连续测量全井眼过环空产出剖面测井仪

介绍了连续测量全井眼过环空产出剖面测井仪器的结构和工作原理，并对其在室内实验及现场测井资料进行了分析。仪器由全井眼持水率传感器、集流型涡轮流量计和集流扶正器构成。持水率传感器由测量、校正两部分构成。传感器最终输出仅由油水两相流持水率决定，实现了持水率的全井眼测量。仪器配接了1个带有扶正器的集流器，在实现连续测量扶正的同时，进行半集流方式的流量测量。现场测井时，流量和含水率测量值均采用随不同深度连续测量方式。所测流量的曲线可直观反映出井内各产层的产液情况，连续持水率曲线可以直观反映出各产层的持水率变化情况，结合井口化验结果就可以对1口井的各层位的产水和产油情况作基本判断，提供直观的解释结果。

Through Annular Space Continuous Full Borehole Production Profile Logging Tool

The configuration and principles of Through Annular Space Continuous Full Borehole Production Profile Logging Tool are introduced herein. The experiment results and logging data are also analyzed. This tool consists of a water holdup sensor, a collection flowmeter and a centralizer. The water holdup sensor has two parts, measuring part and correcting part. Output data only depends on the water holdup of oil/water two-phase. Measuring water holdup in the full borehole is realized. One centralizer with the collector in the tool can make continuous measurements and semi-collecting liquid flow measurements in the same time. Measuring results of flow and water holdup adopt continuous measuring modes with different depths in the logging field. According to flowrate and water holdup data, production power and water holdup variety of every formation can be obtained directly. Through comparing the measured results and the chemical examined liquid sample, obtained is the visual producing water or oil in a well.
