shear thickening fluid consisting of a material which swells in water (e.g. clay)paste capable of forming rapidly with a resistance of at least 1000 pa in the aqueous solution is used, and present in a concentration sufficient to form a paste.a material comprising a hydrophobic hydrocarbon non-aqueous material and a surface active agent and a reinforcing agent.and an aqueous solution containing a water-soluble polymer and water to swell in water.the clay and the polymer solution and water are kept separated by an intermediate stage of a surface active agent is a hydrocarbon.according to a preferred mode of execution.the clay encapsulee phase of surfactant hydrocarbon (oil phase) is suspended in a continuous phase comprising a polymer in water phase; however,a suspension of clay and polymer water droplets in a separate discreet and continuous oil phase are also possible in the same way as the common composition called "emulsdouble ion, as well as systems that are semi continuous.the oil phase control can the interaction between the polymer phase and the water phase, and a clay composite material is stable, does not reagissant.who can be a pump until such time as the oil barrier is broken by the application of a sufficiently high shear force.as a result of this failure, the material is mixed and publication, providing a semi-rigid high strength paste.several problems on the control of wells such as oil or gas expulsion can be eliminated by using the composite material as described above.the material is pumped down the shaft.as a result of the application of a sufficiently high shear, such as the output of the composite through openings in the forest, shear required to rupture the envelope of oil.the clay and the polymer phase react in water, giving rise to the
