| titleOfInvention | High salinity reservoir gas drive foam compositions and preparation method and purposes |
| abstract | The present invention relates to a kind of high salinity reservoir gas drive foam compositions and preparation method and purposes, the problem of foaming agent present in existing high salinity reservoir gas drive oil recovery process meets divalent ion precipitation, causes has channeling is mainly solved.The present invention is by using a kind of foam compositions, including glycine betaine foaming agent, anionic and nonionic foaming agent and gas, glycine betaine foaming agent, anionic and nonionic foaming agent and gas phase are mixed to form foam, wherein glycine betaine foaming agent is alkyl amido betaine, anionic and nonionic foaming agent is any one in alkyl polyoxy second/propylene ether carboxylate or alkyl polyoxy second/propylene ether sulfonate, gas be with foaming agent into the gas of inertia relation any one, the mol ratio of described glycine betaine foaming agent and anionic and nonionic foaming agent is 1:0.01~1:100, gas is 0.1~10 with liquid volume ratio:1 technical scheme preferably solves the problem, available in gas drive enhanced oil recovery process. |
