摘要

As the continuous development of oil fields, the mode of oil field water injection changed from the early general water injection into layered water injection, subdividing series of strata gradually stratified water flooding of water injection until now. After subdividing water injection measures, as an intuitive depicting its single well water injection measures segment before and after the contrast of injection profile, introduces the concept of Lorenz curve in the segmentation evaluation before and after water injection. The living cells-recognition lens the degree of curvature of curve and the use of Lorentz curve has calculated the Gini coefficient can be clearly more subdivided the uniformity of injection profile before and after water injection. At the same time using the cumulative injection profile producing extent, bibulous ply calculated from the profile degree of uniformity, use two ways to evaluate the injection profile. Because of the influence of the longitudinal heterogeneity reservoir, its reservoir features are different. Statistical evaluation data, in combination with the practical situation of reservoir geological analysis of the reservoir itself subdivided injection line, using fine hierarchical way to dig up the potential of reservoir water flooding, improve the development effect.
