Description
Technical field:
The utility model relates to the drill string cleaning device that uses in a kind of drilling well trip-out process, particularly a kind of automatic drill string scraper.
Background technology:
Because there is viscosity in drilling fluid, the normal extension of drilling fluid is bonded at the drill string surface and along with drill string is taken out of well head together in the drilling well trip-out process.The effect of drilling fluid is exactly an equilibrium strata pressure except lubricating drilling tool, transmitting more of paramount importance the water-horse power in pit shaft.In trip-out process, generally trip out 3~4 root posts and irritate a drilling fluid.So, reduce to take place the danger of overflow in order to prevent that drilling fluid from consuming excessively.Be necessary to design a kind of device that can carry out the scraping cleaning,, reduce the consumption of drilling fluid so that in time clear up the drilling fluid of drill string remained on surface to the drill string surface.Yet existing such drill string cleaning surfaces tool construction is simple, and cleaning effect is not obvious, the long-term manual operation of lead-tong man in needing during cleaning, and operation is dangerous big.
The utility model content:
The technical problem that the utility model will solve provides a kind of automatic drill string scraper, and this device has been realized the drilling fluid on automated cleaning drill string surface, and cleaning effect is good, need not the staff and operates constantly, guarantees drilling safety.It is poor to have overcome existing drill string cleaning surfaces instrument cleaning effect, the long-term manual operation of lead-tong man in needing during cleaning, the dangerous big deficiency of operation.
The technical scheme that the utility model is taked is: a kind of automatic drill string scraper comprises and scrapes mud cleaning mouth and tool body; Two tool body one sides are connected through hinge, and opposite side is equipped with automatic snap close, and two tool body closures can form the stage body of a hollow; The tool body upper end is connected with the self-adapting stretching pipe nipple; Self-adapting stretching pipe nipple upper end is equipped with scrapes mud cleaning mouth; Scrape mud cleaning mouth and comprise elastic metallic ring, rubber ring and hairbrush; The size adjustment device is installed on the elastic metallic ring, and elastic metallic ring installed inside has rubber ring, and the rubber ring installed inside has hairbrush; The tool body bottom is provided with balancing weight and strong magnets pin, and the tool body bottom is provided with the drilling fluid refluxing opening.
Tool body inside is provided with erection device.
The beneficial effect of the utility model is: the utility model is scraped mud cleaning mouth owing to having adopted, thereby has the good advantage of cleaning effect; Owing to adopted the self-adapting stretching pipe nipple, thereby can regulate the suitable different BHA sizes of finish dimensional automatically, realized the function of the drilling fluid on automated cleaning drill string surface, need not the staff and operate constantly, guarantee drilling safety.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical section structure sketch map of the utility model.
Fig. 3 is that the A-A of Fig. 1 is to generalized section.
The specific embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of automatic drill string scraper comprises and scrapes mud cleaning mouth 1 and tool body 3; Two tool body 3 one sides are connected through hinge, and opposite side is equipped with automatic snap close 4, folding automatically, and two tool body 3 closures can form the stage body of a hollow; Tool body 3 upper ends are connected with self-adapting stretching pipe nipple 2, self-adapting stretching pipe nipple 2 can axially with freely stretch in the radial direction, self-adapting stretching pipe nipple 2 employing high resiliency, high-intensity rubber are processed; Self-adapting stretching pipe nipple 2 upper ends are equipped with scrapes mud cleaning mouth 1; Scrape mud cleaning mouth 1 and comprise elastic metallic ring 11, rubber ring 12 and hairbrush 14; Size adjustment device 13 is installed on the elastic metallic ring 11, can controls the size of scraping mud cleaning mouth 1, to adapt to different drill string sizes; Elastic metallic ring 11 installed inside have rubber ring 12, and rubber ring 12 installed inside have hairbrush 14; Tool body 3 bottoms are provided with balancing weight 10 and strong magnets pin 5, are used for overcoming the frictional force that produces when putting forward on the drill string, guarantee the stability of instrument, during use the utility model are placed in place, make strong magnets pin 5 firmly be adsorbed on the rotating disk; Tool body 3 bottoms are provided with drilling fluid refluxing opening 6, and tool body 3 inside are provided with erection device 9.
When the utility model uses, at first need open automatic snap close 4, the utility model is launched; Adjust the position of the utility model then; When drill string 8 is positioned at the center of the utility model, the utility model is closed up,, and strong magnets pin 5 is adsorbed on the rotating disk with automatic snap close 4 lockings.Rotate size adjuster 13, the fit dimension between adjustment elastic metallic ring 11 and the drilling tool.After adjusting finishes, with 13 lockings of size adjustment device.On carry drill string 8, drill string 8 is successively through drilling fluid refluxing opening 6, tool body 3 with scrape mud cleaning mouthful 1.Be provided with erection device 9 in the tool body 3, can effectively prevent drill string 8 deflection significantly.When drill string 8 when scraping mud cleaning mouthful 1, residual drilling fluid carries out scraping on 14 pairs of drill strings 8 of hairbrush, the rubber ring 12 that connects hairbrush 14 is discontinuous shape, rubber ring 12 is provided with 8 fractures, so that tool joint can be passed through smoothly.Scrape the drilling fluid that chips away and get in the recycling cavity 7, flow back to pit shaft through drilling fluid refluxing opening 6, can not cause raffinate to pile up along the inclined-plane of balancing weight 10.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
