Description
One, technical field
The present invention is the device of oil field oil recovery usefulness, is a kind of hollow stem water-mixed wellhead device.
Two, background technology
In heavy oil wells and paraffin-troubled well, the employing hollow stem water mixing viscosity reduction that has, dewaxing method oil pumping.Hollow stem water mixing principle is that water or steam through heating are got into crude oil Hybrid Heating diluent crude oil on hollow stem and the pump from the well head high-pressure hose, reaches the purpose of viscosity reduction, wax removal, makes oil well ability ordinary production.Adopting the high-pressure hose heating is that high-pressure hose one end is fixed on ground, and the other end connects with moving hollow polished rod upper end, makes the water of heating or steam well head high-pressure hose get into hollow stem.But the high-pressure hose poor heat resistance, incompatibility is passed through Steam Heating; High-pressure hose also will rotate and folding and unfolding with pumping unit horsehead, and the application life of high-pressure hose is short; High-pressure hose is exposed to outdoor, and capacity suffers lawless person's destruction.
Three, summary of the invention
The objective of the invention is to design a kind of hollow stem water-mixed wellhead device, the water of heating or steam connect formation through fixed pipelines and inject and the output passage with well head, make the viscous crude dilution, and wax deposition is removed, and guarantees viscous crude, paraffin-troubled well ordinary production, raising oil well economic benefit.
The objective of the invention is to realize like this: be made up of pressure release joint, water mixing threeway, front band, flow tee, lower catch hoop, blind flange, bolt, suspension seal nipple, well head four-way, polished rod, oil pick-up tube, UNICOM's joint, separated press pump tube, separated compression leg plug, sealed tube, sealed tube top screw thread connects with the interior minor thread of pressure release joint, and major thread connects with the water mixing threeway in the pressure release joint; The water mixing threeway is connected by front band with flow tee, and flow tee is connected by lower catch hoop with blind flange, and blind flange and well head four-way are by Bolt Connection; Connect with water mixing threeway internal thread at a distance from press pump tube top screw thread, the suspension seal nipple is suspended in the well head four-way, and suspension seal nipple bottom connects with oil pick-up tube; Polished rod passes sealed tube, and the polished rod bottom connects with the UNICOM joint, UNICOM joint bottom with connect at a distance from the compression leg plug; Separated compression leg plug is in the press pump tube; On the pressure release joint relief hole is arranged, the water mixing mouth is arranged in the water mixing threeway, oil-out is arranged on the flow tee; Between sealed tube and the separated press pump tube water mixing passage is arranged; Between oil pick-up tube and the separated press pump tube oil discharge passage is arranged, on UNICOM's joint linked hole is arranged, linked hole and the inner UNICOM of separated compression leg plug.
On the suspension seal nipple sealing ring is arranged.
The invention has the beneficial effects as follows: mix medium and get into hollow stem from water mixing mouth, water mixing passage, do not need high-pressure hose, heatproof is high; Withstand voltage height adapts to and mixes steam, and is fixed on ground; All adopt the metal steel, combine together with mouth of pumped oil well, thereby long service life; Pumpingh well is ordinary production for a long time, and is good in economic efficiency.
