The invention relates to a novel inorganic fine particle enhanced foam system for oil and gas fields, and a preparation method thereof. The enhanced foam system comprises a gas phase and a liquid phase; the gas phase is nitrogen, carbon dioxide or air; the liquid phase comprises 0.2-0.8wt% of a foaming agent, 0.5-2.0wt% of novel inorganic fine particles, and the balance of water; and the novel inorganic fine particles are fine particles with the particle size being not greater than 2.5[mu]m, trapped and screened from air. The invention also provides the preparation method of the foam system. The enhanced foam system can be used to benefit efficient exploitation of oil and gas resources, can change the novel inorganic fine particles into valuables, reduces pollution of the novel inorganic fine particles to air environment, and has the advantages of low cost of the raw materials, simple preparation process, low operation cost, good oil and gas yield increasing effect, and high economic benefit.

The medicament comprises the following components in parts by weight: 13-15 parts of 40% imazalil emulsion in water, 10-14 parts of 25% Tanteling powder, 14-16 parts of herba centellae extract, 2-4 parts of astragalus polysaccharides, 2-4 parts of cinnamyl aldehyde, 3-8 parts of diethyl aminoethyl hexanoate, 10-14 parts of wintergreen barberry root extract, 10-14 parts of isopropyl alcohol, 6-8 parts of kudzuvine root extract and 50-60 parts of water. Meanwhile, the application method of the medicament is simple and convenient. The medicament has good control effects, is simple in preparation process and convenient to use, reduces the pesticide dosage and environmental pollution, and is beneficial to ecological balance.

The invention discloses a preparation for preventing and controlling Magnolia figo leaf blight and a use method of the preparation. The preparation comprises the following components in parts by weight: 31-40 parts of Bismerthiazol, 15-20 parts of Bordeaux mixture, 10-15 parts of wintergreen barberry root extract, 8-14 parts of red-knees herb extract, 10-40 parts of rhizoma acori graminei extract, 5-8 parts of alkyl naphthalene sulfonate, 5-10 parts of polyvinyl alcohol, 5-10 parts of zingerone, 10-15 parts of magnesium sulfate, 4-7 parts of citric acid and 70-80 parts of water. The use method of the preparation is simple and convenient. The preparation has the beneficial effects that the prevention effect is good, a preparation process is simple, the use is convenient, the use amount of a pesticide is reduced, the environmental pollution is alleviated, and the ecological balance is benefited.

The invention discloses a gas-solid composite ultra-fine powder-based extinguishing agent and a preparation method thereof, which are characterized in that according to the mass percentage in the system, 73-89 percent of ultra-fine zeolite, with the average particle size below 10 microns is arranged in a pressure withstanding vessel for vacuum-pumping; subsequently, 5.0-20.0 percent of 2-bromine-3, 3, 3-trifluoropropene liquid is injected into the vessel, stands for 12-24 hours at the temperature of 35-50 DEG C and cooled to room temperature; subsequently, 0.5-2.0 percent of barium hydroxide and 2.5-5.0 percent of talcum powder are added into the vessel and all powders are uniformly mixed; the obtained gas-solid composite ultra-fine powder-based distinguishing agent has high distinguishing efficiency, low corrosion and good anti-afterburning; the raw material is cheap and easy to be obtained; the preparation process is simple; the gas-solid composite ultra-fine powder-based distinguishing agent not only can be used as a distinguishing agent but also can be used as an additive to various commercial powder extinguishing agents, and is applicable to various fire extinguishers for fighting various fires such as solid fire, combustible gas fire, liquid fire and the like.
