Computer Simulation of Crude Oil Extraction Using a Sucker Rod Pumping Unit in the Oil Well–Resevoir System
- 1 Downloads
The process of operating volatile oil wells using the sucker rod pumping method is considered. An algorithm is developed to determine the main characteristics of the development of deposits in the oil well–reservoir system and the parameters of sucker rod pumping unit. The real thermodynamic properties of volatile oil and the compressibility of the reservoir are taken into consideration. Based on the proposed algorithm, a computer model of the oil well operating process by a sucker rod pump is developed. This model makes it possible to monitor the main operating parameters of the pump and the characteristics of the reservoir system. The development of the reservoir and the effect of the pump operating parameters on its productivity are studied using the developed simulator. The influence of pumping rate on the pump performance is established to be insignificant if a certain value is exceeded. The proposed algorithm can be used to create intelligent systems for automated control of sucker rod pumps in the well–reservoir system.
