Prospects for drilling processing technology of oil-based rock cuttings on offshore drilling platforms
A large amount of oil-based rock cuttings produced by offshore drilling platforms are usually transported by tugboats to land and handed over to enterprises with hazardous waste treatment qualification for standard treatment.During the transfer process,not only will there be a risk of leakage,but it will also consume a large amount of human,material and financial resources,and will affect the normal production of offshore drilling platforms if not transferred in time.Therefore,there is an urgent need to develop a process and e-quipment that can perform standard treatment of oil-based rock cuttings while drilling on offshore drilling platforms.After the treated residue meets the requirements,it can be directly discharged into the sea and the mineral oil in the oil-based rock cuttings can be recov-ered to prepare oil-based mud,achieving resource utilization.From the aspects of process principle,process flow,influencing factors,treatment effect and equipment operation parameters,combined with the objective conditions of offshore platforms,the feasibility of the promotion of chemical hot washing,solvent extraction,thermal desorption and low-temperature catalytic distillation technologies on off-shore platforms was discussed,providing technical reference for the standard treatment of oil-based rock cuttings while drilling on off-shore platforms.
