Abstract
The present disclosure is directed to an apparatus for use with a vibratory tool in a bottom hole assembly to enhance the vibration of the bottom hole assembly. The apparatus includes at least one spring mechanism and a fluid passageway disposed within a housing. The apparatus can be tuned and/or parts of the bottom hole assembly can be manipulated to match the frequency of the vibratory tool and/or the frequency of the vibratory tool can be tuned to match the vibrational frequency of the bottom hole assembly and the apparatus.
Claims28
A vibration enhancing apparatus, the apparatus comprising:
- a first end;
- a second end;
- a passageway disposed at least partially within a housing to permit fluid to flow through the vibration enhancing apparatus;
- and
- at least one spring having a spring constant that is responsive to a vibratory tool and other tools used in a bottom hole assembly with the vibration enhancing apparatus to enhance and increase the vibration induced on the bottom hole assembly by the vibratory tool wherein the vibration induced on the bottom hole assembly by the vibration enhancing apparatus is greater than the vibration induced on the bottom hole assembly by the vibratory tool alone, the at least one spring causing the vibration enhancing apparatus to have a resonant frequency that is substantially equal to a vibrational frequency at which the vibratory tool operates.
