油圈闭时，如果没有地磁、重力和地震勘探，是不可想象的。
2.
More specially, physical concepts are required to understand folds, faults, and diapirs, and hence their roles in petroleum entrapment.
更为特别的是，在理解褶皱、断层和底辟以及它们在石油圈闭过程中的作用时需要物理概念。
3.
Both types are known to be productive of oil and gas.
这两类圈闭是盛产石油和天然气的。
4.
It is claimed that more petroleum may be preserved in stratigraphic than in structural traps.
有人主张，地层圈闭也许比构造圈闭存有更多的石油。

6.
Intensely fractured rocks may render traps ineffective by causing leakage.
强烈破碎的岩石造成石油、天然气泄漏而使得圈闭变得不起作用。
7.
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。
8.
A trap is one of the five essential requisites for a commercial accumulation of oil or gas.
圈闭是石油和天然气形成商业性聚集的五大要素之一。

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。
11.
In this way, the subsurface sedimentary structures that trap oil, such as faults, folds, and domes are mapped by the reflected waves.
靠着这种方法，地下沉积岩层中圈闭石油的断层、皱以及穹窿便可由反射波勾绘出来。
12.
Levorsen gave a concise definition of a trap as "the place where oil and gas are barred from further movement."
利温森（Levorson）将圈闭简明地定义为：“阻止石油和天然气进一步运移的地方。”

对川东石炭纪非背斜圈闭气藏的分类
14.
A trap may contain oil, gas, or both.
一个圈闭可能含油、含气、或既含油，又含气。
15.
Anticline and monocline are major trap types.
圈闭类型主要为背斜圈闭及单斜圈闭。
16.
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。
