Description
Technical field
The utility model relates to a kind of drilling-rod external wall with mud-scraping ring and include the mud-scraping apparatus of this mud-scraping ring.
Background technology
In oil, gas drilling process,, must when drilling well, use drilling fluid in order to guarantee to carry out smoothly drillng operation.Therefore when playing drilling rod, the drilling rod column that elevates from the down-hole can be taken drilling fluid out of the rig floor table top, and the work scene of making is not only dirty but also sliding and abnormally dangerous, has increased working strength of workers.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of drilling-rod external wall with mud-scraping ring and the mud-scraping apparatus that includes this mud-scraping ring.
In order to achieve the above object, the utility model drilling-rod external wall mud-scraping ring comprises an elastic ring body, and the inner surface and the drilling-rod external wall of described ring body are suitable, and one is shaped on support on the circumference of the external surface of described ring body.
A kind of mud-scraping apparatus comprises mud-scraping ring, also comprises a housing, a upper cover plate, a lower cover.On described inner walls, radially be provided with clamping device, being supported and fixed on the clamping device on the described mud-scraping ring excircle.Described upper cover plate is fixed on housing top, and lower cover is fixed on lower housing portion.
After adopting the mud-scraping ring and mud-scraping apparatus of said structure, drilling rod upwards promotes in well, and mud-scraping ring is attached to drilling-rod external wall all the time, the drilling fluid that is bonded at drilling-rod external wall is struck off, thereby prevent that effectively drilling fluid from being taken out of.
Description of drawings
Fig. 1 is the structural representation of the utility model mud-scraping ring.
Fig. 2 is that the A-A of the utility model mud-scraping ring shown in Figure 1 is to cross-sectional schematic.
Fig. 3 is the cross-sectional schematic of the utility model mud-scraping apparatus.
The specific embodiment
As depicted in figs. 1 and 2, the utility model drilling-rod external wall mud-scraping ring comprises an elastic ring body 6, and the inner surface and the drilling-rod external wall of described ring body are suitable, and being shaped on of one supports 61 on the circumference of the external surface of described ring body.
Above-mentioned elastic ring body 6 should adopt high resilience, material wear-resisting, that elongation at break is bigger to make, as rubber, polyurethane etc., preferably acrylonitrile-butadiene rubber.Its cross section can be circle, ellipse etc.; Also can in the middle of make hollow, i.e. hollow and annular (as shown in Figure 3), make things convenient for drill pipe coupling 8 by the time compression surplus, high resilience again arranged.
On the excircle of elastic ring body, its material can be identical with ring body integratedly in above-mentioned support, also can be different, and its shape can also can be on the circumference that is disposed on mud-scraping ring for circular, is dentation.
During for the mud-scraping ring axially loaded, the mud-scraping ring high resilience, and can be close to drilling rod 7 outer walls, and scrape mud, as further improvement of the utility model, in described support, be folded with spring steel plate 5.As shown in Figures 2 and 3, wherein spring steel plate 5 can only be arranged on the support section of mud-scraping ring, also can extend to a part in the mud-scraping ring body, to increase the elasticity of whole mud-scraping ring.
As shown in Figure 3, the utility model includes the mud-scraping apparatus of above-mentioned mud-scraping ring, comprises mud-scraping ring, also comprises a housing 1.On described inner walls, radially be provided with clamping device, being supported and fixed on the clamping device on the described mud-scraping ring excircle.
The structure of above-mentioned clamping device is: comprise a hollow support plate 2 and a hollow pressing plate 3 suitable with it that radially is arranged in the housing, the middle vacancy of described gripper shoe 2 and pressing plate 3 and the excircle of mud-scraping ring are suitable, and described hollow pressing plate 3 is connected by bolt 4 with hollow support plate 2.
When using for scraper, set upright effective, indeformable when being hit load, mud-scraping ring is compressed with than large space, it is the taper upper cover plate that described housing is provided with a upper end, is provided with through hole in the center of described upper cover plate, and described through hole is suitable with the drilling rod external diameter.The structure of above-mentioned upper cover plate is: comprise 12 gusset (not shown)s, and a base plate, a bullet, the moulding of a top board assembly welding, the upper cover plate integral slab can be fixed on the housing by modes such as welding, be threaded.
When preventing that drilling rod from pulling out of hole, it is too high that drill bit rises, and makes drill bit that mud-scraping ring is damaged, be connected with a lower cover 10 at described housing, be provided with through hole in the center of described lower cover 10, this through hole should be suitable with the drilling rod external diameter, so that drilling rod passes through, but less than the external diameter of drill bit.This lower cover is fixed on the housing by screw thread 11, so that dismounting.
The use of drilling-rod external wall mud-scraping apparatus of the present utility model is as follows: when pulling out of hole in oil, gas drilling process, after kelly bar laid down, mud-scraping apparatus is enclosed within on the drilling rod 7.With sling drilling tool in the well of elevator.The big quadrel of rotating disk is put forward with hanging big quadrel hook.The drilling-rod external wall mud-scraping apparatus is pushed into downwards on the well head horn mouth, under the big quadrel of rotating disk.Then, the big quadrel of rotating disk is hung get back in the big quadrel of the rotating disk hole.During trip-out, the drilling-rod external wall mud-scraping apparatus is just under the big quadrel of rotating disk.Drilling rod is up carried, and scraper upper cover plate bullet enters the big quadrel of rotating disk lower end, and the drilling fluid of setting upright the drilling rod 7 column outer walls that scraper will rise up strikes off.The drilling liquid flow of wiping off is got back in the well to the well head horn mouth.When the drilling rod that upwards promotes had arrived drill pipe coupling 8, because the elongation at break of scraping mud (acrylonitrile-butadiene rubber) ring is more than or equal to 400%, box cupling was stretched big mud-scraping ring aperture and is passed through mud-scraping ring.Drill pipe coupling 8 is by behind the mud-scraping ring, because the acrylonitrile-butadiene rubber mud-scraping ring has better elastic, incites somebody to action the outer wall that is attached to drilling rod 7 tightly again, strikes off the drilling fluid that is bonded at drilling rod 7 outer walls.After playing finishing drilling, the big quadrel of rotating disk is proposed, the drilling-rod external wall mud-scraping apparatus is taken out from well head, clean up with clear water, pull out of hole and use next time.
