Abstract
The utility model relates to a screw suspension support type polish rod for pumping oil well which is an oil extraction machine and is formed by the connection of protection threads on the upper end of a screw rod, a regulating nut, a suspension rope implement, a screw rod, a polish rod and an unloading support pipe. The protection threads on the upper end of the screw rod is on the top of the screw rod, the regulating nut is sheathed in the screw rod, and the suspension rope implement is at the lower side of the regulating nut. The polish rod is at the lower side of the screw rod, the unloading support pipe is installed on the lower end of the polish rod, and the lower end of the unloading support pipe is connected with a blowout preventing box. The apparatus has the advantages of big load quantity, strong tensile stress, easy and simple operation, corrosion prevention, collision prevention and anti-reverse.
Description
One, technical field: novel a kind of oil recovery machiner, especially the pumpingh well screw thread suspension strut formula polished rod of relating to of this use.
Two, background technology: polished rod is the solid steel pole that pumpingh well is connected the rod string top, and it is connected with the polished rod eye of oil pumper by the square clamp of top polished rod, and the bottom is connected with the oil pumping pole band.Polished rod plays and hangs sucker rod and above liquid strain and other load of oil well pump in the pumpingh well, plays a part to transmit oil pumper power simultaneously.Polished rod is the part of bearing load maximum in the sucker rod.
For these years, pumpingh well is continued to use the hang of card side's clamp on the polished rod always both at home and abroad, in production practices for many years, its defective progressively manifests, main performance: the one, waste time and energy, when implementing the operations such as unloaded of oil well measure, need 2-3 people, by the side's of unloading clamp screw on the pipe wrench (spanner) of large size, unload the screw of 2-3 square clamp on each, seriously wasted manpower and time; The 2nd, safety factor is low, occurs the clamp slippage of well head side sometimes and pounds the accident that disconnected workman's hand is disabled, and the square clamp slippage on the polished rod eye then causes polished rod, the beam hanger well that falls to stop production; Last when unloading above the polished rod eye square clamp, also, excessive, spanner firmly throws the phenomenon of causing injury from the high-altitude because of skidding; The 3rd, increase the oil well production cost, be the side's of preventing clamp slippage polished rod well that falls, most pumpingh wells adopt two square clamps to hang, and will scrap with twice at most.The square clamp slips that load removal is used also can be bad through the surface of specially treated card polished rod, and some production fluids have the oil well of corrosion, the polished rod of breakage corroded again increase the weight of, and not only influences the life-span of polished rod, also reduced the service time of blowout prevention box sealed packing; The 4th, rate when having reduced oil well production, there is slippage to break during owing to polished rod and causes salvaging or well workover (well workover needs about 200,000 yuan), not only increased the cost of production of oil well, rate when also greatly reducing the production of oil well, even when measures such as transferring ginseng is constructed, because of on the side's of unloading clamp equal time long, cured card, sand card, salt card also appear often and cause stopping production, the phenomenon of well workover.
Three, summary of the invention: the novel pumpingh well screw thread suspension strut formula polished rod that provides of this use, the oil production technology of screw thread suspension strut formula polished rod has kept the advantage of former polished rod production technology, has overcome defective such as waste time and energy, unsafe factor, cost are high and rate is low when producing.This technology is taked polished rod top rammer (adding) rough turn button; hang polished rod and following lotus and the adjusting polished rod technology up and down of planting with adjusting nut; take the method for off-load stay pipe unloaded; and designed integral body, split, multiple model such as can connect, the screw thread suspension type polished rod of plurality of specifications; is furnished with adjusting nut; the damping reverse fixation preventing device, off-load stay pipe and protecting sleeve for thread etc.The purpose of this utility model is achieved in that it is to be formed by connecting by threaded rod upper end thread protector, adjusting nut, polished rod eye, threaded rod, polished rod, off-load stay pipe, and threaded rod upper end thread protector is positioned at the threaded rod top; Adjusting nut is enclosed within on the threaded rod; Polished rod eye be positioned at adjusting nut below; Polished rod be positioned at threaded rod below; The off-load stay pipe is installed in the lower end of polished rod; The lower end of off-load stay pipe is connecting the blowout prevention box.
Polished rod has three kinds of forms, and a kind of is the whole polished rod of two jumping-up type screw thread suspension type, and the polished rod two ends are threaded rod jumping-up heads; Second kind is the whole polished rod of middle jumping-up type screw thread suspension type, is middle jumping-up threaded rod in the middle of the polished rod, and the lower end of polished rod is a polished rod jumping-up head; The third is two jumping-up type screw thread suspension type split polished rod, and it is to be formed by connecting by split screw rod, thread, polished rod, polished rod jumping-up head.The split screw rod is connected with polished rod by thread, and an end of polished rod is a polished rod jumping-up head.
The off-load stay pipe by hexagonal be inserted in packing gland cover for seat, pillar, stay pipe turnover polished rod opening, retaining ring locating piece, middle retaining ring, stay pipe, the pillar groove is formed by connecting, protective pipe sleeve is on stay pipe; The retaining ring locating piece is welded on the stay pipe; Middle retaining ring is enclosed within on the stay pipe; Stay pipe turnover polished rod opening is arranged in the middle of the stay pipe; One end of pillar is the pillar groove.
Advantages such as this device has that load capacity is big, tension stress is strong, easy and simple to handle, corrosion-resistant, anticollision, anti-back-off.
