Abstract
A tool for use in a wellbore comprising a seal assembly and a cone member configured to force the seal assembly radially outward into engagement with the wellbore. A shear thickening fluid is disposed within an area formed between the seal assembly and the cone member. The shear thickening fluid is configured to prevent relative movement between the cone member and the seal assembly when the shear thickening fluid is changed from a substantially fluid state to a substantially solid state due to a sudden force applied to the shear thickening fluid, by release of a sheared mechanism for example.
Claims19
A tool for use in a wellbore, comprising:
- a seal assembly;
- a frustoconical member configured to force the seal assembly radially outward into engagement with the wellbore;
- and
- a shear thickening fluid disposed within a volume bounded by the seal assembly and the frustoconical member such that the shear thickening fluid directly contacts the seal assembly and the frustoconical member.
A method of controlling a tool in a wellbore, comprising:
- transmitting a force from a frustoconical member to a seal assembly, wherein a shear thickening fluid is disposed within a volume bounded by the frustoconical member and the seal assembly such that the shear thickening fluid directly contacts the frustoconical member and the seal assembly;
- changing the shear thickening fluid from a substantially fluid state to a substantially solid state;
- and
- preventing relative movement between the frustoconical member and the seal assembly by changing the shear thickening fluid from the substantially fluid state to the substantially solid state.
