The results have shown that the es4 shale and es4 mudstone have different hydrocarbon generation patterns 在洼陷中心，这两个生油峰分别出现在23my与7my 。
Using this method , the petroleum - generating amounts and the petroleum resource amounts of the es4 shale distr 总生油量为17 . 386亿吨，预测资源量为4 . 346亿吨。
Heat up 4 tbsps of oil in a wok , deep fry the chicken until cooked . then , let the extra oli drained for a few minutes 在镬中加入大约4汤匙生油，烧热后放入鸡肉；炸熟后沥乾油分，待用。
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。
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。
The es4 shale has two oil - generating peaks , occurring at the geological temperature of 105 and 140 , respectively , corespondent to vro of 0 . 53 % and 0 . 95 % 第一峰产率约占总油产率的10 - 15左右，第二个生油峰占80 - 85左右。
Terrestrial sediments can be found in shengli oil filed beginning from permian to tertiary . in addition , source beds are widely distributed 胜利油区从古生代二迭纪到新生代第三纪每个地质时期都有陆相沉积，也广泛地发育着生油层。
Better reservoirs are developed in lowstand systems tracts while better source beds and cap rocks are developed in transgressive and highstand systems tracts 低位体系域发育分选良好的储层，而水进体系域和高位体系域沉积则往往是良好的生油层和盖层。
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。
In sum , since xianhe block is located in the area between hainan and qingshui depressions , it has the exclusive advantage of getting hydrocarbons from the two depressions 总之，由于本区位于海南、清水两大生油凹陷之间，位置优越，应该具有得天独厚的油源条件。
