Simple operation, convenient use and strong practicability.
Description
Technical field
The utility model belongs to oil development technical field, relates to a kind of pumping well downhole tool, specifically a kind of oil pump antiscale card column plug.
Background technique
At present, each oilfield pumping well prevents the method for dirt card from being down-hole application long-plunger short pump barrel antiscale pump apparatus, and ground well head adds boiler compound to oil jacket annular space; But the plunger surface of long-plunger short pump barrel antiscale pump and not enter the fouling of pump barrel part serious, often there is plunger stuck phenomenon, affect production time efficiency, fouling peak period pump detection period was less than 75 days, have impact on development effectiveness, it is undesirable to there is antiscaling effect in therefore traditional equipment, and makes field personnel's work load large, the problems such as operating process very complicated.
Summary of the invention
In order to solve traditional equipment, to there is antiscaling effect undesirable, and make staff's work load large, the problem of operating process very complicated, the utility model proposes a kind of when not taking to add boiler compound, improve oil well pump antiscale card adaptability, realize the plunger that fixed tubular column just can realize changing antiscale card, its concrete technological scheme is as follows:
A kind of oil pump antiscale card column plug, comprise the upper connection that right-hand member is connected with underground sucker rod, described upper connection right-hand member has transverse passageway, and upper connection right-hand member is provided with outside thread; Also comprise center-pole, described center-pole one end is placed in described transverse passageway, and the other end is provided with boss, and described center-pole is connected with slotted nut, and slotted nut is threaded with upper connection right-hand member by its internal thread be provided with; Center-pole stage casing is from left to right socketed with the upper sliding sleeve of ring-type, packing element and low sleeve successively.
The distortion ring cavity of ring-type is had inside described packing element.
Described slotted nut outer surface evenly has three nut liquid outlet grooves.
Described center-pole outer surface evenly has three center-pole liquid outlet grooves.
The beneficial effects of the utility model: be arranged on when this instrument is used in pumping well on underground sucker rod, in the pumping unit upstroke stage, oil well pump standing valve is opened, sucker rod is up, on the upper sliding sleeve that pressure is applied to instrument and packing element, packing element is extruded distortion thus distending, and then realizes scraping dirt; In the down stroke stage, standing valve is closed, and sucker rod is descending, and center-pole boss and low sleeve are thrown off and lost sealing, packing element pressure release withdrawal; If there is the damage of plunger packing element need not move tubing string and replaceable plunger, when this plunger coordinates with boiler compound, effectively antiscale can be carried out; Simple to operate, easy to use and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-upper connection, 2-transverse passageway, 3-center-pole, 4-boss, 5-slotted nut, 6-upper sliding sleeve, 7-packing element, 8-low sleeve, 9-is out of shape ring cavity, 10-center-pole liquid outlet groove.
Embodiment
For the ease of understanding, below in conjunction with Fig. 1, the utility model is further illustrated:
Embodiment 1: a kind of oil pump antiscale card column plug, comprising the upper connection 1 that right-hand member is connected with underground sucker rod, for being connected with sucker rod, and then making it vertically move in well with sucker rod; Described upper connection 1 right-hand member has transverse passageway 2, and upper connection 1 right-hand member is provided with outside thread, and transverse passageway 2 is for holding the termination, right side of center-pole 3, and outside thread is used for it to be connected with upper connection 1; Also comprise center-pole 3, described center-pole 3 one end is placed in described transverse passageway 2, and the other end is provided with boss 4, and boss 4, for blocking the equipment of socket on center-pole 31, bears extruding force; Described center-pole 3 is connected with slotted nut 5, and slotted nut 5 is threaded with upper connection 1 right-hand member by its internal thread be provided with; Center-pole 3 stage casing is from left to right socketed with the upper sliding sleeve 6 of ring-type, packing element 7 and low sleeve 8 successively, when upper sliding sleeve 6 or low sleeve are under pressure, slide to center-pole 3 one end, and then extruded, packing element 7 is out of shape, so that realize scraping dirt, when wherein sucker rod moves down, low sleeve 8 is stressed, and when sucker rod moves, upper sliding sleeve 6 is stressed.
Embodiment 2: in order to better realize antiscaling effect, have the distortion ring cavity 9 of ring-type inside described packing element 7, so that packing element 7 is easier to distortion thus strengthens antiscaling effect.
Embodiment 3: further, in order to make device can with boiler compound with the use of, described slotted nut 5 outer surface evenly has three nut liquid outlet grooves, so that the outflow of boiler compound.
Embodiment 4: further, in order to make device can with scale remover with the use of, described center-pole 3 outer surface evenly has three center-pole liquid outlet grooves 10, so that the outflow of boiler compound.
Beneficial effect: simple to operate, easy to use and practical; Effectively solving legacy equipment, to there is antiscaling effect undesirable, and make staff's work load large, the problem of operating process very complicated.
