Abstract
The utility model relates to wellbore construction filtering slurry technical field, particularly a kind of spiral fashion mud clarifier.This spiral fashion mud clarifier is the conical hollow chamber formed by some outer support bars, and described chamber wall depends on support bar inwall by filtering rod and spirals and surround, and is provided with space between adjacent head bar; The opening of described cavity bottom is greater than the opening of chamber roof; Described cavity bottom is provided with base, and described base fixes outer support bar.The utility model provides a kind of spiral fashion mud clarifier, and this apparatus structure is simple, easy and simple to handle; use reliable, can effectively filter mud impurity, protection drilling rod is not stabbed by high-pressure slurry liquid; solve drilling fluid and stab tool joint box hydrophthalmia inwall phenomenon, extend the application life of drilling rod.
Description
Technical field
The utility model relates to wellbore construction filtering slurry technical field, particularly a kind of spiral fashion mud clarifier.
Background technology
In actual well drilled construction, when drilling liquid flow will change the drilling fluid direction of motion after drill pipe filter, slurry liquid sinker bar female joint hydrophthalmia inwall, makes drilling rod be subject to stabbing of high-pressure slurry liquid, reduces the application life of drilling rod.
Utility model content
(1) technical problem to be solved
Technical problem to be solved in the utility model is to provide a kind of spiral fashion mud clarifier, change slurry liquid flow direction, reduce slurry liquid by pressure reduction during cleaner, make slurry liquid quickly through cleaner, solve the defect that high-pressure slurry liquid stabs tool joint box.
(2) technology contents
In order to solve the problems of the technologies described above, the utility model provides a kind of spiral fashion mud clarifier, it is characterized in that, described cleaner is the conical hollow chamber formed by some outer support bars, described chamber wall depends on support bar inwall by filtering rod and spirals and surround, and is provided with space between adjacent head bar;
The opening of described cavity bottom is greater than the opening of chamber roof; Described cavity bottom is provided with base, and described base fixes outer support bar.
Preferably, the space between described adjacent head bar is 5-7mm.
Preferably, the space between described adjacent head bar is 5.5mm.
Preferably, the cross section of described filtering rod is circular.
Preferably, described cleaner is placed in tool joint.
Preferably, described filtering rod is made up of Q235A Φ 6.5mm wire rod material.
(3) beneficial effect
The utility model provides a kind of spiral fashion mud clarifier, and this apparatus structure is simple, easy and simple to handle; use reliable, can effectively filter mud impurity, protection drilling rod is not stabbed by high-pressure slurry liquid; solve drilling fluid and stab tool joint box hydrophthalmia inwall phenomenon, extend the application life of drilling rod.
Accompanying drawing explanation
Fig. 1 is the utility model spiral fashion mud clarifier structural representation;
Fig. 2 is the utility model spiral fashion mud clarifier cross-sectional view.
Wherein:
1: outer support bar; 2: filtering rod; 3: base.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
As illustrated in fig. 1 and 2, the utility model provides a kind of spiral fashion mud clarifier, described cleaner is the conical hollow chamber formed by some outer support bars 1, and described chamber wall depends on support bar inwall by filtering rod 2 and spirals and surround, and is provided with space between adjacent head bar 2;
The opening of described cavity bottom is greater than the opening of chamber roof; Described cavity bottom is provided with base 3, and described base 3 fixes outer support bar 1.
Wherein, cleaner is set to the open chamber of conical hollow, at utmost to the impact force of drilling rod, the effect of protection drilling rod can be played by slowly-releasing part drilling fluid.
The quantity of this outer support bar 1 can be 3,4,6 or other quantity, and it can play the effect of supporting & stablizing filtering rod.
Wherein, the space between described adjacent head bar is 5-7mm.Preferably, the space arranged between adjacent head bar 2 is 5.5mm, the filtering foreign in mud can be gone out, and reduces mud stabbing drilling rod, extends the application life of drilling rod.
The cross section of filtering rod 2 is set to circle, and this form drag is little, and area of passage is large, drilling fluid resistance when flowing through cleaner being reduced, being beneficial to the circulation of drilling fluid, and can cushioning mud pressure, thus eliminating drilling fluid stabbing drilling rod.
Wherein, in order to ensure the application life of this cleaner, described filtering rod being set and being made up of Q235A Φ 6.5mm wire rod material, strengthening the stability of this cleaner performance.
The spiral fashion mud clarifier that the utility model provides, this apparatus structure is simple, easy and simple to handle; use reliable, can effectively filter mud impurity, protection drilling rod is not stabbed by high-pressure slurry liquid; solve drilling fluid and stab tool joint box hydrophthalmia inwall phenomenon, extend the application life of drilling rod.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
