Description
Technical field
The present invention relates to a kind of measurement while-drilling instrument, more particularly to a kind of measurement while-drilling instrument self-locking device and method.
Background technology
The country using measuring instruments such as QDT, YST-48X, YST-48R when being oriented well operations, in order to prevent under
During brill, by measuring instrument ejection keyway to occur to take off key accident due to being returned on drilling fluid in drilling tool, what is used at present is general
It is that one normally closed type check valve is installed in instrument lower end all over way, the effect of this check valve is the drilling fluid of annular space when preventing lower bore
It is moved upwards in into drilling tool, the risk that instrument takes off key occurs when avoiding lower brill.But prevent instrument from taking off key using check valve
Way, at least there is following disadvantage：
1. increasing production cost.Check valve（Arrow type valve）Service life is short, in east China a well also with not needed getting off
It repairs, usage amount is very big, this directly increases production cost.
2. needing to carry out cementing operations when lower brill.Production cost is increased indirectly.
3. increasing underground risk.Downhole assembly has connect a connector with regard to more one of underground risk more.
4. increasing the labor intensity of construction personnel.
It is commonly used in the Directional Well Measurement While Drilling construction of the instruments such as YST-48X, YST-48R, QDT at home at present,
Also this downhole tool of check valve therefore has been used in large quantities.For risk that is cost-effective, reducing generation down-hole accident, mitigate
The labor intensity of construction personnel, construction party are badly in need of a kind of safe and simple replacement device.

Including following procedure：
First, in outer barrel（2）Middle part be circumferentially with three slip grooves（12）, three slips（4）It is placed in slip groove respectively
（12）It is interior, slips（4）Outer surface be machined with grasping teeth（17）, in outer barrel（2）Middle part in survey be equipped with clinohedral（5）, clinohedral
（5）With three slips（4）Pass through T-slot（16）Connection, in outer barrel（2）One standard YST-48X standard of instruments of top tripping in
Fishing head（1）, fishing head（1）The spring conductor rod of lower part（14）On be set with locking spring（3）, fishing head（1）Lower part is logical
Cross screw thread and clinohedral（5）Top connection, locking spring（3）It is arranged in clinohedral（5）Top, locking spring（3）It is in
Outer barrel（2）With fishing head（1）Between form cavity（13）It is interior, outer barrel（2）With instrument joint housing（7）Between pass through ball bearing
（6）Connection, spring（8）It is sleeved on instrument joint housing（7）On, in little spring（8）Lower part be equipped with pleasure boat（9）, in pleasure boat
（9）Lower part be equipped with semicircle card valve（10）, in instrument joint housing（7）It is internally provided with ten core print seat components（11）, instrument connector is logical
Cross pleasure boat（9）It is connect with measuring instrument main body；
Secondly, the device is passed through into the pleasure boat on instrument connector on the runway of well site（9）It links together with measuring instrument main body,
With rope sling and electric hoist rig floor on measuring instrument main hanger, it is put into a space of rig floor vertically, makes the fishing head of the device
（1）More than drilling floor surface, the lateral pin on fishing rod is caught with specific purpose tool（15）, then electricity consumption cucurbit slings measuring instrument main body and puts
In the non magnetic drill collar for entering well head, the slips on self-locking mechanism（4）Contraction state is under the action of measuring instrument main body is conducted oneself with dignity,
The decentralization for not interfering with measuring instrument main body, after instrument successfully sits key, slips（4）It is no longer influenced by the dead weight of measuring instrument main body
Influence, locking spring（3）Push clinohedral（5）It moves downward, clinohedral（5）Drive three circumferentially uniformly distributed slips（4）To
Outer stretching pushes against on drilling tool inner wall, and due to the angle very little of clinohedral, angle is less than 30 degree, slips（4）Outwardly directed torque
There are amplification, slips（4）The grasping teeth on surface（17）Wedging drilling tool inner wall holds out against and forms locking, slips in drill collar inner wall（4）With
Drilling fluid upward impact force and measuring instrument main body when the circumferential locking force of drill collar inner wall is much larger than lower brill suffered by instrument
Dead weight.
