Abstract
The utility model relates to a sand sticking-preventing, gas locking-preventing and scaling-preventing tubing pump without a fixed valve and with a long plunger. The tubing pump comprises a sucker rod, a tubing, a pump adapter, a scale-settling barrel, an intermediate adapter, a pump barrel, the plunger and a pump coupling, the lower end of the sucker rod is connected with the plunger, the tubing, the pump adapter, the scale-settling barrel and the intermediate adapter which are connected with one another are sleeved on the sucker rod sequentially from the top down, the lower end of the intermediate adapter is connected with the pump barrel, the lower end of the pump barrel is sequentially connected with the pump coupling, an anti-collision nipple, an anti-collision coupling, a sand-settling pipe and a bottom coupling, an anti-collision piston is arranged in the bore of the lower end of the anti-collision nipple, a plug is arranged in the bore of the lower end of the bottom coupling, and the pump barrel is provided with oil-draining and exhaust holes. The increase of the jumping degree in the process of the entry of liquid into the pump can effectively prevent scaling ingredients from staying to be aggregated, and also can help to separate and sink sand; the conventional fixed valve coupling is not used any more, consequently, the mechanism under the pump is simplified, and the occurrence of the pump leakage or blockage phenomenon in the past is prevented; and pump sticking is prevented.
Description
Technical field
The utility model relates to a kind of tubing pump that does not have the long-plunger sand control gas-tight antiscale of standing valve.
Background technique
In the mechanical oil recovery, faults such as fouling of sand card and gas lock often in use often take place in common employed tubing pump; Sometimes also because of thick colloidal material too much blocks standing valve, meanwhile, each oil field is often changed former oil well pump to send in passing when workover eration and is repaiied, and is fit into well with new pump or through the oil well pump of repairing again; Because of limited by mender's technical specifications, it is not good enough that most oil well pumps are repaired the back effect in repair procedures for old oil well pump, and the frequent generating pump of oil well pump of going into well after the repairing once more leaks or the pump efficiency reduction, has caused adverse effect to oil producing operation.
The model utility content
The technical problem that the utility model solved provides a kind of tubing pump that does not have the long-plunger sand control gas-tight antiscale of standing valve.
For solving above-mentioned technical problem, the technological scheme that the utility model is taked:
A kind of tubing pump that does not have the long-plunger sand control gas-tight antiscale of standing valve; Its special way is: comprise beam hanger, oil pipe, oil pump joint, heavy dirt tube, transition joint, pump barrel, plunger, oil pump box cupling; The lower end of beam hanger is connected with plunger; The outer sheathed successively from top to bottom oil pipe that is connected with each other of beam hanger, oil pump joint, heavy dirt tube, transition joint, the lower end of transition joint is connected with pump barrel, and the lower end of pump barrel connects oil pump box cupling, anti-touching short section, anti-collision box cupling, sand sediment pipe, end hoop successively; Be provided with anti-collision flower plug in the lower end endoporus of anti-touching short section, be provided with dead stifled in the lower end endoporus of end hoop; Described pump barrel is provided with the draining exhaust port.
Above-mentioned draining exhaust port is arranged on the lower end of plunger top dead center.
Compared with prior art, the beneficial effect of the utility model:
The delay polymerization of fouling composition can be effectively avoided in the increase that the utility model makes liquid go into jump degree in the process of pump, and the separation of also being convenient to the chiltern thing is sunk; No longer continue to use traditional standing valve box cupling, make mechanism's simplification under the pump, avoided the generation of pump leakage in the past or blocking phenomenon; Heavy dirt tube is set can various junks storages on this pump be avoided taking place holddown.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Referring to Fig. 1; The utility model comprises beam hanger 1, oil pipe 2, oil pump joint 3, heavy dirt tube 4, transition joint 5, pump barrel 7, plunger 8, oil pump box cupling 9; The lower end of beam hanger 1 is connected with plunger 8; The outer sheathed successively from top to bottom oil pipe that is connected with each other of beam hanger 12, oil pump joint 3, heavy dirt tube 4, transition joint 5, the lower end of transition joint 5 is connected with pump barrel 7, and the lower end of pump barrel 7 connects oil pump box cupling 9, anti-touching short section 10, anti-collision box cupling 12, sand sediment pipe 13, the end successively and binds round 14; Be provided with anti-collision flower plug 11 in the lower end endoporus of anti-touching short section 10, be provided with dead stifled 15 in the lower end endoporus of end hoop 14; Described pump barrel 7 is provided with draining exhaust port 6.
Above-mentioned draining exhaust port 6 is arranged on the lower end of plunger 8 top dead centers, and when plunger 8 went upward to specified position, draining exhaust port 6 was wished match 8 to break away from back liquid and got into thus; When plunger 8 is descending, promptly sets the Bottom Runby scope again plunger 8 is closed draining exhaust port 6.
When plunger 8 goes upward to when just surmounting draining exhaust port 6, to inhale in advance under the effect of cavity pressure difference in mineshaft annulus and plunger 8 lower ends, pit shaft liquid will pour a pump 7 fast, in pouring process, can most of chiltern thing be separated downwards, and gas is also separated thereupon; When plunger 8 is descending, nearer because of it apart from draining exhaust port 6, can rapidly it be closed, plunger 8 inner traveling valves are opened rapidly, make liquid flow into its inner chamber; When plunger 8 goes out well, can well head be proposed directly plunger 8, draining exhaust port 6 can be let out liquid in the oil pipe 2 to well, need not to install oil drainer.
