中文摘要：

在在水平井存在的问题的看法，例如沙扔并且清洗地上凿穿的困难，有对这些问题的分辨率合适的旋转喷气的一种技术被介绍。把二阶段的流动理论，沙运动法律上的分析和打漩的地基于液体固体有影响的因素被进行。结果显示出那：1 ) 与在水平节体环增加排水量，打漩的地力量增加，并且当排水量是不变的时，越从嘴靠近，打漩的地力量是越多 stronger；2 ) 头旋转速度和液体粘性几乎没由在某个范围增加液体粘性在打漩的地力量，而是液体罐头增加的带沙的率上有小影响；3 ) 旋转绳并且在体环减少它的怪癖为在体环的沙移植是导致的；4 ) 沙能再被推迟并且加速并且打漩的地力量被螺旋煽动者提高。因此，研究结果为旋转喷气工具的设计和申请提供理论基础。

英文摘要：

In the view of the problems existing in horizontal well, such as sand depositing and cleaning difficulty of borehole, a technology with rotating jet suitable to resolution of the problems was presented. Based on liquid-solid two-phase flow theory, the analyses on the sand movement law and the swirling field influential factors were conducted. Results show that： 1） With the increasing of displacement in horizontal section annulus, swirling field strength increases, and when the displacement is constant, the closer from the nozzle, the stronger the swirling field strength is; 2） Head rotating speed and liquid viscosity have little influence on the swirling field strength, but the sand-carrying rate of fluid can increase by increasing liquid viscosity in a certain range; 3） Rotating the string and reducing its eccentricity in annulus are conducive for sand migration in the annulus; 4） The sand can be suspended and accelerated again and the swirling field strength is enhanced by the helix agitator. Hence, the research results provide the theoretical basis for the design and application of rotating jet tool.
