Optimization of Vertical Well Placement by Using a Hybrid Particle Swarm Optimization

摘要

Locating wells is an important step in oil exploitation.This paper proposes a novel approach,which first combines particle swarm optimization,genetic algorithm,and a reservoir simulation evaluation tool to optimize the locations of vertical wells.Simulation results show that the convergence efficiency of our approach outperforms traditional genetic algorithm and overcomes the disadvantage of particle swarm algorithm that would be easily trapped into best-at-local solution so that its optimization result has been significantly improved.
