调剖堵水处理半径及处理液用量计算方法

Calculation Method of Treatment Radius and Treatment Liquid Account about Profile Control and Water Shutoff

针对非均质多油层油田在注水开发过程中，注水井吸水剖面或采油井产液剖面的不均匀性，从调剖堵水前后地层流体渗流特性的变化出发，提出了一种数学方法，用来计算调剖堵水时的处理半径以及最佳处理液用量和添加剂浓度。矿场实例计算表明，该方法对矿场调剖堵水处理具有较大的指导意义。

According to the change of percolation characteristic of formation fluid,the paper gives a mathematical method to calculate treatment radius,optimum account of treatment liquid and concentration of additive. This method is aimed at the non-uniform property of injectivity profile in water injection well or fluid production profile on oil well,as in the water course of water flooding development of non-uniform multi-oil bearing oilfield. The calculation of field example shows that this method has fairly good directive function to the profile control and water shutoff in field.
