Research status and prospect of virtual metering of multiphase flow in oil and gas wells
This paper describes the research status and application progress of time-frequency analysis,mechanism simulation,data-driven,mechanism and data-driven fusion in the field of virtual metering of multiphase flow in oil and gas wells.this paper discusses the advantages and limitations of four models of virtual metering of multiphase flow in oil and gas wells,and points out that the depth learning model of virtual metering of oil and gas wells based on physical constraints can obtain a virtual metering model with better generalization ability with fewer samples.With high metering accuracy and fast calculation speed,it has become the research focus and future development trend of virtual metering technology for multi-phase flow in oil and gas wells.
