At first, cause the position deviation between bottom measurement pipe nipple and the top drilling tool easily, produce measure error.Though this coupling shock-absorbing connection relies on the elasticity of rubber to reach the damping purpose, but because the length of underground survey pipe nipple after linking together is longer, the bottom measures that pipe nipple will be subjected to the elastic deformation effect of gravity and rubber bodies itself and downward-sloping, departs from borehole axis; In addition, when down-hole equipment rotates, because the elastic reaction of rubber bodies, the bottom measure pipe nipple will and and produce a distortion deflection angle between the drilling tool of top, and this deflection angle can make the output signal of measuring deviation sensor in the pipe nipple can not truly reflect the attitude of drilling tool, and the deviation of these two kinds of deviation mechanical locations all can cause measure error.
Secondly, rubber bodies ruptures because of sharp pounding easily.Because this coupling shock-absorbing connection two ends are metal connector, the centre only relies on one section rubber bodies to carry out the damping connection, because instrument is operated under the situation of down-hole sharp pounding and impact, under vibrations and percussion repeatedly, make rubber fatigue easily, aging and rupture, in case rupture, the measurement pipe nipple of its underpart will be worked, and to avoid the generation of this situation, need regularly the tired index of rubber bodies to be detected, directly periodic replacement, the former has bigger difficulty on concrete enforcement, and the latter can cause the increase of instrument use cost inevitably.
Summary of the invention:
The objective of the invention is the shock-absorbing connection that is used for wireless drilling measurer in the petroleum drilling engineering in order to be provided at, compared with prior art, this shock-absorbing connection has overcome the shortcoming that existing shock-absorbing connection makes measuring apparatus generation measure error and rubber bodies rupture because of sharp pounding easily easily, not only can reach damping effect, and can be at the down-hole reliably working.
Shock-absorbing connection of the present invention, comprise Connection Block, the shock-absorbing connection body, rubber bodies, the socket mouth, be connected and fixed hole and hole for injecting glue, it is characterized in that the Connection Block top is processed into flange plate-like disk, have groove around the disk, the middle and upper part is processed with a disk, it between two disks circle footpath body, cylinder is processed in the bottom, leave boss on the cylinder, dug groove in the boss, the Connection Block center also is processed with through hole, and the shock-absorbing connection body is a cylindrical tube, be processed with boss in the cylindrical shell, dig the groove that matches with boss in the Connection Block cylinder in the boss, semicircular body is processed in the bottom, has the socket mouth on the semicircular body and is connected and fixed the hole, Connection Block inserts the shock-absorbing connection body, and injects rubber bodies and fix.A side of shock-absorbing connection body is drilled with a hole, and the upper surface is symmetrily processed with a groove, and the bottom semicircular body axially is processed with the hole of leading to cylindrical tube.
The beneficial effect that shock-absorbing connection of the present invention has is, this shock-absorbing connection injects rubber between Connection Block and shock-absorbing connection body, between Connection Block and the shock-absorbing connection body boss that cooperatively interacts is arranged, be used for improving the mechanical strength of rubber bodies, both relied on the elasticity of rubber bodies to reach the damping purpose, rubber bodies is ruptured because of deformation and produce and measure the variation of pipe nipple mechanical location, overcome the shortcoming that existing shock-absorbing connection makes measuring apparatus generation measure error and rubber bodies rupture because of sharp pounding easily easily, not only can reach damping effect, and can be at the down-hole reliably working.
