Study on Thickness Interpretation Standard in Oil-Water Transition Zone

The explanation of reservoir thickness in oil-water transition zone has been borrowed from the method of oil layer, And there is a lack of targeted interpretation standards. To find out the development potential of oil-water transition zone and to realize it orderly and efficient exploitation, Research on the interpretation stand needs to be done. This text takes the DLS logging series as the object and utilizes the coring well, MDT and other test information. Through four-property relationship, Reservoir logging response element analysis, etc., The electrical parameters are optimized. Because the oil-water transition section is mostly distributed in Gaotaizi reservoirs, The thickness electrical interpretation standard has been established in the Gaotaizi first, second, third and fourth group including the interlayer deduction standard. The accuracy rate applying the new stand is greater than or equal to 90.6%, solving the problem of low thickness accuracy rate in oil-water transition zone. Technical support is provided for lamination perforation, etc.
