Background technology
At present, along with the increasing of global oil exploitation dynamics, directional well and horizontal well production technical development are very fast.Directional well and horizontal well drilling measuring technique develop and have obtained effective achievement to highly difficult direction.Measuring apparatus is developed into limited to brill by the artificial single-point orientation that falls behind, all realized the measurement of MWD(wireless drilling now basically) and expanded LWD instrument series.But use MWD instrument construction hour angle difference and measure the difference very big with the wired drilling existence, the wired drilling orientation joint is directly to link to each other with power drilling tool, and the sign of MWD measures self tool-face is on the MWD pipe nipple, being marked on the power drilling tool bent sub of power drilling tool tool-face, between MWD pipe nipple and power drilling tool, also be connected with non magnetic drill collar (or not having magnetic pressure-bearing drilling rod) and other according to the actual conditions needs use as back pressure valve, LWD instrument etc., total length between the mark of the sign of self tool-face of measuring of MWD and power drilling tool tool-face just has 13-22 rice like this, has brought very big trouble for the measurement of angular difference.On-the-spot directional well engineer is stained with a tangible mark with adhesive tape on the sign of self tool-face that MWD measures, promote tubing string then the mark of power drilling tool tool-face is exposed well head, mode with range estimation aligns visible marking and the power drilling tool that is stained with adhesive tape on the MWD pipe nipple up and down, use one again the length in week between the tape measure upper-lower position, relation by central angle and girth calculates corresponding differential seat angle, as the foundation of adjusting the tool face azimuth, the result of Ce Lianging is that error is bigger like this, it is slow to test the speed, inconvenient site operation.
Summary of the invention
The utility model provides a kind of horizontal well, directional well wireless drilling angular difference measuring instrument in order to solve the prior art above shortcomings; Simple in structure, easy to operate, utilize measuring instrument of the present utility model, when carrying out the construction of wellbore trajectory measurement while drilling, overcome the deficiency during the wireless drilling angular difference is measured, can directly measure the angular difference between self tool-face of power drilling tool tool-face and MWD at the scene in the construction exactly, measurement result degree of accuracy height.
The technical scheme that the utility model technical solution problem adopts is:
A kind of horizontal well, directional well wireless drilling angular difference measuring instrument, comprise snap ring, following snap ring, label chi, the described snap ring of going up is provided with label chi inserted sheet socket, the label chi is provided with label blade, handle, the upper end of label blade is provided with label chi inserted sheet, the inserted sheet socket cooperates with inserted sheet, described upward snap ring, following snap ring comprise two semicircular ring respectively, be respectively equipped with screwed hole on two semicircular ring, two semicircular ring connect by screwed hole and bolt, are respectively equipped with 0～180 ° uniform graduation mark on two semicircular ring of described snap ring down.Represent 1 ° between two adjacent graduation marks, according to the needs of certainty of measurement, can between two graduation marks, increase graduation mark again.
The sign of inserted sheet socket and MWD on the last snap ring self tool-face vertically aligns, and 0 graduation mark of the angle scale on the following snap ring vertically aligns with power drilling tool tool-face mark.
At the scene in the work progress, at well head with power drilling tool, non magnetic drill collar (or not having magnetic pressure-bearing drilling rod) and other according to the actual conditions needs use do not have magnetic short section and connect as back pressure valve and LWD instrument etc. and MWD after, the last snap ring of this measuring instrument is fastened on MWD not to be had on the magnetic short section and uses bolton, the sign of noting going up self tool-face of label chi socket and MWD measurement on the snap ring in the fastening process vertically aligns, inserted sheet on the label chi is inserted the label chi socket of going up on the snap ring, shake the handle slow release label chi on the label chi box, the tool-face mark of upper lifting pipe post on power drilling tool exposes well head simultaneously, stop the upper lifting pipe post, to descend snap ring to be fastened on the power drilling tool and use bolton, and should will descend the zero graduation of the angle scale on the snap ring vertically to align with tool-face mark on the power drilling tool in the fastening process.At last that the label chi is vertically stretching and the graduation mark of the angle scale on the vertical graticule on the label chi and the following snap ring vertically alignd, just can directly read angle difference at this moment, note, as the reference frame of adjustment tool-face.The handle that shakes on the label chi box is regained the label chi, unload successively on the snap ring up and down bolt and up and down snap ring treat use next time.
The utility model beneficial effect:
1. simple in structure, easy to operate, self tool-face that can read directly that MWD measures by measuring instrument of the present utility model and the angular difference between the power drilling tool tool-face, the result that reads is accurate in institute;
2. easy accessibility, measuring instrument can repeat repeatedly to use.
