Abstract
A rotary type descaling bottom plug. The problem that the existing descaling bottom plug does not have a rotating function and therefore descaling capacity is poor is mainly solved. The method is characterized in that: the inner side of the bottom of the upper joint (6) is connected with a guide rod (1), the outer side of the upper joint is connected with a guide rail (4), a spring (5) is arranged between the guide rod (1) and the guide rail (4), and the inner wall of the guide rail (4) is provided with a spiral groove; the outer sleeve of guide rail (4) has scraping head (2), is connected with slider (3) on scraping head (2), and the helicla flute on guide rail (4) is arranged in to slider (3) lower extreme. The rotary descaling bottom plug has a rotating function, is high in descaling capacity and improves descaling efficiency.
Description
Technical Field
The utility model relates to an oil field, a rotation type scale removal end is stifled specifically says so.
Background
After the working barrel of the current water injection well underground water distributor is scaled, the throwing and fishing device can not pass through the water distributor, and the working barrel needs to be scraped. The existing descaling bottom plug does not have a rotating function, and has poor descaling capability on excessively thick scale.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that the existing descaling bottom plug does not have the rotating function and the descaling capability is poor, the utility model provides a rotary descaling bottom plug which has the rotating function and strong descaling capability and improves the descaling efficiency.
The technical scheme of the utility model is that: a rotary descaling bottom plug comprises an upper joint, wherein the inner side of the bottom of the upper joint is connected with a guide rod, the outer side of the bottom of the upper joint is connected with a guide rail, a spring is arranged between the guide rod and the guide rail, and the inner wall of the guide rail is provided with a spiral groove; the outer portion of the guide rail is sleeved with a scraping head, a sliding block is connected to the scraping head, and the lower end of the sliding block is arranged in a spiral groove in the guide rail.
And two ends of the spring are respectively propped against the sliding block and the upper joint.
The guide rail is provided with two spiral grooves, two groups of sliding blocks are respectively positioned in the two spiral grooves, each group of sliding blocks is composed of two sliding block single bodies, and the sliding block single bodies are respectively fixed on the scraping head.
The utility model discloses following beneficial effect has: due to the adoption of the scheme, the scraping head can slide along the spiral groove on the guide rail along with the sliding block, so that the scraping head rotates, the surface of the working cylinder of the water distributor is scraped in a rotating manner, the descaling capacity is high, and the descaling efficiency is improved.
Drawings
FIG. 1 is an external view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
In the figure, 1-a guide rod, 2-a scraping head, 3-a slide block, 4-a guide rail, 5-a spring and 6-an upper joint.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figures 1 and 2, the rotary descaling bottom plug comprises an upper connector 6, wherein the inner side of the bottom of the upper connector 6 is connected with a guide rod 1, and the bottom end of the guide rod 1 is a cone. The outer side of the bottom of the upper joint 6 is connected with a guide rail 4, the guide rail 4 is a circular pipe, is sleeved outside the guide rod 1, has a gap with the guide rod 1, is internally provided with a spring 5, and the inner wall of the guide rail 4 is provided with two spiral grooves which are arranged in the same rotating direction. The outer sleeve of guide rail 4 has scraping head 2, and 2 surfaces of scraping head are a plurality of spiral beads, and the direction of rotation of bead reaches spiral groove on guide rail 4. The inside of the scraping head 2 is connected with a sliding block 3, and the lower end of the sliding block 3 is arranged in a spiral groove on the guide rail 4. The two groups of sliding blocks 3 are respectively positioned in the two spiral grooves, each group of sliding blocks 3 is composed of two sliding block single bodies, and the sliding block single bodies are respectively fixed on the scraping head 2. And two ends of the spring 5 are respectively pressed against the sliding block 3 and the upper joint 6.
When the scraper is in work, the upper joint 6 is connected with the bottom of the throwing and fishing device and goes down the well along with the throwing and fishing device, and at the moment, the sliding block 3 drives the scraping head 2 to be positioned at the lower end of the guide rod 1 under the elastic force of the spring 5. When the throwing and fishing device passes through the water distributor, the scraping head 2 and the surface of a working cylinder of the water distributor generate friction, if scale exists on the surface of the working cylinder, the lower joint 6, the guide rail 4 and the guide rod 1 continue to descend, the scraping head 2 slides along the spiral groove on the guide rail 4 along with the sliding block 3 under the blocking of the scale, and simultaneously rotates, the dead weight of the throwing and fishing device is utilized to generate compression effect on the spring 5, the scraping head 2 is pressed downwards, and the scale is scraped.
Claims (3)
1. The utility model provides a rotation type scale removal end is stifled, includes top connection (6), its characterized in that: the inner side of the bottom of the upper joint (6) is connected with a guide rod (1), the outer side of the upper joint is connected with a guide rail (4), a spring (5) is arranged between the guide rod (1) and the guide rail (4), and the inner wall of the guide rail (4) is provided with a spiral groove; the outer sleeve of guide rail (4) has scraping head (2), is connected with slider (3) on scraping head (2), and the helicla flute on guide rail (4) is arranged in to slider (3) lower extreme.
