| Zusammenfassung: | A downhole tool assembly is configured for repeated and selective hydraulic activation and deactivation. A spring member biases the indexing control section 210 towards a first axial position while drilling fluid pressure in the tool body urges the indexing control section 210 towards other axial positions. Downhole tool activation and deactivation may repeatedly be controlled from the surface by cycling the drilling fluid pressure. |
