Abstract
The utility model provides a boring rod filter with a protective cover. The boring rod filter is used for filtering impurities carried by drilling fluid during the well-drilling process of petroleum and natural gas. The boring rod filter with the protective cover comprises a bolt, a fixed joint, a fixed frame, a fixed seat, a nut, a fixed sleeve, the filter, a cover, a conical protrusion block, a small filter plate and a large filter plate. The bolt passes through the central hole at the upper end of the fixed joint and is connected with the nut; two ends of the fixed frame are respectively welded with the fixed joint and the fixed seat; the fixed seat is welded with the filter and is connected with the fixed sleeve by a thread simultaneously; the fixed sleeve is welded with the cover; the filter is welded with the small filter plate; the cover is welded with the large filter plate; and the conical protrusion block passes through the central hole of the small filter plate and is welded with the large filter plate. In the utility model, the impurities in the drilling liquid during the well-drilling process can be filtered, the boring rod can be well protected by the protective function of the cover, the washing of the drilling liquid on the boring rod can be avoided, the service life of the boring rod can be prolonged, and the occurrence of the underground mining accident is reduced.
Description
Technical field
A kind of drilling rod filter with protective cover is used for the oil and gas well drilling process and filters the impurity that drilling fluid carries, and belongs to oil and gas well drilling equipment manufacturing technology field.
Background technology
In the oil and gas well drilling operation, the drilling rod that generally adopts under kelly bar one of termination to have the drilling rod filter filters the impurity in the drilling fluid.Be directly to wash away the drilling rod inwall by the drilling fluid behind the drilling rod filter in the past, and caused drilling rod to damage easily, influenced the intensity and the life-span of drilling rod.
Summary of the invention
The purpose of this utility model is not have protective device to be washed away the problem of damage easily by the drilling fluid by the drilling rod filter at present drilling rod inside, designs a kind of drilling rod filter with protective cover, stops drilling fluid directly to wash away drilling rod.
The technical solution of the utility model is: the utility model comprises bolt, anchor tip, fixed mount, holder, nut, fixed cover, filter, cover, circular cone projection, little filter plate, big filter plate.
Bolt passes anchor tip upper end centre bore and is connected with nut, weld with anchor tip and holder respectively at the fixed mount two ends, holder and filter welding, be threaded with fixed cover simultaneously, fixed cover and cover welding, filter and the welding of little filter plate, cover and big filter plate welding, circular cone projection seat are gone into little filter plate centre bore and are welded with big filter plate.
Need check or when changing filter, dismantle holder and fixed cover be threaded and on carry bolt, anchor tip, holder, fixed cover and filter and little filter plate are drawn out together.Drilling fluid by the time, each aperture flows out on filter and the little filter plate, the drilling fluid that flows out from little filter plate flows to big filter plate along the annular clearance between filter and the cover, flows out big filter plate at last, thereby has avoided drilling fluid washing away drilling rod.
The beneficial effects of the utility model are: can filter the impurity in the drilling fluid in drillng operation, and utilize the protective effect of cover to protect drilling rod well, prolong the drilling rod life-span, reduce the generation of down-hole accident.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Among Fig. 1,1 is bolt, and 2 is anchor tip, and 3 is fixed mount, and 4 is holder, and 5 is nut, and 6 is fixed cover, and 7 is filter, and 8 is cover, and 9 is the circular cone projection, and 10 is little filter plate, and 11 is big filter plate 11.
The specific embodiment
Bolt 1 passes anchor tip 2 upper end centre bores and is connected with nut 5, weld with anchor tip 2 and holder 4 respectively at fixed mount 3 two ends, holder 4 and filter 7 welding, be threaded with fixed cover 6 simultaneously, fixed cover 6 and cover 8 welding, filter 7 and 10 welding of little filter plate, cover 8 and big filter plate 11 welding, 9 of circular cone projections are gone into little filter plate 10 centre bores and are welded with big filter plate 11.
Drilling fluid by the time, each aperture flows out on filter 7 and the little filter plate 10, the drilling fluid that flows out from little filter plate 10 flows to big filter plate 11 along the annular clearance between filter 7 and the cover 8, flows out big filter plate 11 at last, thereby has avoided drilling fluid washing away drilling rod.
