Abstract
A thread compound spreading device adopts the structure that an oil passage joint is sleeved by a gun cover and a housing; a pressing cap is connected with the oil passage joint; the right end surface of the pressing cap is pressed tightly on the inner shoulder of the gun cover; the gun cover is pressed on the left end surface of the housing; the inner shoulder of the housing is pressed on the outer shoulder surface of the oil passage joint; an oil extrusion gun is connected with the gun cover; an oil scraping sleeve is mounted at the outer end of the housing; an inner hole and a communication hole are formed in the oil passage joint; and a guide head is arranged at the outer end of the oil passage joint. During use, the guide head of the oil passage joint is inserted into an oil pipe, and the oil scraping sleeve is mounted on the outer wall of the oil pipe in a sleeving manner, so that a cavity is formed between the housing and the oil pipe, and a screw thread of the oil pipe is arranged in the cavity; when the oil scraping sleeve is mounted on the outer wall of the oil pipe in a sleeving manner, the cavity can be fully filled with thread compound by operating the oil extrusion gun; and then the oil extrusion gun is drawn outwards, and the oil scraping sleeve moves along the screw thread of the oil pipe, so that the thread compound is spread on the screw thread of the oil pipe uniformly, and the problem that the thread compound is spread unevenly is solved. Therefore, during a screw thread connecting process and a use process of the oil pipe, damage, caused by thread gluing and rusting, on the screw thread of the oil pipe is avoided.
Description
Technical field
The utility model 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 purpose of the utility model is a kind of dope application device of design, makes the oil pipe screw thread evenly smear dope, overcomes the problem of above-mentioned existence.
The purpose of the utility model is achieved in that and comprises crowded oil gun, rifle lid, pressure cap, oil duct joint, shell, scrapes oil jacket that 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.
The utility model beneficial effect be: after the frizing cover was sleeved on the oil-pipe external wall, operation was squeezed oil gun and just can be made and be full of dope in the cavity, more outwards during the crowded oil gun of drawing; Scrape oil jacket and pass by from the screw thread of oil pipe, dope spreads upon on the screw thread of oil pipe equably, and the utility model is simple to operate; High efficiency; Do not exist dope to smear uneven problem, oil pipe is in thread and use, and the oil pipe screw thread can and not get rusty because of thread gluing and damage; The oil well production cycle is long, has remarkable economic efficiency.
Description of drawings
Fig. 1 is the installation diagram of the utility model.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
The embodiment of the utility model comprises crowded oil gun 1, rifle lid 2, pressure cap 3, oil duct joint 5, shell 8, scrapes 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 utility model also can be smeared 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.
