Abstract
The invention relates to the technical field of coiled tubing drilling and completion, in particular to a coiled tubing drilling anti-torque device. The inner wall of the lower end of an upper joint of the device is hermetically connected with a torque sleeve in a threaded manner, a connecting sleeve is disposed at the lower end of the upper joint and sleeves the outer side of the torque sleeve, a step on the inner wall of the connecting sleeve is hung at the position of an outer step at the lower end of the torque sleeve, the torque sleeve locks the connecting sleeve through a self-locking block, a disc spring is disposed on the inner side of the self-locking block, a limiting sleeve is hermetically connected onto the inner side of the torque sleeve in the threaded manner and retains the disc spring, and the lower end of the connecting sleeve is hermetically connected with a lower joint in the threaded manner. The coiled tubing drilling anti-torque device has the advantages that the problems that a coiled tubing is damaged and a screw drill is faulted due to excessive large torque and screwdrill drill reactive torque accumulation caused by stratum obstruction in the coiled tubing drilling process are avoided, high-pressure and high-speed drilling can be realized during coiled tubing drilling, the coiled tubing drilling period is further shortened and the drilling cost is reduced.
Description
Technical field:
The present invention relates to a kind of pipe bit completion technique field, the particularly anti-torquer of a kind of continuous-tube drilling well continuously.
Background technology:
In the continuous-tube drillng operation of present stage, due to the not revolvable particularity of continuous-tube, the pressure of the drill, moment of torsion and DHA are restricted, when stratum hinder moment of torsion be greater than helicoid hydraulic motor be supplied to drill bit creep into moment of torsion time, rotor torque is easily caused to accumulate, and react on stator and down-hole equipment, reaction torque release in time can not can cause the problems such as continuous-tube damage, helicoid hydraulic motor fault and load transfer difficulty, so can only low the pressure of the drill, high drilling speed creep into, seriously constrain efficiency and the application of continuous-tube drilling well.
Summary of the invention:
The technical problem to be solved in the present invention is to provide the anti-torquer of a kind of continuous-tube drilling well, the arrangement achieves and avoid in continuous-tube drilling process because the continuous-tube damage that stratum obstruction moment of torsion is excessive and helicoid hydraulic motor awl reaction torque is accumulated and caused, helicoid hydraulic motor failure problems, when can realize continuous-tube drilling well, large the pressure of the drill, high drilling speed creep into, further shorten continuous-tube drilling period, reduce drilling cost.Overcome that the continuous-tube caused because stratum hinders the accumulation of moment of torsion excessive and helicoid hydraulic motor awl reaction torque in existing continuous-tube drilling process damages, helicoid hydraulic motor failure problems, can only low the pressure of the drill, the high drilling speed deficiency of creeping into.
The technical solution used in the present invention is: the anti-torquer of a kind of continuous-tube drilling well, comprises top connection, adapter sleeve and lower contact; Top connection lower end inner wall thread seal connects torque sleeve, adapter sleeve is placed in top connection lower end and is sleeved on outside torque sleeve, adapter sleeve inwall step is articulated in outer step place, torque sleeve lower end, torque sleeve locks adapter sleeve by self-locking block, butterfly spring is placed in inside self-locking block, stop collar thread seal to be connected to inside torque sleeve and to block butterfly spring, and adapter sleeve lower end thread seal connects lower contact.
The invention has the beneficial effects as follows: present invention, avoiding in continuous-tube drilling process because the continuous-tube damage that stratum obstruction moment of torsion is excessive and helicoid hydraulic motor awl reaction torque is accumulated and caused, helicoid hydraulic motor failure problems, when can realize continuous-tube drilling well, large the pressure of the drill, high drilling speed creep into, further shorten continuous-tube drilling period, reduce drilling cost.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, the anti-torquer of a kind of continuous-tube drilling well, comprises top connection 1, adapter sleeve 4 and lower contact 6; Top connection 1 lower end inner wall thread seal connects torque sleeve 2, adapter sleeve 4 is placed in top connection 1 lower end and is sleeved on outside torque sleeve 2, adapter sleeve 4 inwall step is articulated in outer step place, torque sleeve 2 lower end, torque sleeve 2 locks adapter sleeve 4 by self-locking block 3, butterfly spring 7 is placed in inside self-locking block 3, stop collar 5 thread seal to be connected to inside torque sleeve 2 and to block butterfly spring 7, and adapter sleeve 4 lower end thread seal connects lower contact 6.
In continuous-tube drilling process, connect continuous-tube and top connection of the present invention 1 with connector, lower contact 6 connecting screw rod drilling tool.In drilling process; when the obstruction moment of torsion that drilling strata provides be greater than normally creep into nominal torque that continuous-tube can bear time; adapter sleeve 4 skids off self-locking block 3 and rotation of sliding; adapter sleeve 4 is connected because there is no with top connection 1; so the continuous-tube on top connection 1 and top thereof does not rotate; now this unit protection continuous-tube is not by this part torsional interaction, reduces continuous-tube damage, extends the continuous-tube life-span.In addition; in the course of the work; the rotor also accumulation moment of torsion of helicoid hydraulic motor; when creeping into stopping, reaction torque can discharge and act on screw drilling tool stator and continuous-tube, by this device; helicoid hydraulic motor and continuous-tube can be protected equally not to destroy by this part moment of torsion; and large the pressure of the drill, the drilling well of high drilling speed continuous-tube can be carried out, shorten continuous-tube drilling period, reduce continuous-tube drilling cost.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
