Abstract: The present invention provides an amphiphilic molecular sieve containing a lipophilic group on the outside and a hydrophilic group on the inside and a production method thereof. The production method comprises: dispersing the nano-ZSM-5 molecular sieve into toluene, adding an organosilane containing a lipophilic group and reacting at 60-100° C. for 4-16 h, to obtain a molecular sieve containing a lipophilic group; placing the molecular sieve containing a lipophilic group in a mixed solution of sodium hydroxide solution and ethanol and reacting at 60-95° C. for 20-60 min, to obtain a molecular sieve containing a lipophilic group on the outside; dispersing the molecular sieve containing a lipophilic group on the outside into toluene, adding an organosilane containing a hydrophilic group and reacting at 60-100° C. for 4-16 h, to obtain the amphiphilic molecular sieve containing a lipophilic group on the outside and a hydrophilic group on the inside. The present invention also provides a molecular sieve obtained by the above production method, which does not destroy the characteristics of the original molecular sieve and has hydrophilic and lipophilic amphiphilic properties.

CPC classification number: C09K8/584 , E21B43/16 , C09K2208/10
Abstract: A permeability-enhancing flooding system for tight oil reservoirs and preparation and use thereof are disclosed. The permeability-enhancing flooding system is present in a state of oil-in-water droplet and composed of a surfactant, an oil-soluble substance and water, and has an outer phase that is an aqueous solution containing the surfactant, and an inner phase that is the oil-soluble substance; and the surfactant comprises one of nonionic gemini surfactants and anionic gemini surfactants, or a combination of two or more thereof. The preparation process for the permeability-enhancing flooding system is simple to operate, suitable for industrialized production, and low in overall cost, and has obvious application prospects in the field of tight oil reservoirs for an enhanced oil recovery.

Abstract: The invention discloses a nonionic Gemini surfactant, (octylphenol polyoxyethylene ether disubstituted) dicarboxylic acid diphenyl ether and its synthesis method, which nonionic Gemini surfactant has a structural formula of: and is prepared by a two-step reaction: S1, diphenyl ether 4,4′-dicarboxylic acid is subjected to an acyl chlorination reaction to obtain diphenyl ether 4,4′-dicarbonyl dichloride; S2, diphenyl ether 4,4′-dicarbonyl dichloride is subjected to an esterification reaction with octylphenol polyoxyethylene ether (OP-10) to obtain the target product (octylphenol polyoxyethylene ether disubstituted) dicarboxylic acid diphenyl ether. The surfactant of the present invention is expected to be applied in tertiary oil recovery as an alkali/surfactant, in polymer/surfactant binary composite flooding, in alkali/surfactant/polymer ternary composite flooding, as a microemulsion emulsifier and the like, and it can also be compounded with a common surfactant to reduce the use cost, and thus create conditions for its large-scale application.
