Abstract

The invention discloses a simulation test method and a simulation test system of a heavy oil conveying screw pump. The simulation test method comprises the steps that input experiment parameters and experiment data are received; a virtual motor model and a motor variable-frequency control running model are established according to the experiment parameters, the parameters of a heavy oil gathering-transporting running environment are obtained and a screw pump working efficiency computing model is established; a virtual running environment of the heavy oil conveying screw pump is established according to the virtual motor model, the motor variable-frequency control running model, the parameters of the heavy oil gathering-transporting running environment and the screw pump working efficiency calculating model; and the experiment data are run under the virtual running environment of the screw pump, and an experiment data is output. The simulation test method and the simulation test system have the advantages that by utilizing a computer software technology, the virtual running environment of the heavy oil conveying screw pump is simulated with the help of externally input screw pump working parameters and the established working model, thereby realizing real-object-detached test and management of the performance of the heavy oil conveying screw pump in heavy oil conveying engineering.

Description

technical field [0001] The invention relates to the field of computer technology, and more specifically, to a simulation test method and system for a screw pump for transporting heavy oil. Background technique [0002] At present, the physical properties of heavy oil in various oilfields at home and abroad are different, and the transportation is mainly carried out by screw pumps. In order to test the delivery performance of the screw pump in the delivery of specific heavy oil, the experimental methods used mainly include the following two types: [0003] One is to complete the test by the screw pump manufacturer. At present, the larger screw pump manufacturers have built screw pump performance test benches, which can complete the performance tests of the screw pump structure, material properties, and conveying characteristics. However, due to the experimental cost and equipment limitations, the manufacturer’s experimental transmission medium mainly uses clean water and or...
