In the process of oil and gas drilling, water-based mud is generally used in shallow Wells, and oil-based mud is used in deep Wells. Conventional solid control equipment can effectively recover heavy stones and useful drilling fluid items. Suppose these solid phase parts containing heavy metals and compounds (about 12% to 18% oil content) are discharged without treatment. In that case, long-term precipitation will cause great harm to the natural environment such as vegetation, soil, groundwater, and human living environment.
With the continuous improvement of environmental protection requirements, higher requirements have been put forward for drilling site cuttings treatment. The emergence of a drilling waste treatment and purification system can not only solve the site’s environmental problems but also carry out secondary recycling and treatment of the waste generated by the on-site solid control system. While retaining useful mud to the maximum, the drilling cuttings after reprocessing are centrally solidified. Reduce the damage to the surrounding environment.
To effectively dispose of oil-based mud drilling waste, it is necessary to use professional oil-based mud non-landing equipment and systems. The equipment used to deal with oil-based mud is: a screw conveyor + drilling cuttings dryer + environmental protection centrifuge, through this equipment, can effectively dispose of the well site waste mud, and the treated drilling cuttings can also be reused.
