A new temporary plugging agent was developed to solve the problem of insufficient plugging performance of existing gel profile control and water shutoff. The organic material with temperature sensitivity and phase change function is assembled on the surface of the matrix material with high stability and good plugging performance by multi-layer assembly technology, and the composite gel profile control agent with multi-level structure is prepared. Research shows that the prepared profile control agent has a certain salt tolerance, and the inhibitory effect of CaCl₂ is greater than that of NaCl. When the C₂₅H₅₂ content is 3.6%, the multi-layer assembled profile control agent prepared by it has the best water absorption performance. When the temperature is 60 °C, the multi-layer assembled paraffin profile control agent prepared has the best water absorption effect.
