Abstract

The utility model discloses a mud cleaner for oil drilling, including holding the frame and holding the fixed orifices that sets up on the frame, the central point that holds the frame puts and has installed and has bored into the pipe, holds the built-in a plurality of bracing pieces that are equipped with of frame, and the sliding sleeve has been installed at the top of bracing piece, and the interlude has the slide bar in the sliding sleeve, and the scraper blade has been installed to the one end of slide bar, and the cover is equipped with the both ends of spring and connects connecting plate and sliding sleeve respectively on the slide bar. Under the effect of the retraction force of spring, the sword of scraping on the scraper blade is stable and is pasted tight drilling rod outer wall, rotatory removal in-process about the drilling rod, can scrape sticky silt that has on the drilling rod outer wall, because the silt of scraping is the slice, can not directly get into the drilling through drilling rod and drilling pipe cooperation gap, but through guide surface inclined way to holding in the frame, thereby can effectively reduce the volume that returns the drilling rod in-process well silt and bring into the drilling, the good lubricity of drilling fluid to the drilling rod of newly pouring into the drilling.

Description

Mud cleaner for petroleum drilling

Technical Field

The utility model belongs to the technical field of the oil drilling is clean, concretely relates to mud cleaner for oil drilling.

Background

Oil drilling is the drilling of holes in oil fields by means of extendable drill rods. In order to reduce the friction force of underground silt to the drilling rod, a large amount of drilling fluid is injected into the drilling well in the drilling process, so that the drilling rod can be cooled on one hand, and the surface of the drilling rod is lubricated on the other hand, so that the purpose of protecting the drilling rod is achieved.

In the process of drilling the drill rod, the drill rod does not directly drill, but needs to move up and down in a circulating manner, so that the drilling fluid mixed with a large amount of mud is brought out through the upward-moving drill rod, and on the other hand, the aim of ensuring that the wall surface of a drilled well is relatively flat is achieved. The defects are as follows: because the drilled silt is infiltrated by the drilling fluid and then is bonded on the outer wall of the drill rod, the bonded silt can enter the drill well along with the drill rod, and the lubricating effect of the drilling fluid on the drill rod is seriously weakened.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mud cleaner for oil drilling to the silt of gluing among the solution prior art can be followed the drilling rod and get into the problem in the drilling.

In order to achieve the above object, the utility model provides a following technical scheme: the mud cleaner for petroleum drilling comprises a containing frame and a fixing hole formed in the containing frame, wherein a drilling pipe is installed in the center of the containing frame, a plurality of supporting rods are installed in the containing frame, sliding sleeves are installed at the tops of the supporting rods, sliding rods are inserted in the sliding sleeves in a penetrating mode, a scraper is installed at one ends of the sliding rods, a connecting plate is installed at the other ends of the sliding rods, springs are sleeved on the sliding rods, and the two ends of each spring are respectively connected with the connecting plate and the corresponding sliding sleeve.

Preferably, the top of the drilling pipe is provided with a guide surface, and the guide surface is an annular inclined surface.

Preferably, the sliding sleeve is of a round sleeve structure, and the sliding rod is of a round rod structure.

Preferably, the scraper is of a square plate structure, one end of the scraper is provided with a scraping edge, and the scraping edge is of a double-faced sharp edge structure.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a mud cleaner for oil drilling, under the effect of the back power of contracting of spring, the sword of scraping on the scraper blade is stable and is pasted tight drilling rod outer wall, rotatory removal in-process about the drilling rod, can scrape sticky silt that has on the drilling rod outer wall, because the silt of scraping is the slice, can not directly get into in the drilling well through drilling rod and the fit gap of drill pipe, but through guide face ramp to holding in the frame, thereby can effectively reduce down to return the volume that the interior silt of drilling rod in-process brought into the drilling well, the drilling fluid of guarantee newly pouring into in the drilling well is to the good lubricity of drilling rod.

In the figure: 1 containing frame, 2 drilling pipes, 3 guide surfaces, 4 support rods, 5 sliding sleeves, 6 sliding rods, 7 scraping plates, 8 scraping edges, 9 connecting plates, 10 springs and 101 fixing holes.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, 2 and 3, a mud cleaner for oil drilling comprises a containing frame 1 and a fixing hole 101 annularly arranged at the bottom of the containing frame 1, wherein the containing frame 1 is of a round frame structure with an open upper end, the fixing hole 101 is of a round hole structure and is used for penetrating an anchor bolt and driving the anchor bolt into the ground, a press cake at the top of the anchor bolt tightly presses the inner bottom surface of the containing frame 1, so that the containing frame 1 can be stably arranged at the edge of a drilling well, a drilling pipe 2 is arranged at the central position of the containing frame 1, the drilling pipe 2 is of a round pipe structure, the height of the drilling pipe 2 is 30 cm, the diameter of the inner wall of the drilling pipe 2 is larger than the diameter of a drill rod by 2 mm, a guide surface 3 is arranged at the top of the drilling pipe 2, the guide surface 3 is an annular lower inclined surface, when sticky silt on the outer wall of the drill rod is scraped to the top of the drilling pipe 2, the guide surface 3 is arranged in the containing frame 1, four support rods 4 are, top welding sliding sleeve 5 of bracing piece 4, it has slide bar 6 to slide interlude in sliding sleeve 5, sliding sleeve 5 is the circle cover structure, slide bar 6 is the circle pole structure, four slide bar 6 interior correspond terminal surface welding scraper blade 7, scraper blade 7 is the square plate structure of vertical setting, the interior side that corresponds of four scraper blades 7 is equipped with scrapes sword 8, scrape the setting of sword 8, satisfy when inserting the drilling rod in the pipe of boring 2, the point portion of scraping sword 8 supports under spring 10's elastic support and presses the drilling rod outer wall, it is two-sided sharp sword structure to scrape sword 8.
