In the cause of development of oil field, the produced fluids profile of oil pump well usually adopts through-liquid packer-type to measure the quantity of oil and water reservoir, but the sensitivity of high water response is very low , for the water holdup tool of through-liquid is always limited by ability of capacitance in logging high water well.
在油田的开发过程中,抽油机井的产液剖面一般采用过流式集流方式测试储层的液量和含水情况,但是在高含水井测井中,由于过流式持水率仪器受电容探头性能的限制,对高含水流体响应灵敏度较低。

补充资料:持气率
分子式:
CAS号:
性质:气相占气液两相混合物的体积分率。空塔线速度是影响持气率的主要因素。在有大量液流循环的高液相流速下,持气率比较重要,当液相空塔流速小于3cm/s时,持气率的影响可忽略不计。
