摘要
试井分析的关键在于确定压力的变化特征。文章针对产量呈多項式变化的情形,给出了无限大均质地层中压力分布的精确解。应用该精确解可计算油层重要参数——表皮系数。
Usually, oil and gas wells are producing at a variable rate in the course of oilfield development. Considering that a key problem of well testing analysis is to determine the characteristic of pressure variation, an exact solution for pressure distribution in an infinite formation is presented which is expressed in the form of multinomial. The exact solution is used in calculating skin factor, one of formation parameters.
