Description
Technical field
This utility model relates to outstanding dragging for device, is specifically related to that inclinometer well head is outstanding drags for device.
Background technology
Well drilling operation site commonly use self-floating single-point, throw-in type multiple spot and with bore deviational survey these three deviational survey mode,
Fishing head is all arranged at the inclinometer top that these three deviational survey mode uses, and is typically necessary and is hanged by suspension arrangement when deviational survey operation
The fishing head tangling inclinometer makes inclinometer enter in drilling tool, and suspension arrangement departs from the fishing head of inclinometer, and inclinometer is to drilling tool
In precalculated position, use suspension arrangement to take out from drilling tool, hang to well head and tear open after inclinometer end-of-job when well head
Except inclinometer.The size of the inclinometer that these three deviational survey mode uses is different at present, and its device hanging inclinometer is the most different, logical
With property is strong, function is the most single, it is impossible to when solution drilling fluid density is low, self-floating single-shot inclinometer can not emersion well simultaneously
Drag for device descending difficulty in drilling tool owing to buoyancy is the most outstanding in the case of mouth, drilling fluid density are higher and can not normally take out multiple spot survey
Safety and well head when tiltedly instrument, inclinometer move up and down from ground to drilling platforms operate the difficult problems such as labor intensity is big.
Utility model content
Technical problem to be solved in the utility model is that providing inclinometer well head to hang drags for device.
In order to solve the problems referred to above, according to the technical solution of the utility model, inclinometer well head is outstanding drags for device, including salvaging
Device, steel wire rope and suspension arrangement, the top of fishing device is provided with joint, and joint is provided with the first connection screw thread, and it is special
Point is: salvages card for two and is symmetricly set on inside fishing device by pin respectively, pin is equiped with jump ring；Salvage card bottom
For interior arcuation, the fishing head being beneficial to inclinometer enters salvaging card；When inclinometer fishing head along salvage card inner arc towards
During upper top, salvage card and rotate around pin, and make salvaging card automatically reset by the counteracting force of jump ring to block fishing head；Hang
The bottom of device is provided with the second connection screw thread, and fishing device is connected with suspension arrangement by screw thread；The top of suspension arrangement sets
It is equipped with sling；One end of steel wire rope is provided with hanging ring, and the other end is fixed on sling.
The preferred version dragging for device is hanged, at fishing device and suspension arrangement according to inclinometer well head described in the utility model
Between be provided with weighted lever, fishing device is threaded connection with weighted lever, and weighted lever is threaded connection with suspension arrangement.This
When preferred version mainly solves to take out multiple-shot survey instrument, mud density height buoyancy is outstanding greatly drags for the problem that device can not be descending.
Inclinometer well head described in the utility model hangs and drags for device and provide the benefit that: this utility model solves drilling fluid
The when that density being high or low inclinometer take out difficulty problem, applied widely, improve the upper and lower drilling platforms of inclinometer and
Safety time mobile, alleviates the labor intensity of operator, has the drilling fluid that safety is high, salvages size extensively, adapt to
The feature that density range is big, workable, this device is applicable to multiple shot tool, directional tool and self-floating single-shot survey
Instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of fishing device described in the utility model.
Fig. 2 is the structural representation of suspension arrangement described in the utility model.
Fig. 3 is the structural representation of weighted lever described in the utility model.
Detailed description of the invention
Seeing Fig. 1 to Fig. 3, inclinometer well head is outstanding drags for device, including fishing device 1, steel wire rope and suspension arrangement 7, salvages
The top of device 1 is provided with joint, joint is provided with the first connection screw thread 5a, salvages card 2 respectively by pin 3 symmetry for two
It is arranged on fishing device 1 internal, pin 3 is equiped with jump ring 4；Salvaging card 2 bottoms is interior arcuation, and the bottom of suspension arrangement 7 sets
Being equipped with the second connection screw thread 5b, fishing device 1 is connected with suspension arrangement 7 by screw thread；The top of suspension arrangement 7 is provided with sling
10；One end of steel wire rope 8 is provided with hanging ring 9, and the other end is fixed on sling 10.Steel wire rope 8 adjustable length.Outside lifting
Inclinometer is implemented movement, suspension, fishing by connecting hanging ring 9 by device.
In a particular embodiment, be connected between fishing device 1 with suspension arrangement 7 and have weighted lever 6, fishing device 1 with add
Weight bar 6 is threaded connection, and weighted lever 6 is threaded connection with suspension arrangement 7.
Operation principle of the present utility model is, when the fishing head of inclinometer upwards pushes up along the intrados salvaging card 2, makes
Salvage card 2 to rotate around pin 3, and make salvaging card 2 automatically reset by the counteracting force of jump ring 4 to block fishing head；Salvage dress
Put by catching the fishing head of inclinometer to be locked by inclinometer, can be able to salvage by designing different salvaging cards with manual unlocking
The fishing head of different size inclinometer, and can automatically reset, solve the problem that versatility is the strongest；Suspension arrangement and salvaging
Being threaded between device, can access the weighted lever of corresponding screw thread, steel wire rope connects suspension arrangement and lifting device, with
Time also solve drilling fluid density low time self-floating single-shot inclinometer often below well head 10～30 meters can not float up to bore
Cause instrument to take out difficulty at table top and be forced to trip out whole drilling tool in the problem taking out inclinometer.This device is owing to there being locking dress
Putting, and use steel wire rope and suspension arrangement to connect, intensity is higher, substantially increases inclinometer and moves peace from ground to drilling platforms
Quan Xing, it is no longer necessary to manpower lifts the upper and lower drilling platforms of inclinometer, reduces labor intensity.
