Description
Technical field
This utility model is related to a kind of drilling well, power drill for well workover tool.
Background technology
Petroleum resources are a kind of non-renewable resources, with the increasing of oil exploitation potentiation control DTH hammer bit, oil drilling, repair
Well operations gradually extend to deeper more complicated geology, and inclined shaft, horizontal well and service shaft are more and more, and common screw drilling tool is at these
When carrying out drilling well, workover treatment in Holes of Complicated Wells, as circulation fluid has the impurity such as sand grains, easily cause drilling tool blocking, make drilling tool without
Method is run, and maintenance frequency is frequent.
Utility model content
Technical problem to be solved in the utility model is：A kind of helicoid hydraulic motor defecator of good filtration effect is provided.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：Helicoid hydraulic motor defecator, bag
Include：Top connection and the lower contact being connected with filter shell lower end that filter shell is connected with filter shell upper end, described
The upper end of filter shell is internally provided with one-level chimney filter, and the upper end of the one-level chimney filter is oriented to chimney filter and filtration by one-level taper
The inwall of shell is connected, and is oriented on chimney filter in the one-level chimney filter and one-level taper and is evenly arranged with some one-level filter openings,
The one-level taper is oriented in the filter shell of chimney filter upper end and is provided with one-level filter screen, sets inside the lower end of the filter shell
Two grades of chimney filters are equipped with, the upper end of two grades of chimney filters is oriented to chimney filter by two grades of tapers and is connected with the inwall of filter shell,
Two grades of chimney filters and two grades of tapers are oriented on chimney filter and are evenly arranged with some two grades of filter openings, are oriented to chimney filter in two grades of tapers
Secondary screen is provided with the filter shell of upper end.
The utility model has the advantages that：Above-mentioned helicoid hydraulic motor defecator, using one-level filter screen, one-level filter opening, two grades of filters
Net and two grades of filter openings can carry out multistage filtering by impurity particle diameter to well liquid, can effectively prevent the impurity such as different-grain diameter gravel from passing through
Well liquid enters drilling tool, good filtration effect, it is ensured that the continuous and effective operation of drilling tool, while one-level taper is oriented to chimney filter and two grades of tapers
It is oriented to chimney filter to be oriented to well liquid, well liquid is quickly efficiently entering in chimney filter and filtered, using effect is good.
Description of the drawings
Structural representations of the Fig. 1 for this utility model helicoid hydraulic motor defecator.
In figure：1st, filter shell, 2, top connection, 3, lower contact, 4, one-level chimney filter, 5, one-level taper be oriented to chimney filter, 6, one
Level filter opening, 7, one-level filter screen, 8, two grades of chimney filters, 9, two grades of tapers are oriented to chimney filters, 10, two grades of filter openings, and 11, secondary screen.
Specific embodiment
Of the present utility model particular content is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, helicoid hydraulic motor defecator, including：Filter shell 1 be connected with 1 upper end of filter shell on connect
2 and the lower contact 3 that is connected with 1 lower end of filter shell, one-level chimney filter 4 is internally provided with the upper end of the filter shell 1,
The upper end of the one-level chimney filter 4 is oriented to chimney filter 5 by one-level taper and is connected with the inwall of filter shell 1, in the first-level filtering
Pipe 4 and one-level taper are oriented on chimney filter 5 and are evenly arranged with some one-level filter openings 6, are oriented to 5 upper end of chimney filter in the one-level taper
One-level filter screen 7 is provided with filter shell 1, two grades of chimney filters 8 is internally provided with the lower end of the filter shell 1, described two grades
The upper end of chimney filter 8 is oriented to chimney filters 9 by two grades of tapers and is connected with the inwall of filter shell 1, in two grades of chimney filters 8 and two grades
Taper is oriented on chimney filter 9 and is evenly arranged with some two grades of filter openings 10, in the filter shell that two grades of tapers are oriented to 9 upper end of chimney filter
Secondary screen 11 is provided with 1, and the mesh diameter of one-level filter screen 7 is more than the diameter of one-level filter opening 6, and the diameter of one-level filter opening 6 is big
In the mesh diameter of secondary screen 11, the mesh diameter of the secondary screen 11 is more than the diameter of two grades of filter openings 10.
When above-mentioned helicoid hydraulic motor defecator is used, top connection 2 is connected with pond by water pipe, lower contact 3 and drilling tool
It is connected.Well liquid is entered in filter shell 1 from top connection 2, carries out first time filtration through one-level filter screen 7 to well liquid, for the first time
Well liquid after filtration is rapidly entered in one-level chimney filter 4 through the guiding that one-level taper is oriented to chimney filter 5, through the of one-level filter opening 6
Secondary filter is turned again in filter shell 1, and the well liquid after second filtration completes third time through secondary screen 11 and filters, the
Well liquid after filtering for three times is rapidly entered in two grades of chimney filters 8 through the guiding that two grades of tapers are oriented to chimney filter 9, through two grades of filter openings 10
