摘　　要：泥浆举升离心泵作为无隔水管泥浆循环钻井的核心功能单元,作用是驱动储存在吸入模块中的泥浆携带岩屑沿上返管线回流至钻井平台。以往的无隔水管泥浆循环系统以圆盘泵作为举升单元,围绕圆盘泵做了具体的结构设计和理论分析,对于水力性能更好的多级离心泵研究较少。以多级离心泵作为研究对象,介绍其设计的理论依据及具体的参数,采用CFD-DEM耦合计算的方法构建离心泵的计算模型,进行了全尺度流场模拟,对离心泵的叶轮设计、流场和内颗粒分布规律、泥浆携岩运移规律进行了探讨。计算结果验证了离心泵在设计工况下具有较好的颗粒通过性。基于泥浆举升试验台,对离心泵样机进行了水力性能试验,测试结果表明该泵具有较好的工作特性,其水力性能达到设计要求,可以应用于深海无隔水管钻井作业。As the core functional unit of riserless mud recovery system,the mud lifting centrifugal pump drives the mud stored in the suction module to carry rock cuttings recirculate back to the drilling platform through the return pipeline.Previous designs of the riserless mud recovery system primarily employed disc pumps as the lifting unit,with specific structural design and theoretical analysis conducted around them.However,there has been limited research on multi⁃stage centrifugal pumps,which offer superior hydraulic performance.In this study,we focus on the theoretical basis and specific parameters of a multi⁃stage centrifugal pump,and develop a computational model using CFD-DEM coupling calculation to conduct a full⁃scale flow field simulation.This simulation investigates the impeller design,flow field characteristics,internal particle distribution patterns,and mud rock transport patterns within the pump.The results validate the centrifugal pump’s good particle permeability under design conditions.Furthermore,we conducted hydraulic performance tests on a centrifugal pump prototype using a mud lifting test bench.The test resultsindicate that the pump exhibits satisfactory operational working characteristics and hydraulic performance,meeting the design requirements for application in deep⁃sea riserless drilling operations.
