Description
技术领域：Technical field:
本发明属于计量设备技术领域，涉及一种油气水多相流量的分离型计量设备。The invention belongs to the technical field of metering equipment, and relates to a separate metering device for oil-gas-water multiphase flow.
背景技术：Background technique:
油气水多相流量计是油田开采的原油在向管道中输送时进行油气水三相流量计量的仪表，油水气多相流体的在线计量在油田开采，尤其是海上油田和陆上油田具有特别大的经济价值。传统的计量方法是把油井开采的原油送入三相分离器，通过分离器将原油分成油水气三相，再通过安装在分离器各相出口的流量计对三种流体分别进行计量；但这些传统的气液分离器结构复杂，尺寸较大，成本较高，给设计和制造都增加了很大难度，降低了多相流量计的实用性；采用油水气多相流量合并计量方法可以节省空间、资金且能连续实时计量各油井的产量，并简化流程。目前，油井产量计量室油藏动态分析研究是油田生产管理过程中不可或缺的程序之一，现有的油气水多相流量计的研究工作始于1980年左右，近年来，多相流量计在油井产量计量方面越来越受到各大石油公司的关注，现有技术中多相流量计的有效相含率测量主要依赖放射线技术，而基于伽马射线的测量技术因不受流体相态变化影响、测量部件不与流体接触等优点而被广泛使用，但是该技术在高含气的油水气三相流体的条件下含水率测量精度较差，导致原油计量精度不当，不能完全满足实际需求，且近年来大幅度提高了对放射线的使用监管，不鼓励放射线的使用，致使放射线测量技术在油田上未能继续发展和推广。The oil-gas-water multiphase flowmeter is an instrument for measuring the oil-gas-water three-phase flow when the crude oil exploited in the oilfield is transported to the pipeline. The online measurement of the oil-water-gas multiphase fluid has a particularly large economic value. The traditional metering method is to send the crude oil extracted from the oil well into the three-phase separator, through which the crude oil is divided into three phases of oil, water and gas, and then the three fluids are measured separately through the flowmeter installed at the outlet of each phase of the separator; but these The traditional gas-liquid separator is complex in structure, large in size, and high in cost, which adds great difficulty to design and manufacture, and reduces the practicability of multiphase flowmeters; the combined measurement method of oil-water-gas multiphase flow can save space , funds and can continuously measure the production of each oil well in real time, and simplify the process. At present, the oil reservoir dynamic analysis and research in the oil well production measurement room is one of the indispensable procedures in the oilfield production management process. The existing research work on oil, gas and water multiphase flowmeters began around 1980. In recent years, multiphase flowmeters Oil well production measurement has attracted more and more attention from major oil companies. The effective phase holdup measurement of multiphase flowmeters in the prior art mainly relies on radiation technology, while the measurement technology based on gamma rays is not affected by fluid phase changes. It is widely used because of its influence and the fact that the measurement parts are not in contact with the fluid. However, the measurement accuracy of the water content of this technology is poor under the condition of high gas content oil-water-gas three-phase fluid, which leads to improper measurement accuracy of crude oil and cannot fully meet the actual needs. And in recent years, the supervision on the use of radiation has been greatly improved, and the use of radiation has not been encouraged, resulting in the failure of the development and promotion of radiation measurement technology in oil fields.
