Description
Technical field
The utility model relates to a kind of drilling fluid filter.
Background technology
Rig is when holding brill directional well (containing oblique horizontal well and straight well section), to enter with circulation of drilling fluid for preventing ultra-specification solid foreign materials and particle and cause measure error bottom drill string thus make drill bit depart from target bearing, then drilling fluid needs to filter before entering drill string.
At present, under inclined shaft, horizontal well and complicated geological environment condition, drilling well increases, and Drill Pipe Washout phenomenon happens occasionally, and some drilling rod or even the generation thorn leakage phenomenon when undercoating does not come off, cause very large economic loss.Cause the main cause of this phenomenon be because, in order to prevent impurity in drilling fluid and foreign object damage orientation device, operating personnel placed tubular porous cleaner in drilling rod female end, thus causes the erosion of drilling rod generation herein, thus causes the generation that thorn leaks phenomenon.
Utility model content
In order to overcome the deficiency in background technology; the utility model discloses a kind of drilling fluid filter; the utility model by increasing the screen pack of multilayer unlike material in column tube; not only increase the filter efficiency of drilling fluid; pass through the rubber sleeve of column tube and column tube outside simultaneously; better protection is defined to drilling rod junction, substantially prolongs the application life of drilling rod.
Realize the technical solution of the utility model as follows:
A kind of drilling fluid filter, comprise column tube and expanding ring, the upper end outer edge surface of column tube is provided with expanding ring, external screw thread is provided with at the expanding ring outer edge surface of described column tube upper end, wire screen is provided with in column tube inside, be provided with filter-cloth filtering net in the below of described wire screen, be provided with yarn screen pack in the below of described filter-cloth filtering net, the outer edge surface of column tube is provided with gum sleeve.
Described drilling fluid filter, the inwall both sides in column tube are provided with multiple buckle.
Described drilling fluid filter, described buckle is the folding structure of del.
Described drilling fluid filter, described wire screen, filter-cloth filtering net and yarn screen pack are demountable structure.
Described drilling fluid filter, the expanding ring of described column tube upper end is threaded with the internal thread in drilling rod by external screw thread.
Described drilling fluid filter, the diameter of described column tube should be less than the externally threaded annular diameters of drilling rod.
The beneficial effects of the utility model are, a kind of drilling fluid filter described in the utility model, by placing column tube in drilling rod internal connection, effectively avoid the erosion of drilling fluid to drilling rod junction; By installing gum sleeve at column tube outer edge surface, making its drilling rod junction inwall and fluid isolation, avoiding corrosion; By arranging the screen pack of multilayer unlike material in column tube inside, make to filter respectively on corresponding screen pack different foreign matters or impurity in filter process, its filter efficiency is significantly improved, avoid foreign matter or impurity plug filter hole; The utility model structure is simple, easy for installation, greatly improves the filter efficiency of drilling fluid, extends the application life of drilling rod.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is internal construction schematic diagram of the present utility model.
Fig. 2 is external structure schematic diagram of the present utility model.
Fig. 3 of the present utility modelly installs and uses schematic diagram.
In figure: 1. expanding ring, 2. external screw thread, 3. column tube, 4. wire screen, 5. filter-cloth filtering net, 6. yarn screen pack, 7. gum sleeve, 8. drilling rod, 9. buckle.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
By reference to the accompanying drawings 1, structure given by 2 or 3, a kind of drilling fluid filter, comprise column tube 3 and expanding ring 1, the upper end outer edge surface of column tube is provided with expanding ring 1, external screw thread 2 is provided with at expanding ring 1 outer edge surface of described column tube 3 upper end, wire screen 4 is provided with in column tube 3 inside, filter-cloth filtering net 5 is provided with in the below of described wire screen 4, yarn screen pack 6 is provided with in the below of described filter-cloth filtering net 5, described wire screen 4, filter-cloth filtering net 5 and yarn screen pack 6 are demountable structure, inwall both sides in column tube 3 are provided with multiple buckle 9, described buckle 9 is the folding structure of del, the outer edge surface of column tube 3 is provided with gum sleeve 7, the expanding ring 1 of described column tube 3 upper end is threaded with the internal thread in drilling rod 7 by external screw thread 2, the diameter of described column tube 3 is less than the externally threaded diameter of drilling rod 7.
Implement drilling fluid filter described in the utility model, during use, by wire screen 4, filter-cloth filtering net 5 and yarn screen pack 6 are by the buckle 9 be placed on successively in column tube 3, gum sleeve 7 is enclosed within the outer edge surface of column tube 3, by the external screw thread 2 on expanding ring 1 outer edge surface of column tube 3 upper end, by the utility model knob in drilling rod 8, diameter due to column tube 3 is less than the diameter of inner pipe of drilling rod 8, so there is gap between the inner surface of the outer edge surface of column tube 3 and drilling rod 8, another drilling rod 8 passes through the gap between the outer edge surface of column tube 3 and the inner surface of drilling rod 8 by the external screw thread of front end, formed with drilling rod 8 and be threaded, column tube 3 is then fitted in two drilling rod 8 internal connections and inwall, formed and combine comparatively closely, after installing, can normally use, during use, drilling fluid is flowed by the cavity of drilling rod 8 inside, when flowing to junction, flow in column tube 3, by multiple screen packs of column tube 3 inside, drilling fluid is effectively filtered, due to the existence of the gum sleeve 7 of column tube 3 and outside, its drilling fluid cannot be flowed touch the junction of two drilling rods 8, avoid the corrosion to drilling rod 8 and erosion, substantially prolongs the application life of drilling rod, after finishing using, only drilling rod 8 need be disassembled, column tube 3 knob be got off, ejects column tube 3 from bottom by screen pack, screen pack is cleaned, after cleaning, be installed in column tube 3, can again come into operation.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
