基于傳質(zhì)擴散理論的高滲油藏竄流通道量化方法
[Abstract]:The cementation of high permeability sandstone reservoir at sea is loose, the effect of injection water scour on reservoir reconstruction is obvious, the channeling channel is "spindle-shaped" on the plane, and the vertical direction has obvious characteristics of "thief layer". At present, the continuous quantization method in time domain and space domain of channeling channel has the defects of too complicated mathematical model and solving process. Considering the plane and vertical characteristics of channeling flow channel, a dimensionality reduction method is established to transform the three-dimensional physical model of channeling flow channel between injection-production wells in high permeability reservoir into the superposition of two two-dimensional physical models of plane and section. According to the similarity between the spindle-shaped distribution of injected water on the plane and the concentration distribution of injected chemicals, and the monotone correlation of water injection multiple, water saturation and permeability change multiple, The concept of "equivalent diffusion coefficient" based on "saturation difference" is proposed, and a plane mathematical model containing water content at output end is established. In view of the fact that the "thief layer" is the main channel of ineffective water circulation, the dilution multiple is defined, the analytical solution of water content at the output end is realized, and a fast quantitative method for the thickness of channeling channel, permeability difference and equivalent diffusion coefficient is established. The application results of field examples show that the thickness of channeling passage is 0.04 m ~ 0.38 m and the permeability difference is 22 ~ 8 m respectively, which is consistent with the tracer interpretation results. The equivalent diffusion coefficient obtained by interpretation also represents the fingering degree of reservoir microcosmic heterogeneity and oil-water viscosity ratio, as well as the size of channeling channel sweep area.
