Abstract

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 electroosmotic 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. A graphic-analytical method for selecting the power of an energy source is proposed. The article shows that electroosmosis can be the optimal physical process for dewatering drill cuttings. To reduce the time of the process of reclamation of sludge pits, it is advisable to eliminate the relaxation of various force gradient fields by changing the parameters of the electricity supplied to the electrodes. Recommendations are given that the technological cycle of reclamation should be carried out in one summer season, during which, using electroosmosis, reduce the moisture content of the sludge and the concentration of chemical pollutants to an acceptable level, and then sow the barn with plants and thereby return the area to normal use.
