The invention provides an intelligent bridging particle, which is mainly prepared from a memory alloy framework material, a fibrous lost circulation material, a filling material and a suspension dispersing agent, wherein the memory alloy framework material is a memory alloy coated by a thermosensitive clad material; the fibrous lost circulation material is one or composition of several out of dacron super-short fiber, saw dust, cotton seed hull and peanut hull powder; the filling material is one or composition of two out of calcium carbonate superfine powder and elastic graphite powder; the suspension dispersing agent is one or composition of several out of sodium carboxymethyl cellulose, xanthan gum and hydroxyethyl cellulose; and the thermosensitive clade material is a mixture of PE andparaffin. According to the invention, after the clad material falls off, the memory alloy framework material can extend to form a grid structure, and then the grid structure is filled with the fiber material and the filling material so as to form a firm bridging plugging layer, which has relatively high loading capacity. The intelligent bridging particle has a relatively good plugging effect for fracture-cavity type leakage.
