The Study Of Logging Evaluation Technology Of Shale Gas Reservoirs

Evaluation of mud shale oil and gas logging interpretation is shale oil and gas in our country one of the main technical bottleneck of the development of large-scale business.This paper aimed at the shale oil and gas reservoir,Methods through summarizing domestic and foreign advanced technology,Combined with logging data to establish a set of evaluation method of mud shale oil and gas reservoir,Promoted the mud shale oil and gas resources development in our country.Aimed at the difficulties in the evaluation of the shale,Using logging data,core analysis data,Combined with the geochemical data,Carry out: Study on the relationship between the mud shale "six",Mud shale mineral component is studied,calculation method and content of mud shale organic carbon content(TOC)geochemical parameter calculation methods,such as research,mud shale porosity calculation method of parameters,such as research,air content model research,rock mechanics analysis,etc.;Formed a set of suitable for reservoir logging evaluation method of the shale,achieved good effect in practical application.Innovative neutron porosity and density was put forward,M,N,P parameters,in order to establish reservoir parameter model lays the foundation of the shale,logging properties parameters of extraction all adopt the normalized;Put forward a new model of porosity,fully considering the influence of the organic matter of the shale,applicable to the comparison of the shale.Put forward using the minus nuclear magnetic density porosity and effective porosity method to calculate the organic carbon content,in the strata containing phosphate can avoid uranium curve is used to calculate the organic carbon content on the high side.
