Purpose of the development: Recycling of accompanying oil gas extracted with oil by means of its return pumping into the stratum as part of water-gas mix, environmental protection, increase of final petroextraction factor.

Recommended application field: It is expedient to organize use of AOG directly on oil-fields, for example, by means of its return pumping into oil strata as a part of water-gas mix.

Advantages over analogues: decreasing oil viscosity owing to dissolution of gas in it replacement of oil from large hydrophobic pores and the top dead end zones by gas replacement of oil by gas, as it moves to the top part of the stratum creation of favorable conditions for emulsified oil-water phases flow.

The development stage readiness: Introduced in production

Description of the development:
()
The immense emissions of accompanying oil gas (AOG) combustion products into the atmosphere air changes the atmospheric when they become air composition, bringing concentrations of toxic substances to values biologically hazardous to people, animals, plants. The increase in degree of petroextraction is achieved by way of: decreasing oil viscosity owing to dissolution of gas in it replacement of oil from large hydrophobic pores and the top dead end zones by gas replacement of oil by gas, as it moves to the top part of the stratum creation of favorable conditions for emulsified oil-water phases flow. There are two schemes of introduction of the technology of impact on the stratum of water and accompanying oil gas (WAG): non-compressor technology of WAG for creation of a water-gas mix directly in one borehole) recycling considerable volumes of gas by means of WAG impact on the block of boreholes (pumping of ready water-gas mix). 3 patents and 2 certificates of authorship have been taken out. The technology has been introduced into boreholes of enterprises “Strejevoyneft” and “Vakhneft” (JSC “Tomskneft”).
