| description | The invention provides a composition for a penetration-driving oil recovery agent. The composition comprises the following components in percentage by weight: 0.5-45 percent of a main agent, 0.5-50 percent of an auxiliary agent and 5-99 percent of an inorganic alkali metal salt, wherein the main agent is polyacrylate, and comprises one or a combination of potassium polyacrylate, polyacrylate sodium, sodium polymethacrylate and ammonium polyacrylate; and the auxiliary agent is one or a combination of polyaspartic acid, polyaspartate and polyoxyethylene sorbitol anhydride mono-fatty acid ester. The invention further provides a penetration-driving oil recovery agent containing the composition for the penetration-driving oil recovery agent and a preparation method thereof and an application thereof in an oil recovery process. The penetration-driving oil recovery agent provided by the invention is prepared from simple and readily-available raw materials, has low using amount, and particularly has high recovery rat |
