Abstract
A fluid pulse valve and a method of using the fluid pulse valve are disclosed. The fluid pulse valve comprises an outer housing, a rotor contained within the outer housing, a stator tube surrounding the rotor and adjacent to the outer housing, the stator tube comprising a plurality of slots, and a closer coaxially and rotationally coupled to the rotor and at least a portion of the closer in line with the plurality of slots. As the closer rotates, the closer covers and uncovers the plurality of slots to create a pulse.
Claims26
A fluid pulse valve, comprising:
- an outer housing;
- a rotor contained within the outer housing;
- a ceramic stator tube surrounding the rotor and adjacent to the outer housing, the stator tube comprising a plurality of slots;
- and
- a ceramic closer rotationally coupled to the rotor and at least a portion of the closer in line with the plurality of slots;
- wherein as the closer rotates, the closer covers and uncovers the plurality of slots to create a pulse.
A method of vibrating a drill string, comprising:
- providing a bottom hole assembly (BHA);
- providing a fluid pulse valve positioned uphole of the BHA, the fluid pulse valve comprising:
- an outer housing;
- a rotor contained within the outer housing;
- a ceramic stator tube surrounding the rotor and adjacent to the outer housing, the stator tube comprising a plurality of slots;
- and
- a ceramic closer rotationally coupled to the rotor and at least a portion of the closer in line with the plurality of slots;
- and
- passing fluid through the fluid pulse valve to the BHA, wherein the fluid forces the closer to rotates, which covers and uncovers the plurality of slots to create a pulse, thereby vibrating the drill string.
