Abstract

Abstract:

In order to improve the accuracy of log interpretation and the applicability of interpretation model for zones, the suitable porosity and saturation models are established for analysis of the 3rd member of Funing Formation in the west slope of Qintong sag, North Jiangsu basin. After the statistics and analysis of the experimental porosity and well logs, it is found that interval transit time after shale correction and the porosity of the experimental analysis can satisfy the relation among acoustic formation factors. The interval transit time for the rock matrix in this area is determined to be 189.39 μs/m, the matrix lithology coefficient（x） is 1.472, and the interpretation model for the porosity in the zone is established. And then, the relation between formation factor（F） and porosity is analyzed. Meanwhile, the variation rule of cementation index（m） with core porosity is determined, that is, with the increase of porosity in mesoporous reservoirs, m is relatively stable, while with the increase of porosity in high-extra-high pore reservoirs, m tends to increase. Therefore, the variable cementation index（m） can be calculated from well logs, and then the oil saturation of reservoir can be calculated accurately. The interpretation results of the established porosity and saturation models in this area agree well with the experimental analysis.

Key words: Qintong sag, logging interpretation, porosity, saturation, complex sandstone, relation among acoustic formation factors
