多相流分离计量装置在金秋气田致密气的应用

Application of Multiphase Flow Separation Metering Device in Jinqiu Tight Gas Field

摘要: 金秋气田致密气开采过程中，井口气、液计量的准确性直接影响气井生产动态分析等工作，现行气田常用的计量方式为单相计量，该种计量模式存在所需设备数量多、占地面积大、投资较高、建设周期较长等问题。本文分析了多相流分离计量装置的工作原理以及特点，开展了多相流分离计量装置现场对比试验，现场试验结果显示气相测量误差在±5%以内，基本满足金秋气田致密气当前开发阶段的使用需要，并可实现致密气单井地面工艺流程优化简化、快建快投。

Abstract: In the exploitation process of Jinqiu tight gas field, the accuracy of well gas and liquid measurement directly affects the dynamic analysis of gas well production, the current common metering method for gas fields is single-phase metering, which has many problems such as large amount of equipment, large area, high investment and long construction period. This paper analyzes the working principle and characteristics of the multiphase flow separation metering device, and car-ries out field comparative tests of the multiphase flow separation metering device, the field test results show that the measurement error of gas phase is within ±5%, which basically meets the needs of the current development stage of tight gas in Jinqiu Gas field, and can realize the optimi-zation and simplification of surface technological process of tight gas single well, fast construction and quick injection.
