This guarantee flexible drifting ware of scraping of unblocked impact brill formula of test channel, connect the connector through the well testing steel wire, transfer with 2000 per hour speed in oil pipe, reach to meet and hinder behind the position, carry repeatedly and putting, dependence instrument self weight, but the drill bit autogiration of lower extreme, the mediation tight point, utilize self gravity to drive that the drill bit creeps into and wax scraping device rotates transferring the in -process, utilize gravity to make the drill bit reset lifting the in -process, realize a second stroke, to the oil recovery factory since in the pit the tubular column wax deposition condition also can dredge, can improve oily well yield greatly.
Description
Technical field
This utility model relates to drifting device technical field, and a kind of impact ensureing that TCH test channel is unimpeded is bored formula and stretched
Scraping drifting device.
Background technology
In oil well logging, the first object completing to be successfully tested is to ensure that test instrunment can arrive log measurement smoothly
Well section, original technology is to use quickly to remove to increase the weight of, and carries out drifting by gravity methods, but owing to down-hole is hampered reason very
Many, mostly can not be successful, the situation that is hampered includes the low oil-polluted water water filling after the process of employing at present of oil field, water filling main line, branch line
Float in service life long lines, polluting stratum containing material, irony chip, water drive, poly-driving are interlocked in the plane
Distribution, strengthens with interlayer contradiction and causes impurity more, owing to adsorption makes tubing string narrow, affects the normal production of well,
Also cannot ensure that test instrunment is successfully tested, the such as patent of Patent No. 201520346416.9, including rotating top connection
And connected main shaft, main shaft fixed light cage type scraper the most successively and rhombus scraper, the lower end of main shaft connects
Turbine, although improve efficiency of removing contamination, but the effect removed contamination is bad, affects follow-up work.
Summary of the invention
The purpose of this utility model is to provide a kind of impact ensureing that TCH test channel is unimpeded to bore formula to stretch scraping drifting device,
With the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer: a kind of impact ensureing that TCH test channel is unimpeded
Brill formula is stretched scraping drifting device, and including union joint, the bottom of described union joint is installed with paraffin scraper, the end of described paraffin scraper
End is installed with overcoat, and the inner chamber of described overcoat is provided with built-in spring, and the bottom of described built-in spring is provided with screw rod, described
Screw rod runs through overcoat, and the left and right sides of described screw rod is equipped with lock pin, and the outside of described lock pin is connected with overcoat, described spiral shell
The bottom of swing arm is provided with drill bit.
Preferably, the outer wall circumference of described union joint is provided with reinforcement.
Preferably, described built-in spring is provided with elastomer block with the junction of overcoat.
Compared with prior art, the beneficial effects of the utility model are: the impact that this guarantee TCH test channel is unimpeded is bored formula and stretched
Contracting scraping drifting device, is connected union joint by piano wire, and with 2000 rate discharge hourly in oil pipe, arrival is hampered
Behind position, handling repeatedly, rely on instrument own wt, the drill bit of lower end can rotate automatically, dredges tight point, in decentralization process
Utilize self gravitation to drive drill bit to creep into and paraffin scraper rotates, utilize gravity to make drill bit reset during upper carrying, it is achieved second
Individual stroke, also is able to dredge due to down-hole string wax deposition situation to oil recovery factory, can be greatly improved oil well yield.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of impact brill formula ensureing that TCH test channel is unimpeded
Flexible scraping drifting device, including union joint 1, is connected union joint 1 by piano wire, on the outer wall circumference of described union joint 1
Being provided with reinforcement 8, can be strengthened the intensity of union joint 1 by reinforcement 8, the bottom of described union joint 1 is installed with paraffin cutting
Device 2, the bottom of described paraffin scraper 2 is installed with overcoat 4, and the inner chamber of described overcoat 4 is provided with built-in spring 3, described built-in bullet
Spring 3 is provided with elastomer block 9 with the junction of overcoat 4, can be strengthened the elasticity of built-in spring 3, described built-in spring by elastomer block 9
The bottom of 3 is provided with screw rod 6, and described screw rod 6 runs through overcoat 4, and the left and right sides of described screw rod 6 is equipped with lock pin 5, described
The outside of lock pin 5 is connected with overcoat 4, and the bottom of described screw rod 6 is provided with drill bit 7, with 2000 speed hourly in oil pipe
Transfer, after arriving the position that is hampered, handling repeatedly, rely on instrument own wt, the drill bit 7 of lower end can rotate automatically, and dredging is hampered
Point, utilizes self gravitation to drive drill bit 7 to creep in decentralization process and paraffin scraper 2 rotates, utilize gravity to make during upper carrying
Drill bit 7 resets, it is achieved second stroke, also is able to dredge due to down-hole string wax deposition situation to oil recovery factory.
During use, by piano wire, union joint 1 is connected, with 2000 rate discharge hourly in oil pipe, arrive
