机械采油方式优选的模糊评价法

The Fuzzy Evaluation of the Optimization of the Patterns of Artificial Lift

将机械采油方式的选择视为模糊评价问题,建立了抽油机、潜油电泵、螺杆泵采油方式优选模糊评价数学模型,即采油方式优选目标函数;并给出了通过该数学模型实现由计算出的目标函数值大小来优化最优采油方式的方法。以大庆油田潜油电泵井X8-4-28为例,应用上述方法对该井进行了采油方式的优选。优选结果表明,使用该方法优选出的采油方式与该井通过实际经验选择的采油方式一致。

Regarding the choosing patterns of artificial lift as the problem of fuzzy evaluation,the mathematical models of fuzzy evaluation which is the objective function of the optimization of the patterns of artificial lift,which can be available to the optimization of the artificial lift patterns of pumping jack,submersible pump and screw pump,are established,and the method of the optimization of the patterns of artificial lift by using the magnitude of the values of the objective function is given.Taking the submersible pump well X8-4-28 in Daqing Oilfield as an example,the optimization of the patterns of artificial lift using the method mentioned above is conducted.The optimized results show that the artificial lift pattern optimized using the method given in this paper is in accord with that chosen through practical experiences.
