| 1. | The accumulation of oil is governed by lateral changes from permeable to impermeable facies .
石油的储集是受从渗透到不渗透的岩相横向变化控制的。 |
| 2. | Thus, accumulation of oil in the reservoirs occurred after the domes had been sealed by the salt cover .
所以，储集层中的石油聚集作用是发生在穹窿被盐岩盖层封闭之后。 |
| 3. | 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， 。 |
| 4. | Parallel arithmetic numerical simulation and application of secondary migration accumulation of oil resources
油资源二次运移大规模并行数值模拟及其在胜利油田应用 |
| 5. | Sequence stratigraphy model and episodic generation and accumulation of oil - gas reservoirs in laizhouwan sag , bohai gulf basin
莱州湾凹陷层序地层格架及幕式油气成藏 |
| 6. | The development of the fractures has obviously improved the character of reservoirs of ordos basin and controlled the accumulation of oil and gas
裂缝的发育极大地改善了鄂尔多斯盆地低渗储层的储集性能，是控制油气最终就位和聚集的主要因素。 |
| 7. | In view of the three key elements to forming oil - gas reservoir , it is recognized that the principal features of this scientific discipline are the terrestrial origin hydrocarbon generation , repeated migration and compound accumulation of oil - gas , and all these features reflect the complexity of petroleum geologic conditions
从油气田(藏)形成的三环节来看,本学科的主要特点就是陆相生油、再次运移和复式油气聚集,这些特点反映着中国油气地质条件的复杂性。 |
| 8. | ( 2 ) analysis for the forming conditions of hydrocarbon pool , structure and reservoir features shows that the sidaogou structure had two period of migration and accumulation of oil and gas . the first period of migration and accumulation came from the hydrocarbon formed in the source rock of the sanpu depression and formed the asphalt in the sandstone reservoir of triassic and jurassic in the well ha - 2 . the second period came from the hydrocarbon formed in the source rock of triassic round about the well ha - 2 and ha - 3 and formed the hydrocarbon pool in the sidaogou
这是对油藏描述技术和应用领域的完善与补充。通过对四道沟油气藏油气源和油气运移与聚集研究，首次提出四道沟构造存在两期油气运移与聚集，指出了油气生成与运移时期和主运移方向，以及各期油气对四道沟现今油气藏的贡献大小。 |
| 9. | Therefore , qijiagulong sag , daqing placanticline , sanzhao sag and chaochang area are favorable areas to find the accumulation of oil or gas from sourcerock of qingshankou formation . sanzhao sag , gulong sag , qijia sag and heiyupao sag to be f avorable area to find the accumulation of gas from sourcerock deep
因此，在此评价的基础上可得到齐家古龙凹陷、大庆长垣和三肇凹陷和朝长地区是松辽盆地北部扶、杨油层寻找青山口组油气藏的有利地区；三肇凹陷、古龙凹陷、齐家凹陷和黑鱼泡凹陷是松辽盆地北部扶、杨油层寻找深层天然气的有利地区。 |
