摘要
为了在安全承载条件下提高超短半径水平井导向筛管的弯曲能力,提出了一种导向筛管多参数耦合优化方法。采用拉丁超立方设计方法采样,基于响应面法,建立了以导向筛管危险截面最大等效应力为约束,以导向筛管转过角度最大为目标的优化模型,采用遗传算法寻优,得到了优化后导向筛管的结构尺寸。对优化后的导向筛管进行力学分析,结果表明,优化后的导向筛管弯曲能力提高了33.35%,每米的加工量减少了10%。
For purpose of improving bending capacity of the guide screen pipe in ultra-short radius horizontal wells under safe loading conditions,a multi-parameter coupling optimization method for the guide screen pipe was proposed;meanwhile,based on response surface method and Latin hypercube design method,an optimization model was established,which was constrained by the maximum equivalent stress of the guide screen pipe’s dangerous section and aimed at the maximum rotation angle of the guide screen pipe;in addition,the genetic algorithm was used to optimize structure size of the optimized guide screen.The mechanical analysis of the guide screen optimized shows that,the bending capacity of the guide screen pipe optimized can be increased by 33.35%and the processing capacity per meter decreased by 10%.
