Three annular axial sand settling channels are arranged on the sand setting device and lead to a sand setting tail pipe, so that sand burying can be prevented, the sand blocking device can filter large sand grains in pump liquid to sink into the bottom of a well, a pump is not buried, and oil well production is guaranteed.
Description
Technical field:
The utility model relates to a kind of long-plunger oil well pump of anti-sand, belongs to pumping unit downhole tool class.
Background technique:
In oilfield exploitation, there are many sand productions serious, some wells are because of the incompatible exploitation benefit that can't pumping restricting the oil field of the serious common oil well pump that shakes out.Although studied multiple sand-proof oil-well pump at the big well of sand content.Because of being still far from perfect, its structure still exists certain narrow limitation, can't solve sand and bury problem, cause the oil well operation frequent, the cost for oil production height, oil well pump pump leakage etc. occurred by the sand card, in addition, existing oil well pump structure lacks the pump fluid filtering device and can't solve after the particle diameter sand grains close with the pump gap enters the pump gap and cause oil well pump generation hard card and wear problem, more can't intercept the difficult problem that sand grains greatly enters tubing string.
The model utility content:
The utility model purpose: in order to overcome above-mentioned shortcoming, and a kind of long-plunger oil well pump of anti-sand that provides, this oil well pump can reduce the oil well operation in containing the big oil well of sand, realizes that in the oil well that generally shakes out retaining, heavy, sediment outflow and lost circulation prevention are in one.
The utility model is to realize like this;
It an oil well pump by the screwed connection of multifunction pump joint bottom, and sand setting device and sand-baffling device three parts constitute.Described oil well pump is made up of standing part and active part.Standing part is linking preposition centralizer with screw thread from top to bottom successively, short pump barrel, the multifunction pump box cupling in the short pump barrel lower end with screwed connection, the lengthening pump line in the pump barrel in screw thread and the pump barrel, dimensionally stable joint, and lengthening pump line lower end uses screwed connection, twin-stage standing valve assembly, active part are in pump housing joint, from top to bottom are equipped with successively and put joint, reach upper traveling valve cage, upper travelling valve and tail cap are housed in the valve bonnet that moves about with screwed connection.Described sand setting device is by sand setting urceolus of interior screwed connection in multi-functional pump housing head lower end, and with special-shaped box cupling of screwed connection with at special-shaped box cupling internal layer and the feed liquor sand setting shunt that reaches standing valve assembly lower end, the sand setting tail pipe is equipped with in the shunt lower end.
Described sand-baffling device mainly by the sand setting urceolus with screwed connection.The abnormity box cupling is equipped with stainless steel mesh under abnormal shape connects sieve, screen cloth has protective housing outward, and chimney filter is set upright joint.Described feed liquor sand setting shunt has three radially feed liquor duct and three sand setting ducts.
The utility model compared with prior art has a significant effect:
The utility model is because the pumping fluid filtrating equipment has been gone in tipping makes it have sand control card function also to have the sand setting sand block function that does not possess in the existing technology.Sand setting device and sand-baffling device in oil well pump, the sand that can come avaling in the oil pump tubular column on the oil well pump sink under the pump in the tail pipe, oil well pump is not buried by sand, the big sand grains that guarantees oil well pump is blocked in outside the pump, therefore say that this pump is the sand-proof oil-well pump that a collection retaining, heavy, sediment outflow and lost circulation prevention give one, be specially adapted to a pump heating organic bar one pump sand control system of institute in addition and also can prolong the oil well pump manufacture cycle, improved the oil mining benefit.

Embodiment:
The utility model is provided by following examples, does into step description down below in conjunction with accompanying drawing.
Form by oil well pump, sand setting device and sand block three parts among the figure.
The described oil well pump of Fig. 1 is a secondary standing valve plunger body and each connection piece up and down is same tolerance of size, be divided into its standing part, preposition centralizer 7, short pump barrel 9, multifunction pump socket joint hoop 11, lengthening pump line 14, dimensionally stable joint 15 with screwed connection successively from top to bottom, (Fig. 2) twin-stage standing valve assembly 16, active part (Fig. 1) upper connection 2, upper traveling valve cage 3, upper travelling valve 4, discharge outlet 5, lengthening plunger body 8, lower travelling valve cover 10, lower travelling valve 12, tail cap 13 by screwed connection from top to bottom.
This device working principle is identical with common oil well pump, the effect of twin-stage standing valve is to reduce the leakage that contains the sand drain valve, long-plunger can make the upper end of pump barrel 8 be in all the time under the valve bonnet 3 that moves about, and can prevent that the sand grains in the oil pump tubular column from sinking in the pump barrel, thereby avoids sand card accident to take place.
Sand setting device part is linking multi-functional pump housing joint 1 successively by the oil pipe screw thread from top to bottom, sand setting urceolus 6, special-shaped box cupling 17, (Fig. 2) oil-feed sand setting shunt 18, sand setting tail pipe 21, three radially feed liquor duct and three ring shaped axial sand setting ducts are arranged in feed liquor sand setting shunt 18, described three feed liquor ducts communicate with the oil well pump standing valve, three ring shaped axial sand setting ducts can be with the next sand that avales in the oil pump tubular column through sand setting urceolus 6 and short pump barrel 8, annular pass between the lengthening pump line 14 is guided in the sand setting tail pipe, buries the oil well pump phenomenon thereby prevent sand.Be arranged on the outer sand-baffling device of sand setting shunt and set upright joint 22 usefulness screw threads by special-shaped box cupling 17, stainless steel mesh 19, protective housing 20, chimney filter and connect together, the big footpath sand grains in the pump liquid can be filtered, make it sink to the shaft bottom, that has reduced sand advances the pump amount.
