The invention discloses a nano imbibition oil displacement agent as well as a preparation method and application thereof. The preparation method of the nano imbibition oil-displacing agent comprises the following steps: reacting citric acid, glucose, long-chain amine, a surfactant, an organic solvent, short-chain alcohol and water at 140-200 DEG C under 0.4-0.5 MPa for 6-16 hours to obtain the nano imbibition oil-displacing agent. The method disclosed by the invention is simple, convenient, environment-friendly and low in cost, and the prepared nano imbibition oil displacement agent has good surface and interface activity at high temperature and high salt, can be used as an imbibition oil recovery agent for an ultra-low permeability reservoir, and can remarkably improve the oil recovery rate.

The invention belongs to the technical field of veterinary preparations, and particularly relates to a tilmicosin premix and a preparation method thereof. The tilmicosin premix is prepared from the following raw materials: tilmicosin, a polylactic acid-glycolic acid copolymer, lecithin, modified hydroxypropyl methyl cellulose, grafted polyvinylpyrrolidone, polyethylene glycol and an antioxidant, a solid dispersion is formed through lecithin and grafted polyvinylpyrrolidone, the solubility and stability of tilmicosin are enhanced, polylactic acid-glycolic acid copolymer nano-microspheres are prepared through a double-emulsion solvent evaporation method, slow release of drugs is achieved, dodecyl modified hydroxypropyl methyl cellulose and polyethylene glycol are combined, and the sustained release effect is achieved. The solubility and the slow release characteristic are further enhanced. The activity of the granular premix is effectively preserved, and the granular premix is convenient to use and transport.

The invention discloses an aero-engine runner cleaning agent and a use method thereof. The aero-engine runner cleaning agent is prepared from the following raw material components in parts by weight: 65-80 parts of water, 7-9 parts of sodium metasilicate, 5-8 parts of a composite surfactant, 1-3 parts of triethanolamine oleate and 7-15 parts of saturated isoparaffin. The using method of the cleaning agent comprises the steps that the engine is not detached from an airplane, in the cold running or slow running state of the engine, the cleaning agent is atomized into water particles of 50-100 micrometers through an injection method, the water particles are injected into an air flow channel through an engine cleaning nozzle, and deposits such as carbon, salinization, dust dirt and oil dirt on the engine air flow channel are effectively cleaned on line. The engine runner cleaning agent has the characteristics of no damage, rapidness and no corrosion to a base material, can be used for on-line cleaning of salinization, oil dirt, dirt, carbon deposition and other sediments on the engine runner, and is less in engine cleaning agent consumption and high in cleaning efficiency compared with traditional engine runner cleaning.

The invention relates to the technical field of heavy oil thermal recovery reagents, in particular to a strong emulsion system for assisting viscosity reduction and plug removal as well as a preparation method and application thereof. The strong emulsion system is prepared from the following raw materials in percentage by mass: 2%-10% of sorbitol dehydrated ester mixture, 5%-10% of 120 # solvent oil, 3%-6% of alcohol ether carboxylate, 0.5%-1.0% of ethylene glycol tert-butyl ether, 5%-10% of organic acid, 3%-6% of polybasic polycarboxylic acid, 3%-6% of villiaumite, 1%-2% of imidazoline corrosion inhibitor, 1.0%-3.0% of functional additive and 46%-76% of water. The strong emulsion system can perform deep plug removal on an underground reservoir and prevent organic acid of the strong emulsion system from being combined with heavy components in the thick oil so as to avoid formation of acid sludge, so that the plug removal effect of the strong emulsion system can be improved.

This invention discloses an epoxide derivative, its preparation method, and its application. The epoxide derivative has the chemical structure shown in formula (I): R-O-(EO). a -(PO) b - [(EO) c -(PO) d ] n - (EO) e -(PO) f -H (I); where R represents a C4-C32 straight-chain or branched alkyl group, and the [(EO)] c -(PO) d ] n The total block unit represents n (EO)-(PO) blocks linked together, where n ranges from 2 to 16. c and d represent the average molar number of EO and PO in the total block unit, with values ​​ranging from 1 to 10 and 1 to 2.5, respectively. a, b, e, and f each represent the average molar number, with values ​​of a and e ranging from 0 to 10, and values ​​of b and f ranging from 0 to 30. The epoxy alkyl derivatives of this invention combine low-temperature flowability, water solubility, and safety, and can be used as high-performance surfactants.
