Description
Technical field
The utility model belongs to the drilling engineering technical field of the resources such as petroleum gas, specifically, being a kind of rotation
Formula assists the specific purpose tool of LWD tool combination.
Background technology
Before drillng operation, G.I.H carries out drillng operation after bottom drill tool is combined by rig floor using top drive.Bottom
There are some expensive, instrument precisions, spare less tool, such as LWD tool, geology delineation tool in portion's drilling tool
Deng, it need to be especially careful when combining operation, it is general to require to be combined operation without using iron driller, hydraulic tongs, turnbuckle clamp etc..
Scene generally clasps LWD tool ontology with chain wrench at present, and operating personnel pushes chain wrench that LWD tool is driven to be rotated into
Row draws button, upper button operation, has following drawback：1) easily thread alternating rubs because needing entirely to be pressed in well head with drill tools weight
Resistance is very big, and the excessive easily thread alternating of pressure causes screw thread to damage between screw thread contact surface when being rotated with drill tools using chain wrench promotion
It even damages, needs replacing new tool, timeliness is low；LWD tool is expensive simultaneously, and general cutfit is less, very
To no cutfit, operation will be forced to stop；2) top is driven elevator and is buckled on lifting sub, lifting sub and LWD tool
It connects, not damage screw thread in operation process, moiety by weight is still suspended on top and drives on elevator, leads to top drive elevator in this way and carries
Rise frictional resistance between pipe nipple become larger lead to them between do not relatively rotate, and produced between lifting sub and LWD tool
It is raw to relatively rotate, and then be buckled to cause to fall off and injure operating personnel by a crashing object, it even results in drilling tool and falls in well, cause " fish " accident；
3) it is to prevent from being buckled to, entire LWD tool weight is generally pressed in well head, operating personnel pushes well logging by chain wrench
Tool is difficult, and typically 5~6 people push chain wrench together, and personnel's erect-position is bad, easily falls down, and job safety is difficult to ensure, together

Most of weight of tool continues to be suspended on top drive elevator, and release only a few weight is pressed in well head and is used for drawing button, will not
Cause thread alternating that screw thread is caused to damage because pressure is excessive between screw thread；The specific purpose tool of rotary auxiliary LWD tool combination can
Spin friction resistance is greatly reduced, operating personnel's quantity is reduced, mitigates operating personnel and chain wrench is pushed to drive LWD tool rotation
Operation intensity when turning；It is positive again after first reversely rotating LWD tool before drawing button operation and determining right-hand thread because easily rotating
Rotation LWD tool carries out drawing button, avoids thread alternating risk；Because specific purpose tool can rotate, also can avoid specific purpose tool with
It is relatively rotated between brill logging tool, and then is buckled to fall off and injures operating personnel by a crashing object and " fish " accident risk occurs, greatly reduced
Operating risk improves operating efficiency, reduces operating cost.
