摘要
针对为每一个油气生产井安装一个多相流量计的成本高、可靠不高以及可操作性不好的问题,论文提出一种基于过程变量值测量的虚拟计量系统。该系统通过构建模拟扼流器计算油气田的总质量流量,使用PVT模块获取油气比的实际值和ST值,利用多相压降模型对含水率进行评价,并结合总质量流量、气油比和含水率确定油气田多相流中的单相流量。最后通过应用实践证明了该虚拟计量系统的有效性。
In view of the high cost,low reliability and poor operability of installing a multi-phase flow meter for each oil andgas production well,a virtual measurement system based on process variable value measurement is proposed in this paper. The sys-tem calculates the total mass flux of the oil and gas field by constructing a simulated choke,obtains the actual value and the ST val-ue of the oil-gas ratio by using the PVT module,evaluates the water content by using the multiphase pressure drop model,and com-bines the total mass flux,gas-oil ratio Moisture rates determine single-phase flow rates in multiphase flow in oil and gas fields. At last,the effectiveness of the virtual measurement system is proved through the application of practice.
