Logging Evaluation And Heterogeneity Study Of Saetru Reservoirs In X Oilfield

In this paper, the fine reservoir description technology was mainlyapplied to further understanding of the characteristics of the geology ofSaertu reservoirs in X oilfield. Mainly using drilling data,on the basis ofhigh-resolution stratigraphic correlation,to study the oil reservoir or sandbody. Micro structure control on development unit was established. Thelogging curves, core analysis, testing for oil and production performancedata were applied to the study of sedimentary microfacies and changerule of oil reservoir physical properties. Based on core analysis andapplying of logging to study the relationship of four properties，then buildthe logging interpretation model and evaluate of single well logging,it canimprove the reliability of logging evaluation. Established evaluationstandard of the reservoir through multiple well logging evaluation. Thereservoir heterogeneity and the flow unit were also studied. Theheterogeneity of reservoir distribution has carried out research, obtainedthe heterogeneity distribution characteristicsFrom single-well lithology, reservoir property,oil bearing and connectingrelations of sand body between wells, from the reservoir physicalproperties to the connecting relation, from the smallest unit to single sandbody, from the Angle of the sedimentary microfacies to analysis each unit of oil and gas reservoir, the comprehensive study results aboveprovides the basisfor building static geological model of a moresystematic and comprehensive Saertu reservoirs in X oilfield.
