Abstract
The utility model relates to a laser calibration device for measuring an angle difference of a directional well project. The device consists of a wideninged clamphoop, a support rod and a plurality of light sources, wherein the wideninged clamhoop consists of an elastic arc-shaped substrate, a plurality of elastic gaskets, a plurality of rigid gaskets and a plurality of fastening bolts, the rigid gaskets and the elastic gaskets are fixedly arranged on the inner surface of the elastic arc-shaped substrate in sequence, and a gap is arranged between every two gaskets; and the support rod is fixedly connected with the widening clamhoop, and is connected with two light source installation cylinders which are connected in series are arranged on the support rod, the inner sides of the light source installation cylinders are provided with elastic gaskets in an attachment manner, and aone light source is arranged in every installation cylinder. By adopting the device, the position of a measurement point can be calibrated through the two laser sources, and accurate calibration of a top keyway can be realized. The device can still work normally in bad weather and poor light, and the reliability of measurement can be improved. In addition, since the clamhoop can be adjusted, the tool is suitable for pipes of various sizes and has high applicability.
Description
Technical field
The utility model relates to a kind of measurement calibration tool of the raising engineering angular difference precision for directional well, horizontal well construction process.
Background technology
The certainty of measurement of angular difference directly affects the precision of directed construction even directly affects workmanship in the directional well work progress, and wherein the engineering angular difference measure that precision is not high to have perplexed directed engineers for many years especially, main cause be when measuring pulser keyway and power drilling tool keyway at a distance of too far (when using common MWD about 16 meters, use LWD especially above 20 meters), particularly evening is owing to the reason Measurement accuracies such as light weather are more difficult.The at present angular difference of directional well measurement is modal to be to hang by the MWD on the top to make marks, then mark in the power drilling tool flash tag plane of lower end by naked-eye observation, measure the calculating angular difference by circumference, the advantage of this method is that cost is low, measure simple and fast, but shortcoming is too to rely on naked-eye observation, is subjected to the impact of weather and light very large.
Domestic in recent years the angular difference measuring tool that spot light cooperates the dial disc of bottom also appearred depending on, such as patent 201120005108.1 disclosed contents, its advantage is directly perceived, it is less affected by light, requirement is very strict but shortcoming is measurement, as requires drilling tool static, and the relativeness of light source and dial is more stable, and do not consider the off-centre of drilling tool, and this almost is impossible for tens meters drilling tool.
Summary of the invention
The purpose of this utility model provides a kind of laser calibration device that can improve engineering angular difference certainty of measurement in directional well and horizontal well construction process.
Embodiment of the present utility model is as follows: this measurement directional well engineering angular difference with the laser calibration device by widening clip, support bar and light source form, the described clip of widening is comprised of flexible arc substrate, elastomeric pad, rigid gasket and fastening bolt, rigid gasket and elastomeric pad are arranged in order and are fixed on flexible arc substrate inner face, leaving certain gaps uncovered by the economic plan in the middle of per two pads; Support bar is fixedly connected on to be widened on the clip, and the light source of two included elastomeric pads of series connection is laid cylinder on the support bar, and each is laid and is placed with a light source in the cylinder.
The described elastomeric pad of widening on the clip is 2, and is fixed on fastening bolt one end; Described rigid gasket is 1.
The utility model takes full advantage of the advantage of laser straightline propagation, by the orientation of two lasing light emitter calibration measurements points, has greatly remedied the deficiency of existing scaling method, has realized the Accurate Calibration of top keyway; Again according to the characteristic of laser stabilization, it still can be worked when relatively poor than atrocious weather and light, improved the reliability of measuring; Comprehensive above-mentioned advantage further improves the accuracy of measurement, breaks away from the absolute dependence to naked-eye observation, improves the efficient of directed drilling.Utilize in addition its controllability of clip, thereby make the pipe that this cover instrument can suitable for multiple sizes, improve the instrument applicability.

The specific embodiment
Be described further below in conjunction with 1 pair of the utility model of the accompanying drawing in the manual.
By widening clip, support bar 5 and two lasing light emitters form this measurement directional well engineering angular difference with the laser calibration device.The described clip of widening is comprised of flexible arc substrate 1, two elastomeric pads 2, a rigid gasket 3 and two fastening bolts 4, and wherein three pads and flexible arc substrate 1 are fixed together, and enough wide breach is stopped in the centre; Two long light sources of series connection are laid a 6(length less than lasing light emitter on the described support bar 5), light source is laid cylinder 6 included elastomeric pads, and diameter is less than lasing light emitter; Rigid gasket 3 and therein heart punching (diameter and support bar diameter are consistent) after the flexible arc substrate fixes during making, then with support bar and clamp connection, relative variation does not occur in the two in the welding assurance measuring process after position and the direction thereby adjust.In practical operation, fastening bolt 4 is dismantled, with hoop sleeve outside the MWD hanging pup joint, then the stuck point card outside round bar 5 one ends and the MWD hanging pup joint is accurate on the support bar, tighten fastening bolt 4, guarantee that clip and MWD hanging pup joint are adjacent to, because employing is widened clip and is guaranteed that like this clip central axis is consistent with MWD hanging pup joint axis, thereby guarantee two light sources lay the cylinder 6 with the MWD hanging pup joint at grade, and two lasing light emitters straight down, lasing light emitter is placed in light source lays in the cylinder 6, because the elastomeric pad inner ring diameter is slightly less than lasing light emitter, thereby lasing light emitter is well fixed and centering.After finishing drilling tool mentioned to power drilling tool keyway position and exceed drilling floor surface, the line with two laser spots extends to disk edge like this, and the power drilling tool keyway is also demarcated at disk edge simultaneously, measures 2 distances, calculates angular difference, and measurement accuracy is high.
The utility model includes but not limited to above embodiment, as uses other straightline propagations instead and the strong light source of light-gathering also drops in the utility model scope.
