When carrying out shackle, first utilizing the clamping back tongs of continuous circulation device to clamp drilling rod, in utilization, shackle oil cylinder carries out shackle, starts spinner motor spinner simultaneously, if screw thread can normally be unloaded out, then shackle completes; As shackle can not be carried out, then go up shackle oil cylinder to remain to starting position and be failure to actuate, but the buckle press that unloads of oil cylinder can be very high, when upper shackle oil cylinder keeps initial high pressure break-out torque, the shackle function starting top driving device carries out shackle, then acting on the moment of torsion unloading buckle joint is that the break-out torque 40KN.m that break-out torque B is superimposed with continuous circulation device is driven on top, i.e. (B+40) KN.m, and push up and drive between drilling rod or moment of torsion between thribble drilling rod and drilling rod is only BKN.m, much smaller than the moment of torsion suffered by shackle joint, other joints can not be caused to thread off.When spinner motor encoder detects motion, proving that button unloads out, superposition shackle function stop is driven on top, utilizes spinner motor spinner simultaneously, completes shackle function.
A kind of top is driven the continuous circulation device of moment of torsion superposition, containing upper shackle oil cylinder, spinner motor, clamping back tongs, blind rams, the first half envelope flashboard and balance mechanism, the 2 half envelope flashboards;
On two upper shackle oil cylinders, four spinner motors and the four balancing cylinders pedestal being connected to main frame power jaw mechanism by uniform symmetries such as bolts, the major parts that the first half envelope flashboards, blind rams, clamping back tongs and the 2 half envelope flashboard realize continuous circulatory function as main frame is arranged on complete machine pedestal central authorities between two parties. Power jaw mechanism is connected together by balancing cylinder with complete machine pedestal.
It is an advantage of the invention that the method for the upper shackle process of the continuous circulation device that is added to, makes the upper break-out torque of continuous circulation device reach a maximum value by being set by certain condition by the upper break-out torque of top driving device, thus reach on-the-spot service requirements.
The present invention provides a kind of upper shackle method of moment of torsion superposition, solves the problem of break-out torque scarce capacity on continuous circulation device, for the successful Application of continuous circulation device is laid a good foundation.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more complete can understand the present invention better and easily learn wherein many adjoint advantages, but accompanying drawing described herein is used to provide a further understanding of the present invention, form the part of the present invention, the schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention, as schemed wherein:
Fig. 1 is the structural representation of the present invention.
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on the objective of the present invention belong to protection scope of the present invention.
Embodiment 1: as shown in Figure 1, a kind of top is driven the continuous circulation device of moment of torsion superposition, upper shackle oil cylinder 1, spinner motor 2, clamping back tongs 6, blind rams 5, the first half envelope flashboard 3 and balance mechanism the 4, the 2 half envelope flashboard 7, power jaw mechanism pedestal 8, complete machine pedestals 9;
Two upper shackle oil cylinder 1, four spinner motors 2 and four balancing cylinders 4 are by the pedestal 8 being connected to main frame power jaw mechanism of the uniform symmetries such as bolt, and the major parts that the first half envelope flashboards 3, blind rams 5, clamping back tongs the 6 and the 2 half envelope flashboard 7 realize continuous circulatory function as main frame is arranged on complete machine pedestal 9 central authorities between two parties. Power jaw mechanism is connected together by balancing cylinder with complete machine pedestal.
The present invention is applicable to the compression and decompression of continuous circulation device. The object of upper shackle is reached by the continuous circulation device that is added to by the compression and decompression moment of torsion of top driving device. Continuous circulation device shut shackle structure mutually as shown in Figure 1, comprising: upper shackle oil cylinder, spinner motor, clamping back tongs, blind rams, half envelope flashboard and balance mechanism, power jaw mechanism pedestal, complete machine pedestal etc. Continuous circulation device itself is up to about 40KN.m without the test clamping moment of shackle in dental impression, drive and general 5 for conventional DQ70BSC top below " drilling rod; what the method was described realizes process, and DQ70BSC pushes up the torque wrench moment 50KN.m driven, and maximum break-out torque is 75KN.m.
Upper button process:
During torque wrench moment A < 50KN.m, utilizing and detain on top driving device, namely the clamping back tongs of circulation device clamps drill pipe sub continuously, utilizes the upper button function pushed up and drive, upper button.
During torque wrench moment A >=50KN.m, first utilize top driving device is detained and functionally detain to 50KN.m, then utilize the upper button function of continuous circulation device, continue to increase the moment of torsion of (A-50) KN.m;
Shackle process: it is that the torque wrench moment of drilling rod is AKN.m that known precondition meets, and the maximum break-out torque of continuous circulation device is 40KN.m. When carrying out shackle, first utilizing the clamping back tongs of continuous circulation device to clamp drilling rod, in utilization, shackle oil cylinder carries out shackle, starts spinner motor spinner simultaneously, if screw thread can normally be unloaded out, then shackle completes; As shackle can not be carried out, then go up shackle oil cylinder to remain to starting position and be failure to actuate, but the buckle press that unloads of oil cylinder can be very high, when upper shackle oil cylinder keeps initial high pressure break-out torque, the shackle function starting top driving device carries out shackle, then acting on the moment of torsion unloading buckle joint is that the break-out torque 40KN.m that break-out torque B is superimposed with continuous circulation device is driven on top, i.e. (B+40) KN.m, and push up and drive between drilling rod or moment of torsion between thribble drilling rod and drilling rod is only BKN.m, much smaller than the moment of torsion suffered by shackle joint, other joints can not be caused to thread off. When spinner motor encoder detects motion, proving that button unloads out, superposition shackle function stop is driven on top, utilizes spinner motor spinner simultaneously, completes shackle function.
A kind of method improving break-out torque on continuous circulation device; It is applicable to continuous circulation device and pushes up the on-line operation system driven. Upper button process preferentially uses button on the torque wrench moment that drives of top, when push up drive torque wrench moment do not reach on-the-spot required torque wrench moment, the then torque wrench moment of the continuous circulation device of superposition.
During shackle, the preferential shackle function using continuous circulation device, cannot complete the prerequisite of shackle at continuous circulation device under, at the break-out torque that superposition top is driven. When spinner motor encoder detects that main shaft has an action, stop the shackle function that superposition top is driven, utilize the spinner motor of continuous circulation device to complete spinner.
As mentioned above, it is necessary, explained by embodiments of the invention, but as long as substantially not departing from the inventive point of the present invention and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art. Therefore, such variation is also all included within protection scope of the present invention.
