The utility model relates to the field of pipe scraper, which is composed of the upper pipe and the lower pipe successively connected, the upper end of the upper pipe has a joint, the lower end of the upper pipe is connected with the upper end of the lower pipe by screw thread; the upper outer side of the upper pipe is provided with an annular upper baffle, the lower outer side is provided with an annular lower baffle, between the annular upper baffle and the annular lower baffle is provided with a spring sheet, and the outer side of the spring sheet is provided with a steel wire Brush, the side of the upper tube is vertical with spring, the two ends of the spring are welded between the outer wall of the upper tube and the spring sheet respectively; the lower water nozzle of the lower tube is in the form of closing, and the outer wall of the lower tube is provided with spiral blades. The device has simple and reasonable structure, strong practicability and good wax removal effect. The wax scraper can scrape off the wax deposit on the inner wall of the pipe through the conical lower pipe with spiral blades. The steel wire brush of the upper pipe can further clean up the residual wax deposit. The vertical setting of spring piece and spring can help the wax scraper adjust the radial position, make the wax scraper enter the oil pipe vertically, and ensure that all the wax deposit on the inner wall of the pipe is cleaned up.

扶正采油刮蜡器
本技术涉及刮管器领域,特别涉及扶正采油刮蜡器。
技术介绍
随着我国对油田不断的、密集的开采,现在产出的石油含蜡量很高,原油中还含有砂土等杂质,在采油过程中,由于温度和压力的变化,析出的蜡和砂土等会粘附在油管壁上,在不断的积累过程中,蜡层增厚,油管的有效流通通道变窄,内径变小,油井回压增高,产量减少,严重时堵死油管,致使采油作业无法继续进行,影响油井产量。刮蜡是油井工作中的重要环节之一,油管内积累大量蜡时,油管的内径变小,一种尺寸的刮蜡器是无法一次将所有的结蜡通开的,需要反复的更换不同尺寸大小的刮蜡器,过程繁琐,作业时间长;传统的刮蜡器在工作过程中,容易发生偏移,既可能损毁刮蜡器,又导致刮蜡效果不好,油管内壁的蜡不能完全的清理干净。
技术实现思路
针对现有技术的不足,本技术提供一种扶正采油刮蜡器。本技术的扶正采油刮蜡器,是由上管和下管依次连接构成,上管上端有接头,上管的下端与下管的上端螺纹连接;上管的上部外侧设有环形上挡板、下部外侧设有环形下挡板,环形上挡板和环形下挡板之间设有弹簧片,弹簧片的两端分别固定在环形上挡板和环形下挡板上,在弹簧片的外侧设有钢丝刷,上管的侧面垂直设有弹簧,弹簧的两端分别焊接在上管外侧壁和弹簧片之间;下管下部水嘴呈收口状,下管外侧壁设有螺旋叶片。作为本技术的进一步改进,环形上挡板和环形下挡板均固定在上管上,在环形上挡板和环形下挡板之间设有多根弹簧片,多根弹簧片均匀的分布在环形上挡板和环形下挡板之间,每根弹簧片上焊接至少两根弹簧。 ...
