摘要

在理论分析和统计实际生产数据的基础上,得到了聚合物溶液的浓度与聚合物到注入井的距离之间的变化关系,依据这一关系和聚合物溶液幂律指数与浓度之间的关系,得到了确定聚合物溶液幂律指数的表达式,利用该表达式计算出的聚合物溶液浓度幂律指数,应用于聚合物驱试井解释中,与以往利用试凑法确定幂律指数相比,节省了解释时间,提高了解释精度。

Abstract

The relationship of polymer solution concentration and the distance the polymer flowing from the inject well was gained on the basic of theoretics and production data. According to this relationship and the relation between polymer solution power law index and its concentration, a expression of power law fluid index was found out. In the application of well test interpretation, the power law fluid index calculated out from the expression, compared with the power law index trying calculation method before, is more exactitude and quicker.
