Abstract: It shows that the relation between cavity and permeability of gelatinous solidified stone is exponential Labrid by synthetically studying on physical property of cement gelatinous solidified stone under high temperature and high pressure. The permeability of solidified stone is controlled mostly by increment of increased permeating agent and anti-flee agent in gel and its
strength is controlled by intensifier and the ratio of water and cement. Temperature and pressure are a limited conditions in solidifying. Results show that the system have many excellen properties such as high extruding strength(≥11 MPa), high compact strength (≥0. 5 MPa), high permeability(≥0. 8μm2),heat-resistance(≥115℃),oil-resistance and high salinity-resistance. Cement gelatinous solidified stone is suitable for sand control, water plugging, sand fracturing and barefoot completion and will be a potential gelatinous material.

Key words: gelatinous material, high permeability, high strength, well completion, sand control, sand fracturing
