Description
Technical Field
The invention belongs to the technical field of dangerous waste treatment, relates to a technical method for cooperatively treating dangerous waste by a cement kiln, and particularly relates to system equipment for cooperatively treating drilling oil-based mud cuttings by the cement kiln.
Background
The drilling oil-based rock debris is a solid waste generated in the oil-gas resource drilling process, and the direct discharge of the drilling oil-based rock debris can seriously pollute the environment due to the fact that the drilling oil-based rock debris contains a large amount of oil substances, and is dangerous waste specified in the national plaintext. Innocent treatment of drilling oil-based mud cuttings becomes a pain point and a difficulty in the green exploitation process of oil and gas resources.
The currently adopted treatment process flow is that firstly, rock scraps in oil-based drilling fluid are separated through a vibrating screen, then, the oil-based drilling rock scraps are dehydrated and deoiled through a spin dryer and a centrifuge, and oil-based rock scraps dry powder with low oil content and waste drilling oil-based mud rock scraps with high oil content are formed. Wherein, the oil-based rock debris dry powder with low oil content is subjected to innocent treatment by high-temperature incineration.
The drilling oil-based mud cuttings with high oil content contain a large amount of high-value oil resources, but at the same time, the drilling oil-based mud cuttings contain a large amount of fine cuttings particles, so that the drilling oil-based mud cuttings have high density and poor fluidity and cannot be directly used for preparing oil-based drilling fluid for the second time. The harmless treatment can be realized by directly burning at high temperature, but the great waste of oil resources is caused. At present, the recovery of base oil can be realized by thermal desorption, extraction and other processes. The process is characterized in that the base oil is obtained through heating and distilling, and because the process needs to heat the slurry to more than 400 ℃, partial base oil is thermally cracked to generate volatile organic gas with harmful and peculiar smell, the recovered base oil cannot be reused for preparing drilling oil-based slurry cuttings, and the reuse in other fields cannot be realized; the extraction process is to add extractant to realize solid, oil and water three-phase separation, and the recovered base oil can be recycled, but has the problems of high cost and small treatment capacity.
