Abstract
The utility model relates to a direction gauge of screw drill used for the well drilling construction of horizontal wells and directional wells. The direction gauge of a screw drill is composed of a clip 1, a screw 2, a nut 3, a pin 4, a wire rope 5 and a weight dropper. The direction gauge of the screw drill has the advantages of compact structure and convenient operation. The direction gauge of the screw drill can accurately identify the bending direction of the screw drill to one end near a directional joint when the horizontal well works, and therefore, the construction is convenient, and the construction efficiency of the well drilling is improved. The direction gauge of the screw drill can be used repeatedly for many times.
Description
Technical field:
The utility model relates to a kind of device for subsurface measuring that is used for horizontal well, directional well drilling construction.
Background technology:
In recent years, horizontal well directional well technology has obtained and has developed rapidly and apply, and obtained to improve the economic benefit of oil well output more than 3 times, make heavy crude reservoir, fractured reservoir, end water advance the bigger particular oils gas reservoir of exploitation difficulty such as oil-gas reservoir and book oil reservoir, oil-gas Layer exploitation also to realize breakthrough progress.Yet, because horizontal well directional well technology still is in research, development at present and progressively improves the stage, the horizontal well drilling construction needs the instrument instrument of application still comprehensive inadequately at present, use, operation is all convenient inadequately, what have influence on this technology further applies raising with effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of and curved side's direction of helicoid hydraulic motor accurately can be identified in horizontal well directional well drilling work progress near orientation joint one end, thus the helicoid hydraulic motor direction gage of convenient construction operation.
The utility model is to realize like this.This kind direction gage is made up of clip, screw, nut, pin, weight and cotton rope, penetrate screw in the circular hole that symmetrical two clip intermediate connection points overlap, and fix with nut screwing clamping, insert pin respectively in two circular holes of upper end, about between two pins the cotton rope with suitable length be connected, a weight is hung at the cotton rope middle part.During use, this direction gage clip under shed is fastened on helicoid hydraulic motor bent sub position, circumferentially rotates clip, point to the centre position of screw up to the weight lower end, observe the scale value on the curved pairing clip of direction of screw rod, and note; Pull down direction gage, be fastened on the other end of helicoid hydraulic motor, adjust the clip circumferential position, in the middle of weight points to screw, do a mark in the measured value position of record, this place is the curved direction extension herein of helicoid hydraulic motor.Pull down instrument, in order to using next time.Generally, when horizontal well drilling is constructed, helicoid hydraulic motor is connected with orientation joint, have certain angular difference between the seat key direction that indicates on curved side's direction of helicoid hydraulic motor and the landing nipple, and curved side's direction of helicoid hydraulic motor is at the end away from orientation joint.After using this direction gage, can the side's of bending direction be identified at helicoid hydraulic motor smoothly, thereby can make things convenient for horizontal well construction, provide reliable reference data for adjusting tool-face near orientation joint one end.
The utility model compact conformation, easy to operate, utilize it can be when horizontal well construction curved side's direction of helicoid hydraulic motor accurately to be identified near orientation joint one end, thereby convenient construction improve wellbore construction efficient.This measuring apparatus can repeat repeatedly to use.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of clip 1, screw 2, nut 3, pin 4, cotton rope 5 and weight 6, its structure, assembled relation are as follows: penetrate screw 2 in the circular hole that symmetrical two clip 1 intermediate connection points overlap, and tighten fixing with nut 3, insert pin 4 respectively in two circular holes of clip 1 upper end, about between two pins 4 cotton rope 5 with suitable length be connected, a weight 6 is hung at cotton rope 5 middle parts.Wherein, clip is " X " shape, bilateral symmetry, the upper end is little, and the lower end is big, intermediate interdigitated point is provided with the screw 2 that penetrates of coincidence and uses connecting hole, respectively be provided with an insertion pin 4 about the upper end and use circular hole, lower clamp is marked with 0～145 scale value, in order to identify the direction shown in the curved side, an aperture is respectively arranged on two pins 4, be used to penetrate cotton rope 5 it is connected.Cotton rope was sagging slightly after cotton rope 5 length were inserted well with pin 4 is advisable.Weight 6 hangs length and is advisable with the different screw mid point that arrives two clips.
