尽管各种气举优化算法已经在许多著作中提出,但适合长期油藏开发研究的算法还廖廖无几。油藏的长期开发研究需要高效、灵活的气举优化过程,并且能够有效地处理复杂流体的各种流态和操作约束。这些算法也必须是迅速收敛的。本文介绍的气举优化问题是通过选择最理想的气举产量和气举速度来确定最大的日产量。气举速度取决于地面管网的速度和压力约束以及可能的举升气量。
Although a variety of gas lift optimization algorithms have been proposed in many books, algorithms suitable for long-term reservoir development and research are still scarce. Long-term development of reservoirs requires efficient and flexible gas lift optimization process, and can effectively deal with various fluid flow and operational constraints of complex fluids. These algorithms must also converge quickly. The gas lift optimization problem presented in this article is to determine the maximum daily output by choosing the best gas lift and gas lift speed. The rate of gas lift depends on the speed and pressure constraints of the surface network and possible lift gas.
