Abstract
The utility model relates to the field of workover treatment during oil and natural gas development, in particular to a sucker rod oil wiper in an oil well sleeve. The sucker rod oil wiper mainly consists of a flange gland, an oil wiping rubber ring tray, a sealing steel ring, an oil wiping rubber ring and a sleeve head. A rubber ring tray shoulder is suspended in the sleeve head, the oil wiping rubber ring is arranged in the oil wiping rubber ring tray, the sealing steel ring is embedded in a steel ring slot at the upper part of the sleeve head, and the flange gland and the sleeve head are fixedly connected through bolts. The sucker rod oil wiper is arranged on a controllable sleeve flange without well control, raw oil on the outer wall of the sucker rod is wiped under the action of the oil wiping rubber ring, and the wiped raw oil is leaked into a well mouth sleeve through a side hole and a bottom oil wiping channel. The sucker rod oil wiper disclosed by the utility model realizes oil wiping and leaking in a sleeve, has the advantages of simple structure, convenience for mounting and smooth oil leakage, prevents raw oil of the outer wall from removing to pollute the environment on the ground when a sucker rod lifts up, realizes oil wiping and leaking operations in the sleeve, simplifies the construction process and improves the working efficiency.
Description
Technical field:
The utility model relates to the workover treatment field in the petroleum and natural gas exploitation, and the sucker rod oil wiper is used in particularly a kind of workover treatment.
Background technology:
At present, the sucker rod oil wiper is installed in more than the production wellhead master valve, also needs the installation outlet pipeline according to " well control " standard-required; The crude oil that discharging sucker rod outer wall scrapes off; Cause outlet line to install and supporting trouble, the viscous crude circulation is not smooth, causes environment pollution easily.Inapplicable controlled snubbing serving needs.
The utility model content:
The technical problem that the utility model will solve provides sucker rod oil wiper in a kind of sleeve pipe, realizes frizing draining in the sleeve pipe, saves the installation and the supporting operation of floor outlet pipeline, increases work efficiency, and draining is unobstructed, reduces deficiencies such as ground installation, environment pollution.
The technical scheme of the utility model is: mainly by flange gland 1, scrape factice rim bearing pallet 5, ring gasket 3, scrape factice ring 4, casing head 6 is formed.It is characterized in that glue rim bearing pallet 5 shoulders hang in the casing head 6, scrape in the factice rim bearing pallet 5 and scrape factice ring 4 that ring gasket 3 embeds in the casing head 6 upper steel ring recess, gland flange 1 is fixedly connected with casing head 6 usefulness bolts 2.
The sucker rod oil wiper is installed on the controlled not kill-job casing flange; Sucker rod outer wall crude oil is struck off under the effect of scraping the factice ring; This part crude oil through side opening 8 and bottom frizing passage 9 drainings in the well head sleeve pipe; Flow into through controlled outlet then and receive fuel tank, and oil wiper upper flange lid is designed with general clip head, can be connected with present sucker rod preventer.In a preferred embodiment, describedly scrape in the factice rim bearing pallet 5 that bottoms are taper in the oil wiper down going channels 9.
Sucker rod oil wiper in the utility model sleeve pipe has been realized frizing draining in the sleeve pipe, has simple in structure; Easy for installation; Draining is unobstructed, has avoided in the sucker rod process outer wall crude oil pollution ground environment that comes off, and has realized frizing and draining in the sleeve pipe; Reduce working procedure, improved operating efficiency.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
1. sucker rod oil wiper assembled on site in the sleeve pipe
During controlled snubbing serving, according to standard-required controlled snubbing serving device is installed, comprising casing head 6.Overlapped sucker rod 7 with glue rim bearing pallet 5 and be placed in the casing head 6 this moment; Then sucker rod guiding short circuit pass from bottom to top scrape factice ring 4 after, top puts gland flange 1, mentions sucker rod guiding short circuit with rod elevator; Be inserted in well head ring gasket 3; Sucker rod 7 buckle that have in the sucker rod guiding short circuit of scraping factice ring 4 and flange gland 1 and the well, transfer sucker rod and guide short circuit again, scrape factice ring 4 along with under be advanced in the frizing glue rim bearing pallet 5; Be connected flange gland 1 with casing head 6 fasteningly then with general well head bolt 2, can accomplish installation.The order of taking apart and the reversed in order of above-mentioned installation.
2. sucker rod oil wiper The field in the sleeve pipe
When running into the controlled snubbing serving of pumpingh well, through aforesaid operations method assembling sucker rods oil wiper, when needs play the sucker rod operation; Sucker rod oil wiper suit in the sleeve pipe is crossed sucker rod 7, be fixed on then on the casing flange, the crude oil of outer wall is under the effect of support glue ring 4 elastic forces when normally carrying sucker rod; Hold sucker rod 7 outer walls tightly, though the up factice ring 4 of scraping of sucker rod has up trend, can not be up by 1 restriction of flange gland; Compress the last hole that has sealed flange gland 1; Played and put forward two effects of sucker rod frizing and sealing, this moment, oil wiper down going channel 9 was opened with side opening 8, and the crude oil that strikes off is got in the sleeve pipe.After proposing rod collar; When need sitting elevator and transferring sucker rod, scrape factice ring 4 receive stopping of glue rim bearing pallet 5 can not be descending, scrape factice ring 4 and close glue rim bearing pallet 5 lower passage; This moment is through side opening 8 and atmosphere; Guarantee not form negative pressure in the sleeve pipe, make in the unimpeded inflow connected tank of the interior crude oil of sleeve pipe, guaranteed controlled snubbing serving frizing effect.Reduced the draining pipeline of outside sucker rod oil wiper in the past, made frizing and draining better effects if to have guaranteed that controlled not kill-job plays bar flow chart smooth implementation.
The sucker rod oil wiper mainly comprises three parts in the sleeve pipe: the one, and flange gland 1; Upper design has general clip head; The bottom is designed to general big flange arrangement, is convenient to install and be connected the sucker rod blowout hookup, and indoor design is a taper box cupling leading cone; Can guide rod collar and pass through smoothly, avoid the scratching shoulder; The 2nd, scrape the factice ring, be designed to the discoid of pore, to adopt to be at least 1 disk installation, 3 disks combinations are installed as the best, are convenient to the distortion of glue core, also improve glue core frizing effect and application life; The 3rd, glue rim bearing pallet has suspension, support, draining and connectivity capabilities, is sucker rod oil wiper critical component in the sleeve pipe; There is shoulder suspension the upper end, and cavity can installation test sucker rod oil wiper glue ring result of use, double side opening or single side opening; Circumferentially upper-side hole is at least 1, and 6 is best, has draining and is communicated with atmospheric action; Can improve frizing and draining effect, lower passage realizes support, draining, set upright and effect such as guiding.
The interior sucker rod oil wiper design of this sleeve pipe has simple in structure, easy for installation, and frizing is effective; Draining is unobstructed, and safe and reliable advantage can be used for the operation of controlled not kill-job sucker rod frizing; Can effectively avoid sucker rod contaminated equipment and environmental problem, have positive environmental protection effect.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
