| 1. | Identification of source rocks by quick methods, and quantitative evaluation of their petroleum potential can be done either in the laboratory or on the well-site .
无论在实验室或井场都能用快速方法鉴别生油岩并对其生油能力作出定量估价。 |
| 2. | Active source rock
有效生油岩 |
| 3. | Steranes and terpanes in high mature - over mature oil and source rock cannot be identified well because of their quite low content
对于高成熟过成熟的原油和生油岩，由于甾萜类化合物含量大低往往鉴定效果不好或根本检测不到。 |
| 4. | Steranes and terpanes exist in saturated hydrocarbon component of oil and source rock , and they are usually identified by gas chromatogram - mass spectrum
甾萜类化合物存在于原油和生油岩的饱和烃组分中，通常用色谱质谱法鉴定。 |
| 5. | It was noted that the upper mesozoic strata ( mainly cretaceous ) as revealed by drill or dredge from the eastern nansha waters might extend into the hinterland of the nansha waters
南海裂谷期间形成的下第三系具有明显的裂谷充填特徵，其构成生油岩主体。 |
| 6. | Studies on the combination of source rocks and reservoirs show that yuejin - dongchaishan , dafengshan and the front part of arjinshan area are the most favourable areas for oil and gas accumulation
根据生油岩及储油岩叠置组合关系，指出阿尔金山前地区、跃进东柴山地区、大风山地区是有利油气聚集区。 |
| 7. | 5 . platform trough and basin with deep water and low energy are the favorable source rock zones , reef banks and reef cores are the profitable reservoir . and the strata which is dolomitized is the main gas yielding parts
5深水低能沉积的台沟、盆地相是有利的生油岩相带，浅水高能的礁滩、礁核相是有利的储层，产气段主要是生物礁内的白云岩段。 |
| 8. | Oil - source correlation analysis has shown that the oils were mostly from ed2 source rocks from the bozhong depression , and the oils occurred in the slope hidden hill belt were from es3 or / and es , source rocks in the bozhong depression
油源对比结果表明东斜坡带东营组原油来源于渤中凹陷ed _ 2暗色泥岩，斜坡潜山带原油来源于渤中凹陷es _ 3或es _ 1生油岩。 |
| 9. | The hydrocarbon groups , alkane hydrocarbons and biological markers in the crude oils and the oil source rocks have closed relationships , which has shown that zifusi lw - lying area has a better oil source condition and oil source potentiality
在原油和生油岩中烃类族组分、烷烃和生物标志物之间均有较好的亲缘关系，表明资福寺洼陷具有较好的生油条件和生油潜力。 |
| 10. | The correlation of oil - oil indicated that the oil can be devided into three species at least ; the correlation of oil - source rock indicated that there are three sets of source rock , namely cambrian - ordovician , carboniferous - permian and jurassic system
油油对比表明原油至少可分为三类；油源对比表明有三套烃源岩，即寒武奥陶系、石炭二叠系和侏罗系生油岩。 |
