flushed zone

A preliminary discussion is made on surface charge distribution on the borehole wall and volume charge distribution in the flushed zone in a borehole by using the theoretical results.

应用所得理论结果，对裸眼井井壁的面电荷分布和地层冲洗带内的体电荷分布情况作了初步的探讨。

in simple models, the invaded zone and the flushed zone are considered synonymous.

在一些模型中，常认为侵入带就是冲洗带。

the parameter model corresponding to the new invasion profile model not only comprises flushed zone conductivity, undisturbed zone conductivity and transition zone radius, but also comprises an index n which reflects the transition zone's change pattern.

而与含有过渡带的新侵入剖面模型相对应的参数模型除包括冲洗带电导率、原状地层电导率和过渡带中点半径外，还有一个反映过渡带电导率变化的指数N。
