Abstract

The oil-fields development and operation can be associated with high water consumption and waste water emission. Most of the pollutants come from drilling and formation waters. At the same time, a significant proportion of solid dispersed pollutants is accounted for drilling waste water. Formation waters are the main source of oil contaminants. The technological processes of oil-field waste water treatment are based on gravity separation. In the context of increasing the environmental requirements for production activities, especially in the regions with low average annual temperatures and, accordingly, slow processes of ecosystems’ self-cleaning, the problem of environment reliable protection arises. Gravity separation methods cannot provide the required quality of waste water treatment. Modern achievements in the field of baromembrane technologies and high salinity of waste water make it most effective and expedient to use membrane and electrochemical methods of waste water treatment.

Highlights

  • The oil industry is characterized by significant water consumption and is the source of a large amount of waste water

  • The peculiarity of oil production enterprises is their large dispersion over the territory of the oil-bearing region

  • The indicators of the waste water main flows from oil-fields depend on the geological conditions of the oil production area, the applied technological processes and equipment

Summary

Introduction

The oil industry is characterized by significant water consumption and is the source of a large amount of waste water. Water consumption for the main technological processes can reach 5 m3 for 1ton produced oil. The peculiarity of oil production enterprises is their large dispersion over the territory of the oil-bearing region. In this regard, maintaining the normal ecological state of nature and protecting water resources in the areas of oil-fields is an important and urgent problem. The oil-fields development and reclamation can be associated with well drilling. The total amount of drilling waste water is 1000 m3 for every 1000 m well penetration
