摘　　要：随着油气田开发技术的发展,利用复杂结构井、体积压裂、多元及复杂热力法开采石油时,渗流过程越来越复杂,油井流入动态难以通过统一方程得到。本文提出利用非数值算法的模拟退火算法进行油井流入动态计算,以蒸汽吞吐井为实例,首先分析合理的工作制度,然后把模拟退火算法预测的产量结果与利用数值模拟所得的产量结果进行比较。结果表明,两种方法对比误差非常小,模拟退火算法不需要将单相流和多相流分开讨论,且无任何假设条件,适用范围广,利用该算法研究油井流入动态非常可行。With the development of oil and gas field development technology,the seepage process of complex structure well,volume fracturing,multiple thermal method and complex thermal method is becoming more and more complex,and it is difficult to calculate the oil well inflow performance with unified equation.Aiming at the calculation of oil wells inflow performance,a simulated annealing algorithm based on non numerical algorithm is proposed.Taking the steam stimulation well as an example,the reasonable working system is analyzed firstly,and then the output predicted by simulated annealing algorithm is compared with that by numerical simulation.The results show that the comparison error of the two methods is very small.The simulated annealing algorithm does not need to discuss the single-phase flow and multi-phase flow separately,and there is no hypothesis condition,so it is feasible to use the algorithm to study the oil wells inflow performance.
