Abstract
Based on the favorable lithofacies assemblage characteristics and genesis analysis,this paper analyzes the accumulation characteristics of member Sha-1 of the key shale oil block in Bonan region,and analyzes the accumulation characteristics of member Sha-1 of the Bonan sag by means of GRP sequence division method,GR spectrum analysis and rock electrical characteristics analysis of coring wells,and analyzes the accumulation of member Sha-1 of the Bonan sag by combining the results of X-ray diffraction analysis of the whole rock,and analyzes the argillaceous content of the lithofacies characteristics.It is believed that the pores of the reservoir of mudstone or shale mainly develop primary pores,secondary pores(dissolution pores)and organic matter pores,and the crack types are mainly structural joints,lamination joints and clay mineral shrinkage joints,and the microporous amount is less,and the mesoporous is predominant.The laminar mica-argillaceous shale facies with a moderate content of organic matter is a good reservoir face.the organic-rich laminar aragonite shale facies and organic-rich laminar limestone shale facies are the facies with good oil-bearing and movability.It provides a certain basis for the exploitation of continental shale oil in the Bonan sag.关键词
