Abstract
The invention provides a thread grease coating device, wherein a gun cover and a housing are covered on an oil way joint, a press cap is connected with the oil way joint, an inner table shoulder of the gun cover is pressed by the right end face of the press cap, the left end face of the housing is pressed by the gun cover, the inner table shoulder of the housing is pressed on an outer table shoulder on the oil way joint, an oil extruding gun is connected with the gun cover, an oil scraping cover is arranged at the outer end of the housing, an inner hole and a through hole are arranged on the oil way joint, the outer end of the oil way joint is provided with a guide head, the guide head of the oil way joint is inserted into an oil pipe when the device is used, the oil scraping cover is sleeved on the outer wall of the oil pipe, so that a hollow cavity is formed between the housing and the oil pipe, a screw thread of the oil pipe is arranged in the hollow cavity, after the oil scraping cover is sleeved on the outer wall of the oil pipe, the hollow cavity can be filled with thread grease by operating the oil extruding gun, when the oil extruding gun is outwards drawn, the oil scraping cover passes through on the screw thread of the oil pipe, and the thread grease is evenly coated on the screw thread of the oil pipe, so that the problem of uneven coating of the thread grease can be overcome, and when the oil pipe is connected with the screw thread and used, the screw thread of the oil pipe cannot be damaged caused by thread gluing and rusting.
Description
Technical field
The invention belongs to the equipment of the on-the-spot usefulness of oil field operation, is a kind of dope application device.
Background technology
Dope will before screwed connection, be smeared with the screwed connection of the root oil pipe G.I.H that gets up in well down during the oil pipe operation in the oil field on the oil pipe pin thread, play a part to protect screw thread to prevent the screw thread thread gluing and get rusty.Be to be stained with dope with brush by manual work to spread upon on the oil pipe pin thread to the method for smearing dope on the oil pipe pin thread at present, it is bigger that this method is influenced by human factor, uneven problem can occur smearing; The screw thread that makes can not get the protection of dope, causes the oil pipe screw thread short service life, and the oil well production cycle is shortened; Oil well needs frequent workover treatment; Increase workover cost, need to change big dipping tube, economic loss is serious.Smear dope by manual work and also make the operating worker work big, inefficiency, job scheduling is slow.
Summary of the invention
The objective of the invention is to design a kind of dope application device, make the oil pipe screw thread evenly smear dope, overcome the problem of above-mentioned existence.
The objective of the invention is to realize like this: comprise crowded oil gun, rifle lid, pressure cap, oil duct joint, shell, scrape oil jacket, rifle lid, outer cover suit are on the oil duct joint, and pressure cap is connected with the oil duct joint; The right side of pressure cap compresses the interior shoulder of rifle lid, and the rifle lid is pushed down the left side of shell, and the interior shoulder of shell is pressed on the outer circular bead surface on the oil duct joint; Rifle lid, pressure cap, oil duct joint, shell are linked into an integrated entity, squeeze oil gun and be connected, scrape the outer end that oil jacket is installed in shell with the rifle lid; Endoporus, linked hole are arranged on the oil duct joint, and there is guide head oil duct joint outer end, and the guide head of oil duct joint inserts in the oil pipe during use; The frizing cover is sleeved on the outer wall of oil pipe; Make between shell and the oil pipe and form cavity, cavity communicates with crowded oil gun inside through endoporus, linked hole, and the screw thread of oil pipe is in the cavity.
Beneficial effect of the present invention is: after the frizing cover was sleeved on the oil-pipe external wall, the crowded oil gun of operation just can make and be full of dope in the cavity, when outwards oil gun is squeezed in drawing again; Scraping oil jacket passes by from the screw thread of oil pipe; Dope spreads upon on the screw thread of oil pipe equably, and the present invention is simple to operate, high efficiency; Do not exist dope to smear uneven problem, oil pipe is connecting
Connect in screw thread and the use, the oil pipe screw thread can and not get rusty because of thread gluing and damage, and the oil well production cycle is long, has remarkable economic efficiency.
Description of drawings
Fig. 1 is an installation diagram of the present invention.
The specific embodiment
Below in conjunction with Fig. 1 embodiments of the invention are described.
Embodiments of the invention comprise crowded oil gun 1, rifle lid 2, pressure cap 3, oil duct joint 5, shell 8, scrape oil jacket 9, and rifle lid 2, shell 8 are sleeved on the oil duct joint 5, and pressure cap 3 is connected with oil duct joint 5; The right side of pressure cap 3 compresses the interior shoulder of rifle lid 2, and rifle lid 2 is pushed down the left side of shell 8, and the interior shoulder of shell 8 is pressed on the outer circular bead surface on the oil duct joint 5; Rifle lid 2, pressure cap 3, oil duct joint 5, shell 8 are linked into an integrated entity, squeeze oil gun 1 and be connected, scrape the outer end that oil jacket 9 is installed in shell 8 with rifle lid 2; Button connected till mounting means was general, also can have alternate manner to connect, and made to scrape oil jacket 9 and link together with shell 8 and can be synchronized with the movement just; Endoporus 4, linked hole 6 are arranged on the oil duct joint 5; There is guide head 10 oil duct joint 5 outer ends, and the guide head 10 of oil duct joint 5 inserts in the oil pipes 11 during use, scrape on the outer wall that oil jacket 9 is sleeved on oil pipe 11; Make and form cavity 7 between shell 8 and the oil pipe 11; Cavity 7 communicates with crowded oil gun 1 inside through endoporus 4, linked hole 6, and the screw thread of oil pipe 11 is in 7 li of cavitys, makes the screw thread of oil pipe 11 can touch the dope that charges into cavity 7.Scrape oil jacket (9) and processed by nonmetallic materials, its hardness is Shao Shi 20-80, is convenient to frizing, can not damage the screw thread of oil pipe 11.
The present invention also can smear dope on the drilling rod pin thread, if be used for smearing dope on the drilling rod pin thread, the oil pipe 11 among Fig. 1 is a drilling rod 11 just, also can be used for smearing dope on the well tubing pin thread.
