Abstract:

There are three sections of strata,their depositional environment is different,there are reservoirs developed in every section with different prosity and permeability,there is different physical property with respect to different lithologies.According to the characteristics of the strata,the lithologies,physical properties,conductivity and oil-bearing properties and the relationship between each other of the reservoir rocks such asconglomerate,sandstone,pebbled sandstone are studied respectively,which places a consolidate foundation for establishing fine interpretation model.On the basis of the four-property,in view of core analysis,the core calibrating log information is taken as the train of thought to set up mud content computation model,porosity interpretaion,odel and permeability model are set up fpr each interval and lithology respectively.According to the characteristics of reservopirs,water saturation computation model is established.The established model possesses high accuracy.The method is of practical meanings for improving fine reservoir log interpretation for Bei 16 area.

Key words: clastic rock, interpretation model, four-property relationship, log interpretation, Junggar Basin
