【摘要】 按照整体研究、局部深入再回到整体的"时—势—体—面—点—面"的工作新思路,采用多因素叠合分析的方法,可以有效恢复沉积期岩相古地理环境.应用该方法,克服了先局部后整体导致的岩心、测井、地震等定相的多解性,充分考虑了宏观沉积背景在定相中的作用,厘定了歧口凹陷沙三2亚段沉积相类型.更多还原

【Abstract】 A new sedimentary system analysis method is proposed,which can be denominated "the multifactor superposition analysis".This approach begins with the overall structure of researched area,then plays emphasis on some important parts,finally returns back to the whole researched area.Since the role of sedimentary background in identifying macro-facies types is fully considered,this new method effectively overcomes the multiplicity in identifying macro-facies types based on core,logging and seismic data using the sedimentary system analysis method from parts to whole.The method is applied to the sedimentary analysis of Es3 of Qikou Sag and effectively guides the determination of sedimentary facies types and sedimentary system of Es3 in Qikou Sag.更多还原
