Multi Phase Measuring Technology Research And Implementation

With the development of offshore oil and gas fields, many new technologies are appliedto the offshore platform, and achieved very good results, including oil and Gas Multiphasemetering device. But because of oil gas water three phase flow, the instability, measurement isdifficult, many institutions are focusing on one aspect, so do not lead to a multiphase flowmetering system can adapt to the accurate measurement of all flow component and the flow ofmultiphase flow. In many oil and gas measurement system, measurement technology in thedomestic offshore oil field in multiphase flow measurement system is widely used ingas-liquid separation. Because of the oil gas water three phase flow as the gas phase andliquid phase, and the separator to two-phase separation, separate metering, which not onlyimproves the measurement accuracy, and the measurement results are not affected by the flowpattern and the phase composition of. But the measurement effect and the separation effect isproportional to, so many institutions will focus on the measurement methods in the researchon the separator. In view of the limited space platforms, offshore oil and gas fielddevelopment of high investment, high risk characteristics, on the separator’s request is alsovery high, such as requiring separator has the advantages of small volume, light weight,simple structure, should be unattended etc.. Its universality is poor, the demands of differentseparation, medium of different often require separator with different sizes, so the cycloneseparator are often not used interchangeably. From the above analysis and summary, necessityof GLCC is optimized, the separator has more widely applicable range is obtained, theoptimization of the recommendations put forward in this paper, the structure of the separator.In the actual design of well group scheme, main theory explains the equipment selection basis,used the GLCC separator optimized numerical simulation.
