Description
Technical field
The present invention relates to the device that a kind of oil field machinery oil is used, is injectant blending device under a kind of pump for pumping well.
Background technology
When heavy oil wells oil pumping, between viscous crude and sucker rod, produce friction and make the descending difficulty of sucker rod, it can not normally be pumped.Solving this class well one of difficult way of pumping is to add thinner in sleeve pipe, make reducing thick oil viscosity, but because the thinner adding in sleeve pipe can not fully mix with well liquid, the thinner adding does not reach desirable effect, the difficult problem of pumping still can not get solving.On-the-spot used thinner eddy flow vortex mixer, need to be by being just lowered into pump in pump barrel, because the pump supporting with it is Special Pump, formed by two pump barrels, its discharge capacity is that upper pumpage subtracts lower pumpage, in order to obtain the discharge capacity needing, so, the pump footpath of lower pump is less, the external diameter of the mechanism that can pass through is also less, therefore, the centralizer of thinner eddy flow vortex mixer, the external diameter of flight is less, and the gap between sleeve pipe is very large, liquid circulation is out-of-date can not produce rotation, the thinner adding is not had to the effect that eddy flow mixes, thereby do not reach due effect after implementing.
Summary of the invention
The object of the invention is to design injectant blending device under a kind of pump for pumping well, the thinner mixing is evenly mixed with well liquid, reduce viscosity of thickened oil, guarantee oil well is normally produced.
The object of the present invention is achieved like this: comprise hollow pump, locked joints, butt joint, lock dog, interior lock tube, exterior lock tube, butt tube, outer spring, inner spring, spring base, urceolus, mixing plant, ball-and-seat, plug is stifled, interior box cupling, shear pin, lower seal, cross over pipe, the top of butt tube has window, in window, put into lock dog, while having interlocking slot, locked joints to be sleeved on outside butt tube on locked joints, the outside of lock dog enters in the interlocking slot of locked joints, lock tube in installing in butt tube, the outer wall of interior lock tube blocks lock dog, and interior lock tube can slide in butt tube, and butt tube is set with exterior lock tube outward, exterior lock tube can slide on butt tube, and butt tube has interior shoulder, outer shoulder, exterior lock tube has interior shoulder, interior lock tube has outer shoulder, in when the interior shoulder of butt tube contacts with the outer shoulder of interior lock tube, lock tube is limited, when the outer shoulder of butt tube contacts with the interior shoulder of exterior lock tube, exterior lock tube is limited, under interior lock tube, inner spring is installed, outer spring is installed under exterior lock tube, the top of spring base is connected with the bottom of butt tube, make inner spring seat on the upper surface of spring base, outer spring seat is on the outside shoulder of spring base, and the bottom of spring base is connected with the top of mixing plant, and the bottom of mixing plant connects ball-and-seat, the bottom of locked joints is connected with the top of urceolus, plug is stifled to be connected in interior box cupling by shear pin, and plug blocks up between interior box cupling has lower seal, urceolus, cross over pipe is linked together by interior box cupling, cross over pipe Shang You UNICOM groove, and butt joint is connected to the bottom of hollow pump, has the outer locked groove supporting with lock dog on the outer wall of butt joint.
On butt tube inwall, install sealing ring, the gap between sealing ring sealing butt tube and the bottom of interior lock tube, butt tube and butt joint.
The invention has the beneficial effects as follows: after putting in place under hollow pump, by butt joint, butt tube is connected with mixing plant, thinner from ground through hollow stem, hollow pump, ball-and-seat flows out, with well liquid together through mixing plant, interflow is mixed, the thinner injecting is fully mixed with out well liquid, improve viscosity reducing effect, viscosity of thickened oil is reduced, mobility improves, heavy oil wells can normally be produced, mixing plant of the present invention G.I.H together with pump barrel, do not pass through pump barrel, thereby the external diameter of mixing plant is large, and the gap between urceolus is little, mixed liquor must pass through mixing plant, can realize fully and mixing, viscosity reducing effect improves greatly, therefore, the present invention has significant economic benefit.
