渤海海域蓬莱9-A油田输导脊研究及应用
|
摘要
根据三维地震、钻井、测井、薄片、包裹体资料及骨架砂体输导脊对比分析,对蓬莱9-A油田潜山不整合面输导脊形成的主控因素进行研究。分析表明,潜山不整合面输导脊的形成主要与潜山的物性和岩性有关,输导脊与构造脊不一定叠合,其中半风化岩石中裂缝发育是横向输导的关键;骨架砂体输导脊受控于高差和浮力,输导脊与构造脊是叠合的;潜山不整合面输导脊可以作为浅层成藏的油气中转站,输导脊圈闭面积、断层与输导脊的配置控制了浅层油藏丰度,输导脊汇油面积越大,断层切至输导脊汇油圈闭的高部位,对应浅层圈闭油藏丰度较高,并在已钻井获得证实。研究表明在无烃源岩覆盖的斜坡区与凸起区输导脊具有重要的控藏意义。
According to the comparison and analysis of 3 D seismic, drilling, well logging, thin section and inclusion data and skeletal sand body transport ridges, a study was carried out on the main controlling factors for the formation of the transport ridges on the unconformity in the buried hill in Penglai 9-A Oilfield. The result shows that the formation of the ridges is mainly related to the physical properties and lithology of the buried hills, the transport ridges and the structural ridges do not necessarily overlap, and the development of the fractures in the semi-weathered rocks is the key to the lateral transport system; the transport ridges are controlled by structural height difference and buoyancy, and they are superimposed with the structural ones; the sand ridges along the unconformity can be used as transfer stations of shallow hydrocarbon accumulations, and the effective combination of trap area on the sand ridge, faults and ridges controls the abundance of the shallow accumulations; if the trap area is larger, and the faults cut into the high of the trap, the abundance of the reservoir in shallow traps is high, and this has been confirmed by drilling data. In addition, it is found that the ridges are important to control hydrocarbon accumulation in the slope and bulge zones uncovered by source rocks.
