The invention relates to a multiphase flow experimental device for a complex inner boundary multi-heat-source lifting shaft. The multiphase flow experimental device comprises a lifting shaft set. The lifting shaft set comprises complex inner boundary lifting shaft pipelines arranged in parallel and a heating lifting shaft pipeline. An inlet of the lifting shaft set communicates with a multiphase fluid input device, and an outlet of the lifting shaft set communicates with a multiphase fluid recovery device. The multiphase flow experimental device for the complex inner boundary multi-heat-source lifting shaft further comprises a control device capable of monitoring and recording the pressure in the complex inner boundary lifting shaft pipelines and the heating lifting shaft pipeline in real time. By means of the device, the problems that in the prior art, multiphase fluid movement in the complex inner boundary lifting shaft cannot be simulated accurately, the simulation experimental temperature does not accord with that of an actual stratum, and pressure measurement is inaccurate are solved, multiphase fluid movement in the complex inner boundary lifting shaft and multiphase fluid movement in the lifting shaft under the condition of increasing temperature by heating are accurately simulated, and the purpose of monitoring the pressure distribution and flow pattern in the lifting shaft in real time is realized.
Description
technical field [0001] The invention relates to the technical field of multiphase pipe flow experiments, in particular to an experimental device for lifting wellbore multiphase flow with complex inner boundaries and multiple heat sources. Background technique [0002] With the continuous increase of the total amount of oil produced, the pressure of the reservoir is decreasing; in the oilfield developed by water injection, the percentage of water produced by the oil well gradually increases, which increases the proportion of the fluid. In order to increase production, it is necessary to adopt artificial lift oil recovery (also known as mechanical oil recovery), that is, to artificially add energy to the bottom of the oil well and lift the oil in the reservoir to the wellhead. The main methods, especially in the late stage of oilfield development, are mainly two methods of artificial lift oil recovery: pumping oil recovery method and gas lift oil recovery method.
