It is showed that the negative pressure increased with the lengthening of pipe outlet (ranging from 177 to 227 mm), and the siphonage and washing effect were enhanced. The water consumption reduced from 6 L to 5 L and the amount of sewage water decreased, when adjusting the length of pipe outlet to be the best value (227 mm).

结果表明，虹吸管出口段长度为177~227mm时，虹吸过程的负压值随长度增加而升高，虹吸作用随之增强、冲洗性能趋好；长度达227mm时，可使坐便器用水量从6L降至5L，所排污水量随之减少。

Add For small diameter, thin-wall, ERW pipe, an alternative to testing curved specimens is to remove the specimens from the skelp used to make the pipe.

添加小直径，薄壁，ERW钢管，可以替换试验曲线试样来从管制钢板中移除试样来制造管道。

If the steel is not killed with aluminum .the Nitrogen content shall not exceed 0.008. warm rolling steel bands for pipes shall be without defects such as foliation inner blisters, nickel fractures cracks or any other defects which can cause break-down corrosion or porosity of pipe walls. the plate or skelp used for PSL 2 pipe shall not contain any repair welds.

如果钢管不是因为铝化断开的话，其实含氮量不应该超过0.008，用于钢管的热轧钢板应无任何如内部水泡面理、镍断口裂痕及其它可引起腐蚀或使管壁多孔化的瑕疵，用于生产 PSL2钢管的金属板或焊接管坯钢不应含有任何修补焊接的痕迹。

In consideration of the problem of drill pipe bending steering in radial horizontal well drilling, ANSYS software is used to simulate its major influencing factors, such as slideway trajectory curvature, clearance, working pressure, roller shape and position and thickness of drill pipe by establishing a finite element model for the bending steering mechanism.

针对径向水平井钻进中钻杆弯曲转向前进运动困难的问题，通过建立弯曲转向机构仿真有限元模型，对其主要影响因素：滑道轨迹曲率、间隙、工作压力、滚轮形状与位置和钻杆壁厚等用ANSYS软件进行仿真研究。
