permeability recovery

The testing results of the permeability recovery have always been serving as a major guideline in evaluating the formation damage.

渗透率恢复值的测定结果作为评价保护油气层技术的主要技术指标,一直指导着现场保护油气层钻井液技术的施工。

Test results show that by adding suitable amount of polyglycol and temporary plugging agent in the foam drilling fluid, the permeability recovery increases from 66.

实验结果表明,泡沫钻井液中加入适量暂堵剂和聚合醇后,渗透率恢复值从66。

与传统方法相比,该方法设计的钻井液可有效封堵同一储层中不同粒径的孔喉,尤其是较大尺寸的孔喉,对储层岩样的侵入深度较浅,可获得更高的岩心渗透率恢复值及更低的突破压力梯度,降低钻井液污染。

Unlike the previously defined permeability, many values of effective permeability now exist, one for each particular condition of fluid saturation.

与上文所定义的渗透率不同，渗透率有许多数值，每一个数值都表示流体饱和的特定条件。

The effective permeability is stated as some numerical value at some given saturate conditions.
