Abstract

Abstract: The favorable target zone of shale oil reservoir is the overlapping area of resource sweet spot,physical property sweet spot and engineering sweet spot.To find out the primary geological parameters that may be applied to characterize the three kinds of sweet spots is the key to identifying favorable shale oil target zones.In the study,we propose a comprehensive quantitative method to identify favorable shale oil target zones based on major geologic parameters.First,the primary geological parameters including free oil content,permeability and Young modulus are chosen to establish a weighting evaluation function.Second,a comprehensive weighting factor is constructed by using the weighting evaluation value of primary geological parameters,to define the distribution of comprehensive weighting factors of the favorable,low-efficiency and ineffective layers in shale oil exploration.Third,the favorable target layers and zones of shale oil is thereby mapped.The method has been successfully applied to evaluate the comprehensive weighting factors of the shale oil sequence in 27 wells in the lower sub-member of the 3rd member (Es^3L) and the upper sub-member of the 4th member (Es^4U) of the Shahejie Formation,Dongying Sag,Bohai Bay Basin,and to map favorable layers and zones for shale oil exploration.The result is of certain referential meaning to the exploration and development of shale oil in the Dongying Sag.

Key words: primary geological parameter, free oil content, permeability, Young modulus, favorable target zone of shale oil, Dongying Sag, Bohai Bay Basin
