摘要
Abstract
Fractures and solution pores can greatly improve the physical properties of carbonate reservoirs, therefore, the key factor of reservoir prediction is how to predict the distribution of the fractures and solution pores with geophysical methods. This article proposed a method of fracture and solution pore prediction in carbonate reservoirs based on geo-statistics inversion. Firstly, according to the mineral composition of carbonate rocks, the fracture porosity and secondary porosity were calculated with resistivity curves and three-porosity curves. With the calculated result, geo-statistics inversion was carried out to predict the distribution of the fracture and solution pore. According to the comprehensive analysis of inversion result, the developed area of fractures and solution pores was obtained. This method was applied to the fracture and solution pore prediction in the study area. The predicted distribution characteristics of fractures and solution pores agreed well with the distribution of dolomite, and the veracity of this method was verified.关键词
