Application of electrosmos in the oil field

The problem of reclamation of sludge pits in oil fields is still being solved using the resource-intensive method. An accelerated technology of sludge dewatering by electro-osmotic action is proposed. The concept of specific energy consumption for mass transfer is introduced. To eliminate the influence of relaxation of gradient fields, it is proposed to change the parameters of electrical energy. It has been established that electroosmosis can be the optimal physical process for sludge dewatering. To reduce the time of the process of reclamation of sludge pits, it is advisable to remove the relaxation of various force gradient fields by changing the parameters of the electricity supplied to the electrodes. The technological cycle of reclamation, carried out in one summer season, is substantiated, during which, with the help of electroosmosis, the moisture content of the sludge and the concentration of chemical contaminants are reduced to an acceptable level.
