Abstract
The invention discloses a rotatable adaptive compensator of a coiled tubing test string, which comprises a locking mandrel, a compensation mandrel, a cable locking slip element and a variable buckle connector, wherein the locking mandrel is connected with the compensation mandrel by a compensation sleeve; the compensation mandrel is connected with the cable locking slip element by a cable locking sleeve; the cable locking slip element is connected with the variable buckle connector by a halter; the outer side of the locking mandrel is sleeved with a coiled tubing slip element; the lower half part of the coiled tubing slip element is sleeved with a slip element locking sleeve; a cable locking copper core is arranged in the halter; and a cable locking copper pad is placed between the cable locking copper core and the variable buckle connector. According to the compensator, a cable is fixed with the compensator by the cable locking slip element, and a bearing is used to assist the compensator in performing autorotation along with the cable, so that the cable is prevented from being divided into strands, and a purpose of protecting the cable is achieved by compensating a difference between elongations of a coiled tubing and the cable through a self-compensation structure.
Description
Technical field
The present invention relates to the oil gas water well underground operation tool, specifically a kind of coiled tubing test string can revolve adaptive compensator.
Background technology
Continuous oil pipe operation equipment is a kind of of oil field job that requires special skills equipment, and the title of " omnipotent working equipment " is arranged, and when using coiled tubing and carry out the operation of oil-water well wireline test, often runs into because coiled tubing and inside cable stretch, rotation difference causes cable to break to take off.Inapplicable this expansion loop at present, domesticly there is no coiled tubing test and can revolve adaptive compensator with the coiled tubing test string, if will cause cable to be crossed drawing damage in test jobs.
In view of this, for the problems referred to above, propose a kind of coiled tubing test string reasonable in design and that effectively improve above-mentioned disappearance and can revolve adaptive compensator.
Summary of the invention
The object of the present invention is to provide the coiled tubing test string can revolve adaptive compensator, can compatiblely connect multiple logger, can protect cable, prevent that its stretching is impaired and rotate broken strand.
In order to reach above-mentioned purpose, the invention provides the coiled tubing test string and can revolve adaptive compensator, comprise locking axle, compensation axle, cable locking slips, variable buckle joint; Described locking axle is connected by the compensation cover with the compensation axle; Described compensation axle is connected by the cable lock sleeve with cable locking slips; Described cable locking slips is connected by halter with the variable buckle joint; Described locking axle outside cover has the continuous-tube slips, and described continuous-tube slips the latter half cover has the slips lock sleeve; Described halter inside is provided with cable locking copper core, is placed with cable locking copper packing between this cable locking copper core and the variable buckle joint.
Described compensation cover and cable lock sleeve all are connected on the compensating joint in the compensation axle outside; Be provided with single thrust bearing on the compensation axle between described cable lock sleeve and the compensating joint.
Be provided with the locking shear pin that is used for fixing on described slips lock sleeve, compensation cover, cable lock sleeve, the halter.
Described cable locking copper core upper surface is provided with the aperture of the protection steel wire of interspersed cable, and this aperture is evenly arranged 24, and the outside lower end of described cable locking copper core is two sections continuous taper seats.
Described locking axle upper end outer circumference surface is taper seat.
Described continuous-tube slips upper end inner peripheral surface is taper seat, and line is cut into 6 lobes.
The inner middle-end of described cable lock sleeve is taper seat.
Outside, described cable locking slips upper end is taper seat, and line is cut into 6 lobes.
Compared to prior art, the present invention fixes cable and expansion loop by cable locking slips, uses bearing to help expansion loop to follow the cable rotation, prevents broken strand of cable; Protect simultaneously the purpose of cable with realization by the difference of self-compensating structure compensation coiled tubing and cable elongation.

The specific embodiment
Be described further with reference to the accompanying drawings:
According to shown in Figure 1; the coiled tubing test string can revolve adaptive compensator; described continuous-tube slips 2 is enclosed within on the locking axle 1 from the bottom; the bottom is threaded with slips lock sleeve 4; and fixing with locking shear pin 3; described compensation cover 5 is threaded with locking axle 1 lower end; and fix with locking shear pin; described compensation axle 6 is inserted in the compensation cover 5; contact with locking axle 1; described compensating joint 7 is inserted in compensation axle 6 and compensates in the annular space that overlaps between 5; be threaded with compensation cover 5; and fix with locking shear pin; described cable lock sleeve 9 is threaded with compensation axle 6; and fix with locking shear pin; described single thrust bearing 8 is enclosed within on the compensation axle 6; between compensating joint 7 and cable lock sleeve 9; described cable locking slips 10 is inserted in the cable lock sleeve 9 and is threaded; and fix with locking shear pin; described halter 12 tops are threaded with cable locking slips 10; and fix with locking shear pin; the bottom is threaded with variable buckle 15; and fix with locking shear pin; described cable locking copper core 13 is positioned at halter 12 inside, and places copper packing 14 between the variable buckle 15, and described cable locking copper core upper surface is provided with the aperture of the protection steel wire of interspersed cable 11; this aperture is evenly arranged 24, and the outside lower end of described cable locking copper core is two sections continuous taper seats.
Such as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, described locking axle upper end outer circumference surface is taper seat.Described continuous-tube slips upper end inner peripheral surface is taper seat, and line is cut into 6 lobes.The inner middle-end of described cable lock sleeve is taper seat.Outside, described cable locking slips upper end is taper seat, and line is cut into 6 lobes.
In the specific implementation process, cable is protected 24 strands of steel wire layerings outward, distorts in minute insertion cable locking copper core 13 upper surface apertures, again cable locking copper core 13 is inserted halters 12, and copper packing 14 connects variable buckle 15, just has been fixedly connected with cable 11.After continuous-tube slip sleeve 2 is in coiled tubing, rotation slips lock sleeve 4, it is up to promote continuous-tube slips 2, is fastened on the coiled tubing inwall, realizes connecting because the taper seat of locking axle 1 upper end opens the slips of continuous-tube slips 2.With reference to figure 1, compensation axle 6 can freely slide up and down, and epimere step and compensating joint 7 epimeres have a segment distance, has compensated the length difference that causes because coefficient of dilatation is different because of coiled tubing and cable 11.Compensation axle 6 is connected with locking axle 1 nothing, directly be connected with nothing between compensating joint 7 and the compensation cover 5, but by cable lock sleeve 9, in conjunction with single thrust bearing 8 indirect joints, guarantee the rotation self-regulation compliance that under continuous-tube pressure, produces, avoided cable 11 and coiled tubing relative torsion to cause that cable 11 damages.
The above only is preferred embodiment of the present invention, and non-in order to limit claim of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to claim of the present invention.
