Abstract: Because of special characteristics of petroleum geolo- gy in Liyuan anticline,hydrocarbon shows interpretation and evaluation becomes very difficult.Based on the analy- sis of logging presentation and electricity,classification criterion for logging abnormal show zone,and methods of hydrocarbon shows interpretation and evaluation such as logging curve shape method and interpretation chart meth- od have been provided in this paper.Besides that,with geophysical logging techniques,a preliminary discussion on basic methods of reservoir evaluation has been carried out.
