The Study of Production Decline Curve Based on Particle Swarm Optimization

Decline curve is widely used in long term oil production forecast and recoverable reserves calculation. Oil field production decline analysis research is an important parts of oil field dynamic analysis. This paper analyzed and solved the production decline model, based on the high efficiency and high-speed of particle swarm algorithm, and combining the actual production of oil field, taking practical production time correction, computer automatic regression, and other means to making the calculation process more convenient, calculation results more realistic. Contrast experiment shows that the algorithm in this paper have high precision, small error, reliable result, can effectively applied to the production prediction in declining stage.
