Engineering Application of Circulation Material with Polyacrylamide and Cutting Grease

Abstract:

Traditional clay ball, cement ball, rapid hardening cement and lost circulation additive with sawdust were ineffective for drilling construction in a mine of shanxi, while polyacrylamide and cutting grease brought high efficiency with good sealing effect and low cost, which could reduce the drilling tool wearing, precipitate the drilling waste and purify the washing fluid. The paper briefly introduced the sealing method and the application result.
