Description
Technical field
The present invention relates to oil drilling equipment fields, more particularly to a kind of protective device of underground resistivity female thread.
Background technology
Currently, because oil-well drilling equipment resistivity ontology be it is integrated, and box face repair button surplus it is few, resistivity female thread
Dismount the frequency it is more, box face easy damaged, it is easy to cause whole resistivity to be scrapped, greatly shorten resistivity service life and
Loss is very big.
Invention content
The technical problem to be solved by the invention is to provide a kind of protective devices of underground resistivity female thread.
The technical solution adopted in the present invention is a kind of protective device of underground resistivity female thread, including, protection pipe nipple,
Wet joint male connector, core extension rod, resistivity and current divider；The protection pipe nipple passes through oil standard button-type NC50 and resistivity
Female thread connects；One end of the core extension rod and wet joint male connector, the other end of core extension rod are connect with current divider.
The core extension rod include upper short outer barrel, centralizer and under short outer barrel；The wet joint male connector is installed on core
Extend on the upper short outer barrel of rod piece, current divider is mounted on core and extends under rod piece on short outer barrel.
The protection pipe nipple peripheral surface is four spiral flow passage types, tungsten carbide button's block in four spirals.
After the short section Xiu buttons of protection, the upper short outer barrel that core extends in rod piece can synchronize shortening, the phase after being detained with Xiu
Protection pipe nipple matches.
The invention has the advantages that due to adding core extension rod and protection pipe nipple, the dismounting of resistivity female thread is reduced
The female thread of the frequency, effective protection resistivity extends resistivity service life from damage；After button is repaiied in protection pipe nipple damage, core
Extension rod piece, which can synchronize to repair, buckles shortening, repeatedly uses, cost-effective.The device is easy to operate, has prodigious practicality
Meaning.
Description of the drawings
Fig. 1 is resistivity female thread protective device installation diagram of the present invention.
In figure：
1, protection pipe nipple 2, wet joint male connector 3, upper short outer barrel
4, centralizer 5, under short outer barrel 6, resistivity
7, current divider.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1, the protective device of resistivity female thread in underground of the present invention, including, protection pipe nipple 1, wet joint male connector 2, core
Extension rod, resistivity 6 and current divider 7；The protection pipe nipple 1 is connected by oil standard button-type NC50 with 6 female thread of resistivity；Institute
The one end and wet joint male connector 2, the other end of core extension rod for stating core extension rod are connect with current divider 7.
The core extension rod include upper short outer barrel 3, centralizer 4 and under short outer barrel 5；Centralizer 4 can play instrument and help
Positive interaction avoids instrument from causing damage of components in underground strenuous vibration.The wet joint male connector 2 is installed on core and extends rod piece
Upper short outer barrel 3 on, current divider 7 is mounted on core and extends under rod piece on short outer barrel 5, that is, core extension rod is by wet joint public affairs
First 2 and current divider 7 connected by screw buckle.1 peripheral surface of the protection pipe nipple is four spiral flow passage types, is inlayed in four spirals
Embedding hard alloy blocks prevent resistivity instrument ontology from being worn caused by frequently being contacted with the borehole wall, play resistivity abrasionproof purpose.Institute
After stating protection pipe nipple 1 Xiu buttons, the upper short outer barrel 3 that core extends in rod piece can synchronize shortening, the protection pipe nipple after being detained with Xiu
Match.
The present invention due to adding core extension rod and protection pipe nipple, protection pipe nipple with after resistivity use, it is not necessary to tear open
It opens, the screw buckle caused by frequently dismounting is avoided to damage, the female thread of effective protection resistivity extends resistivity and use the longevity from damage
Life；After protection pipe nipple repaiies button, core extension rod piece, which can synchronize to repair, buckles shortening, can match protection pipe nipple after repairing button.The device
It is few to solve resistivity ontology Mu Kou Xiu button surpluses, easily leads to the defect that resistivity is scrapped, it is easy to operate, there is prodigious practicality
Meaning.
It is worth noting that protection scope of the present invention is not limited to above-mentioned specific example mode, it is according to the present invention
Basic fundamental is conceived, it is also possible to which the purpose of the present invention may be implemented in basically same structure, as long as those of ordinary skill in the art
Need not move through creative work, you can the embodiment associated all belongs to the scope of protection of the present invention.
