| 1. | 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。 |
| 2. | All three basins are enclosed by the 1900m depth contour . 三个海盆都被1900米的等深线所圈闭。 |
| 3. | Hydrocarbous are thus trapped and cannot escape either updip or vertically . 因此烃类被圈闭,无论在上倾方向或垂直方向都不能散失。 |
| 4. | The most common structural targets associated with oil entrapment are anticlines and faults . 与储油圈闭有关的最一般的构造目标是背斜和断层。 |
| 5. | 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. | Within such deposits there may be numerous potential traps for oil and gas in separate sandstone bodies . 在这种沉积中的散砂岩体内,可能有许多潜在的油气圈闭。 |
| 7. | Both types of traps are identified and analyzed best in the subsurface by relating them to lighologic time marker . 这两类圈闭根据其与岩性时间标志层的关系而极易进行地下的鉴定与分析。 |
| 8. | The outcrop of the bed is then drawn through the intersecting contour points bearing in mind the closure directions anticipated from the rule of vs . 考虑到V字形法则预计的圈闭方向,通过等高线交点勾出岩层的露头线。 |
| 9. | The highest point of a trap is the crest , or culmination 含有烃类的那部分圈闭的最低点称为溢出点。 |
| 10. | This situation is particularly significant in hydrodynamic traps 这种情况对于水动力圈闭尤其有意义。 |
