Abstract
A jet nozzle for oilfield drill bits which utilizes a novel orifice configuration to allow for smaller sizes without the risk of debris clogging typically associated with smaller sized jet nozzles. The nozzle's orifices are arranged such that the larger of the paired orifices facilitates the unplugging of the smaller orifice when it may become clogged with debris from the mud used in the drilling process. The nozzles may be utilized with existing drilling equipment and may further enable the realization of smaller jet nozzle sizes.
Claims6
A drill bit jet nozzle apparatus comprising:
- a nozzle body;
- a small orifice;
- a large orifice;
- a connecting slit;
- a socket connection;
- and
- indexable threading;
- wherein:
- the nozzle body is generally cylindrical comprising:
- a face at its anterior end,
- a cavity formed through its interior, and
- an opening at its posterior;
- the socket connection is formed from the perimeter of the nozzle body's face;
- the indexable threading is formed on the rounded sides of the nozzle body at its posterior;
- the small orifice is a through hole on the nozzle body's face;
- the large orifice is a through hole on the nozzle body's face;
- the large orifice is larger than the small orifice;
- the connecting slit is a through hole which connects the small orifice at one end and the large orifice at its opposite end;
- and
- the inlet edges of the small orifice, large orifice, and connecting slit are each honed to a sharp edge on the internal surface of the nozzle.
