Currently, the search for optimal solutions in the field of collecting and preparing well products in the fields is a very important task. The main problem in the development of the assets of extractive companies is the need to improve the systems of arrangement and development of technological schemes, aimed at optimizing capital and operating costs in the later stages of field development. One of the effective ways to increase capacity and eliminate the shortage in the preparation and transportation of well products in the fields, both at the later stages of development and at the stages of pilot development, is the installation of mobile oil treatment units (MOTU). MOTU have a modular layout, which accelerates the start of well production by reducing the time required for construction and installation work and commissioning work. An additional effect from the use of MOTU is achieved in combination with downhole preliminary water discharge units, which makes it possible to reduce the volume of water pumping and increase the energy efficiency of production and transport of high water cut oil emulsions.
The authors compared two options for collecting and treating oil in the field: 1) gathering and dehydration of the gas-liquid mixture at the well preliminary water discharge unit with oil treatment at MOTU; 2) gathering and separation of the gas-liquid mixture at the preliminary water discharge plants in a stationary version (capital construction facility). The main objective of the comparison is selecting the optimal option for primary oil treatment to ensure a sustainable production profile and maximum hydrocarbon production. The article presents the necessary conditions, features and advantages of the use of well preliminary water discharge unit. A comparison of the economic efficiency indicators of the above-described options for oil treatment at the fields is given.
