【摘要】 随着全球油气勘探与开发技术的不断推进,海洋深水区逐渐成为油气勘探的新热点。海底扇作为深水区油气主要储集体,其独特的深水沉积相模式一直是业内人士关注的焦点,而其沉积相模式的复杂性也是研究者久攻不克的难点。从"深水沉积"研究历史及进展着手,分析不同时期"海底扇"理论的成因机理、沉积模式的异同点,总结了深水沉积研究的不断发展与逐步深入的历程,深水海底扇的成因机理、沉积模式仍是需要继续探索解决的海洋石油地质科学中的难点问题,对深水扇沉积内幕结构的认识已经从早期对现象的描述发展到探究其沉积的动力学机理。同时,基于大量岩心、测井与地震资料,越来越多的接近实际的深水海底扇模型得以建立,为深水油气勘探中海底扇储层的有效预测奠定了基础。更多还原

【Abstract】 With the technologic advancement of oil and gas exploration,deep marine area has become the new hot point gradually.As the main reservoir of the deep water,the exclusive and complex characters of the sedimentary facies model,submarine fan has always been the key topic of depositional experts in the world.On the basic of analysis of the similarities and differences in different periods of "submarine fan" theory and its mechanism,sedimentary model,the characters and improvements of the deep-water sedimentary research are summarized,the study shows that the mechanism and sedimentary mode are difficulties in the offshore petroleum geology field.It is recongnized that sedimentary scientists have already made the most solid step,to the description of the phenomenon and the sedimentary dynamic mechanism during more than a century of research.At the same time,more and more submarine fan modes have been established based on the data of core,logging and seism,which form the effective foundation of reservoir prediction of oil and gas exploration in deep water.更多还原
