摘　　要：抽油井在修井作业起抽油杆时,抽油杆从井内带出的油会污染井场,为此,研发了抽油杆净油工具。采用0.8～1.2 mm厚的铁皮制作成上部为撸抽油杆的小孔,小孔对应抽油杆直径的尺寸,工具的中部为漏斗状,漏斗的下部开口尺寸略小于油管内径以便回收油污,漏斗的上部作有隔层,以便塞棉纱配合小孔撸抽油杆上的油,从中间一分为二,采用开夹式,两长夹把铆在两半漏斗外侧,用弹簧连接,漏斗两侧做有吊耳以拴软绳在油井的套管闸门上。使用后,可以把抽油杆带出的油撸下后通过漏斗流回油管内,采用开夹式,操作方便。适用于油井修井作业起抽油杆工序中,具有环保作用,简单易行,有很好的应用前景。In the workover operations of pumping wells,the oil carried out from the hole by the rod will pollute the platform. The rod absolute oil tool was developed just for this reason.The 0.8-1.2 mm thick iron sheet was made into the sucker rod hole,which corresponded to the size of rod diameter.The central part of tool is funnel-shaped,whose bottom opening diameter is slightly smaller than that of the tubing for the recovery of oil.The upper part of the funnel is filled with compartment in order to squeeze in cotton.By matching the small hole,the oil on rod can be rubbed out.Using open-clip-on,the tool is divided into two from the middle.The two long folders were riveted in the outside of two funnels and were connected with spring.There are lugs on both sides of funnel to tie soft rope to the gate on the casing of the well.By use of the tool,oil following the rod can reflow in the pipe through the funnel.The operation of opened clip-on makes a convenient use.The tool is suitable in the course of rod lifting in workover operations.It has the benefits of environmental protection,simple operation and possesses a good prospect of application.
