Abstract
The utility model relates to a reverse hole marking slip for well drill start, comprising a main slip and a minor slip. The interiors of the main slips and the minor slips are provided with reverse-conical inner holes; the surface of each inner hole is provided with a plurality of tilting dovetail grooves whose interiors are provided with slip teeth; the main slip and the minor slip are combined through bolts and keys; the reverse-conical surface of the lower end of the main slip and the conical inner hole of a rotary disc for friction combination. The utility model has the advantages of simple structure and convenient operation, and the continuous operation of the reverse hole marking when the drill starts can be realized.
Description
The utility model belongs to the drilling machinery technical field.
In the trip-out operation of drilling well, use general portable slips, regular meeting runs into a lot of difficulties.Drilling tool is made up of many drilling rods that link together and drill bit.Between drilling rod and the drilling rod joint is arranged.Slips is clamped drilling rod, is arranged in rotating disk, and rotating disk drives slips, the rotation of transmission drilling tool.In the trip-out operation, when up mentioning drill bit,, need rotation back reaming limit, limit upwards mention drilling tool if when meeting with obstruction thing.Owing to there is joint to connect between the drilling rod, when upwards mentioning drilling tool, when joint passes through slips, need shutdown that portable slips is mentioned and unload, the new clothes of laying equal stress on pull out of hole again to the following position of the joint of drilling tool again.Joint moves one whenever, just need be by this program repetitive operation once.Operation sequence is interrupted, and is very loaded down with trivial details, time-consuming.
It is a kind of in the trip-out operation that the purpose of this utility model is to provide, and wedging drilling rod wedging joint is automatically again automatically realized the slips of continuous trip-out operation.
The purpose of this utility model is achieved in that a kind of drilling well trip-out reverse marking hole slip, comprise main slips and secondary slips, main slips and secondary slips are synthetic by two, the heart all has the turbination endoporus therein, the endoporus internal diameter, has several to diagonally distribute from top to bottom and has the oblique dovetail groove of certain angle at the turbination bore area greater than the tool joint external diameter, respectively embed a slip insert in each oblique dovetail groove, slip insert can tiltedly slide up and down in the dovetail groove.Secondary slips is positioned on the main slips, is connected with bolt between main slips and the secondary slips, and the key of gearing has been arranged between the lower surface of secondary slips and main slips upper surface.Combine for friction between the turbination external surface of main slips lower end and the turbination endoporus of rotating disk.In trip-out process, when drilling rod is arranged in main slips and secondary slips endoporus, the slip insert of main slips and secondary slips is positioned at the upper/lower positions of oblique dovetail groove, drilling rod is relied on the power effect for support by the slip insert wedging, rotating disk transmission master's slips and secondary slips, drive drilling rod by slip insert and rotate, suspension hook is sling and is moved on the drilling tool simultaneously, makes the drill bit back reaming that makes progress.Move on suspension hook is sling drilling tool, when making joint enter main slips endoporus from bottom to top, the slip insert of joint edges roof pressure master slips makes and moves on it and the wedging joint, and the slip insert of secondary slips wedging drilling rod still.When joint is upwards crossed main slips endoporus and when entering secondary slips endoporus, the make progress slip insert of the secondary slips of roof pressure of joint makes and move on it and the wedging joint, and the slip insert of main slips is displaced downwardly to bottom the wedging drilling rod because joint has been removed under action of gravity.So hocket, in the trip-out operation, must not mention and unload lower slips, the continued operation of the operation that just can realize pulling out of hole.
The utility model has the advantages that simple in structurely, easy to operate, can make major and minor slips replace automatic wedging drilling rod and joint and realize proposing the brill continued operation.
Fig. 1 is a structure chart of the present utility model, and Fig. 2 is the vertical view of major and minor master watt turbination endoporus.
Fig. 1, Fig. 2 are described as follows: 1 is main slips, and 2 is secondary slips, and 3 is rotating disk, and 4 is the turbination endoporus, and 5 is oblique dovetail groove, and 6 is slip insert, and 7 is bolt, and 8 is driving key, and 9 is drilling rod, and 10 is joint.
Claims (1)
1, a kind of drilling well trip-out reverse marking hole slip, it is characterized in that comprising main slips (1), secondary slips (2), main slips (1) and secondary slips (2) are synthetic by two, the heart all has turbination endoporus (4) therein, several oblique dovetail grooves (5) that diagonally distributes from top to bottom and have certain angle are arranged on the surface of turbination endoporus (4), in each oblique dovetail groove (5), respectively embed 1 slip insert (6) that can in oblique dovetail groove (5), slide up and down; Secondary slips (2) is positioned on the main slips (1), is connected with bolt (7) between main slips (1) and the secondary slips (2), between secondary slips (2) lower surface and main slips (1) upper surface driving key (8) is arranged; Combine with friction between the turbination external surface of main slips (1) lower end and the turbination endoporus of rotating disk (3).
