低渗油藏高阻区注采启动压差计算模型及应用
Calculating Model of the Start - up Pressure Differential in High - resistance Region of a Low - permeability Reservoirs and its Application
摘要
Abstract
Low permeability reservoirs are characteristic of heterogeneity and existence of high resistance region of different shapes and different widths during water flooding development,thus resulting in the increase in permeable flow resistance and the increase in the difficulty of the formation of effective well network. Based on permeable flow theory,a formula calculating start - up pressure drop of injection and production in high resistance region of a low permeability reservoir is derived. The curves of start - up pressure drop of injection and production with permeability,width of high resistance and space between the high resistance and wells are plotted and then the factors affecting start - up pressure drop of injection and production are studied,thus providing theoretic bases for well arrangement of low permeability reservoirs.关键词
