The invention belongs to the technical field of food attractants, and particularly relates to a dichocrocis punctiferalis food attractant. The invention relates to a food attractant. The food attractant is prepared from alpha-pinene oxide, methyl glucoside caprylate and leaf acetate according to the mass ratio of 1: (1-3): (1-5). According to the food attractant for dichocrocis punctiferalis disclosed by the invention, the specific components alpha-pinene oxide, methyl glucoside caprylate and leaf acetate are combined and proportioned, and the alpha-pinene oxide, the methyl glucoside caprylate and the leaf acetate respectively play roles in three links of smell attraction, nutritional requirements and host recognition, and are mutually promoted and complemented and synergistic, so that the attraction, attraction and gathering effects of the food attractant on dichocrocis punctiferalis adults are improved; the trapping and killing effect can be greatly optimized, powerful support is provided for green and efficient prevention and control of dichocrocis punctiferalis, agricultural production loss can be reduced, and the quality of agricultural products and agricultural ecological safety are guaranteed.

The application belongs to the technical field of oil and gas field chemistry, and particularly discloses a water-soluble lubricant resistant to calcium salt. The water-soluble lubricant provided by the application comprises the following components by weight: 64-68 parts of deionized water, 2 parts of sodium dodecyl polyoxyethylene ether (3) sulfate, 14-16 parts of polyethylene glycol monobutyl ether 500, 8-11 parts of propylene glycol block polyether L-64, and 7-8 parts of methyl glucoside polyoxyethylene (120) ether dioleate. The water-soluble lubricant has the advantages of excellent salt resistance and good lubricity, and can be used as a lubricant for high-salinity brine completion fluid with bivalent salt not higher than 400000 mg / L or a lubricant for brine drilling fluid with bivalent salt not higher than 85000 mg / L.

This invention relates to the field of oil and gas field drilling technology, and discloses a waterproof locking agent for drilling fluid, its preparation method, and a treatment agent for oilfield exploration. The method includes: (1) dissolving reactants A, B, and C in water to obtain mixture I; (2) contacting mixture I with reactant D and a surfactant to obtain mixture II, and then subjecting it to an irradiation polymerization reaction; (3) pulverizing, filtering, washing, extracting, and drying the obtained crude product to obtain the waterproof locking agent; reactant A is selected from at least one of methyl glucoside, chitosan, cyclodextrin, cellulose, and lignin; reactant B is an amide monomer containing an alkenyl group; reactant C is a quaternary ammonium salt monomer containing an alkenyl group; and reactant D is a hydrophobic monomer containing a phenyl group. This waterproof locking agent can effectively reduce the surface tension of the aqueous phase and the interfacial tension between oil and water, and can effectively prevent damage to core permeability caused by oil-water emulsification and water-locking effects.
