| Abstract. | Now about 90 % of oil are extracted on the fields developed with use of methods of water flooding of oil layers for keeping up of bench pressure. Purification of the oil-field sewage (OFS) for water flooding of the productive horizons consists at a distance from them to the set norms of oil and mechanical impurity. The essence and success of process of cleaning of OFS consists in destruction of the adsorptive reserving cover on drops of the disperse phase (oil), previous merge, their integration. Thus defining depth and speed of process of cleaning of OFS extent of destruction of the specified cover on oil drops, the mode of movement OFS providing integration of these drops is. These processes are carried out most fully and intensively at certain extent of turbulization of a stream of OFS in a cavity of various hydrodynamic dropformers with the subsequent decantation. Release of a trial complex of a hydrodynamic dropformers of the «hydrocyclone – chamber drains» (HCD-75) type is mastered and carried out; introduction of trial «set hydrocyclone – chamber drains – setting tank» (BGKO) installation for OFS cleaning for the purpose of water flooding of oil layers in the conditions of OAO «Tatneft» is carried out. Advantages of this device are high reliability, high effect of cleaning and high specific efficiency; the complex hydrodynamic processing of OFS combined with intensive contact cleaning; uniform collecting the cleared water and deposit; hydrodynamic destruction of an intermediate layer and exception of formation of this layer, rather full and fast removal of a deposit; possibility of carrying out repair and preventive and emergency works without device termination of work; block of full factory production.Improvement of quality of water pumped in layer brings: to involvement in development of layers of low permeability and to increase in oil production; to increase in the between-repairs periods of a well, therefore, additional oil production; to reduction of number of again being drilled wells, in connection with loss of acceleration performance drilled earlier; to decrease in environmental pollution. OFS use in systems of flooding of oil layers is only economically and ecologically favorable way of their elimination on crafts. |
