Application of logging in evaluating carbonate fractured formation in Shuguang low buried-hill zone.

Method Reservoir lithology, fractures, formation production attitude in the target area are studied through logging techniques in combination with core data, oil testing and other information. Purpose To provide basis for evaluating low buried-hill reservoirs in the studied area. Result Lithology discrimination criteria of buried-hilled area are established with the use of natural gamma ray and three porosity data. Production attitude of buried-hill inside formation is initially determined by using variable angle formation dip treatment and single point artificial calculation method. Fracture development section and production attitude of buried-hill formation are recognized through abnormal conductivity detection and well bore ultra-sonic imaging. Interpretation model for reservoir parameters, e.g. porosity, is set up with natural gamma ray, dual laterolog, etc. Conclusion Methods described here are not only feasible and applicable to study Shuguang low buried-hill zone, but provide effective basis for calculating reserve and deciding development plan. ;
