  • Oil-bearing waste drill solids bring about serious pollution to the environment around the well site. Oils on drilled solids are generally removed with specially designed oil removers which have limited versatility. Based on the pollution characteristics of oil-bearing drilled cuttings and oil-bearing sludge, a new high performance broad-spectrum oil remover has been developed through molecular structure design. The new oil remover is capable of disposing of both oil-bearing drill cuttings and oil-bearing sludge. The structure of the new oil remover has been characterized with IR spectrum and mass spectrum etc. Surface tension and wettability measurement indicated that the new oil remover is highly surface active. The optimum conditions for oil-bearing drill cuttings disposal are:oil remover concentration at 1 000 mg/L, temperature at 50℃, centrifugal speed at 4 000 r/min, and centrifugal rotation time for 10 min. The optimum conditions for oil-bearing sludge disposal are:oil remover concentration at 2 000 mg/L, temperature at 50℃, centrifugal speed at 4 000 r/min, centrifugal rotation time for 10 min. Oil removing test showed that 90% of oils contained on drill cuttings or sludgecan be removed with the new oil remover, realizing oil removing with one broad-spectrum oil remover.
