Abstract
The utility model aims to overcome the defects in the prior art and provide a replaceable sleeve eccentric stabilizer. The eccentric stabilizer is characterized in that a replaceable sleeve is arranged on the outer circular surface of the eccentric stabilizer, the replaceable sleeve is in threaded connection with the eccentric stabilizer, and a hard alloy abrasion-resistant block is arranged on the outer circular surface of the replaceable sleeve. Compared with the prior art, the eccentric stabilizer has the advantages of simple structure, low manufacturing cost, convenience in construction and operation, firmness and durability.
Description
Technical field
The utility model is specifically related to a kind of replaceable sleeve eccentric stabilizer.
Background technology
In oil, gas drilling engineering, some position of the drill string of being everlasting connects one or several stabilizers, in order to control well track.Stabilizer is an easily worn part, and the existing stabilizer in market is for increasing its abrasion resistance at the external surface processing muscle band of stabilizer, and its shortcoming is just to have scrapped the increase drilling cost when the muscle band whole stabilizer that is worn to a certain degree the time.
Summary of the invention
The purpose of this utility model is in order to overcome defective of the prior art, a kind of replaceable sleeve eccentric stabilizer to be provided.
The purpose of this utility model is achieved in that
A kind of replaceable sleeve eccentric stabilizer is characterized in that, installs on the periphery of eccentric stabilizer and changes cover, and described replacing cover adopts spiral shell to be connected with eccentric stabilizer.
Described replacing cover periphery is welded with the hard alloy wear resistance piece.
The utility model compared with prior art has simple in structure, low cost of manufacture, and constructing operation is convenient, robust advantage.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the 1-eccentric stabilizer, 2-changes cover, 3-hard alloy wear resistance piece, 4-screw.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of replaceable sleeve eccentric stabilizer described in the utility model, formed by eccentric stabilizer 1 and the replacing cover 2 that is installed on eccentric stabilizer 1 periphery, changing cover 2 usefulness screws 4 is connected with eccentric stabilizer 1, the periphery of changing cover 2 is welded with three hard alloy wear resistance pieces 3, and hard alloy wear resistance piece 3 has increased the abrasion resistance of this stabilizer.
When eccentric stabilizer 1 after the work regular period, change hard alloy wear resistance piece 3 on the cover 2 and be worn to can not continue to use the time, only need to change cover 2 and can continue to use.
Claims (2)
1. a replaceable sleeve eccentric stabilizer is characterized in that, installs on the periphery of eccentric stabilizer and changes cover, and described replacing cover adopts spiral shell to be connected with eccentric stabilizer.
2. a kind of replaceable sleeve eccentric stabilizer as claimed in claim 1 is characterized in that, described replacing cover periphery is welded with the hard alloy wear resistance piece.
