东营凹陷下始新统沙四段烃源岩有机相分析
Analysis on Organic Facies of Hydrocarbon Source Rocks of the Forth Member of Shahejie Formation of Lower Eocene in Dongying Sag
摘要
Abstract
With many deep oil and gas reservoirs found around the world,the researches are beginning focusing on generation and accumulation of the deep hydrocarbon resources in recent years.Organic facies can assist to make a better evaluation of hydrocarbon potential of source rocks,and then guide oil and gas exploration.The organic facies of hydrocarbon source rocks of the fourth member of Shahejie Formation of Lower Eocene (Es4) is divided into three types according to the data of sedimentary characteristics,sedimentary environment,organic petrology,organic geochemistry and palynofacies,and by using special element ratios,organic carbon content,vitrinite reflectance and palynofacies model.Three types from the bottom to the top are weak reducing alluvial fan organic facies under salt beds,strong reducing salt lake organic facies within salt beds and reducing deep-half deep lake organic facies upper salt beds.In the three types of organic facies,organic matters in hydrocarbon source rocks upper salt beds are best,with good exploration prospects,and those within salt beds go second,those under salt beds last.关键词
