Abstract
The invention relates to the technical field of directional well wired skew cables in petroleum drilling, and discloses a directional well wired skew cable fixing anti-collision device which comprises a body and a connection end, wherein the upper end of the connection end is fixed with the lower end of the body; a groove, the axial line of which is along the vertical direction, is arranged on the outer side of the body; an internal thread mounting groove is arranged at the upper part of the body; through holes which are communicated with the internal thread mounting groove are arranged in the body and the connection end; and an external thread is arranged on the outer side of the connection end. The well wired skew cable fixing anti-collision device is reasonable and compact in structure, convenient for use and capable of preventing easy cable breakage in the directional operation of a wired skew instrument through the cooperation of the connection end and the body, and has the characteristics of being easy for manufacturing and simple in operation, so that the production cost is reduced and the work efficiency is improved.
Description
Technical field
The present invention relates to the wired skew back cable technology of oil drilling directional well field, is fixedly anticollision device of the wired skew back cable of a kind of directional well.
Background technique
In the construction of oil drilling directional well; often can use wired skew back instrument to carry out positioning operation; while making up a joint, wired instrument need to be proposed at every turn; auxiliary time is longer; in construction, need at the scene more durable cable to derive instrument, after cable is derived drilling tool, in the position of drill pipe coupling; due to the collision of drill pipe coupling and internal surface of sleeve pipe, can touch power-off cable.
Summary of the invention
The invention provides fixedly anticollision device of the wired skew back cable of a kind of directional well, overcome the deficiency of above-mentioned prior art, it can effectively solve cable when wired skew back instrument carries out positioning operation and easily touch disconnected problem.
Technological scheme of the present invention realizes by following measures: the wired skew back cable of a kind of directional well is anticollision device fixedly, comprise body and connecting end, the upper end of connecting end and the lower end of body are fixed together, in the outside of body, there is axis groove vertically, on the top of body, there is internal thread mounting groove, in the inside of body and connecting end, there is the through hole being connected with internal thread mounting groove, in the outside of connecting end, have outside thread.
The further optimization and/or improvements to foregoing invention technological scheme below:
Can there be the up big and down small guiding conical surface lower end of above-mentioned internal thread mounting groove, in the upper inside wall of internal thread mounting groove, can have internal thread.
The quantity of above-mentioned groove can be five and be evenly distributed on the outer side surface of body.
Above-mentioned groove is wide can be 10 millimeters, and groove is high can be 10 millimeters.
Reasonable and compact in structure of the present invention, easy to use, by being used in conjunction with of connecting end and body, prevented that cable easily touches disconnected when wired skew back instrument carries out positioning operation, have and be easy to manufacture and feature simple to operate, reduced cost of production, improved working efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is looked half section structural representation for the master of most preferred embodiment of the present invention.
Accompanying drawing 2 is the plan view of accompanying drawing 1.
Coding in accompanying drawing is respectively: 1 is body, and 2 is connecting end, and 3 is groove, and 4 is internal thread mounting groove, and 5 is through hole.
Embodiment
The present invention is not subject to following embodiment's restriction, can determine concrete mode of execution according to technological scheme of the present invention and actual conditions.
In the present invention, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing, the invention will be further described:
As shown in accompanying drawing 1,2, the wired skew back cable of this directional well fixedly anticollision device comprises body 1 and connecting end 2, the lower end of the upper end of connecting end 2 and body 1 is fixed together, in the outside of body 1, there is axis groove 3 vertically, on the top of body 1, there is internal thread mounting groove 4, in the inside of body 1 and connecting end 2, there is the through hole 5 being connected with internal thread mounting groove 4, in the outside of connecting end 2, have outside thread.During use, connecting end 2 and drilling rod are fixedly installed togather by drill pipe coupling, cable is derived after drilling tool water hole, up and be arranged in the outside groove 3 of body 1 along drilling rod and drill pipe coupling outer wall.The external diameter of body 1 is greater than the external diameter of drill pipe coupling, prevents from touching power-off cable in the collision of drill pipe coupling place cable and internal surface of sleeve pipe.
Can be according to actual needs, to the wired skew back cable of above-mentioned directional well fixedly anticollision device make further optimization and/or improvements:
As shown in Figure 1, there is the up big and down small guiding conical surface lower end of internal thread mounting groove 4, in the upper inside wall of internal thread mounting groove 4, has internal thread.Like this, in the upper inside wall of internal thread mounting groove 4, there is internal thread to be convenient to be installed together with drilling rod.
As shown in Figure 2, the quantity of groove 3 is five and is evenly distributed on the outer side surface of body 1.Like this, be convenient to cable and be arranged in groove 3, prevent that body 1 from colliding cable with internal surface of sleeve pipe collision.
As required, groove is wide is 10 millimeters, and groove is high is 10 millimeters.
Above technical characteristics has formed most preferred embodiment of the present invention, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs non-essential technical characteristics, meets the demand of different situations.
