Механизм процесса вытеснения нефти

Механизм процесса вытеснения нефти из пластов водным малоконцентрированным раствором поверхностно-активных веществ (ПАВ) основан на том, что при этом снижается поверхностное натяжение между нефтью и водой и увеличивается краевой угол смачивания. Следовательно, натяжение смачивания уменьшается в 8-10 раз.
Процесс разработки нефтяных месторождений при заводнении их водными растворами ПАВ осуществляется с минимальными изменениями в технологии и системе размещения скважин.
Добавление к закачиваемой воде 0,05-0,1 % ПАВ не влечет за собой необходимости существенного изменения давления, темпов или объемов нагнетания воды. Объемы закачиваемых в пласты водных растворов ПАВ

Process mechanism of oil displacement by water from the seams malokoncentrirovannym solution of surfactants based on the fact that this reduces surface tension between oil and water and wetting angle increases. Consequently, tension wetting decreases in 8-10 times.The process of developing oilfields in flooding their aqueous solutions of SURFACTANTS is done with minimal changes in technology and system properties.Adding to the injected water -0.1 0.05% SURFACTANT does not entail the need for substantial changes in pressure, rate or volume of water injection. The volume pumped into formations of aqueous solutions of SURFACTANTS

The mechanism displacing oil from reservoirs of low-concentration aqueous solution of surface-active substances (surfactants) process is based on the fact that it reduces the surface tension between oil and water and the contact angle increases. Consequently, the wetting tension is reduced by 8-10 times.
The process of development of oil fields by flooding them with aqueous solutions of the surfactant is carried out with a minimum of changes in technology and the system of wells accommodation.
Adding to 0.05-0.1% surfactant injected water does not entail the need substantial changes in pressure, rate or volume of water injection. The volume of water injected into the formation of surfactant solutions

the process of displacement of oil by water малоконцентрированным solution of surfactants (surfactant) is based on the assumption that it decreases the surface tension between oil and water and the growing edge angle of wetting. consequently, the wetting is reduced to 8 to 10 times.the process of the development of oil fields in the заводнении of their water solutions of surfactants is implemented with minimal changes in the technology and system of wells.addendum to the закачиваемой water 0.05 - 0.1% surfactant does not entail the need for significant changes in pressure, or volume of circulating water. the volume закачиваемых in aqueous surfactant layers
