Research Of Measurement Method Of Oil-water And Gas Multiphase Flow

On-line measurement of multiphase flow of the oil, gas and water mixture is significantlyvaluable to the exploitation of oil fields, especially located on the sea or far from the city. But itis very difficult to develop multiphase flowmeters due to the complexity of flow regimes andinconstancy of flow composition at flowing conditions, thus far there are few practicablemultiphase flowmeters available.The research aim of paper realizes a viable method of measuring the flux and each of thecontaining of the multiphase flow. The equipment measuring the multiphase flow based themethod has many excellence, such as the small volume, the expand measuring range andno-radioactivity and so on. The paper develops of the pertinence research based research of thecharacteristic of multiphase flow. The paper has five chapters:The first chapter is introduction. It introduces the aim, meaning and primary contain ofresearch;further more it introduces the actuality and developing current of the multiphase flowoverseas;analyzed the character of the multiphase flow and the the major parameters ofmeasuring multiphase flow. Expectation the demand of measuring multiphase flow.The second chapter is the plan of measurement. It introduces the method of measuring theparameter of the multiphase flow, the familiar the equipment measuring the multiphase flow,analyzed contrastively the plan based corrrlation measurement and nondisjunction and basedgas- liquid adaptive cylindrical cyclone, the paper chooses the last one for the research plan.The third chapter is design of hardware of the equipment measuring the multiphase flow. Itintroduces the compose of hardware of the equipment measuring the multiphase flow, theprimary measuring module.The fourth chapter is the theory and application of the technology based on data fusion. Itintroduces the concept of data fusion, the process of the data fusion in the aim identification, theconfiguration of the aim identification of multiple sensor, the method of data fusion and theapplication on the flow regime identification of the fuzzy integral.The fifth chapter is test. It introduces the character test in room .The summarization is that sum up of the total paper.
