Horizontal-wellbore cleanout by rotating jets and annular helical flow hasdeveloped rapidly in past decades, in which the annular helical flow is one ofthe most significant factors to transport the solids in a horizontal wellbore.Because of its complexity and lack of research approaches, the mechanism andcharacteristics of annular helical flow by high-pressure jets were neverrevealed comprehensively. By the computational-fluid-dynamics (CFD) method, theflow field of annular helical flow (such as its generation, continuation, andattenuation) was first manifested. The axial velocity and tangential velocityvary regarding cleaning distance, flow rate, and nozzle assemblies.Furthermore, the dynamic simulation of sandbed sweeping by rotating jets andannular helical flow in a horizontal wellbore was accomplished, and theinfluences on sweeping efficiency were discussed. Finally, the recommendednozzle assembly and its flow-rate distribution in front jets, lateral jets, andrear jets were provided. This study is beneficial in designing the cleaningtool and in optimizing the hydraulic parameters and operation procedures.
