The evaluation of Heavy oil reservoir is always a difficult problem for exploration,The Four-property relationship of Heavy oil reservoir is poor, and they are point at the deep malmstone reservoir.There is little on the Four-property relationship study on shallow glutenite heavy oil reservoir.This thesis based on the shallow glutenite heavy oil reservoir in Liyuan area,Biyang sag. First,we studied the characteristic of the glutenite reservoir, learn the components of rock,analyse the components of the agglutinate,and study the respect of the electrical property,then carry on the classification and identification of lithology. Second, we study the structure of the hole based on the experiment,analyse the porosity and permeability,resolve the question of the high anisotropism.At the same time,carry on the analyse of anisotropism for classificating the reservoir. Third, analyse the electric anisotropismof the glutenite reservoir, especially the shallow reservoir.Build the well log interpretation model,because of the particle size mixed,complex pore structure,high anisotropy,high shaliness,buried shallowly and low degree of mineralization and then the Archie saturation model is poor. This thesis analyse the the influencing factor of Archie parameter,and determines the Archie parameter for the low-salinity glutenite blocks by the study of core electrical test.This paper analyzes the well logging data, log data,core experiment and well testing data of Liyuan area.It confirms the Four-property relationship of the reservoir in this area. On the basis of the detailed data statistics,this paper established the log interpretation model and fluid identification standard.It formed one better reservoir evaluation technology of heavy oil reservoir in Liyuan areaThis method was applied to the Liyuan shallow strata and achieved good results..Which provides a strong basis for further development of evaluation and increase the reserves and production.
