Description
Technical field
the present invention relates to the aid of drifting during water injection well in oil fields test, specifically a kind of injection well testing self-rotary drifting instrument.
Background technology
current water injection well due to the problem such as water treatment, well-flushing, causes tubing string fouling undergauge in well in long-term injecting water process, causes water flooding well pipe to damage increase, injection rate reduces, and energy consumption increases, and tests the well that is hampered and increases.For improving test success rate further, reducing because pipe damages the use electric consumption caused, must drifting work be carried out.Drifting has two kinds of methods: one is conventional drifting, utilize the descending impact force of the deadweight of instrument, scraper on instrument strikes off side-wall begriming in descending process, wiper cross-sectional area great Yi is hampered, meets card, adopt large diameter wire rope cannot realize airtight drifting, the be hampered well large to overflow cannot carry out drifting, and drifting success rate is about 30%, and drifting success rate is on the low side.Two is electronic driftings, gone into the well drifting drill bit behind precalculated position by cable, in the location, interface that is hampered, drifting instrument is fixed on tube inner wall, energising downhole drill bit rotates, dirt obstinate on tubing wall is carried out drilling and struck off, electronic drifting tools selection motor is owing to being subject to spacial influence and cable, voltage, current limit, diameter is less, rotating speed and power little, greasy dirt softer in well or polymer can only be removed, in the use procedure of electronic drifting instrument, instrument failure rate is high, and maintenance and repair cost is high.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of injection well testing self-rotary drifting instrument.
the utility model is realized by following technical proposals:
injection well testing self-rotary drifting instrument, comprising: suspension joint, support, spring, support arm, roller, axle, axle sleeve, ball, lining, pipe nipple, wire brush, lappet.Suspension joint and the support of described injection well testing self-rotary drifting instrument mount, the bottom of support is threaded with support arm, the top of support arm and the lower end of suspension joint are provided with spring, and the middle part of support arm is arranged with two rollers, and the bottom of support arm is connected with sleeve thread, axle is provided with in axle sleeve, the lower step of axle is provided with ball, and on axle, the bottom of ball is provided with lining, and lining is connected with sleeve thread, the lower end of axle connects with pipe nipple, lappet successively, and pipe nipple is provided with wire brush.
the surface of the pipe nipple in above-mentioned injection well testing self-rotary drifting instrument is provided with " S " type aligned apertures, the in-built steel wire in hole.
lappet in above-mentioned injection well testing self-rotary drifting instrument is single leaf helical structure.
the beneficial effects of the utility model are: drifting when being applicable to the test of oil field water injection well in oil fields, novel in design, be easy to processing, and rational in infrastructure, drifting convenient and reliable operation, reduces maintenance cost, increase work efficiency.
Accompanying drawing explanation
fig. 1-the utility model master looks broken section structural representation.
in accompanying drawing, 1. suspension joint, 2, support, 3. spring, 4. support arm, 5. roller, 6. rotating shaft, 7. axle sleeve, 8. ball, 9. lining, 10. pipe nipple, 11. wire brushes, 12. lappets.
Detailed description of the invention
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
embodiment 1
a kind of injection well testing self-rotary drifting instrument is made up of suspension joint 1, support 2, spring 3, support arm 4, roller 5, axle 6, axle sleeve 7, ball 8, lining 9, pipe nipple 10, wire brush 11, lappet 12.Suspension joint 1 and the support 2 of described injection well testing self-rotary drifting instrument mount, the bottom of support 2 is threaded with support arm 4, the top of support arm 4 and the lower end of suspension joint 1 are provided with spring 3, the middle part of support arm 4 is arranged with two rollers 5, the bottom of support arm 4 is threaded with axle sleeve 7, axle 6 is provided with in axle sleeve 7, the lower step of axle 6 is provided with ball 8, on axle 6, the bottom of ball 8 is provided with lining 9, lining 9 is threaded with axle sleeve 7, the lower end of axle 6 connects with pipe nipple 10, lappet 12 successively, and pipe nipple 10 is provided with wire brush 11.
embodiment 2
method of operating: first, the suspension joint 1 of injection well testing self-rotary drifting instrument is mounted on conventional weighted lever bottom, installs lubricator, preventing spray head, whether inspection screw thread, sealing ring damage, smear silicone grease at connection of thread, adopt Ф 5.6mm cable to connect instrument and go into the well; Secondly, under injection well testing self-rotary drifting instrument after well head, control well head water filling at 100m
3
about/d; 3rd, the water injection well for blank tubing can take the mode of the positive well-flushing in drifting limit, limit, and during well-flushing, for the water injection well of horn mouth above layer position, water yield is larger than water injection rate, and for the water injection well of horn mouth below layer position, water injection rate is larger than water yield; 4th, must at the uniform velocity in cable decentralization process, notice that observation is hampered, when when injection well testing self-rotary drifting instrument is hampered, and this is hampered there is not casing deformation, bending, kickoff point (KOP) in the degree of depth, can on carry injection well testing self-rotary drifting instrument and repeatedly transfer.To having casing deformation, bending water injection well and inclined shaft, apart from casing deformation, become curved, slow down and transfer slowly in 50m place above the kickoff point (KOP) degree of depth, can not lead to as being hampered, above carrying instrument; 5th, injection well testing self-rotary drifting instrument, by stopping after the degree of depth that is hampered transferring, removes injection well testing self-rotary drifting instrument repeatedly in the position that is hampered, remove the foul of the position that is hampered.As above carry injection well testing self-rotary drifting instrument process Instrumental meet card stop immediately on carry, turn off water outlet and water filling, more slowly on carry, observe tension variations situation at any time; 6th, after passing to desired depth, upper portable cable, speed that injection well testing self-rotary drifting instrument rises can not more than 2000m/h, and be noted observing chance card.7th, injection well testing self-rotary drifting instrument is carried and must be slowed down to during well head 100m, during distance well head 30m, with hand to well head, test strobe first closes 2/3, and releasing of brake is soundd out, guarantee that injection well testing self-rotary drifting instrument is in lubricator, with force (forcing) pump pressurization, close test strobe rapidly.
