In view of inhomogeneous distribution of fluid pressure, fault-valve behavior and the coupled equations of the current density and fluid flow within the Earth's crust, especially, the observed anomalies in electrical field showed a similar pattern of rapid starting and slow decay, some of these anomalies associated with episodical spouting from borehole or the increase of fluid pressure in wells, it is reasonable to consider that the source of precursory electrical field anomalies is the streaming potential mechanism.

The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles. Based on the molecular designing clues, this research selected three sulfonated copolymers as the stabilizers, i.e. the sodium 2-acrylamido-2-methyl-1propane sulfonate /acrylamide /disodium itaconate terpolymer, the AMPS/AM/N-vinyl pyrrolidone terpolymer and the sodium styrenesulfonate /IA copolymer. The preparation and characterization of the sulfonated copolymers were discussed, the high-temperature stability of the montmorillonitewater dispersion was characterized with the rheology, the filtration, the particle size distribution, the electrostatic properties, and the adorption of the sulfonated copolymers onto montmorillonite particles. At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.
