New concepts concerning solid control technology in oil drilling engineering

The solid control system is the key equipment in oil drilling engineering, which exerts direct effect on the drilling speed,the hole quality and the cost. With the development of the drilling technology, higher level solid control is demanded. This paper analyzesthe current state and the defects of the solid control system now used. The key points to improve the solid control system are pointedout, including simplification and optimization of the system, sieving process after degassing, full processing of the mud, selective solidcontrol, dewatering of drill cuttings, and recovery of the drilling fluid. High process efficiency, low energy consume, little pollution andhigh drilling speed can be expected when these new solid control technologies are used.
