Abstract
The invention discloses a sand screening tube vibration device with a gear-shaped net barrel made of stainless steel plates, and belongs to devices of oilfield equipment. The sand screening tube vibration device comprises a center tube, end hoops, a net protective barrel, the gear-shaped net barrel made of the stainless steel plates, vibration rings and vibration balls. The gear-shaped net barrel made of the stainless steel plates sleeves the outer circle of the center tube, the net protective barrel sleeves the outer circle of the gear-shaped net barrel made of the stainless steel plates, L-shaped circular pits of the end hoops are fastened at two ends of the net protective barrel, the end hoops are fixed onto outer circles near two ends of the center tube, outer circles of the vibration rings are fixed onto the tube walls at the inner upper ends of the center tube, the vibration balls are arranged in spaces at the inner upper ends of the center tube, and the diameters of inner circles of the vibration rings are smaller than those of outer circles of the vibration balls. The sand screening tube vibration device has the advantages that the vibration balls can move upwardly under the effect of upward movement of oil and can fall back into holes in the inner circles of the vibration rings when the oil intermittently stops moving; the vibration rings are stricken by the vibration balls, sand screening tubes can vibrate, accordingly, sand protected by the net barrel made of the stainless steel plates can fall off, seam holes of the net barrel are difficult to block, the liquid production periods can be prolonged, and the liquid production quantities can be increased.
Description
Technical field: gear shape stainless steel plate mesh cylinder sand screen vibrating device belongs to the device in oil-field oil pumper equipment technical field.
Background technology: known, current oil field is in oil pumping operation, and the slot apertures of sand screen is easily blocked, particularly patent No. ZL2005201434127, title: gear shape stainless steel plate mesh cylinder sand filtering tube device.Sand grains protects and stays in the slot apertures of stainless steel plate mesh, is difficult to come off, and causes stainless steel plate mesh slot apertures to block, affects oil pumping yield, and this is a difficult problem for oil producing operation.
Summary of the invention: for solving the difficult problem in background technology, this device object is to provide a kind of gear shape stainless steel plate mesh cylinder sand screen vibrating device, on the centre of the central tube of this device and the tube wall of vicinity, even cloth arranges several through holes, gear shape stainless steel plate mesh cylinder is set on the cylindrical of central tube, protecting wire net jacket casing is in the periphery of gear shape stainless steel plate mesh cylinder, the L shape annulus nest of termination hoop is fastened on the two ends of protecting wire net cylinder, termination hoop is cemented in the vicinity, two ends of central tube, the cylindrical of oscillation ring is cemented in tube wall vicinity in upper end in central tube, vibrating ball is enclosed in the space of central tube upper end, this device is in oil pumping process, because vibrating ball is mentioned by moving upward of fluid, stopping time when between fluid, vibrating ball impact shock ring, sand screen is made to produce vibration, so the sand grains protected on sand screen is come off down by vibration, the gear shape stainless steel plate mesh cylinder slot apertures of this device not easily blocks, extend the service time of cleaning sand screen, increase Discharge rate.
The technical scheme that this device adopts, gear shape stainless steel plate mesh cylinder sand screen vibrating device, formed with central tube, termination hoop, protecting wire net cylinder, gear shape stainless steel plate mesh cylinder, oscillation ring and vibrating ball, it is characterized in that central tube is round steel pipe, on the centre of steel pipe and the tube wall of vicinity, even cloth arranges several through holes, and the two ends of central tube are provided with external screw thread; Termination hoop is annular steel body, is domatic circle, is provided with L shape ring nest in the opposite side of annular steel body in the side of annular steel body; Protecting wire net cylinder is cylindrical shape steel mesh cylinder; Gear shape stainless steel plate mesh cylinder is that corrosion resistant plate makes gear-shaped web clothed cylinder; Oscillation ring is annular steel body, and its inner circle is groove circle; Vibrating ball is spheroidal steel body; The assembling of this device: the periphery being set on central tube with gear shape stainless steel plate mesh cylinder, with protecting wire net jacket casing on the cylindrical of gear shape stainless steel plate mesh cylinder, the two ends of protecting wire net cylinder are fastened on the L shape circle nest of termination hoop, termination hoop is cemented on the cylindrical of vicinity, central tube two ends, the cylindrical of oscillation ring is cemented on the tube wall of upper end in central tube, vibrating ball is enclosed in the upper end space in central tube, and in oscillation ring, diameter of a circle is less than vibrating ball outside diameter.
Owing to adopting the advantage of above technical scheme be: in oil pumping process, fluid in the central tube of this device motion and stop act on, vibrating ball risen and whereabouts, drop under vibrating ball in the centre bore of oscillation ring, impact oscillation ring, sand screen is vibrated; The vibration of sand screen, make to protect the sand grains stayed in gear shape stainless steel plate mesh cylinder slot apertures and come off down, the slot apertures of stainless steel plate mesh cylinder not easily blocks, and extends sand screen in down-hole service time, increases Discharge rate.
