Description
Technical field
The invention belongs to the drilling engineering technical field of the resources such as petroleum gas, specifically, being a kind of rotary auxiliary
Help the specific purpose tool and application method that LWD tool combines.
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, general requirement is 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 because needing entirely to be pressed in well head with drill tools weight, rubs
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 using chain wrench promotion with drill tools
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 with carrying
Frictional resistance becomes larger and causes not relatively rotate between them between liter pipe nipple, and is produced between lifting sub and LWD tool
It is raw to relatively rotate, and then be buckled to cause to come off and injure operating personnel by a crashing object, it even results in drilling tool and falls in well, cause " fish " accident；
3) 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 that, together
When labor intensity it is excessive, and operation timeliness is extremely low.Therefore, a kind of rotary auxiliary LWD tool combination of necessary invention
Specific purpose tool, do not need in operation process entire LWD tool weight being pressed in well head, but by LWD tool
Most of weight continue to be suspended on top and drive on elevator, release only a few weight is pressed in well head and is used for drawing button, will not be because of silk
Pressure is excessive between button causes thread alternating that screw thread is caused to damage；The specific purpose tool of rotary auxiliary LWD tool combination can be very big
Spin friction resistance is reduced, operating personnel's quantity is reduced, when mitigation operating personnel pushes chain wrench drive LWD tool rotation
Operation intensity；Because easily rotating, first reversely rotate after LWD tool determines right-hand thread before button operation is drawn and rotate in the forward direction again
LWD tool carries out drawing button, avoids thread alternating risk；Because specific purpose tool can rotate, specific purpose tool can be also avoided with being surveyed with brill
It is relatively rotated between well tool, and then is buckled to come off and injures operating personnel by a crashing object and " fish " accident risk occurs, greatly reduce operation
Risk improves operating efficiency, reduces operating cost.
