Abstract
The utility model provides a novel oil-well pump plunger, includes the lower valve subassembly, the lower valve cover and the lower valve silk of pressing which characterized in that: the lower Vera wire pressing is lengthened, a section of blank cutter is processed on the lengthening section, an oil inlet hole is formed in the part of the blank cutter section, a spiral groove is processed in the unprocessed blank cutter section below the oil inlet hole and used for filtering gravel in oil, and an oil outlet end in the upper part of the spiral groove corresponds to the oil inlet hole. By using the sand-proof oil well pump plunger of the utility model, the spiral groove is correspondingly processed below the oil inlet, so that the oil liquid entering the oil inlet becomes the rotary oil flow, and the gravel in the oil liquid is separated out under the action of centrifugal force, thereby preventing the gravel in the oil liquid from entering the oil well pump plunger; meanwhile, due to the spiral groove structure on the plunger of the oil well pump, when the oil well pump works normally, oil acting on the spiral line can generate a left-handed tangential force, so that the plunger of the oil well pump and the sucker rod system which are all in left-handed threaded connection are always in a fastening state, the threads at the joint part of the sucker rod can be prevented from loosening, and the oil well pump is safe and reliable.
Description
Technical Field
The utility model belongs to the technical field of the oil machinery, especially, relate to an oil-well pump plunger that oil field oil recovery was used.
Background
At present, the plunger of the pump directly enters liquid from a circular hole at the bottom of a valve assembly below the plunger, and the oil always contains some gravels. In the oil pumping process, gravel can get into the oil-well pump barrel along with fluid, and gravel content is too much in fluid, just causes the card pump easily, influences the oil field and normally recovers the oil operation.
Disclosure of Invention
The utility model aims at providing a unique structure, reliable and stable's sand control oil-well pump plunger.
In order to achieve the above object, the utility model provides a novel oil well pump plunger, press the silk including lower valve subassembly, lower valve cover and lower valve, its characterized in that: the lower Vera wire pressing is lengthened, a section of blank cutter is processed on the lengthening section, an oil inlet hole is formed in the part of the blank cutter section, a spiral groove is processed in the unprocessed blank cutter section below the oil inlet hole and used for filtering gravel in oil, and an oil outlet end in the upper part of the spiral groove corresponds to the oil inlet hole. During oil pumping, the oil liquid forms a rotary flowing state from bottom to top through the spiral groove, under the action of centrifugal force, gravel in the oil liquid is separated out, and the oil liquid after the gravel is separated out enters the plunger of the oil well pump from the oil inlet hole of the empty cutter section. Meanwhile, due to the spiral groove structure of the plunger of the oil well pump, when the oil well pump works normally, oil acting on the spiral line of the spiral groove can generate a rotating tangential force, so that the plunger of the oil well pump and the sucker rod system are always in a fastening state, and the loosening of the thread at the joint part of the sucker rod can be prevented.
Three spiral grooves are uniformly distributed, the gap is 16.5mm, the width of each spiral groove is 26.5mm, and the length of each spiral groove is 60 mm.
The oil inlet is 3 oblong holes which are uniformly distributed on the plunger, the width of the oil inlet is 12mm, and the length of the oil inlet is 40 mm.
The radial depth of the blank part is 3 mm.
The oil outlet end at the upper part of the spiral groove is 5mm away from the lower part of the oil inlet hole.
The utility model discloses the oil-well pump plunger when oil-well pump plunger work is down, fluid goes upward in helicla flute and inlet port entering oil-well pump plunger, and when the oil-well pump plunger went upward, the lower valve of oil-well pump plunger was closed, and the oil-well pump realizes the pump oil work.
The utility model has the advantages that: by using the sand-proof oil well pump plunger of the utility model, the spiral groove is correspondingly processed below the oil inlet, so that the oil liquid entering the oil inlet becomes the rotary oil flow, and the gravel in the oil liquid is separated out under the action of centrifugal force, thereby preventing the gravel in the oil liquid from entering the oil well pump plunger; meanwhile, due to the spiral groove structure on the plunger of the oil well pump, when the oil well pump works normally, oil acting on the spiral line can generate a left-handed tangential force, so that the plunger of the oil well pump and the sucker rod system which are all in left-handed threaded connection are always in a fastening state, the threads at the joint part of the sucker rod can be prevented from loosening, and the oil well pump is safe and reliable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the embodiment of the present invention is that a lower valve assembly 3 of the oil pump plunger is installed inside a lower valve cover 2 of the oil pump plunger, and a lower valve pressing wire 1 is arranged on the lower portion of the lower valve assembly of the oil pump plunger to press the valve assembly. The lower valve pressing wire 1 is lengthened, a section of hollow cutter is processed on the lengthened section, a long circular hole 4 is formed in the position of the hollow cutter section and used for oil feeding, a spiral groove 5 is processed on the wall of the plunger piston below the long circular hole of the unprocessed hollow cutter section and used for liquid passing, the oil liquid can form a rotary flowing state before entering the plunger piston of the oil well pump under the action of the spiral groove, gravel in the oil liquid is separated out under the action of centrifugal force and does not enter the oil feeding long circular hole. Meanwhile, due to the spiral structure of the plunger of the oil well pump, the plunger of the oil well pump and the sucker rod system can be always in a fastening state when the oil well pump works normally, and the loosening of the threads at the joint part of the sucker rod can be prevented.
