Embodiment Construction

[0036] Scale: 5 tons Time: July 2012

[0037] Processing method: remote processing

[0038] Process and results:

[0039] At least 2 tons of oily cuttings are processed per hour, the initial oil content is about 20-30%, and the water content in the soil is about 5%. After microwave heating, water vapor evaporates and dehumidifies, leaving 5% oil after heating. Use microwave equipment to heat oil-containing materials to about 150 degrees. The electromagnetic microwave equipment is used for no more than 12 hours a day, with a rest period in between. The total length of the equipment does not exceed 11 meters, and the width does not exceed 3 meters. The whole machine needs explosion-proof configuration. And ask for rainproof configuration.

[0040] Microwave heating and drying. Before drying, the oil content of the total material is about 30%. After drying, the deoiling rate has reached 95%. The final oil content of the final material is less than 5% after your test. The co...

Abstract

The invention relates to a treatment system and a method for drilling fluid waste, in particular to an electromagnetic treatment system and a method for oil base drilling fluid waste. Comprehensive thermal effect of light wave, electromagnetic wave and microwave is utilized for demulsification separation of water-oil emulsion in oily sludge, drying, dewatering and vaporization of waste oil, and resource utilization of oil, water and residue can be realized. Oil contents in drilling cuttings and waste are decreased under two percent, and the national standards are reached. The pollution problem of oil base drilling fluid waste is elegantly resolved on the one hand, and the waste of oil base drilling fluid or synthetic base is reduced on the other.

Description

technical field [0001] The invention relates to a drilling fluid waste treatment system and method, in particular to an electromagnetic and microwave treatment system and method for oil-based drilling fluid waste. Background technique [0002] During the drilling construction process, a large amount of cuttings and wastes are produced. Since these cuttings and wastes are polluted by drilling fluid and formation fluid, the oil content in cuttings and wastes is relatively high, which can exceed 30%. The drilling cuttings and waste produced by a well can reach hundreds of cubic meters. Plants will not grow and organisms will die, which will eventually affect our human existence. Therefore, the harmless treatment of oil-based mud drilling cuttings and waste is the need of environmental protection and the need of our human existence. Arbitrary discharge will pollute the surrounding environment, cause irreversible damage to the earth we depend on for survival, and gradually reduc...
