Chen Yong chang.Development and Application of High Sensitive Water Holdup Meter.WLT,1993; 17(2):141～147 Water holdup is an important parameter for determining type of fluids(oil,gas or water) produced from the zone of interest.But the sensitivity of water holdup meter decreases in high watercut formation.In order to solve this problem long existing in production log,a high sensitive water holdup meter has been de- veloped,whose measuring range is 0～1.Its theory,design concept and field test results are given in this paper.Logs have been run in thirty wells and comparison is made between logging data obtained from new water holdup meter and fluid identification device.All this proves the success of the development of this tool.It will play an important role in oil field development.
