Systems of collection and preparation of well products

Abstract

The article is devoted to the analysis of well production collection and preparation systems. The main characteristic features of various systems are given. A typical collection and preparation system is considered. The basic equipment involved in such systems is characterized. The oil collection and preparation system includes a complex of industrial technical means and installations. The following industrial collection systems are used: - gravity two-pipe collection system - well production is divided at a pressure of 0.6 MPa. The released gas is transported under its own pressure to the compressor station or to the gas refinery. The liquid is sent to the second stage of separation. Oil and water by gravity (due to the difference in height) enter the tanks of the collection point, from where it is pumped into the tanks of the central collection point (CCP). - high-pressure single-pipe collection system - this system allows you to transfer the oil separation process to the CPS. The maximum concentration of technological equipment is achieved, the metal capacity of the oil and gas collection network is reduced, the need for the construction of pumping and compressor stations in the field is eliminated, and the possibility of utilizing associated oil gas is ensured from the very beginning of field development. - pressure collection system - in this system, single-pipe transport of oil and gas to district separation units located at a distance of up to 7 km from the wells, and transport of gas- saturated oils in a single-phase state to the CPS at a distance of 100 km or more takes place. Usually, deposits use a pressure system for collecting and preparing well products, which almost completely eliminates hydrocarbon losses
