Property connector one end be connected with retainer ring, the arcuate surface of the other end and arc spacer connects, on each Flexible Connector
A pressure sensor is provided with, the pressure sensor is connected with Drilling Control system, wherein：
Pressure sensor：Pressure detecting information is sent to Drilling Control system；
Drilling Control system：The pressure detecting information of pressure sensor transmission is received, when pressure detecting information exceeds pressure
During threshold value, alarm of sounding.Further, to overcome prior art problem, the present invention devises a kind of detection and localization warning device,
Drilling rod is arranged in the annulus that multiple arcs spacer is formed, when drilling rod shifts, one of arc can be touched
Shape spacer simultaneously applies a pressure to arc spacer, and the Flexible Connector being now connected with the arc spacer can be pressed
Contracting, the pressure sensor on the Flexible Connector sense the decrement of Flexible Connector, gather pressure information and are transferred to
Controller in Drilling Control system, a pressure threshold is preset with Drilling Control system, when pressure information is beyond pressure
During force threshold, Drilling Control system will sound alarm, can remind staff by way of alarm song or presentation of information
Pay attention to.The piston in hydraulic system is caused to be offset with barrel generation by drilling rod skew by being solved with upper type, and the people that works
The problem of member can not have found to check in time；Which greatly reduces the inspection workload of staff, can have and be directed to
Property detect, and has higher practical value.
Preferably, the Flexible Connector is spring, and the center line of the spring passes through the center of circle of arc spacer.Enter one
Step, the coefficient of elasticity of spring is higher, and elastic resume speed is fast, and cost is relatively low, easy to manufacture, it is advantageous to using spring as
Flexible Connector.
Preferably, the inner concave of the arc spacer is provided with sheet rubber.Further, when drilling rod shifts,
Sheet rubber can be protected to drilling rod and arc spacer, avoid mutually wearing between the two.
Several mounting rods are additionally provided with retainer ring bottom face, the mounting rod is distributed in a ring on the outside of retainer ring,
And the center line of mounting rod and the centerline parallel of retainer ring.Further, multiple mounting rod insertion ground, can make fixed environmental protection
It is fixed to keep steady.
The outer surface of the mounting rod is provided with corrosion-inhibiting coating.Further, corrode in many of oil exploration environment
Property material, mounting rod outer surface spray one layer of corrosion-inhibiting coating, effectively most of corrosive substance can be completely cut off,
Mounting rod is protected with this, extends its service life.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is applied to the positioner of oil exploration drilling, including a retainer ring, several arc spacers, institute
The center of circle for stating arc spacer overlaps with the center of circle of retainer ring, in addition to the Flexible Connector with the quantity such as arc spacer,
A pressure sensor is provided with each Flexible Connector, the pressure sensor is connected with Drilling Control system, pressure
Force snesor gathers pressure information and the controller being transferred in Drilling Control system, when pressure information is beyond pressure threshold
When, Drilling Control system sounds alarm to remind staff to pay attention to, solved with this is caused in hydraulic system by drilling rod skew
Piston and barrel produce skew, and the problem of staff can not have found to check in time；The present invention greatly reduces work
Make the inspection workload of personnel, can have and targetedly be detected, there is higher practical value.
