Abstract

The invention discloses a processing device for deep-well polysulfonate drilling fluid waste mud and rock debris. The processing device is composed of a feeding machine, a cooling and heat-transferring drying furnace, a secondary combustion chamber, a three-stage cyclone separator, a barite collecting tank, a bag-type dust remover, a desulfurization tower, a water-film dust remover, a fuel-gas storage tank, a combustion chamber, an air-supplying draught fan, a hot-air nozzle, a heat-exchanging device body, an anti-bonding device body, a high-temperature pyrolyzing furnace, a collecting tank, a drying-material feeding device body, a collecting bin, a gas distributer and a feeding device body which are connected together. According to the processing device for the deep-well polysulfonate drilling fluid waste mud and rock debris, resourceful and harmless treatment of the deep-well polysulfonate drilling fluid waste mud and rock debris can be rapidly, efficiently and conveniently achieved, and meanwhile recycling of heat energy and barite resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of waste mud treatment in oil and gas fields, and in particular relates to a recycling and harmless treatment method for waste mud and cuttings of deep well sulfonated drilling fluid. Background technique [0002] In the process of deep well drilling, due to the high formation temperature, in order to achieve high efficiency and safety of drilling operations, polysulfonated anti-slump high-temperature drilling fluids with additives such as barite, sulfonated phenolic resin, sulfonated tannin, and asphalt powder are generally used Tie. This system ensures safe and rapid drilling during the drilling process. However, due to the many types of additives, high dosage and complex composition, the waste mud cuttings formed after the operation is abnormally stable, with complex pollution components and difficult treatment. It is difficult to achieve the chroma and COD of solid waste leachate by conventional solidif...
