Abstract

The invention discloses a plastic bead as well as a preparation method and applications of the plastic bead. The plastic bead comprises the following components by weight percent: 0.1-100% of polycarbonate and the balance of polystyrene. The preparation method comprises the steps of dissolving an oil-phase solute into an organic solvent, mixing uniformly to obtain a mixture taken as an oil phase which is polycarbonate, or a mixture of polystyrene and / or styrene monomer and polycarbonate; dissolving a dispersing agent or the dispersing agent and an emulsifying agent into water to prepare a water phase; sufficiently mixing the oil phase and the water phase so as to uniformly disperse the oil phase in the water phase to prepare emulsion; rising the temperature so as to volatilize the organic solvent and simultaneously solidify drops of the oil phase; and then separating the emulsion to separate a solid phase, and drying to obtain the plastic bead. According to the plastic bead and the preparation method, the environmental conservation is good, the process is simple, the problem of white pollution can be solved, and the application is wide.

Description

technical field [0001] The invention relates to the field of oil exploration, and furthermore, relates to a plastic pellet and its preparation method and application. Background technique [0002] With the development of oil exploration, the drilling depth continues to increase, and the number of cluster wells, high-inclination directional wells and horizontal wells is also increasing rapidly. Avoiding pipe sticking, reducing drill torque, and reducing drill string wear have become urgent solutions Problem, adding lubricant to the drilling fluid can effectively avoid accidents such as pipe sticking. Compared with liquid lubricants, solid lubricants are added to the drilling fluid in the form of solids to lubricate the well wall and prevent sticking and sticking. It has the advantages of convenient transportation, no fluorescence, and good lubrication performance. The currently used solid lubricants for drilling fluids mainly include the following two types according to the...
