Particularly, the drilling tool is used for drilling, digging and other projects of petroleum and natural gas, and has the following characteristics:
1. the slurry containing carboxymethyl cellulose can form a thin and firm filter cake with low permeability on the well wall, so that the water loss is reduced.
2. After the carboxymethyl cellulose is added into the slurry, the drilling machine can obtain low initial shear force, so that the slurry is easy to discharge gas wrapped in the slurry, and meanwhile, the broken materials are quickly abandoned in a mud pit.
3. The drilling mud, like other suspension dispersions, has a lifetime which is extended by the addition of carboxymethyl cellulose to stabilize it.
4. the slurry containing carboxymethyl cellulose is less affected by mold, so that it is not necessary to maintain a high pH value and to use a preservative.

The polyisobutene is colorless to light yellow viscous liquid or elastic rubbery semisolid, is tasteless, has an average molecular weight of 20-8700 ten thousand, is soluble in benzene and diisobutylene, can be mutually soluble with polyvinyl acetate, wax and the like, is insoluble in polar solvents such as water, alcohol and the like, and has good light resistance, heat resistance and oxidation resistance. The method is mainly applied to many fields such as petroleum additives, adhesives and the like. It can also be used as thickener, and can be used in combination with other materials to improve adhesion, flexibility, aging resistance, air tightness and electrical insulation.
in the preparation process of the lubricant for the pipeline earth moving machine, the temperature to be heated and the temperature to be raised are lower than the melting points of the components, so that the partial dissolution of certain raw material components is enhanced, and the mixing of the raw materials is accelerated. And a magnetic stirring device is adopted to stir the mixture, so that the mixing of all the raw materials is further accelerated, and the mixture is uniform. The stirring speed is not easy to be too high, the stirring time is not easy to be too long, and some raw materials are easy to decompose; the stirring speed is not easy to be too low, the stirring time is not suitable to be too short, and all the raw materials cannot be fully mixed and are not uniformly mixed.
