Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings: the online cleaning device for sucker rods and oil pipes includes a liquid accumulation tank 8, and the liquid accumulation tank 8 is connected to the operating wellhead through a flange. The inner bottom of the effusion tank 8 is fixed with a stabbing mechanism main body 2, and the lower end of the stabbing mechanism main body 2 has a liquid outlet 1, and the liquid after stabbing and washing the sucker rod and oil pipe flows into the effusion tank 8 through the liquid outlet 1 The wax scraper 9 is installed on the upper end of the main body 2 of the stabbing and washing mechanism through the gland. The wax scraper 9 is set on the sucker rod or oil pipe, and can be eccentric within a certain range with the swing of the sucker rod or oil pipe. Swing, the wax scraper 9 can clean the liquid on the sucker rod and the oil pipe after stabbing and washing. The main body 2 of t...

Abstract

The invention provides an on-line cleaning device for a sucker rod and an oil tube. The on-line cleaning device comprises a liquid accumulating groove; a stabbing-cleaning mechanism main body is fixedto the bottom in the liquid accumulating groove, a stabbing-cleaning mechanism is mounted on the outer wall of the stabbing-cleaning mechanism main body, and the stabbing-cleaning mechanism is composed of a steam main tube, a steam manifold, steam branch tubes and steam spraying nozzles; the steam main tube communicates with the steam manifold, the steam manifold is axially arranged, the set of steam branch tubes fixedly communicate in the direction perpendicular to the steam manifold, and the every two adjacent steam branch tubes are distributed at equal distances; the steam spraying nozzlesare evenly distributed on the steam branch tubes in the circumferential direction, and the steam spraying nozzles are inclined downwards by 45 degrees and penetrate through the stabbing-cleaning mechanism main body, so that the steam spraying nozzles and the stabbing-cleaning mechanism main body are fixed; the upper and lower adjacent layers of steam spraying nozzles are rotatably staggered by 30degrees in the axial direction of the stabbing-cleaning mechanism main body, and a protective cover is mounted outside the stabbing-cleaning mechanism; and a heat tracing coil is mounted at the bottom of the liquid accumulating groove, a horn mouth is formed in the tail end of the heat tracing coil, and the horn mouth is correspondingly formed in a liquid outlet of the liquid accumulating groove.The on-line cleaning device has the characteristics of being easy to operate, simple, practical, safe and environmentally friendly.

Description

Technical field: [0001] The invention relates to the technical field of oil field pump inspection and well workover operations, in particular to an oil field pump inspection, well workover operation sucker rod and oil pipe online cleaning device. Background technique: [0002] In the field of pump inspection and well workover in oil fields, there will be a lot of crude oil, paraffin and other jelly on the surface of sucker rods and oil pipes lifted from oil and water wells. The traditional method is to lay the pulled out sucker rods and tubing on the rod bridge and pipe bridge built on the ground, and use steam to wash them; or pull the sucker rods and tubing to a special site for cleaning. Doing so will pollute the cleaning site. Invention content: [0003] In order to solve the problems existing in the background technology, the present invention aims to provide an online cleaning device for oil field pump inspection, sucker rod for workover operations, and oil pipe. T...
