Reducing capital investments to expand on-site oil, gas and water treatment facilities is one of the priorities for oil and gas producing companies. This publication analyzes the performance indicators of several typical on-site oil, gas and water treatment facilities. Using a standard approach to solving the problems of increasing loads, destruction of stable water-oil emulsions and preparation of produced water, the fleet of capacitive technological equipment of the facility is being expanded. This approach is associated with a number of significant time and financial costs and does not allow organizing a solution to the problem in a short time. Based on the conducted research, the most overloaded technological block of the studied oil and water field treatment facilities is the tank block of vertical steel water treatment facilities. The scientific and technical approach proposed by the authors is not innovative for Russian oil companies; however, it allows increasing the efficiency of water treatment tanks when performing a list of certain engineering works. Field studies assessed the density of distribution and dispersion of particles of petroleum products and mechanical impurities in samples of produced water. It has been established that residual oil products are mainly represented by particles with a dispersity of less than 50 microns. Criteria for the use of new internal components of water treatment plant tanks have been determined, such as: maximum use of tank volume by distributing water flows and eliminating stagnant zones; ensuring maximum efficiency of internal components; minimizing the risk of sedimentation of suspended particles in water inlet and outlet pipelines. The technical and technological solutions under consideration make it possible to optimize the introduction of liquid and its distribution throughout the water treatment tank, to form an additional surface to intensify the physical and chemical processes of sedimentation and coalescence of particles.
