Description
Technical field
The utility model relates to oil gas water well operation environment protection device, especially relates to a kind of shaft mouth operation oil pipe clean environment firendly device.
Background technology
Along with the deep development day by day of oil gas field, oil gas water well operation is more and more frequent, and tripping out of oil pipe often can take down-hole oil-containing mixed liquor to ground.As cleaning, collect thoroughly, except causing site work environment to be deteriorated, affecting operating worker mood, causing outside unnecessary consequence, mixed liquor also may be scattering on the ground around operation wellhead, penetrates in soil.This not only causes energy waste, but also pollutes local soil environment, even also may threaten the clean of underground water, bring out comparatively serious ecological environment problem.Present oil field operation scene is equipped with multiple labour protection equipment and well control facility, but still exists the impact of well head environment.
For the problems referred to above, propose the various oil pipe of a kind of adaptation and effectively improve operating environment, preventing the shaft mouth operation oil pipe clean environment firendly device of shaft mouth operation contaminated environment.
Utility model content
The purpose of this utility model is avoid the deficiencies in the prior art and provide shaft mouth operation oil pipe clean environment firendly device.
The technical solution of the utility model is: shaft mouth operation oil pipe clean environment firendly device, and comprise friction top, air bag, body, pin and air valve, described body has flange, uniform flange hole on flange; Described body upper end is provided with half slot, and the balloon conduit major diameter fit on air bag, the upper surface of described body is also laid with screwed hole; Be provided with the flank of tooth and air storing cavity inside described air bag, on the downside of described air bag, be provided with step surface, compress by between the lower cylinder of friction top and body; Described friction top is provided with the balloon conduit major diameter fit on a hole and air bag, and described friction top upper side edge all lays counterbore, and boring and bayonet fittings, friction top is fastenedly connected by pin and body.
The balloon conduit of described air bag, through the hole on friction top and body upper half-round slot, is connected with air valve sealing.
Described friction top be 2 semi-circular.
Compared with prior art, the utility model has the advantages that: can be connected by nut plunger with wellhead flange, do not affect the operation such as various lower oil tubes, downhole tool of normal oil well; Two semi-circular friction tops are set, are convenient to the fastening installation of air bag; In addition, by changing the friction top of different bore, the accommodation of the utility model to various downhole tool and oil pipe obtains expansion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is friction top, 2 is air bag, and 3 is body, and 4 is pin, and 5 is air valve, and 101 is hole, 102 is counterbore, and 103 is lower cylinder, and 201 is balloon conduit, and 202 is the flank of tooth, and 203 is air storing cavity, 204 is step surface, and 301 is half slot, and 302 is screwed hole, and 303 is flange hole, and 304 is flange.
Detailed description of the invention
Shaft mouth operation oil pipe clean environment firendly device, comprises friction top 1, air bag 2, body 3, pin 4 and air valve 5, and described body 3 has flange 304, uniform flange hole 303 on flange 304; Described body 3 upper end is provided with half slot 301, and on air bag 2 balloon conduit 201 major diameter fit, the upper surface of described body 3 is also laid with screwed hole 302; Be provided with the flank of tooth 202 and air storing cavity 203 inside described air bag 2, on the downside of described air bag 2, be provided with step surface 204, compress by between the lower cylinder 103 of friction top 1 and body 3; Described friction top 1 is provided with a hole 101 and balloon conduit 201 major diameter fit on air bag 2, and described friction top 1 upper side edge all lays counterbore 102, and boring coordinates with pin 4, and friction top 1 is fastenedly connected by pin 4 and body 3.
The balloon conduit 201 of described air bag 2, through the hole 101 on friction top 1 and body 3 upper half-round slot 301, is tightly connected with air valve 5.
Described friction top 1 be 2 semi-circular.
Concrete operational method: first by corresponding with wellhead flange for the flange hole 303 on flange 304 and be solidly connected by Nut column jam-pack.Inflated in air bag 2 by balloon conduit 201, make gassy in air storing cavity 203, make the flank of tooth 202 adapt to OIH pipe external diameter, then close gas check valve 5, what then start tubing string in well trips out operation.
