Claims (2)

1. Способ разработки месторождений высоковязких и тяжелых нефтей, включающий последовательную закачку расчетного количества теплоносителя и термостабильного поверхностно-активного вещества в скважину, выдержку скважины определенное время в закрытом состоянии, отличающийся тем, что перед закачкой поверхностно-активного вещества в пласт, призабойную зону скважины дополнительно прогревают теплоносителем, затем порционно закачивают 0,5-0,7 мас.% водного раствора поверхностно-активного вещества, при этом объем закачки определяется по формуле1. A method of developing highly viscous and heavy oil fields, including sequentially injecting the calculated amount of heat carrier and thermostable surfactant into the well, holding the well for a certain time in the closed state, characterized in that before the surfactant is pumped into the formation, the well bottom zone heated with a coolant, then 0.5-0.7 wt.% aqueous solution of a surfactant is injected portionwise, while the injection volume is determined by the forms ole Vзак=0,1*V пор=0,1*m*πh3, м3,V Zak = 0.1 * V pore = 0.1 * m * πh 3 , m 3 , где m - пористость пласта, %;where m is the porosity of the reservoir,%; h - толщина работающей части пласта, м,h is the thickness of the working part of the reservoir, m, причем оторочку поверхностно-активного вещества продавливают в пласт теплоносителем.moreover, the surfactant rim is pressed into the formation with a coolant. 2. Способ по п.1, отличающийся тем, что в качестве теплоносителя используют пар, а в качестве поверхностно-активного вещества моющие вещества "МС-1" или "MB-1″.2. The method according to claim 1, characterized in that steam is used as the heat carrier, and the detergents “MS-1” or “MB-1 ″ are used as the surfactant.
