文中根据水平井计算持水率难的特点，提出一套基于CAT测井仪器来计算水平井持水率的新方法；同时，针对CAT生产测井资料提出了一套新的测井解释方法，且对该解释方法进行了验证。结果表明，该方法利用水平井CAT生产测井资料进行产液解释，符合率达到90%以上，具有一定的应用及研究价值。

Based on the difficulty of water holdup calculation for horizontal well, this paper puts forward a new method using CAT logging tool to calculate water holdup of horizontal well. At the same time, aimed at the CAT production logging data, it also puts forward a new set of logging interpretation methods. The interpretation methods are verified, which show that the liquid producing interpretation results for the CAT production logging data of horizontal well by the methods are consistent with the accuracy of more than 90%, having certain application and research value.
