【 摘 要 】

A new type of leaching solvent for oily drilling cuttings was developed, and the effect of leaching solvent on the oil removal for oily cuttings was investigated. The results indicated that the leaching solvent had good capacity of oil removal for oily cuttings, and the oil content of treated cuttings is less than 0.6%. The leaching solvent could be separated from the oil phase through distillation, and the recyclable solvent could be reused to treat other cuttings. Moreover, oil resources adsorbed on the oily cuttings could be recycled and reused to prepare new drilling fluids, so the drilling cost could be reduced greatly. As a result, the leaching solvent could treat the oily cuttings effectively, and recycle and reuse oil resources, and thus produce great economic benefits. It can play an essential role in safe drilling jobs and improvement of drilling efficiency in the future.
