Processing method of drilling operation oil base drilling cuttings

The invention discloses a processing method of drilling operation oil base drilling cuttings, and relates to the technical field of oil and gas exploration drilling pollution abatement. The processingmethod comprises the steps that a, by weight, 5% of microorganism solid bactericide is added into shale gas drilling oil base drilling cuttings, then 200% of soil is added into and uniformly mixed with the shale gas drilling oil base drilling cuttings, and moisture content of the mixture is adjusted; b, the mixture is placed at a designated place, the mixture is cover with the soil with thicknessof 5-10cm, a microorganism-soil system is utilized to degrade conglutination oil in the mixture; c, after the degradation processing for 6-9 months until oil content in the mixture is 1% per long ton, a curing agent is added into the processed mixture to make roadbed materials of cement bricks or highways. The processing method can effectively remove the conglutination oil in the shale gas drilling oil base drilling cutti
