摘　　要：在常规水力参数设计理论的基础上,分析大位移井水力参数设计的特殊性;结合大位移井特点,比较现有三种理论最小排量计算方法,介绍最优排量范围的确定方法;依据循环压耗计算原理,分析大位移井循环压耗精确计算影响因素法。最后总结大位移井水力参数设计方法。Based on regular method and characteristics of ERD Well,the distinction of hydraulics design of ERD Well is analyzed in this paper.Combined with the actual situation,three traditional theoretical minimum flow rate calculation methods are discussed in the paper.And it introduces practical optimization method to determine the displacement range.On the basis of the above,the hydraulics design of ERD well is developed and the step of calculation is summarized.The result shows that the new method is more suitable for practice and thus could provide guidance in engineering design.
