摘要： 井位的部署直接关系到煤层气开发的采气速度及经济效益。基于粒子群算法的劣势和模拟退火算法的优势，提出了一种混合粒子群算法，其以净现值为目标函数，单井控制面积和井位为变量，结合油藏数值模拟方法，优选出净现值最大的单井控制面积和井位，并利用matlab编程来实现。结果显示，基于混合粒子群算法的井位优化方法能够快速确定最优井位，计算量较穷举法大幅度降低；沁水盆地煤层气田的最优单井控制面积为0.2 km2；对于最优单井控制面积，混合粒子群算法得到的最优净现值比常规矩形井网的净现值增加12.55%；最优井位分布与含气量、渗透率密切相关，其中渗透率的影响尤为重要，最优井位是含气量与渗透率的最优组合。该研究成果为煤层气开发井位优化提供了新方法。

Abstract: The well locations directly influence the gas recovery factor and the economic benefit of coalbed methane development projects. Based on the disadvantage of particle swarm optimization and the advantage of simulated anneal algorithm,a hybrid particle swarm optimization algorithm was proposed. This algorithm took the net present value as the objective function,the single well control area and well location as variables,and combined the reservoir numerical simulation method to optimize the single well control area and well location with the largest net present value(NPV),which was realized by matlab programming. The results show that the well location optimization based on hybrid particle swarm optimization algorithm overcomes the disadvantage of the conventional well pattern which is experience-dependent. It needs less amount of computation to determine the optimal well location compared with exhaust algorithm. The optimal single well control area of coalbed gas field in Qinshui Basin is 0.2 km2. For the optimal control area of a single well,the optimal NPV obtained by hybrid particle swarm optimization algorithm is 12.55% higher than that of the conventional rectangular well pattern. The optimal well location is closely related to gas content and permeability,among which the permeability distribution is particularly important,and it is an optimal combination of gas content and permeability. The research results provide a new method for the well location optimization of CBM development.

Key words: coalbed methane, well location optimization, single well control area, hybrid particle swarm optimization algorithm, numerical simulation, Qinshui Basin
