Generation method and device of digital twin model based on beam-pumping unit

Abstract

The invention provides a method and a device for generating a digital twinning model based on a beam-pumping unit. The method for generating the digital twinning model based on the beam-pumping unit comprises the following steps of: generating a mechanical three-dimensional model of the beam-pumping unit according to a station yard, a mechanical structure of the beam-pumping unit and a relative motion relationship among components of the beam-pumping unit; generating a multiphase flow motion model of the beam-type pumping unit according to the flow field distribution of the oil-gas mixture in the beam-type pumping unit; and generating a digital twin model of the beam-pumping unit according to the mechanical three-dimensional model and the multiphase flow motion model. According to the invention, the operation parameters of the beam-pumping unit are simulated by establishing the simulation model of the beam-pumping unit process system and are combined with the operation data of the entity device, so that the oil and gas production operation state can be monitored and diagnosed in real time.

Description

technical field [0001] The invention relates to the field of oil and gas field development, in particular to a method and a device for generating a digital twin model based on a beam pumping unit. Background technique [0002] In the prior art, the informatization of oil and gas production in oilfields mainly focuses on data acquisition and visualization, while ignoring the production process and production management itself, especially the lack of simulation of the entire production process of beam pumping units, and the lack of analysis of the collected data. To optimize the production process, it is urgent to establish a digital model of the oil and gas production physical simulation and verification system to realize the digital twin of software simulation and physical simulation, and to transplant the research function of physical model to the level of software simulation. A variety of conditions in the above requirements to expand the scope and capabilities of the stud...
