摘要
水平井、斜井因其井身倾斜和井筒周围介质分布的非对称性而导致井下流动状态相当复杂,使得水平井、斜井的流型划分、资料解释复杂化。介绍了GHT全井眼持气率仪测量原理和特点,叙述了通过综合常规流体密度仪和GHT持气率仪的测量结果进行水平井流型划分的简单方法,并写出了计算视流体速度和单相流量的公式。
The deviated wellbore and unsymmetric environmental medium of horizontal or deviated well complicate downhole flow regime so that their flow regime identification and logging data interpretation are complicated too. After a brief introduction on principle and features of G-HT Fullbore Gas-Holdup Tool, this paper describes a simple method to distinguish flow regimes in horizontal well by combined data analysis of conventional fluid density tool and GHT, and writes out some formulae on apparent flow velocity and single phase flow rate.
