Description
Technical field
The utility model relates to a kind of aid using in a kind of Process of Oil Well Drilling, and particularly a kind of drilling well is filtered pipe nipple with down-hole.
Background technology
In oil and gas well drilling process, MWD wireless drilling instrument application is more and more extensive, in the time using MWD wireless drilling instrument, must ensure that mud is clean.Be all to clean mud by boring rod filter in the past, made at every turn in stacks, all will pick and place boring rod filter one time.Picking and placeing this process of boring rod filter has increased the many amounts of labour of oil worker, boring rod filter also likely occurs simultaneously and be placed on and in drilling rod, forget the situation of getting, and serious consequence can cause that drilling rod pierces through, the accident of drillling tool twisting off.
Chinese patent literature number is 201363100, patent name is " anti-clogging pup joint for drill rod ", discloses the anti-clogging pup joint for drill rod that a kind of petroleum industry is used, and is connected on drilling rod tubing string, prevent that corrosion fragment, chip in drilling rod from stopping up drilling rod tubing string, ensures normally carrying out of workover treatment.Anti-clogging pup joint for drill rod comprises top connection, lower contact, filter mechanism and adsorbing mechanism, adsorbing mechanism is arranged between top connection and lower contact, and filter mechanism is connected with adsorbing mechanism, forms precipitation chamber in top connection, the corrosion chip of adsorption precipitation, fragment, prevent from stopping up drilling rod tubing string.It is mainly the filtration that solves the iron rust of drilling rod inwall generation, and is not for the filtering slurry in drilling process, and its purposes is different, and design principle is different.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has; provide a kind of drilling well to filter pipe nipple with down-hole; in drillng operation, can filter mud; protection MWD wireless drilling instrument; substitute existing drill pipe filter; the amount of labour that has alleviated oil worker, has improved bit speed.
Its technical scheme is: be made up of filter core joint, filter core and pipe nipple outer tube, filter core joint box end has a plane shoulder, and pin end has a plane shoulder and a bevelled shoulder; Described filter core is made up of filter core body and filter core base, and filter core body and filter core base are mounted on pipe nipple outer tube bore; Filter core body seal face contacts with the plane shoulder of filter core joint box end.
Above-mentioned filter core floor installation, at pipe nipple outer tube bore, to carrying out rectification through the mud of filter core body, and makes filter core body keep middle position in filtration pipe nipple.
Above-mentioned filter core body is connected with filter core base by thread, for filter core body and filter core base are disassembled.
There is large flowing hole the upper end of above-mentioned filter core body, and bottom is provided with little flowing hole.
Above-mentioned filter core body adopts bar machine to form, and is provided with reducing position in filter core body centre position.
The bottom of above-mentioned filter core body is provided with connector, is connected and fixed by connector and filter core base.
The beneficial effects of the utility model are: first can filter the bulk impurity in drilling fluid, guarantee MWD wireless drilling instrument is normally worked in down-hole; Secondly can avoid bit port to stop up; Can solve existing drill pipe filter damage drilling rod box hydrophthalmia inwall, cause the short problem of drilling life of drill pipe, meanwhile, in the time of the stifled full impurity of filter core body, mud can pass through from larger flowing hole, avoids the problem pulling out of hole due to the stifled full impurity of filter core simultaneously.Finally, make can filter mud in drillng operation, protection MWD wireless drilling instrument, substitutes existing drill pipe filter, has alleviated oil worker's the amount of labour, has improved bit speed.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: filter core joint 1, filter core 2, filter core body 2.1, filter core base 2.2, pipe nipple outer tube 3.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model is made up of filter core joint 1, filter core 2 and pipe nipple outer tube 3, and filter core joint 1 box end has a plane shoulder, and pin end has a plane shoulder and a bevelled shoulder; Described filter core 2 is made up of filter core body 2.1 and filter core base 2.2, and filter core body 2.1 and filter core base 2.2 are mounted on pipe nipple outer tube 3 inner chambers; Filter core body 2.1 seal faces contact with the plane shoulder of filter core joint 1 box end.
Wherein, filter core base 2.2 is arranged on pipe nipple outer tube 3 inner chambers, to carrying out rectification through the mud of filter core body 2.1, and makes filter core body 1 keep middle position in filtration pipe nipple, avoids because the accident of bad drilling tool of the unstable thorn of mud flow occurs.
In addition, filter core body 2.1 and filter core base 2.2 are threaded connection, and in the time of the interior stifled full impurity of filter core body 2.1, filter core body 2.1 and filter core base 2.2 can be disassembled, and impurity can easily be got rid of from link aperture.
There is large flowing hole the upper end of filter core body 2.1, and bottom is provided with little flowing hole, avoids because the stifled full impurity of filter core body 2.1, pump pressure raise and pull out of hole.Filter core body 2.1 adopts bar machine to form, and is provided with reducing position in filter core body 2.1 centre positions, alleviates the erosion to filter core body 1 inwall of mud through filter core body 2.1.The bottom of filter core body 2.1 is provided with connector, is connected and fixed by connector and filter core base 2.2.
The advantage the utlity model has is as follows:
