Application of lorentz curve in Shengli oilfield development

By using the lorenz curve to carry out quantitative analysis of heterogeneity and difference of glutenite reservoir daily oil production,and to analyze various development status of fault block reservoir.By using the production index curve,to carry out capacity difference analysis between layers andthe rationality of development series.By using injection profile and production fluid profile curve to carry out quantitative depicts of inhomogeneous degree of a moment of the absorbing water and fluid producing profile,reflecting its change trend with time and the evaluation of control measures of water shutoff.By using the flow curve,to carry out the seepage difference analysis between layers and the evaluation of the formation adaptability.By using the lorenz curve,such as water cut and recovery degree curve to analyze development effect,representingthe uniformity of water flooding
