| Abstract: |
| The pumping well of the annular oil collecting ring, and the oil gathering pipe network are taken to analyze. Based on the multiphase flow model in the horizontal tube, in combination with the simulation technology on the dynamic parameters of the pumping, the simulation model on the relationship among the pressure drop in the oil gathering pipe network, the wellhead pressure of the pumping well and the watered parameters in the oil gathering system is built. Then another simulation model on the relationship among the input power of pumping wells, oil production and wellhead pressure is also given. Taking the lowest energy consumption and the biggest system benefit as the objective function for optimization, a mathematical model on the watered parameters optimization in the oil gathering system is presented. The results show that the inlet oil pressure has a significant effect on the input power and well production, and the water temperature and flow have great influences on the total energy consumption and system benefit. The overall optimization on the machine mining and oil gathering system can significantly improve the overall economic benefit of the system. |
