Abstract
The invention relates to an eccentric wear prevention test system for a coupling, which is applied to an oil well. The eccentric wear prevention test system for the coupling comprises an oil tank, wherein two pulleys are arranged at the bottom of the oil tank; a compaction device is arranged at the upper part of the midpoint connecting line of the two pulleys; a clamping buckle is arranged at the lower part of the compaction device; a pushing device is arranged outside the oil tank. The eccentric wear prevention test system for the coupling is simple in connection structure and good in test effect.
Description
Technical field
The present invention relates to the experimental system of the anti-eccentric wear of box cupling for a kind of oil well.
Background technology
Along with oil field enters high water-cut development period, oil well condition is harsher, and side-abrasion of rod string problem is more outstanding, causes oil pipe leakage, the de-disconnected phenomenon of sucker rod constantly to increase.Out-of-shape and the outside dimension of sucker-rod coupling are larger, easily contact with oil pipe, so the serious point of eccentric wear problem is all at box cupling place.For side-abrasion of rod string phenomenon, the improvement that staff carries out, but neither one efficient system is evaluated improving the anti-eccentric wear of rear equipment.
Summary of the invention
The invention provides a kind of pilot system that can evaluate anti-bias wearing joint hoop effect.
Anti-bias wearing joint hoop pilot system of the present invention, comprises fuel tank, and fuel tank bottom is provided with two pulleys, and two pulleys divide and are arranged, and the top of two pulley mid point connecting lines is provided with hold down gag, and the bottom of hold down gag is provided with buckle, and fuel tank is provided with pusher.
Preferably, described hold down gag comprises clamping motor and hydraulic cylinder, and described buckle is fixed on the piston rod of hydraulic cylinder.
Preferably, described pusher comprises motor, reductor and connecting rod, and described motor, reductor is connected successively with connecting rod, and a part for described connecting rod is goed deep among fuel tank.
Anti-bias wearing joint hoop pilot system of the present invention, syndeton is simple, good test effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-fuel tank in figure; 2-pulley; 3-clamping motor; 4-hydraulic cylinder; 5-motor; 6-connecting rod.
Embodiment
Anti-bias wearing joint hoop pilot system of the present invention, comprise fuel tank 1, fuel tank 1 bottom is provided with two pulleys 2, two pulleys 2 minutes are arranged, and the top of two pulley 2 mid point connecting lines is provided with hold down gag, this hold down gag comprises clamping motor 3 and hydraulic cylinder 4, and described buckle is fixed on the piston rod of hydraulic cylinder 4.Described pusher comprises motor 5, reductor and connecting rod 6, and described motor 5, reductor is connected successively with connecting rod 6, and a part for described connecting rod 6 is goed deep among fuel tank 1.During use by box cupling cleave in two, get that wherein half is placed on oil pipe, and fixed by snap on hydraulic cylinder 4 piston rods, by clamping motor 3, box cupling is pressed on oil pipe, oil pipe is arranged on pulley 2 Shang， one end and is fixed on connecting rod 6, and motor 5 provides power, drivening rod 6 and oil pipe move back and forth successively, the test of the anti-eccentric wear effect of the hoop that achieves a butt joint.
