介绍一种^(131)I示踪流速测井新方法

Introduction to A New Method for Flow Velocity Survey with Isotope Tracer ^(131)I,

常规的同位素示踪法确定流体平均速度是采用公式V=D/t,该公式只是流体向上匀速运动时才成立,就有杆抽油机排液而言,因排液是间歇式的,所以不宜用常规的方法进行处理,过去获取的测井数据也充分证明了这一点,本文介绍的新方法可以及时发现Ⅰ并准确地确定平均速度。

In conventional isotope tracer logging, mean flow velocity is determined by formula V =D/t, which is valid only when the flow is in upward uniform motion. It does not adapt for piston-robs pumping because output of fluid is intermittent. This is proved by the previous logs. The proposed new method-permits accurate determination of I and mean flow velocity.
