Logging interpretation methods and classification evaluation of geological parameters for shale oil reservoirs in the Qingshankou Formation,Central Daqing Placanticline
摘要
Abstract
The geological parameters of shale reservoirs are crucial indicators for the exploration and de-velopment of shale oil reservoirs.Taking the muddy shale layers of the Qingshankou Formation in the Daqing Placanticline as the research object,this study utilized data from logging,core analysis,and tes-ting,adopted methods such as logging curve response characteristics and mathematical statistical analy-sis,established a logging interpretation model for the Qingshankou Formation in the Daqing Placanti-cline,and conducted classified evaluation of the geological parameters of shale oil layers.The results show that:the lithology,physical properties,oil-bearing property,and source rock characteristics of the shale oil reservoirs in the Qingshankou Formation in the central part of the placanticline,calculated and interpreted using the logging interpretation model,have good accuracy when compared with core a-nalysis data.For the reservoirs of the Qingshankou Formation in the placanticline,the content of clay minerals is relatively high(mainly ranging from 35.0％to 50.6％),the effective porosity is high(mainly ranging from 7.0％to 11.0％),while the total organic carbon mass fraction is high(mainly ranging from 1.0％to 3.0％),and the free hydrocarbon content(mainly ranging from 0.2 to 3.0 mg·g-1)and maturity(ranging from 0.53％to 0.94％)are relatively low.Class Ⅱ and Class Ⅲ oil layers are devel-oped in the shale of member 1 of the Qingshankou Formation.Specifically,Class Ⅱ oil layers are dis-tributed in the northwest and east of the study area,while Class Ⅲ oil layers are distributed in the cen-tral part and south of the study area.For members 2 and 3 of the Qingshankou Formation,only Class Ⅲ oil layers are developed,which are distributed in the northwest and southeast of the study area.These results can provide a reference for the exploration and development of shale oil in the Qingshank-ou Formation in the central part of the Daqing Placanticline.关键词
