Research on Solid Control System of Flushing Fluid Circulation in Geological Core Drilling and the Matching Technology

Abstract:

In view of the higher requirements on flushing fluid properties by new drilling technique, new method, new technology and new tool, such as hydro-hammer and down-hole dynamic drilling tool, the solid control system of flushing fluid circulation in the geological core drilling is developed according to the construction site situation. The whole circulation system is configured with mud cleaner and the two-stage purifying equipment centrifuge and designed with integrate module with properties of strong adaptability, convenient transportation, safety and reliability.

Key words:geological core drilling; flushing fluid; purification; solid control system
