Analysis of Reservoir Four-Properties Relationship and Reservoir Fluid Identification in Daqing X Block

Bailong Wan


The Fuyu oil layer in Daqing area belongs to the low-porosity and low-permeability reservoir, which is characterized by complex lithology, fast phase transition and thin interbred-sandstone. Taking the Fuyu oil layer in Daqing X area as an example, this paper comprehensively applies the drilling, logging and oil testing data, and through the geologic statistics, data fitting and pattern method, and so on, the four-sex relationship of the reservoir is clarified. The reservoir physical property interpretation model and reservoir fluid identification standard are established to provide strong technical support for the remaining oil potential in the study area.
