| 1. | The beds, rich in organic material from which hydrocarbons originated, are called source beds . 富含能够产生碳氢化合物的有机物质的地层叫做生油层。 |
| 2. | These molecules usually have a sufficiently characteristic distribution to permit differentiation between individual source beds and crude oils . 通常这些分子具有特征分布足以鉴别各自的生油层和原油。 |
| 3. | The basinal location of such build-ups places reservoirs in proximity to source beds, and so commonly forms hydrocarbon accumulations . 这种生物建造的盆地位置,使储集层贴近于生油层,因此往往形成烃类聚集。 |
| 4. | Active source bed 有效生油层 |
| 5. | 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。 |
| 6. | 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。 |
| 7. | By studying the material conditions of entrapment , it is conclude that de nan depression is a low - mature oil kitchen , that main source rock of sha san member is partly mature . 2 . the undercompaction starts at the depth of 1300 to 1500 meter 研究取得的认识如下: 1 、成藏条件研究表明,德南洼陷下第三系生油岩成熟度低,主力生油层在洼陷深部进入生烃门限,德南洼陷是一个低熟油灶。 |
| 8. | With the establishment and development of the theory of hydrocarbon generation , the oil and gas migration and accumulation patterns of the " injection migration " and the " injection migration " become the golden rules to explain the relationship of hydrocarbon generation layers and reservoirs 随著生油层理论的建立和发展,油气“上生下储”与“侧向运移”已经成为解释生油层与储集层关系的金科玉律。 |
| 9. | Analysis of petroleum geology , reservoir types and distribution in lujiapu depression indicates that : the forming and distribution of reservoirs had been controlled by source area , source - reservoir relationship , petrophysical characteristics , sedimentary facies and secondary structure , and oil is most abundant in reservoirs around hydrocarbon kitchen ; the upper member of jiufutang formation which was entrained or embedded in the main oil source layer has well developed reservoir and good petrophysical property and is the principle oil - bearing interval ; the mid - fan and fan delta front of nearshore submarine fan is the most favorite facies ; the steep slope of the depression mainly consists of structural reservoirs , the slope belt mainly consists of structural - lithologic and updip pinchout reservoirs , the depressed belt mainly consists of lenticular lithologic reservoirs 摘要对陆家堡凹陷油藏形成的石油地质条件、已知油藏类型及分布的分析认为:生油区、生储配置关系、储集物性、沉积相带和二级构造带控制了油藏的形成和展布,其中围绕生油洼陷的油藏含油最丰富;夹持或嵌入主要生油层中,储层发育、储集物性又相对较好的九佛堂组上段是主要含油层段;近岸水下扇的扇中和扇三角洲前缘是最有利的相带:凹陷的陡坡带以构造油藏为主,斜坡带以构造岩性及储层上倾尖灭油藏为主,深陷带主要为透镜状岩性油藏。 |
| 10. | Terrestrial sediments consist mainly of fluvial and lacustrine facies have the following characteristics : lacustrine basins have undergone a long continuous and fast subsidence and contain many terrestrial source rock sequences ; sedimentary facies of terrestrial basins are deposited in a ring formation . the best source beds are the continental source beds which contain dark shale 陆相沉积以河流湖泊相为主,其基本特征有:长期快速沉降的湖相沉积盆地是陆相生油的发育区;陆相湖盆的沉积相带大都是环状分布,暗色泥岩是最佳生油层。 |
