Abstract
A top drive well drilling device for a petroleum drilling machine comprises a box body, an inner sleeve, a main shaft, a hanging body, a connecting flange, a double-clip type back-up wrench and a sleeve body. The box body and the inner sleeve are in an interference fit. The hanging body is connected with the connecting flange. The connecting flange is connected with the inner sleeve to form a loading channel. A hanging ring is connected with the hanging body. The double-clip type back-up wrench is connected with the inner sleeve. A main bearing seat is fixedly arranged in the box body. The main shaft is connected with the box body through the main bearing seat to form another loading channel. According to the top drive well drilling device for the petroleum drilling machine, a double-channel mode is adopted and top drive stress is divided during the well drilling and drill pulling. The back-up wrench is prevented from rotating with the hanging body. Bottleneck problems of easy seal invalidation of the hanging body and easy oil leakage of a rotating head are solved. Compared with the prior art, bottleneck problems of fatigue wear of a main bearing part and easy oil leakage of the rotating head are solved. Time for top drive maintenance is saved. Manufacturing cost of well drilling is saved and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil-well rig top-drive drilling, relates more specifically to two load channel designs that a kind of oil-well rig carries with top-drive drilling load binary channels.
Background technology
At present, oil-well rig has two kinds with the top-drive drilling load structure, and a kind of structure is main shaft single channel carrying, and in drilling well and the operation such as make a trip, all load all act on the main shaft, and are delivered on the casing by base bearing.Because all load of this structure all act on the main shaft, therefore very easily accelerate the fatigue wear of main shaft and base bearing, greatly reduce the application life that drive on the top, shortened greatly the top and driven the time between overhaul cycle, increased cost of production.
Another structure is the fixed two load channel designs of wafer type back-up tong one side, and this structure is to put in by a single armed beam whole substructure being fixed on, and when on the wafer type back-up tong during shackle, inner sleeve can be subject to a lateral force.This structure reduces the application life of top-drive drilling so that the wearing and tearing of substructure and inner sleeve are accelerated, and increases cost of production.
The utility model content
The purpose of this utility model provides a kind of reasonable stress, reduces the wearing and tearing of main shaft and inner sleeve and fatigue damage, greatly improves top-drive drilling novel two load passages in application life.
For achieving the above object, the oil-well rig top-drive drilling that the utility model provides is comprised of casing, inner sleeve, main shaft, suspension body, adpting flange, wafer type back-up tong and sleeve body; Wherein:
Interference fit one inner sleeve in one casing, this casing;
One suspension body is connected with adpting flange, and adpting flange and inner sleeve are connected to form a load path;
One suspension ring are connected with suspension body;
The wafer type back-up tong is connected with the inner sleeve through sleeve body;
Be fixed with main bearing seat in the described casing;
One main shaft consists of another load path by main bearing seat and casing.
Described oil-well rig top-drive drilling, wherein, suspension body can carry out 360 degree rotations in inner sleeve, is provided with two oil ducts and six rotatory sealings between suspension body and the inner sleeve.
Described oil-well rig top-drive drilling, wherein, the wafer type back-up tong is circular profile.
Described oil-well rig top-drive drilling, wherein, an end of suspension ring is connected with elevator.
The beneficial effects of the utility model are:
Casing adopts the inner sleeve plug in construction, sets up two load passages; With stressed shunting, wafer type back-up tong employing sleeve body fixedly wafer type structure is fixed on by adpting flange and is fixed under the inner sleeve, and the wafer type back-up tong is not rotated with swiveling head in normal drilling well and the process that makes a trip.The wafer type back-up tong is to folder when upper shackle, and the stressed centering of wafer type back-up tong is good, and puts in power acted on equably, has avoided the lateral force problem of rotary sealing.Compare with known technology, make the total stress equalization, greatly reduce the tired service time of main shaft and base bearing, and inner sleeve force way and swivel head sealing means have been improved, the reliability of rotatory sealing and the life-span of seal have greatly been improved, improve the application life of top-drive drilling, solved the difficult problem that the refoulement of traditional top turns the easy inefficacy leakage of oil of sealing.
Description of drawings
Fig. 1 is the oil-well rig of the present utility model fixed top-drive drilling structural representations of two load passage wafer type back-up tong sleeves.
Primary clustering symbol description in the accompanying drawing:
Casing 1; Inner sleeve 2; Suspension body 3; Main shaft 4; Sleeve body 5; Wafer type back-up tong 6; Suspension ring 7; Elevator 8; Adpting flange 9.
The specific embodiment
Top-drive drilling of the present utility model, formed by casing and inner sleeve, main shaft, suspension body, adpting flange, wafer type back-up tong and sleeve body thereof, main shaft is sitting in the casing by base bearing, wafer type back-up tong and sleeve body thereof by suspension body and adpting flange be fixed on insert casing in put.
Be described further below in conjunction with accompanying drawing.
See also Fig. 1, the utility model is combined by casing 1, inner sleeve 2, suspension body 3, adpting flange 9, main shaft 4, sleeve body 5 and wafer type back-up tong 6.In casing 1, suspension body 3 is connected to inner sleeve 2 by adpting flange and consists of a load path inner sleeve 2 by interference fit, and main shaft 4 is sitting in casing 1 inner another passage of formation by base bearing, forms thus dual channel mode.Wafer type back-up tong 6 is connected to inner sleeve 2 by adpting flange 9 rather than is connected on the suspension body 3 through sleeve body 5.
In an embodiment, main shaft 4 is installed in casing 1 interior formation one load path by the base bearing in the casing 1, and when normal drilling well, drilling tool is connected on the main shaft 4, and this moment, all drilling tool weight all were applied on the main shaft 4, and were delivered to casing 1 by casing 1 inside main bearing; Suspension body 3 is connected on the inner sleeve 2 by adpting flange 9, consists of another load path, and in trip-out process, drilling tool acts on the elevator 8, is delivered to suspension body 3 and is delivered on the casing 1 by inner sleeve 2 by adpting flange 9 by suspension ring 7; Wafer type back-up tong 6 is connected to inner sleeve 2 by adpting flange 9 rather than is connected on the suspension body 3 through sleeve body 5, no longer with suspension body 3 rotations; When upper shackle, wafer type back-up tong 6 with drilling tool to being clipped in the middle of the back-up tong, large and the chucking power centering of chucking power, the back-up tong not easy to wear tooth that makes up tong, and on power when unloading be applied to equably on the inner sleeve 2 by sleeve body 5, and be delivered on the casing 1, rather than be applied on the suspension body 3, so that the lateral force of suspension body 3 when no longer bearing shackle reduced the wearing and tearing of sealing in the suspension body.
Owing to having adopted dual channel mode, make capable shunting, reduced the fatigue wear of main bearing piece, back-up tong is not fixed on the suspension body, so that during upper shackle in the suspension body sealing no longer bear the power of leaning to one side, greatly reduce the inefficacy of rotatory sealing, therefore greatly reduced swivel head place maintenance cost, reduce the top and drive the overhaul time interval, for drilling well improves the longer activity duration.
The above only is preferred embodiment of the present utility model.Do not breaking away under the principle of the present utility model; need not the other technologies feature that work just can be associated through reworked; can also make some modification and/or improvement, these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
