Abstract

The invention discloses a glucose high-efficiency oil-displacing agent and an oil displacement method. The oil-displacing agent is driven into an oil-displacing zone. The oil-displacing agent is prepared from the following raw materials (by weight): 30-60 parts of sodium polyalkylbenzene sulfonate, 15-30 parts of glucoside, 20-30 parts of straight-chain fatty acid alkanolamide sulfate salt, 5-15 parts of alkali, 5-10 parts of glyoxal, 10-30 parts of alkyl glycoside, 10-15 parts of Tetrakisphosphonium sulfate, 5-10 parts of a chelating agent, 5-10 parts of nano-silica sol and 5-10 parts of lauramidopropyl betaine. The invention has the beneficial effect as follows: the oil-displacing agent of the invention can improve the oil yield of tertiary recovery, has stability, and can ensure oil displacement of the entire oil zone.

Description

technical field [0001] The invention relates to the technical field of oil collection, in particular to a glucose high-efficiency oil displacement agent and an oil displacement method. Background technique [0002] At present, it is very difficult to recover refined oil in Liaohe Oilfield. Secondary oil recovery recovers about 20% of the crude oil in the ground. Carry out tertiary oil recovery, that is, chemical flooding. The existing oil displacement agents usually only pursue ultra-low interfacial tension, and the oil displacement properties are not good. Contents of the invention [0003] The object of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of high-efficiency glucose oil displacement agent and oil displacement method. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A glucose high-efficiency oil-displacing agent and an oil-displacing method...
