Abstract
The utility model relates to a petroleum and natural gas drilling device for oilfield, in particular to a slurry filter device. The slurry filter device comprises an upper cover, a lower cover, and a main body in the shape of a reversed truncated cone, wherein the upper cover is disposed above the main body; the lower cover is placed below the main body; at least one hole for communicating the outside and the inner cavity of the main body is formed on the surface of the main body; and a via-hole for communicating the outside and the inner cavity of the main body is also disposed on the upper cover. The slurry filter device has the advantages of simple structure and convenient assembly/disassembly, and can effectively filter off the slurry for the wireless inclinometer to prevent blockage.
Description
Technical field
The utility model relates to the probing development device of oil field oil, natural gas, relates in particular to the filtering slurry device.
Background technology
The drilling rod that uses in wireless drilling inclinometers drilling rod and other probings thereof is widely used in the petroleum drilling engineering.Because wireless drilling inclinometers uses drilling fluid to be signal transmission form, and the interior impurity of drilling fluid is more under the regular situation, stops up the inclinometer pulser easily.This programme provides a kind of filter, can well filter drilling fluid.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of simple in structure, for wireless drilling inclinometers effectively filters mud, prevents the filtering slurry device of the wireless drilling inclinometers that stops up.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of filtering slurry device, include loam cake, body, lower cover, and described body is the cylindrical shell of reverse frustoconic hollow, described loam cake is arranged on the top of body, and described lower cover is arranged on the below of body; On described body surface, be provided with extraneous at least one hole that is connected with the body internal cavity; Also be provided with the extraneous through hole that is connected with the body internal cavity on described on the cap body.
Further, described loam cake is a hollow rounding stage body, is embedded in the body top; Cavity in loam cake inside is separated into through hole by separating rib.
Further, cover under described and be provided with at least one hole.
Further, also include handle, be provided with the hole on the separation rib of described loam cake, described handle is located in the hole.
Further, the external surface at described loam cake also is provided with the collar.
The beneficial effects of the utility model are: simple in structure, easy installation and removal for wireless drilling inclinometers has effectively filtered mud, prevents to stop up.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the vertical view of loam cake of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, a kind of filtering slurry device includes loam cake 1, lower cover 2, body 3, and described body 3 is the reverse frustoconic cylindrical shell, and described loam cake 1 is arranged on the top of body 3, and described lower cover 2 is arranged on the below of body 3; On described body 3, be provided with the extraneous a plurality of holes 31 that are connected with the body internal cavity; Be provided with the extraneous through hole 11 that is connected with the body internal cavity on described on the cap body.Described loam cake 1 is a hollow rounding stage body, is embedded in body 3 tops; The cavity of loam cake 1 inside is separated into through hole 11 by separating rib 12.On described lower cover 2, be provided with a plurality of holes.Also include handle 4, be provided with hole 13 on the separation rib 12 of described loam cake, described handle 4 is located in the hole 13.External surface at described loam cake 1 also is provided with the collar 5.
The filtering slurry device is designed to round table-like, mainly be for the ease of putting into drilling tool, the drilling tool button-type is the taper button, the collar can just in time be put into drilling tool and hang over the space that the drilling tool top connection goes out, drill rod thread is a kind of special-purpose taper button, when two drilling rods joined, certain space can be left in inside, just in time can put into the filtering slurry device, and can not hinder other drilling tool of edge joint, each made a drilling rod after, when stab pipe, hold and carry handle the filtering slurry device is taken out, to pour out three circular holes of impurity from bottom, make up a joint in that the filtering slurry device is put into newly, all repeat top-operation at every turn when making up a joint, can ensure that mud meets instructions for use.Filter length is longer, as long as each the taking-up cleared up, just can not fill up impurity.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
