The invention relates to a chemical composite resin mounting agent for the oil-water well casing restoration, which can be applied to reinforcing work for the oil-water casing damage restoration when the stratum temperature is 40-110DEG C. The agent is characterized in that the agent comprises, by weight, 60-75% of a phenol and formaldehyde prepolymer, 10-20% of an epoxy phenolic resin F-46, 5-30% of an epoxy resin 6101, 1-5% of ethylenediamine, 1-5% of triethanolamine, 0.5-2% of acetic anhydride, 1-3% of dibutyl phthalate, 2-5% of glycol, 2-5% of polyvinyl alcohol and 0.1-0.2% of an ultrafine acrylic staple fiber. The agent has the following effect: the production capacity of the oil-water well is restored by rebuilding a composite artificial casing on the damaged and deformed casing well segment through combining the restoration reinforcing work for the damaged and deformed casing in the oilfield exploitation with a drilling and milling technology. According to the mounted casing, the tensile strength is 10.8-13.1MPa, the compressive strength is 13-87MPa, and the shearing strength is 9.2-28.9MPa.

The invention relates to a pesticide carbendazim degrading microbial inoculant and a preparation method thereof. In an agricultural production process, as pesticides are excessively used, high residues of pesticides in agricultural products and agricultural soil are caused, which brings a certain problem to safety of the agricultural products and sustainable development of the agricultural soil. A human ochrobactrum WNPA2 is cultured in a special liquid fermenting culture medium, fermentation liquor is collected for centrifugal separation to remove moisture in the fermenting liquor to obtain milk white thick somatic cells; by adding glycerinum and diatomite which are uniformly stirred and mixed, a white solid preparation, namely, the target product, is obtained. The preparation method provided by the invention is an efficient and economical environment-friendly pesticide residue treatment technology. The carbendazim degrading rate can reach 50% above, and the pesticide carbendazim degrading microbial inoculant has the advantages of being low in treatment cost, simple to construct, free of secondary pollution, small in environmental influence, etc.
