Description
Technical Field
The invention relates to the technical field of mining devices, in particular to a four-wing anti-blocking horizontal head type drag bit with balls.
Background
A cutting bit with fins is commonly used in upper soft formations for petroleum drilling. There are double-winged, triple-winged, and quad-winged (as many as ten-winged drag bits also occur), with triple-winged drag bits being most commonly used. The bottom of the wing piece is provided with two steps (including an inner step, an outer step and a flat bottom) and the blade part of the wing piece is welded with hard alloy or diamond. Drag bits are again divided into two categories, coring and non-coring, as desired. The method is applicable to the stratum: extremely soft, medium hard.
The drag bit is the earliest bit used in rotary drilling, has simple structure, convenient manufacture and low cost, and is used for drilling soft strata such as mudstones, shale and the like with the drillability reaching 4 levels. Because the bearing area of the bit is large, the bit is difficult to cut into when drilling hard stratum or hard interlayer with staggered hardness, and the drilling efficiency is low. With the successful development of the inserted drag bit and the diamond drag bit, the drilling efficiency and the application range of the drag bit are improved and expanded.
The prior art discloses a drag bit (CN 201510513230.2), wherein a plurality of scraping blades are arranged at the bottom of a cutter head, a cutting edge is arranged on the scraping blades, a plurality of cutting blocks are arranged at the edge of the cutter head, and a plurality of impregnated teeth are arranged on the cutting blocks. The present invention provides a versatile drill bit; the new drill bit is added, so that the drill bit can be better adapted to various geological conditions; the cutting area is increased, and the mining efficiency is improved; and the dust generation amount in the mining process is reduced.
The prior art also discloses a drag bit device (CN 201710549653.9), which relates to the technical field of petroleum engineering drilling, the drag bit device comprising: the body is provided with heating power efflux unit and the reaction chamber that is linked together with heating power efflux unit on the body, heating power efflux unit includes: the device comprises a through hole formed in a body, a first spring arranged in the through hole, a first telescopic pipe propped against the first spring, a second spring arranged in the first telescopic pipe and a second telescopic pipe, wherein the upper end of the first spring can be fixed with the body, the second spring is connected with the second telescopic pipe, the second telescopic pipe can slide in the first telescopic pipe so that the lower end of the second telescopic pipe extends out of the through hole, and a reaction cavity is used for generating thermal jet fluid and conveying the thermal jet fluid to a thermal jet unit; the body is also provided with cutting teeth; and the thermal jet ignition unit is connected with the reaction cavity and is used for igniting the reaction cavity.
Meanwhile, the prior art also discloses a rotary drag bit including a bit body (CN 200880006237.3) having a face and an axis, a plurality of blades extending radially and longitudinally outwardly from the face, and at least one split cutter set. The split cutter set includes a plurality of cutters, wherein at least two of the cutters are primary cutters and/or cutting cutters located on different blades of the plurality of blades. The pair of main cutters and/or cutting cutters of the split cutter set may be positioned at substantially the same radial distance from each other or at substantially the same longitude or elevation on the drill bit as each other relative to a centerline or axis of rotation of the drill bit, or follow substantially the same rotational or helical cutting path as each other. In addition, at least one of the auxiliary cutters may be positioned at substantially the same radial distance from the center line or axis of rotation of the drill bit as the one or both of the main cutters and/or the cutting cutters or at substantially the same bit longitude or elevation as the one or both of the main cutters and/or the cutting cutters, or follow substantially the same rotational or helical cutting path as the one or both of the main and/or cutting cutters. The cutters of the split cutter set may be constructed and positioned to provide increased bit life and reduced stress on the cutters.
