Technical field
The present invention is the working equipment of oilfield oil well well workover, is a kind of underground helicoid hydraulic motor antiseize device.
Background technique
When oil field is drilled with the workover treatments such as underground cement plug, need using helicoid hydraulic motor, by ground input high pressure liquid stream punching
Dynamic helicoid hydraulic motor makes it generate rotation.Therefore, the high pressure liquid stream of ground input will by helicoid hydraulic motor, helicoid hydraulic motor by stator and
Rotor composition, the two cooperation is close, and when high pressure liquid stream is impacted, rotor generates rotation and bit is driven to carry out workover treatment.It is existing
For the high voltage power liquid that field uses by carrying some sundries when pipeline, these sundries enter the gap between stator and rotor
When, it be easy to cause rotor to be stuck, prevents helicoid hydraulic motor from working, cause workover treatment that cannot go on smoothly, generate great warp
Ji loss.
Summary of the invention
The purpose of the present invention is designing a kind of underground helicoid hydraulic motor antiseize device, overcome the deficiencies in the prior art is prevented miscellaneous
Object enters in helicoid hydraulic motor, avoids the above problem, and oil-water well workover treatment is enable to go on smoothly.
The object of the present invention is achieved like this：Including anti-flushing well device, block material device, anti-flushing well device is connected to block material
On device, block material device is connected on the helicoid hydraulic motor of underground, and anti-flushing well device is washed when external pressure is higher than internal pressure
Well liquid can open linked hole and flow into internal, the power fluid of driving helicoid hydraulic motor when helicoid hydraulic motor works from the external of anti-flushing well device
Outside cannot be flowed to from the inside of anti-flushing well device, block material device includes hypostasis pipe, block material cover, lower contact, the top of block material cover
Be provided with screen slot, the upper end of block material cover blocks, flow liquid stream can only through the screen slot, the lower part of block material cover and lower contact it is upper
The connection of portion's internal screw thread, the lower part of hypostasis pipe and the upper external thread of lower contact connect, the internal diameter of hypostasis pipe and the outer diameter of block material cover
Difference forms annular hypostasis chamber, and the top of hypostasis pipe is connected to the lower part of the anti-flushing well device.
The anti-flushing well device includes top connection, spring base, spring, upper seal, sliding sleeve, lower seal, top connection
On have linked hole, sliding sleeve is mounted in top connection, and the lower outer diameter of the sliding sleeve covering linked hole, sliding sleeve is less than outside top
Diameter, the various outer diameter position of sliding sleeve and the inner wall of top connection are engaged, close under having between the lower part of sliding sleeve and the inner wall of sliding sleeve
Seal has upper seal between the top of sliding sleeve and the inner wall of sliding sleeve, upper seal is on the linked hole, lower sealing
Circle is under the linked hole, and spring is placed on sliding sleeve, and spring base is mounted in top connection, spring base pressing spring,
After hydraulic coupling pushes sliding sleeve uplink compressed spring, sliding sleeve can not cover the linked hole, and hydraulic coupling pushes the power of sliding sleeve to disappear
Spring pushes sliding sleeve to cover the linked hole again afterwards.
The beneficial effects of the invention are as follows：The present invention is mounted on the helicoid hydraulic motor of underground, with oil pipe G.I.H, drives spiral shell
When bar drill has the power fluid of work by the present invention, sundries is blocked, and sundries will not enter helicoid hydraulic motor, and sundries bit freezing is not present
The problem of, therefore, the present invention can reach purpose of design, can guarantee that oil-water well workover treatment is gone on smoothly, and have significant economical
Benefit.
Detailed description of the invention
Attached drawing 1 is the installation diagram of the embodiment of the present invention.
Specific embodiment
1 pair of the embodiment of the present invention is illustrated with reference to the accompanying drawing.
As shown in Figure 1, the embodiment of the present invention includes anti-flushing well device, block material device, and anti-flushing well device is connected to block material
On device, block material device is connected on the helicoid hydraulic motor of underground, and anti-flushing well device is washed when external pressure is higher than internal pressure
Well liquid can open linked hole and flow into internal, the power fluid of driving helicoid hydraulic motor when helicoid hydraulic motor works from the external of anti-flushing well device
Outside cannot be flowed to from the inside of anti-flushing well device, block material device includes hypostasis pipe 8, block material cover 9, lower contact 12, block material cover 9
Top is provided with screen slot 11, and the upper end of block material cover 9 blocks, and flow liquid stream can only through the screen slot 11, the lower part of block material cover 9 and
The upper internal threaded of lower contact 12 connects, and the lower part of hypostasis pipe 8 is connect with the upper external thread of lower contact 12, hypostasis pipe 8 it is interior
The outer diameter difference of diameter and block material cover 9 forms annular hypostasis chamber 10, and the top of hypostasis pipe 8 is connected under the anti-flushing well device
Portion.The anti-flushing well device includes top connection 1, spring base 2, spring 3, upper seal 4, sliding sleeve 5, lower seal 7, top connection
There is linked hole 6 on 1, sliding sleeve 5 is mounted in top connection 1, and sliding sleeve 5 covers the linked hole 6, and the lower outer diameter of sliding sleeve 5 is less than
Top outer diameter, the various outer diameter position of sliding sleeve 5 and the inner wall of top connection 1 are engaged, the lower part of sliding sleeve 5 and the inner wall of sliding sleeve 5
