The invention discloses an oil-based rock debris resource recycling system which comprises a drilling mud storage unit, a coarse treatment unit, a thermal desorption unit, a fine treatment unit, a wastewater treatment unit, a waste gas treatment unit, a waste residue collection unit and an integrated control unit. The coarse treatment unit comprises a solid-liquid separation unit and a dilution unit; The thermal desorption unit adopts a non-contact heater, a spiral conveying shaft is arranged in the non-contact heater, a waste residue outlet and a steam outlet are formed in the non-contact heater, one end of the steam outlet is connected with the waste gas treatment unit through a condensing device, and one end of the condensing device is connected with the wastewater treatment unit. The waste drilling fluid is directly treated in a thermal desorption mode, secondary pollution is avoided in the treatment process, complete recycling of resources is achieved, the zero-emission effect is achieved, and environmental pollution is reduced; harmless treatment of the oil-based mud is realized, the oil-based mud can be directly spread on a well site roadbed or a building raw material after being cured, and the system has a relatively high practical application value.
Description
technical field [0001] The invention relates to the technical field of oil-based cuttings, in particular to a recycling system for oil-based cuttings resources. Background technique [0002] Drilling cuttings are rock particles that are ground or broken by the drill bit during oil and gas drilling. It is brought out of the well to the surface by the drilling fluid. Because drilling fluids, especially oil-based drilling fluids, contain a large amount of oil, such as diesel oil, crude oil, coal tar, vegetable oil, animal oil, synthetic oil, and mineral oil, oil substances are the main components of oil-based drilling fluids, and their concentration is generally Between 50%-100%. Drilling waste mixed with oil-based drilling fluid and drilling cuttings will be separated and treated to obtain oily drilling cuttings, which will cause multiple impacts and hazards to the surrounding environment if not properly treated. [0003] The oily drilling cuttings discarded around the well...
