Data Interpretation Technology for Continuous Measurement Production Profile Logging

摘要

Up till now, there is no production logging data interpretation module in CIFLog, which is the 3rd generation well-logging software platform in China. So the situation has a strong impact on its promotion and utilization. In this paper, firstly, the authors introduce the characteristics of the existing and mature logging interpretation software, and design the data interpretation module functions for continuous measurement production profile logging based on JAVA-NetBeans. Secondly, the calculation methods of apparent fluid velocity, holdup, superficial velocity and flow rate of each phase are presented. Thirdly, eight module functions including wellbore message, curve value, physical parameters, and parameter settings are described. Finally, the authors has analyzed three-phase flow production profile logging data of X well using this module, which includes seven parameters of continuous measurement, and provided the result chart and table. In a word, the practice has proved that the module application effect is good.
