准确获取井筒中各相持率是生产测井产出剖面精确解释的关键步骤之一,水平管中因普遍存在层流导致常规居中测量的持率仪器响应产生纵向片面性.电容阵列仪是一种采用多探头覆盖全井眼信息采集的新型流体识别技术,研究基于电容阵列仪、放射性流体密度计和电容持水率计的室内模拟试验.分析了水平管油水两相流动型态和电容阵列仪的持率确定方法,详细研究了3种不同持率测量仪器随流体流动型态变化的响应规律,提出了水平管油水两相流持率参数优化选取的方案.

Acquiring accurately the fluid holdup of each phase along wellbore was one of the key steps for production profile interpretation in production logging. Because laminar flow was commonly existed in horizontal pipes, the responses of centralized measuring instruments were notaccurate. Capacitance Array Tool (CAT), which was a new-style fluid i-dentification technology with multi-probes, could acquire fluid message along full wellbore. Based onihe laboratory simulation experiments on CAT, Radioactive Density Meter (RDM) and Capacitive Water Holdup Tool(CWHM) , the flow pattern of oil-water two-phase in horizontal pipes and holdup of CAT determination method are discussed. The response characteristics of CAT, RDM and CWHM changed with different flow patterns are studied in detail, the optimization selection schemes of holdup parameters of oil-water two-phase in horizontal pipes are proposed preliminarily.
