Abstract: With the increasing intensity of shale gas exploitation year by year,the amount of oil-based drilling cuttings needs to be dealt with is also increasing.Oil-based drilling cuttings are dangerous solid wastes,and their disposal costs account for a large proportion of drilling costs.In order to reduce the drilling cost,simplify the disposal process,and reduce the safety risks caused by oil-based drilling cuttings transport,a skid-mounted high-temperature plasma gasification and melting treatment system and device is designed.Each module of the system and the principle of operation are introduced,and the structure design and heat transfer calculation for key devices are carried out,and some experimental results of the system are checked.The calorific value of syngas produced by the system is 266,844 kJ·L-1,accounting for 81% of the calorific value of the input fuel.
