Logging Interpretation Method Of Carbonate Reservoirs

This article mainly researched carbonatite reservoir of particular area, combining withfracture-pore carbonatite logging data of other oilfields. According to analysising actuallogging data, we researched basic parameters’ computational method of this area,quantitative description of pore distribution characteristics, identification of fluidproperties, and formed quantitative calculation for composition and content of rockmatrix basing on porosity curve after shale correction and combining with photoelectriccross-section index curve. We also researched dynamic calculation method of rock matrixparameters, porosity and permeability. Through application of calculation results ofimaging logging data, we calibrated the conventional calculation secondary porosity.Through application of imaging logging data, we establish the quantitative evaluationmethod of pore heterogeneity. Basing on digital core analysis technique, we set up dualpore saturation model. According to researching porous carbonatite reservoir of aimoilfield and fracture-pore carbonatite reservoir of other oilfields, we set up identificationchart of fluid property, the coincidence rate of which reached92%, and established therecognition standard of reservior’s availability.
