Abstract
The utility model discloses a kind of oil well blowout hookup, comprise piston body, described piston body is a hollow cylinder structure and circumferential wall offers sieve aperture, immediately below piston body, correspondence arranges packoff nipple, described packoff nipple inside offers chamber, large footpath and path chamber from top to bottom successively, described path chamber internal diameter is consistent with piston body external diameter, and when ensureing that piston body falls in path chamber completely, path cavity wall is to the complete shutoff of sieve aperture on piston body.Suspension step is formed between described chamber, large footpath and path chamber, described piston body upper end connects fuel-displaced cover by screwed top connection, fuel-displaced cover sets out hydraulic fluid port, fuel-displaced cover upper end connects polished rod, described fuel-displaced cover external diameter is greater than the outwardly formation chuck of piston body, and fuel-displaced cover lower end is suspended on described step by chuck.The utility model makes polished rod of pumping well have no progeny to fall into well to cause pollution in wide area.
Description
Technical field
The utility model relates to down-hole kit, specifically a kind of oil well blowout hookup.
Background technology
At present, after controlling polished rod break, the technology of blowout is provided with ball-and-seat after being oil pipeline with two kinds: one, pre-anti-down oil ejection; Two is the control valves installing shutoff packing box polished rod hole in polished rod sealer upper end., there is significant pollution accident in its shortcoming: as ball-and-seat after measuring station lost efficacy, add the pipeline spray of falling oil well and substantial oil just may be caused to spray.Through on-site verification, the control valve in polished rod hole causes period of validity short due to polished rod longtime running, ineffective.
Polished rod of pumping well is disconnected fall into wellhead polish rod sealer under blowout can be caused to pollute, chief reason: to be that oil pipeline falls oily, liquid sprays from Polish rod packing cartridge apertures.Two is as oil well has expansion of liquids in blowing ability or tubing string, sprays in packing.Due to unmanned during tide on the well group of sea, beach, under preventing polished rod slow, cause horse head to touch curved polished rod, sea, beach well group rod-pumped well does not all make anti-release side's clamp under polished rod, just gas blowout accident can occur as polished rod break falls into below well head.Three is all have ball-and-seat after current oil pipeline, and as reliable in sealed, oily spray volume is few, can not cause great pollution; As ball-and-seat after measuring station lost efficacy, added the pipeline spray of falling oil well and substantial oil just may be caused to spray, significant pollution accident occurred.Four is if to adopt on raised platform around a well tide unmanned in guard's patrol in extra large oily land, and pumping well polish rod breaks the well that falls, and long-time blowout, will cause great sea pollution accident.Meanwhile, polished rod break falls well piston and touches pump, and damage sucker rod, oil pipe, pump, shorten pump detection period, and even clash into and cause boll-weevil hanger pipe nipple disconnected de-, whole pipe column falling well, causes fishing string even overhaul.
Utility model content
The purpose of this utility model is to provide a kind of oil well blowout hookup, polished rod of pumping well is had no progeny fall into well to cause pollution in wide area.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, a kind of oil well blowout hookup, comprise piston body, described piston body is a hollow cylinder structure and circumferential wall offers sieve aperture, and immediately below piston body, correspondence arranges packoff nipple, described packoff nipple inside offers chamber, large footpath and path chamber from top to bottom successively, described path chamber internal diameter is consistent with piston body external diameter, and when ensureing that piston body falls in path chamber completely, path cavity wall is to the complete shutoff of sieve aperture on piston body.
Suspension step is formed between described chamber, large footpath and path chamber, described piston body upper end connects fuel-displaced cover by screwed top connection, fuel-displaced cover sets out hydraulic fluid port, fuel-displaced cover upper end connects polished rod, described fuel-displaced cover external diameter is greater than the outwardly formation chuck of piston body, and fuel-displaced cover lower end is suspended on described step by chuck.
Described piston body lower end is by lower contact connecting with pumping rod pipe nipple.
Described packoff nipple upper end is threaded connection oil pipe.
Described packoff nipple lower end is threaded connection lower oil pipe.
Compared to prior art, the utility model has following beneficial effect:
The utility model structure is simple, but practical, by the sieve aperture moved up and down and then easily on shutoff piston, polished rod of pumping well is had no progeny fall into well to cause pollution in wide area.And fuel-displaced cover is setting on packoff nipple step, play suspension effect, the inner-cavity structure of the Different Diameter that packoff nipple inside is offered serves multiple effect, namely path chamber is used for shutoff sieve aperture, the step formed between the inner chamber of Different Diameter has coordinated again end stand under the external diameter of fuel-displaced cover, overall structure can be made to be suspended on herein, so the utility model has good practical value and promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil well blowout hookup of the present utility model.
In figure: upper oil pipe 1, lower oil pipe 2, packoff nipple 3, polished rod 4, sucker rod substitute 5, top connection 6, sieve aperture 7, fuel-displaced cover 8, oil-out 9, piston body 10, lower contact 11.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
With reference to accompanying drawing 1, a kind of oil well blowout hookup, comprise piston body 10, described piston body is a hollow cylinder structure and circumferential wall offers sieve aperture 7, immediately below piston body, correspondence arranges packoff nipple 3, and described packoff nipple inside offers chamber, large footpath and path chamber from top to bottom successively, and described path chamber internal diameter is consistent with piston body external diameter, when ensureing that piston body falls in path chamber completely, path cavity wall is to the complete shutoff of sieve aperture on piston body.Suspension step is formed between described chamber, large footpath and path chamber, described piston body upper end connects fuel-displaced cover 8 by screwed top connection 6, fuel-displaced cover sets out hydraulic fluid port 9, fuel-displaced cover upper end connects polished rod 4, described fuel-displaced cover external diameter is greater than the outwardly formation chuck of piston body, and fuel-displaced cover lower end is suspended on described step by chuck.Described piston body lower end is by lower contact 11 connecting with pumping rod pipe nipple 5.Described packoff nipple upper end is threaded connection oil pipe 1.Described packoff nipple lower end is threaded connection lower oil pipe 2.
