Abstract

The invention belongs to the field of oil production wastewater treatment of oil fields and particularly relates to an integrated intelligent oil production wastewater treatment device and method for the oil fields. Separation, filtration, scale removal, corrosion inhibition and sterilization functions of the integrated wastewater treatment device are realized with a fuzzy control algorithm; the device comprises a water supply unit, a gas supply unit, a separation unit, a filtration unit, a scale removal and sterilization unit, an online monitoring unit and an intelligent control unit; the device has the advantages of convenience in transportation and mounting, dosing is not required during running, particularly, the stable treatment effect is guaranteed with the adoption of the intelligent control manner, the investment of chemical agents is omitted, pollution to the environment and water bodies is avoided, flexible treatment requirements can be met, the automation degree is high, and the treatment technology adopts a practical and purely physical manner.

Description

technical field [0001] The invention belongs to the field of oil field oil production sewage treatment, and in particular relates to an integrated intelligent oil field oil production sewage treatment device and method. Background technique [0002] Many oilfields in my country have entered the middle and late stages of development, and the water content in the produced fluid is 60% to 80%, and some are even as high as 90%. For this part of wastewater, most oilfields adopt the method of re-injection into the formation after treatment for recycling. At this time, it is necessary to strictly control multiple indicators such as oil content and suspended solids in the water to prevent it from causing damage to the formation. [0003] At present, for the treatment of oil production wastewater containing oil and suspended solids in oil fields, chemical dosing methods such as chemical dosing, air flotation, coagulation sedimentation, scale inhibitors, and fungicides are often used....
