Method for separating solid lubricating material from drill cuttings |
摘要 |
Solid lubricating particles such as spherical plastic beads which are useful in drilling operations are separated from drill cuttings by (1) depositing a mixture of the particles and cuttings on a reciprocating deck which operates in a manner such that the mixture moves in one direction across the deck and (2) passing a wash stream across the mixture in a second direction approximately perpendicular to the direction of the mixture flow. The wash stream causes the solid lubricating particles to move in the second direction at a rate significantly greater than the drill cuttings. The lubricating particles are readily recovered from the drill cuttings for reuse in the drilling operation.
