Description

An oil-gas-sand multiphase mixed pump experimental system that can automatically adjust medium composition and parameters

Technical Field

The invention relates to an oil-gas-sand multiphase mixed transportation pump experimental system capable of automatically adjusting medium components and parameters, belonging to the field of petroleum transportation experiments.

Background Art

Oil well products in oil fields are mostly mixtures of gas, liquid and solid phases. This multiphase mixture mainly relies on the energy in the oil layer for short-distance transmission. In the modern oil industry, due to the lack of energy in the oil layer during transportation, compressors and pumps are generally used to pressurize and transmit the separated gas and liquid phases separately. However, this method is not only costly, but also has a long transportation cycle and is not intelligent enough.

The oil, gas and sand multiphase mixed transportation pump can transport the mixture of gas, liquid and solid in an integrated manner, saving separation costs and transportation time. However, the existing oil, gas and sand multiphase mixed transportation pump is usually used under general working conditions, which results in it not being able to achieve the highest efficiency when working. Therefore, it is necessary to design an experimental system to optimize the performance of the oil, gas and sand multiphase mixed transportation pump so that it can achieve the highest efficiency under the working conditions of different medium components and parameters. However, the cost of conducting experiments based on the actual situation at the transportation site is too high, and most of the existing experimental systems only conduct experiments on a single parameter without changing the medium composition, and the various devices in the experiment cannot provide timely feedback and adjust the working parameters, which results in the experiment not being able to efficiently optimize the oil, gas and sand multiphase mixed transportation pump in a targeted manner.

Based on the above problems, an oil-gas-sand multiphase mixed transportation pump experimental system which can automatically adjust the medium composition and parameters is designed. Compared with the actual transportation system, the experimental system has lower manufacturing cost and is more convenient to use. At the same time, it can simulate the medium composition and parameters with the required working conditions to optimize the oil-gas-sand multiphase mixed transportation pump in a targeted manner. In addition, the experimenters can collect real-time information and adjust the working parameters of each experimental device in the experimental system through the console.
