摘要:
通过总结前人研究结果,利用测井、钻井地质和地化等资料,对冀中坳陷潜山油气藏类型和油气输导体系特征进行研究,并结合已发现的潜山油气藏,建立了不同油气输导体系与潜山油气藏类型的匹配关系。结果表明:根据不同的圈闭遮挡条件,可将冀中坳陷潜山油气藏分为潜山顶、潜山坡和潜山内幕油气藏等3种类型;潜山油气输导体系发育断裂、不整合、内幕溶蚀层和复合型输导体系等4种类型;受碳酸盐岩地层、断层活动性影响以及与油气生成时间的匹配,断裂型输导体系具有高效性和时效性的特征,有利于形成潜山顶和内幕油气藏;不整合型输导体系由不整合上部底砾岩和下部淋浴带组成,具有“双层”输导的特点,有利于形成潜山顶和潜山坡油气藏;内幕溶蚀层型输导体系由潜山内部的溶蚀孔-洞-缝系统组成,其发育程度受内部地层泥质含量控制,有利于形成潜山内幕油气藏;复合型输导体系由单一型输导体系复合形成,具有“多样式”的特点,可以形成潜山顶、潜山坡和潜山内幕油气藏。
Abstract:
Through summarizing the achievement of the formers' research, based on the data of logging, drilling and geochemistry, the types of buried hill reservoir and the characteristics of pathway system in Jizhong Depression were analyzed,and the matching relations between different pathway systems and the types of buried hill reservoirs were discussed according to the discovered buried hill reservoirs. The results showed that the buried hill reservoirs could be divided into buried hill top reservoir, buried hill slope reservoir and inner buried hill reservoir according to the different obstruction conditions of traps; the pathway system of buried hill included fault, unconformity, inner dissolved layer and complex pathway systems; the fault pathway system was effective in terms of space and time due to the influence of carbonate formation, the activity of fault and the accordance of oil generating time, which were favorable to form buried hill top and inner buried hill reservoirs; the unconformity pathway system was constituted of the leached zone beneath the unconformity and the basal conglomerate above the unconformity, which were characterized as double-layer pathway and beneficial to form buried hill top and buried hill slope reservoirs; the inner dissolved layer pathway system was made up of pore-fracture-cave system in the inner formation of buried hill reservoirs which were favorable to form inner hurried hill reservoirs and its development degree was controlled by shale content of interior formation; the complex pathway system was combined with the above single-pathway systems which were characterized as multiform and could lead to hydrocarbon accumulations occurring in different parts of buried hill.
