注采试井双对数理论图版

THE TYPICAL CURVE OF INJECTION-PRODUCTION WELL TEST

注采试井分析以多井渗流力学理论为基础 ,求解注采井地下渗流的精确解 ,研究注水井与生产井之间的关系 ,用注采比、注采井距、注采污染系数比、注采窜流系数比等参数刻画注、采井间关系。在理论上进一步完善地下渗流力学理论 ,从单井的参数分析发展到井间关系分析 ,因此也从研究内容上补充了现代试井分析。在建立无穷大地层油水两相双重介质续流污染的注采无量纲模型基础上 ,对注采无量纲模型求精确解 ,将其数值反演求实空间解 ,制作出注采试井双对数理论图版。

Based on the percolation theory and injection-production well test,the relation between injection well and production well by means of production well test analysis was studied.In fact,injection-production well test is not single well parameter interpretation but multiple one.It not only perfects the percolation theory but also supplement modern well test.First,the paper proposed the dimensionless model of injection-production well test for the infinity double media strata with both oil and water.Then,the solution of the dimensionless model of injection well and production well was obtained respectively.Finally the precise solution of dimensionless model of well test was solved.
