专利摘要:
A rotary drilling tool has a plurality of rollers, each of which is provided with a specific pair of jets comprising a flushing jet having a downwardly directed component and an upwardly directed eduction jet, these jets being formed on both sides of the plane defined by the bit axis and the roller axis, and the flushing jet being inclined by at least 20 DEG on said plane and substantially tangent to the active part of the roller.

专利说明:

The invention relates to rock breeding tool, namely roller cone bits.
Known drilling cone bit, comprising a housing, cones and a flushing system, including ejection, peripheral and central flushing units 1.
It is also known to drill a roller bit, which contains a housing with inclined trunnions on which rotating sharaoo1Ki are mounted with a cutting blade and elements located on the peripheral part of the hull, the washing and ejection nozzles directed in opposite directions 2j,
The disadvantage of izveshnyh bits is poor cleaning of the bottom of the sludge, which reduces the efficiency. chisels in general.
The purpose of the invention is to improve the cleaning of the slalom due to the creation of a forced flow of liquid -, each of them.
The goal is achieved by the fact that in a drill bit there is a housing with acrylic trunnions on which rotating cones with cutting elements are mounted and the ejection nozzles directed in opposite directions are located in the peripheral part of the hull and ejection nozzles are combined in opposite directions. NUMBER of cones and are located on both sides relative to the axial plane of the body passing through the axis of the cone, and the opening axis of each washing nozzle is inclined by at least 20 h Eva plane of the body.
FIG. 1 shows a chisel, general / axonomic view, FIG. 2go, side view.
The drill bit includes a housing 1 with two legs 2, on the pins of which the roller cutters 3 are mounted with cutting
elements, for example, in the form of teeth. The bit is connected to a drill string 5 or a downhole motor with a threaded nipple 4. In the bit housing 1 there is a cavity b communicating with the drill pipe cavity washing 7 and ejection 8 nozzles. The washing nozzles 7 are located near the cones 3 and are oriented in the direction of their rotation, while the angle oi formed by the axis UU of the nozzle 7 and the plane XX passing through the axis of the cone and the bit axis is not less than 20. The nozzles 7 can be round or slit hole. The slit shape is more preferable. The ejection nozzles 8 are also connected to the cavity 6 of the housing 1 and the opposite direction with respect to the washing nozzles 7, the nozzles 7 and 8 being paired up by the number of the cones 3 and located on both sides relative to the plane XX. The ejection nozzles 8 form a suction jet directed into the space between the column 5 and the walls of the well. Nozzles 7 and 8 are connected to cavity 6 by profiled channels 9 and 10, which ensures a reduction in head loss.
In operation, the bit is injected through, washing the nozzle 7, the liquid displaces the particles of the soil destroyed by shingles 3. The liquid enriched with sludge is carried into the annular space 11 under the action of the discharge created by the ejection nozzles B.
A similar washing pattern can be used in bits with any number of cutters, and not just with two cutters, as shown in fng 1 and 2.
The application of the proposed bit will provide the best cleaning of the bottom of the sludge due to the creation of a forced flow of fluid under each cone.
