【 摘 要 】

Considering the processes of oil treatment, transportation and refining of very high-viscosity index (VHVI) oil as a single technological process, the article proposes a variant of optimal technology for recovery and treatment of VHVI oil with minimizing energy and operating costs along the whole process chain, obtaining additional products, and the reduction of ecological risks. In connection with this, it is proposed to build a single ecologically safety pay zone, inside of which there are production wellheads of directional wells and all technological facilities for the production and treatment of VHVI oil, including a modular heat power plant for thermal-steam formation treatment and power generation. In addition, it is proposed to divide production fluid into asphaltum containing 95-97% of metals and "synthetic" oil, which will exclude major pipeline transport of VHVI oil, allocate the production of bitumen and metals in a separate production and reduce negative impact on the environment along the whole process chain.
