The invention discloses an oilfield solid waste treatment medicament. The oilfield solid waste treatment medicament is characterized by comprising the following components of, a pour point depressant,a pH regulator, a dispersing agent, a viscosity reducer, a cleaning agent A, a cleaning agent B, a dehydrating agent, a photocatalyst, a zeolite molecular sieve, activated carbon, a ceramic ring, ananti-adhesive agent and a desulfurizing agent. The oilfield solid waste treatment method comprises the following steps of performing thermal chemical washing operation and dry distillation carbonization operation, according to the characteristics of oilfield solid waste generated by different stratums or working conditions, the thermal chemical washing operation or the dry distillation carbonization operation is independently adopted, or the thermal chemical washing operation is carried out firstly, and then the carbonization operation is carried out. The oilfield solid waste recycling treatment process is simple and feasible, and the application range is wide; the treated solid phase, oil, water and gas can be recycled, and the standard solid phase is used as a civil engineering raw material; the oil phase is recycled to an oilfield or used as an industrial oil raw material; the water phase is recycled to a cooling device or can be used in the thermochemical cleaning operation; and the non-condensable gas enters a combustion chamber of a dry distillation furnace for combustion and heat supply, so that the environment-friendly requirement is met.
