井下刻度技术在河南油田生产测井解释中的应用

郭海敏等．井下刻度技术在河南油田生产测并解释中的应用测井技术，１９９４，１８（３）：１９５～２０３针对河南油田单井产量低、含水率高、饱和压力低和生产井以抽油机井占优势的特点，提出了一种新的、以井下刻度技术为基础的油水两相流动生产测并解释方法。这种方法适用于由示踪流量计、微波含水率计、温度计、压力计、密度计组成的过环空井下仪器系列。利用全流量层和底水层的产量和测井响应信息，结合由滑脱和漂流模型确定的持水率值，可以得到微波持水率计在所测井的刻度曲线及示踪流量计的环境校正系数，由此可进一步导出反映理论滑脱速度与实际值差异的校正常数。这一方法考虑了单井和区域地层水矿化度变化对仪器响应的影响，在较大程度上消除了微波持水率计存在的非一致性响应现象［１］。文中给出的方法取得了成功的应用，显示出其良好的推广前景。

Application of Downhole Calibration Technology to Production Logging interpretation

A new production log interpretation method aimed at low production rate and high water pumping well is presented in this paper It is suitable to throughannulus production logging tool string consisted of tracer flowmeter, microwave holdup meter, thermometer, manometer and densimeter. According to instrument re.spouse in zero and total flowrate zones, and combining with slip velocity or driftflux model, the calibration curve of microwave holdup meter and environmental correction factors for slip velocity model and tracer flowmeter can be obtained. The inconsistent influence of water salinity on microwave holdup meter response is considered and eliminated in this work. This method has been successfully used in Shuanghe region, Henan Oil Field, showing a good future for practical use.
