测井资料反演南海北部陆坡渐新统的矿物组分 - Based on available data , the study on regional structure , sedimentary reservoir and source rock characteristics shows that the basins in south china sea had experienced sedimentary evolution in faulting period and depression period , deposited thick cenozoic formation , upwardly developed alluvial fan facies , river - lake facies coastal swamp facies coastal facies , neritic facies and bathyal deposit system , regionally had 3 source rocks of eocene , oligocene and miocene , 3 reservoirs of pre - cenozoic basement buried bill , oligocene sandstone and miocene reef , with pliocene and pleistocene neritic facies and bathyal shale as regional caprock
摘要以现有资料为基础，通过对区域构造、沉积储层、烃源岩特征等基础石油地质条件研究，认为南海海域各盆地经历了断陷期和坳陷期沉积演化，沉积了巨厚的新生代地层，自下而上发育了冲积扇相、河湖相、滨岸沼泽相、滨海相、浅海相、半深海相沉积体系，区域上存在始新统、渐新统和中新统3套烃源岩，前新生代基岩潜山、渐新统砂岩、中新统生物礁3套储层，区域盖层为上新统和更新统浅海半深海相泥岩。 - On the basis of all kinds of stratigraphic and petrologic data of outcrop and well sections , the maps of single factors and sedimentary facies of the paleocene - eocene , oligocene and miocene were compiled with the single factor analysis and multifactor comprehensive mapping method proposed by professor feng zengzhao
摘要根据柴达木盆地北缘露头剖面、钻井剖面的地层学和岩石学研究所取得的各种定量及定性资料，采用冯增昭教授倡导的单因素分析多因素综合作图法，编制了柴达木盆地北缘结绿素红山地区古新统始新统、渐新统和中新统的各种单因素图和沉积相图。
