The experimental technique that a kind of thin heavy oil foam oil auxiliary methane is handled up

A kind of thin heavy oil foam oil auxiliary experimental technique of handling up of methane, comprises the following steps that the quartz sand layer in described back-up sand chamber injects that in-place oil, viscous crude step-down cold adopt the stage, handle up injection stage, stewing well stage, production phase and many rounds of foam oil auxiliary methane is handled up the stage.It in the injection stage, is initially injected the oil soluble surfactant solution that can form foam oil, injects methane gas afterwards, increase strata pressure, enlarged surface activator solution and crude oil contact area.Many rounds are handled up the stage, change injection phase according to remaining oil distribution, expand the contact area injecting surfactant and methane and crude oil.The present invention overcomes conventional methane production phase strata pressure of handling up to reduce rapidly, deficiency and thermal methods that viscosity of crude raises again develop the problem that thin heavy oil heat loss is serious, cost of investment is high, have bigger application prospect for thin heavy oil exploitation.
