Description
Technical Field
The invention relates to the technical field of waste treatment, in particular to a device and a method for collecting, separating and harmlessly treating oil-based drilling cuttings.
Background
With the development of the technology of oil field exploitation, efficient drilling gradually replaces other exploitation modes, but another novel problem is introduced, namely that a drill bit with high impact force is often used for taking out waste drill cuttings of oil field soil layers in a well or on the drill bit in the exploitation process. In the early nineties of the last century, people often poured the grass rate of drill cuttings into the ground or seawater for treatment, but with the development of related researches, people find that the drill cuttings contain a large amount of chemical pollutants such as heavy metals, petroleum hydrocarbons and organic matters, and also breed a plurality of lethal germs such as bacillus anthracis. Thus, in the above sense, the environmental impact of drill cuttings and the potential threat to human health are reevaluated by the individual, and eventually drill cuttings are also incorporated by the country into the national hazardous waste list. The traditional flooding treatment method can cause the soil to be polluted by both chemical and microorganism, so that plants can not grow and even can permeate soil layers to pollute underground water; dumping into the ocean causes heavy metal range pollution and eventually enters the human body along with the food chain. Conventional treatments are no longer suitable and for this reason, treatment devices for drill cuttings have been devised.
The traditional drilling cutting processing device adopts a 'pyrolysis process', namely petroleum hydrocarbon substances in the drilling cutting are volatilized to oil gas at high temperature, the oil content and the heavy metal content in the drilling cutting are reduced, the oil gas enters a condenser for fraction processing, and the drilling cutting is finally decomposed into oil, water, non-condensable gas and waste residues to be discharged. The conventional pyrolysis process drill cuttings treatment device has certain limitations: when the drill cuttings are poured into the treatment equipment, the drill cuttings are in a stacking state, so that the high temperature required by the drill cuttings in the drill cuttings pile can be blocked by the external drill cuttings, the heat treatment of the internal drill cuttings is incomplete, and harmful substances are not completely decomposed; moreover, the conventional drill cutting treatment device does not have a treatment method for lethal germs such as bacillus anthracis and the like in the drill cutting, and although part of germs can be treated by high temperature generated by pyrolysis, a large number of high-temperature-resistant germs can survive for more than twenty minutes in the drill cutting, so that the harmless treatment is incomplete.

Finally, the drilling cuttings after being treated by the device are conveyed to a pyrolysis position for waste utilization through non-condensable gas, water and oil can be recycled from the outside, the remaining drilling cuttings waste residues are comprehensively combusted with petroleum hydrocarbon substances and subjected to ultraviolet degradation microbial treatment, and under the condition that the structure is simple to use and economic requirements are met, the full utilization of resources and the harmless treatment of the drilling cuttings are finally achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
