| Abstract: | Based on the reservoir characteristics of Ch7 in the Zhenyuan area,combined with the data from core analysis,capillary pressure curves and well-logging,the relationship between reservoir parameters and electric responses is studied.The neural network explanation models of multi-composition lithology,porosity,permeability and saturation and the regression analysis model of porous throat structure were established.Furthermore,the effective thickness of reservoirs was determined by the comprehensive method of oil-bearing attitude,reservoir properties and electrical response. |
