Description
Technical field
The utility model relates to a kind of polished rod sealer, particularly a kind of rod-pumped well NEW TYPE OF COMPOSITE medium charge type polished rod sealer.
Background technology
In known technical field, along with the exploitation of bridge mouth region block, stratum energy constantly declines, and between pumpingh well occurs, artificial situation is more frequent.Rod-pumped well not fluid time, polished rod does not have well liquid to lubricate, well head packing and polished rod just there will be dry grinding, at this moment the surface temperature of polished rod is up to more than 100 degree, phenomenon that well head packing easily occurs " burning packing ", burning out in various degree because well head packing has existed when oil well is fuel-displaced, easily occurring that well head runs oily phenomenon if pulled tight time not anxious, cause environment pollution, production declining, with
Time add the management difficulty of oil recovery work.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of rod-pumped well NEW TYPE OF COMPOSITE medium charge type polished rod sealer.
Its technical scheme is: comprise well mouth sealing device, I grade of sealed solid section, liquid medium filling chamber, II grade of sealed solid section, rubber seal section, body, well mouth sealing device is provided with on the top of body, I grade of sealed solid section is connected in the bottom of well mouth sealing device, liquid medium filling chamber is provided with below I grade of sealed solid section, II grade of sealed solid section is provided with below liquid medium filling chamber, rubber seal section is provided with below II grade of sealed solid section, well mouth sealing device comprises high temperature high voltage resistant telescoping tube, HTHP is met an urgent need sealing device, seamless polish rod clamp, the high temperature high voltage resistant telescoping tube lower end HTHP that is threaded is met an urgent need sealing device, HTHP is met an urgent need the seamless polish rod clamp of sealing device lower end seamless link.
Meet an urgent need sealing device, seamless polish rod clamp of above-mentioned high temperature high voltage resistant telescoping tube, HTHP is sleeved on polished rod.
The beneficial effects of the utility model are: sealingly secure is reliable, and HTHP sealing of meeting an urgent need can temporarily substitute flexible sealing, is convenient to replacing high temperature high voltage resistant telescoping tube, can closes well head, prevent blowout during light rod-broken; Realize the sealing to sucker rod and sealer annular space by I grade of sealed solid section, II grade of sealed solid section, inject associated media by liquid medium filling chamber and reach and reduce polished rod friction resistance, corrosion-resistant effect.Open I grade of sealed solid section after closing rubber seal section, replacing that II grade of sealed solid realizes sealed packing.
