Abstract
The invention relates to a winding steel strip seam sand screening pipe heating vibration device, and belongs to a device in oil field oil pumping equipment. The device consists of a center pipe, retainer rings, steel strips, steel plate strips, a resistance wire, a vibration ring and a vibration ball. For the assembly of the device, a plurality of steel plate strips are uniformly distributed on the periphery of the center pipe; each steel strip is wound on the outer surface of the corresponding steel plate strip in a way of forming certain seams; the resistance wire is wound in the space of the splayed seam of each steel strip; two pole wire heads of the resistance wire pass through an annular surface side hole of one retainer ring, so that the resistance wire is conducted with a power supply; each retainer ring inwards leans against the two ends of the wound steel strips in a penetrating and sleeving way from the two ends of the center pipe to be fixedly connected; the vibration ring is fixedly connected to a position near the two ends in the center pipe; the vibration ball is arranged in the middle space of the center pipe; and the diameter of the vibration ball is greater than the inner circle diameter of the vibration ring. The device has the advantages that the resistance to high-intensity inner pressure is realized; thickened oil is heated into liquid oil; a sand screening pipe can vibrate; seams cannot be blocked; the service life and the cleaning time are prolonged; and the fluid producing quantity is increased.
Description
Technical field: curling steel bar seam sand screen heating vibration device is belong to the device in oil-field oil pumper equipment technical field.
Background technology: known; current oil field is in oil recovery process; a kind of oil of heavy oil wells is had to be viscous crude; viscous crude has to pass through liquefy oil of heating; enter into sand screen oil pump with fluid oil could pump, because the fluid oil had contains the slot apertures that a large amount of paraffin and sand grains protect sand screen, cause the increased frequency of cleaning sand screen; affect oil recovery amount, this is the difficult problem in recovering the oil.
Summary of the invention: for solving the difficult problem in background technology, this device object is to provide one and curls steel bar seam sand screen heating vibration device, even tube wall on the central tube of this device be dispersed with several through holes, the steel plate strip of several strips at the peripheral longitudinal cloth of central tube, be provided with in the downside of steel plate strip
the open slot of shape, steel bar is triangular-section, curls in the longitudinal steel plate strip outside central tube with leg-of-mutton steel bar, and the gap curling steel bar is splay, curls resistive conductor in splay space; The two ends curling steel bar are provided with consolidation and back-up ring, the annular solid Side symmetrical of one of them back-up ring be provided with through hole, resistive conductor stretches to outside space by two through holes of back-up ring and connects with power supply; In the pipe of central tube, the inwall consolidation of vicinity, two ends oscillation ring, loads vibrating ball in central tube; This device is located in the heavy oil tested layer of heavy oil wells, because resistive conductor switches on power generation heat, makes viscous crude be liquefied as liquid state, increase oil pumping yield, and when fluid motion and an effect stopped, making vibrating ball impact oscillation ring, the vibration of oscillation ring makes sand screen produce vibration; Due to the vibration of sand screen, the sand grains protected on sand screen surface is split away off, this device for prolonging oil pumping time, anti-high-strength interior pressure, pumps 3000 meters of dark heavy oil wells, is not damaged.
The technical scheme that this device adopts: curl steel bar seam sand screen heating vibration device, formed with central tube, back-up ring, steel bar, steel plate strip, resistive conductor, oscillation ring and vibrating ball, it is characterized in that: central tube is round steel pipe, on the centre of central tube and the tube wall of vicinity thereof, through hole by even cloth, is provided with screw thread outside the two ends of central tube; Back-up ring is annular steel ring, the anchor ring side direction symmetry of one of them back-up ring be provided with through hole; Steel bar is triangular-section; Steel plate strip is elongate steel plate bar, is provided with several in steel plate strip side
shape open slot; Resistive conductor is the resistive conductor that energising produces heat; Oscillation ring is the steel body of annular, and the inner circle of oscillation ring is domatic circle; Vibrating ball is spheroidal steel body; The assembling of this device: be provided with several with the side of multiple steel plate strip
the even cloth in side of shape open slot is fastened on the periphery of central tube; Curl with steel bar on the external surface of steel plate strip according to certain gap, curl in the space in steel bar splayed gap with resistive conductor, be each passed through the anchor ring side opening of a back-up ring with the two poles of the earth the end of a thread of resistive conductor, resistive conductor and power supply are connected; Wear from the inward at both ends of central tube respectively with back-up ring and lean against the two ends consolidation curling steel bar and, in central tube, vicinity, two ends consolidation oscillation ring; Vibrating ball is enclosed in the space in the middle of in central tube, and the diameter of vibrating ball is greater than the interior circular diameter of oscillation ring.
: the gap of this device not easily blocks that anti-high-strength interior pressure, to heavy oil heating in heavy oil wells, makes viscous crude liquefy pump, and improves oil pumping yield owing to adopting the advantage of above technical scheme; Because oil pumping makes the fluid oil in sand screen move, vibrating ball is moved, the vibration of the motion impact oscillation ring of vibrating ball, makes sand screen produce vibration; The vibration of sand screen, the sand grains that sand screen surface is protected comes off, and fluid oil is entered in sand screen smoothly, extends the scavenging period of sand screen, increases Discharge rate.
