The rationale for optimal performance characteristics of oil gathering equipment is one of the key parts of the successful organization of industrial oil production. For transfer of water-oil emulsions with high viscosity, large pressures are required, which, in turn, are limited by the strength characteristics of the pipeline. The article presents a cumulative analysis of the effect of water cut of production and residual free gas content in the flow on the pressure at the beginning of the pipeline with the current need for pumping constant volume of oil. The operation mode of the oil and gas pipeline predetermines the operation parameters of two types of equipment for the gathering and treatment system - a gas separator and a sediment tank for oil and water. They should work in a way that gas and water content in oil and gas pipeline does not exceed certain values. The residual gas content after separation is calculated by the method of D.L. Katz, which is based on the method of material balance. The calculation of the water content at the outlet from the sediment tanks is based on the sedimentation time of the water globules in the liquid flow. Based on the results of the calculations, the maximum permissible values of the residual gas and water content after the separators of the preliminary water discharge system have been established.
