Description
Technical field
The present invention relates to use engineering oilfield downhole operation technical field more particularly to a kind of oil field operation scraper.
Background technique
During oil field operation, the burs such as greasy dirt, fouling, cured, existing cleaning side are often had on down-hole oil tube
Method is manually to be cleared up by the effect of frictional force between belt and oil pipe oil pipe, this method is not by belt
Only inefficiency, and biggish physical load is caused to staff.
Summary of the invention
The invention reside in overcome the existing method efficiency for manually clearing up down-hole oil tube dirt present in background technique
Low time-consuming and laborious problem, and a kind of oil field operation scraper is provided.The oil field operation scraper, can strike off automatically
Burs, the high efficiency and time conservation such as greasy dirt, fouling on oil pipe, cured are laborsaving.
The present invention solves the problems, such as that it can reach by following technical solution: the oil field operation scraper includes toroidal shell
Body is fitted with main rotating cylinder in the shell, and main rotating cylinder is fitted in shell, and shell top and the bottom pass through bearing and main rotating cylinder
Connection；Lower part of the housing is provided with several openings；Main rotating cylinder inner wall is connected to the lower part straightway of helical form steel wire；On helical form steel wire
Portion's spiral section passes through upper cover centre bore and stretches out upper cap upper surface；The outer wall of main rotating cylinder is set with driven gear, the quilt installed
Moving gear corresponding housing opening；It is fixedly installed with hydraulic motor on the outer wall of shell, is set in the rotation axis of hydraulic motor
Driving gear, driving gear are engaged with driven gear.
The present invention can have the following beneficial effects: the oil field operation scraper compared with above-mentioned background technique, can
It wipes the mud on drilling tubular and the silt of adherency etc. off, strikes off the various foulings on underground work oil pipe, greasy dirt, cured etc. and adhere to
In the adjunct of oil-pipe external wall；The present invention is used as driving power source using hydraulic motor, since shaft mouth operation worker is in substantially
Moist and underwater work can reduce the unexpected electric leakage of well head worker generation, the generation of electric shock accidents using hydraulic, improve well head work
The safety coefficient manually made.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings and the specific embodiments:
As shown in attached drawing 1, Fig. 2, Fig. 3, the oil field operation scraper, including shell 1, main rotating cylinder 2, under main rotating cylinder 2
Portion is provided with several openings, and the main rotating cylinder 2 is inserted into shell 1, and 1 top of shell, lower part pass through upper bearing (metal) respectively
9, lower bearing 10 is connect with main rotating cylinder 2；The opening of 1 upper end of shell is buckled with circular ring shape upper cover 4 or shell 1
The opening of upper end is connect by multiple fixing bolts 7 with upper cover 4；Main 2 inner wall of rotating cylinder is connected to the lower part of helical form steel wire 3
Straightway 3-2；Helical form steel wire top spiral section 3-1 passes through 4 centre bore of upper cover and stretches out upper cap upper surface；Driving assembly includes liquid
Pressure motor 5 and driving gear 6, the outer wall of main rotating cylinder 2 are set with driven gear 13 or driven gear 13 and main rotating cylinder
2 outer wall links into an integrated entity, 6 corresponding housing of driving gear, 1 opening installed；It is fixedly installed on the outer wall of shell 1
Hydraulic motor 5 is set with driving gear 6 in the rotation axis of hydraulic motor 5, and driving gear 6 is engaged with driven gear 13；Hydraulic horse
Driving assembly is constituted up to 5 and driving gear 6；The lower end of 1 outer wall of shell outer 11 with outward extension is set on outer 11
There are multiple fixation holes 12；The lower end suit sealing ring 8 and sealing ring 8 of main rotating cylinder 2 are located at main 2 lower end of rotating cylinder
1 lower end of bottom surface and shell inner wall between, effectively raise the leakproofness between main rotating cylinder 2 and shell 1.
The oil field operation scraper, the outer wall of driven gear and main rotating cylinder link into an integrated entity, effectively raise by
Bonding strength between moving gear and main rotating cylinder avoids that gear slip phenomenon occurs；Upper cover 4 by multiple fixing bolts 7 with
Be detachably connected at 1 upper end opening of shell, both increased the bonding strength between upper cover 4 and shell 1, at the same also facilitate upper cover 4 with
Installation and removal between shell 1.
The oil field operation scraper during oil pipe is lifted up, opens in use, shell 1 is mounted at well head
Hydrodynamic pressure motor 5, hydraulic motor 5 drive driven gear 13 to rotate by driving gear 6, and then main rotating cylinder 2 is driven to rotate, main
Rotating cylinder 2 drives helical form steel wire 3 to rotate, and during oil pipe rises, the helical form steel wire 3 covered on oil pipe will be on oil pipe
The burs such as greasy dirt, fouling, cured strike off, and the operation of helical form steel wire is nor affected at the box cupling between oil pipe.
