FIELD: oil and gas production. ^ SUBSTANCE: here is disclosed procedure for production of hydrocarbons from underground reservoir, wherein there is formed emulsion stabilised with solid particles - SSE and where SSE includes oil as first fluid, drops of second fluid suspended in oil and solid particles not soluble both in oil and in second fluid under conditions of underground reservoir. SSE with dissolved gas is pumped into the underground reservoir as replacing fluid and at least part of SSE gets into one or several regions of the underground reservoir having in situ pressure sufficiently lower, than chosen partial pressure to facilitate evaporation of at least part of gas from oil. Procedure for preparation of foam SSE consists in making SSE, in dissolving gas in said oil, in using low pressure to release at least part of said gas from said oil and to generate gas bubbles in said oil. ^ EFFECT: raised stability of emulsion and efficiency of hydrocarbons driving. ^ 37 cl |
