SIGNIFICANCE OF OIL SHALE IN THE EOGENE PETROLEUM RESOURCE EVALUATION OF THE JIYANG DEPRESSION, THE BOHAIWAN BASIN

摘要: 渤海湾盆地济阳坳陷下第三系沙四段上亚段(Es4(上))和沙三段(Es3)均发育有大量的、含有葡萄藻属与颗石藻属等藻类富集层的油页岩,它们生烃能力极强,是烃类的重要贡献者;侧向运移是油页岩中烃类初次运移的重要方式之一。页理的存在,尤其是油页岩被断层切割时,可能是烃类排出效率大幅度提高的主要原因。研究表明,油页岩具有比暗色泥岩更强的生、排烃能力;在暗色泥岩和油页岩都比较发育的含油气盆地中进行资源评价时,二者不能对等处理,应分开进行盆地模拟和油气资源评价。近年来,在精细油、气-源岩对比的基础上,发现济阳坳陷亿吨级大油田的形成都与沙四段上亚段和沙三段的油页岩有关。济阳坳陷下第三系石油资源评价单独对油页岩进行了盆地模拟和资源量的计算,其石油资源量高达13.8×108t。Abstract: It was found in recent years that the formation of hundred million ton scale of oilfields was related to the oil shale of the lower sub-member of the 3rd member of the Shahejie Formation (for short Es3)in the Jiyang Depression on the bases of the detailed correlation of oil and gas to source rocks, and the important contribution of oil shale to hydrocarbons was understood again. There is a great amount of oil shale containing Botryococcus braunii and Coccolithophorida these algae-enriched layers of great hydrocarbon potential in the upper sub-member of Es4 and Es3 of the Jiyang Depression, it is an important contributor to hydrocarbons. Lateral migration was the important mode of primary hydrocarbon migration in oil shale. The existence of book structure, especially when oil shale cut by faults, was probably the main cause of the great enhancement of hydrocarbon discharge efficiency. Oil shale was separately basin-modelled and calculated in the Eogene petroleum resource evaluation of the Jiyang Depression, and its total amount resources was 13.8×108t.
