Abstract
A key separation prevention structure of a wireless inclinometer while drilling relates to the technical field of drilling tools and mainly comprises a wireless inclinometer while drilling, wherein a location hole is formed in an orientation sub at the lowermost end of the wireless inclinometer while drilling; and a jackscrew props against a guiding shoe part of the wireless inclinometer while drilling. By arranging the jackscrew to prop against the guiding shoe part of the wireless inclinometer while drilling, the key separation prevention structure can prevent the wireless inclinometer while drilling from being separated from a location key, and has the advantages of simple structure, convenience in operation, low cost and saved assembly time. Once an unusual condition occurs in the pit, the key separation prevention structure can be fished up by a fishing tool to reduce loss to the maximum degree.
Description
Technical field
The utility model relates to the drilling tool technical field, relates in particular to a kind of oil drilling wireless drilling inclinometers key-separation structure.
Background technology
In petroleum drilling engineering, it is more and more extensive that directed drilling is used, and wireless drilling inclinometers is the important tool of carrying out directed drilling, because of its stable performance, the high demand of this quasi-instrument that makes of reliability increasing.Wireless drilling inclinometers is comprised of ground installation and device for subsurface measuring, and ground installation comprises pressure sensor, exclusive data processing instrument, remote data processor, computer and stube cable etc.; Device for subsurface measuring mainly is comprised of pulser, inserting tube, battery sleeve, centralizer and fishing head.
The key-separation structure of wireless drilling inclinometers as shown in Figure 1 at present, formed by wireless drilling inclinometers 1, anticreep pole 2 and pallet 3, when assembling, the length of anticreep pole 2 must determine by the length of measuring non magnetic drill collar 5, and measurement size must guarantee that precision is high, if anticreep pole 2 is long, drill collar will damage instrument when connecting, otherwise, do not compress instrument, just can not play the effect of key-separation.This key-separation structure built-up time length, complicated operation, cost are high, in case that the down-hole occurs is abnormal, instrument can not be salvaged, and loses very large.
The utility model content
The purpose of this utility model is to provide a kind of wireless drilling inclinometers key-separation structure, to solve built-up time length that prior art exists, complicated operation, problem that cost is high.
The utility model mainly is comprised of wireless drilling inclinometers, and solving the technical scheme that its technical problem adopts is at wireless drilling inclinometers orientation joint bottom, a locating hole to be set, and withstands the guide shoe position of wireless drilling inclinometers by jackscrew.
The beneficial effect of the utility model device is to withstand the guide shoe position of wireless drilling inclinometers by jackscrew, make wireless drilling inclinometers can not break away from positioning key, simple in structure, easy to operate, cost is low, assembling the time saves time, in case unusual condition appears in the down-hole, can salvage with fishing tool, at utmost reduce the loss.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of prior art wireless drilling inclinometers key-separation structure;
Fig. 2 is the structural representation of the utility model wireless drilling inclinometers key-separation structure.
1 wireless drilling inclinometers in figure, 2 anticreep poles, 3 pallets, 4 orientation joints, 5 non magnetic drill collars, 6 locating holes, 7 jackscrews, 11 guide shoe positions.
The specific embodiment:
A kind of wireless drilling inclinometers key-separation structure mainly is comprised of wireless drilling inclinometers 1, bores a locating hole 6 in wireless drilling inclinometers 1 orientation joint 4 parts bottom, withstands the guide shoe position 11 of wireless drilling inclinometers 1 by jackscrew 7.
The utility model withstands the guide shoe position 11 of wireless drilling inclinometers 1 by jackscrew 7, make wireless drilling inclinometers 1 can not break away from positioning key, thereby reach the key-separation effect.
Claims (1)
1. a wireless drilling inclinometers key-separation structure, mainly be comprised of wireless drilling inclinometers, it is characterized in that at wireless drilling inclinometers orientation joint bottom, a locating hole being set, and withstands the guide shoe position of wireless drilling inclinometers by jackscrew.
