Abstract
The invention relates to an oil production wellhead device capable of rotating automatically. The oil production wellhead device capable of rotating automatically is formed by sequentially assembling a large four way, a worm gear rotating body, plane bearings, steal balls, rubber sealing rings and a hanging device, wherein the large four way is a carrier of the device, and is provided with a worm hole, plane bearing blocks and steel ball grooves; and the worm gear rotating body is positioned on the plane bearings of the large four way; the hanging device is arranged in an inner conical bore of the worm gear rotating body; and an oil pipe is arranged on the lower part of the inner bore of the hanging device. Under the condition that external power is not added, a rotating device is driven by upward stroke and downward stroke of a polished rod to automatically rotate an oil pipe column, so that the contacting positions of a sucker rod column and the inner bore of the oil pipe are changed in time, the inner wall of the oil pipe is uniformly abraded, the service life of the oil pipe is greatly prolonged, the operation times are reduced, crude oil yield is improved, and the oil extraction cost is lowered.
Description
Technical field
The present invention relates to the used wellhead for production in oil recovery field, oil field, especially rotate wellhead for production.
Background technology
In the oil recovery field, wellhead for production is the visual plant that recovers the oil.Wellhead for production mainly contains concentric wellhead for production and eccentric wellhead for production.Decentralized wellhead mainly is to solve to recover the oil and test problem, and tubing string has certain eccentric throw in the down-hole, thereby realizes annulus logging through the rotation well head.And production wellhead is generally non-rotatable with one heart; If rod string and oil pipe decentraction then cause the wearing and tearing of rod string and oil pipe easily; Because tubing string is non-rotatable, therefore very easily cause the local eccentric wear of oil pipe, the time one is long; Cause oil pipe to lose efficacy easily, thereby directly influence the production of oil well.
Summary of the invention
In order to overcome the above-mentioned defective of existing concentric wellhead assembly, the present invention provides a kind of rotation wellhead for production, and this rotation wellhead assembly not only can rotate, and has simple in structurely, and bearing capacity is high, the characteristics of long service life, saving cost for oil production.
The technical solution adopted for the present invention to solve the technical problems is: rotate wellhead for production automatically and formed by big four, worm gear rotary body, plane bearing, steel ball, rubber seal, the orderly installation of hanger; Big four is the carrier of this device, is processed with worm hole on it, the planar axes bearing; The steel ball groove; The worm gear rotary body just is located on the planar axes bearing of big four, in the female cone hole of worm gear rotary body, hanger is installed, and oil pipe is installed in the endoporus of hanger bottom.Said worm gear rotary body, its cylindrical top machining worm wheel, middle part processing plane bearing support, bottom machined steel ball impression groove, rubber seal groove, rounding platform hole is processed on endoporus top, bottom processing trapezoidal thread.Said hanger; Its external process becomes reverse frustoconic; Copper bar is applied in the shop, middle part; Bottom processing trapezoidal thread, each processing
oil pipe internal thread fuel feed pump of endoporus upper and lower is installed, and 2-φ 12-20 fabrication hole is bored at the top.
The invention has the beneficial effects as follows: under the situation that does not increase external power; Can pass through the automatic rotation pipeline post of polished rod up-down stroke driven rotary device, thereby make rod string and the timely conversion contact position of oil pipe endoporus, tube inner wall is worn and torn uniformly; Prolonged the application life of oil pipe greatly; Reduce the operation number of times, improve crude output, reduce cost for oil production.Simultaneously, can on the basis of existing big four, undergo technological transformation, help workload and saving cost that saving technique is transformed.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structure principle chart of the present invention.
Fig. 2 is the vertical view of structure principle chart of the present invention.
In the drawings: 1, big four, 2, the worm gear rotary body, 3, hanger, 4, worm screw, 5, copper bar, 6, plane bearing, 7, steel ball, 8, the shutoff screw, 9, rubber seal, 10, tubing string, 11, worm bearing, 12, click, 13, connecting rod.
The specific embodiment
In Fig. 1, through machining with big four 1, worm gear rotary body 2, hanger 3, worm screw 4 processing is qualified.Big four is as the carrier of this device, and planar axes 6 is equipped with in the hole within it, as the load-bearing and the rotation of tubing string 10, hanger 3, worm gear rotary body 2.For preventing the recoil of tubing string, the steel ball of in rotary body bottom and big four circular groove, packing into, the shutoff screw 8 of screwing on after steel ball 7 is filled at underground oil and gas pressure.Hanger 3 is installed in the endoporus of rotary body 2, and the bottom is processed with trapezoidal thread, is drilled with 2-φ 12-20 fabrication hole at the top of hanger 3, supplies special tool to be inserted in the interior trapezoidal thread with hanger 3 screw-in rotary bodies of fabrication hole, prevents the recoil when down-hole air pressure is too high.On big four 1, load onto worm screw 4 and click 12, worm bearing 11 coincide with the worm gear rotary body, refills connecting rod 13.Polished rod eye on connecting rod 13 and the polished rod with flexible strap link to each other, polished rod eye every toward upstroke once just drivening rod clockwise rotate an angle; Because click 12 devices are arranged; Worm screw 4 only can clockwise rotate, oil pumper continuous operation, just driven rotary wellhead assembly rotation of worm screw 4; Thereby change the relative position of rod string and tube inner wall at any time, reach the uniform wear of rod string and oil pipe.
