Plugging material as well as preparation method and application thereof

The invention relates to a plugging material as well as a preparation method and application thereof, and belongs to the technical field of petroleum chemicals. The preparation method of the plugging material comprises the following steps: growing calcium carbonate on an MXene material in situ to obtain a composite material, and then growing molybdenum disulfide on the composite material in situ to obtain the plugging material. The prepared plugging material is a heterojunction self-lubricating plugging material, has low friction coefficient, excellent self-lubricating performance, good compatibility with water-based drilling fluid, excellent high temperature resistance and high stability, and can effectively solve the technical problems of lubrication, torque reduction and friction resistance reduction in the horizontal well drilling process; when being used in water-based drilling fluid, the water-based drilling fluid additive can improve rock-carrying capacity and reduce plastic viscosity, and can realize
