RJG-Ⅱ移动多功能单井计量装置应用与效果评价

RJG-Ⅱ mobile multi functional evaluation and effect of single well metering device application

长庆油田三叠系的低产采油井普遍存在着回压大,含气量高的油藏状况,井口回压均在2 MPa左右,气液比可达70%以上,且经常出现气液波动变化和间歇出油情况。采用功图法在线单井测量、罐车泄压标定作业,含水率井口瞬间采样及常规的各种流量仪表等计量测试手段,计量误差大,影响因素多,功能单一,均不能真实反映油井生产时的运行状态。RJG-II移动式多功能单井计量装置规避了现有的各种计量仪器仪表和测试方法的弊端与不足,适应复杂多变的各种工况,现场进行在线实时单井计量、带压标定作业,真实准确多功能地反映油井生产的产液量,含水率、原油产量、伴生气量、气液比、井口压力等诸多生产运行参数,为油田生产的科学管理提供了实时准确可靠地技术保证。

Changqing oilfield Triassic low yield oil wells generally exists in the back pressure,high gas content and reservoir conditions,wellhead back pressure are about 2 MPa,gasliquid ratio can reach more than 70 %,and often appeared in gas-liquid fluctuating and intermittent oil.Using the diagram method for on-line single well measurement,calibration tank pressure relief operation,means of testing moisture wellhead instantaneous sampling and various conventional flow meter measurement,measurement error,influence factors and the function is single,can not reflect the real operation state of the oil well production.RJG-II mobile multifunctional single well metering device to avoid the drawbacks of all kinds of measuring instruments and testing methods and the limitations of the existing conditions,to adapt to a variety of complex,on-line real-time measurement of a single well,pressure calibration work,true and accurate to reflect the multiple function of oil well production production,moisture content,crude oil production and associated gas,gas-liquid ratio,wellhead pressure and many other production operation parameters,provides real-time accurate and reliable technical guarantee for the scientific management of oilfield production.
