The well head drill pipe wiper
Technical field
The utility model relates to a kind of scraper, relates in particular to a kind of scraping the mud rope sling and comprising the well head drill pipe wiper that this scrapes the mud rope sling of drilling-rod external wall of removing.
Background technology
In the normal trip-out process of wellbore construction such as oil, natural gas, scientific investigation, because the inertia that promotes from the down-hole of the viscosity of drilling fluid self and drilling rod, make drilling fluid be carried out well head by drilling rod, cause the drilling fluid waste, the construction plant mire is wet and slippery, be inconvenient to operate construction, influence production safety.As the strong wind weather even the well site of floating in the air, influence surrounding enviroment.Artificial removing not only increases labour intensity, and influence operating personnel, to observe periphery dynamic, accident such as be unfavorable for handling that falling object from high altitude, blowout are speedily carried out rescue work.
Summary of the invention
In order to overcome above-mentioned defective, the well head drill pipe wiper that the utility model provides a kind of use to scrape the mud rope sling and comprise rope sling has solved and has removed the problem that labour intensity is big, safety is low in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is:
Support is provided with link, hangs on the link and scrapes the mud rope sling.
Described support is closed type or open loop type.
The described mud rope sling of scraping is, the inside of rubber tube is provided with can free movable charges, and the two ends of rubber tube are respectively equipped with wire rope.
Described scrape the mud rope sling for one, two strands or multiply, adjustable length, it is shaped as circle, semicircle, triangle, prismatic, ellipse, groove shaped, rectangle, square.
Described two ends of scraping the mud rope sling can be provided with movable steel bushing.
Described link is provided with 2 groups or 3 groups.
Described support is provided with the connection pin.
The utility model has the advantages of as follows:
When adopting the mud-scraping apparatus of said structure, drilling rod upwards promotes in well, scrapes the mud rope sling and is attached to drilling-rod external wall all the time, the drilling fluid on the drilling rod is struck off, thereby prevent that effectively drilling fluid from being taken out of, and can fully observe well head place liquid level state.
In addition, the utility model dismounting flexible, easy to carry, simple in structure, laborsaving efficient, be beneficial to observe the well head state, applicable to characteristics such as different drilling assembly.

The specific embodiment
Embodiment 1
Shown in Fig. 1,2,7,8,, be provided with a support and three elasticity rope slings for split type carrying rope sling well head drill pipe wiper.Support is a closed type, divide big, little two parts, form by steel plate welding or casting, be fixed together by connector during use, support is provided with the connection pin, be used to hang three groups of iron links scraping the mud rope sling and be evenly distributed on support, the general big part inwall of support is welded with two groups of iron links, part inwall that support is little and is welded with one group of iron link and is used for hanging and scrapes the mud rope sling; As shown in Figure 5
Scrape the mud rope sling and comprise rubber tube and wire rope, the inside and the two ends of fill-type rubber tube are respectively equipped with seizing wire, described scrape the mud rope sling can be for one, two strands, three strands or multiply all can, adjustable length, scrape the mud rope sling be shaped as circle, semicircle, triangle, prismatic, ellipse, groove shaped, rectangle, other shapes such as square all can, and the two ends of scraping the mud rope sling can be fixed with steel bushing respectively, as shown in figure 12.The inside of described rubber tube is provided with charges, and these charges are rope, and this rope can be free movable in rubber tube.
Also steel bushing can be movably arranged on the two ends of scraping the mud rope sling in the specific implementation, steel bushing can also be set all can implement.
Embodiment 2
Shown in Fig. 3,4,9,10, be embedded rope sling well head drill pipe wiper, support is arranged to open loop type, and support bends with spring steel and forms, and the inwall of support evenly is welded with three groups of steel loops and is used for hanging and scrapes the mud rope sling.The structure of scraping the mud rope sling is with embodiment 1.
Use of the present utility model is as follows:
1. the use of split type carrying rope sling well head drill pipe wiper
During trip-out at first with support casing on kelly bar or drilling rod, after being connected and fixed with the connection pin, again with high resilience, wear-resisting, the big material of tension elongation at break, the fill-type rubber rope sling that the pure rubber hose of making as silicon rubber is made walks around kelly bar or drilling rod is hung on every group of iron hoop of the separating stent-graft that is welded into or casts with steel plate, is placed on well head and gets final product.Utilize the deadweight of scraper to overcome drilling rod and scrape friction between the mud rope sling, or utilize the weight of another elevator to overcome drilling rod and scrape friction between the mud rope sling the pulling force of scraper to the pulling force of scraper.It is standby to remove cleaning after trip-out is finished.
2. the use of embedded rope sling well head drill pipe wiper
The support casing that at first will be rolled by steel spring plate during trip-out is walked around rope sling kelly bar or drilling rod again and is hung every group of iron hoop respectively and be pushed into well head horn mouth place up and down and get final product on kelly bar or drilling rod.It is standby to remove cleaning after trip-out is finished.
