Technical field
The present invention relates to the water-rock reaction experiment device in the rock mechanics experiment field, can be used to study rock water chemistry effect and the rock mechanics micromechanism of damage of simulation reservoir under different water pressure conditions.
Background technology
A large amount of geotechnical engineering problems need be understood the characteristic of water-petrofacies interaction.Variation on slope, bank, storehouse owing to reservoir level, water-rock reaction is what to carry out under certain water pressure condition, the mutual effect of water-petrofacies will be influenced by water pressure, affect the safety of storehouse bank rock slope.At present people under general condition water-rock study on mechanism is more to water and rock, the water-rock reaction of research under different water pressure conditions is rarely found, does not also have a kind of instrument can simulate water-rock reagentia mechanism under the different pressures condition.
Summary of the invention
The objective of the invention is to provide a kind of can be to water-rock acting mechanism tester under the simulated reservoir water pressure state that experimentizes in the water under the different water pressure conditions-rock function Characteristics.
The object of the present invention is achieved like this: water-rock acting mechanism tester under a kind of simulated reservoir water pressure state, comprise the experiment instrument housing, housing top is provided with cover plate, the bottom is provided with base, be provided with sample holder in housing, cover plate is provided with water inlet and bleeder screw, and the pressure air bag places in the housing, the pressure air bag is connected with control pressurer system by the air bag gas admittance valve, and the water sampling mouth communicates with enclosure interior.Fan blade is installed in lower housing portion, is connected with motor.Between cover plate and base, be provided with by the reinforcing rod of reinforcing bolt.The pressure air bag is a hollow annular structure.Control pressurer system comprises gas bomb, is provided with air release between gas bomb and the tensimeter, and air pressure regulator is connected with tensimeter, and air pressure regulator is connected with the air bag gas admittance valve by connecting pipe.
Water-rock acting mechanism tester under the simulated reservoir water pressure state that provides of the present invention, the water pressure of the pressure chamber of this instrument is controlled by external pressure controller, can realize simulation rock and the interaction of water under different water pressure conditions; Experiment instrument is provided with dynamic and static water controller, the disturbance of simulated reservoir water simultaneously; The water sampling mouth is set, can conveniently obtains water sample, so that carry out the aqueous solution analysis.
The present invention also has simple in structure, easy to operate, safe and reliable characteristics; Can simulate the dissolution characteristics of rock under the water pressure state of storehouse, provide experiment porch for research large reservoir storehouse bank reproduces mechanism; The simultaneously all right disintegrating procedue of simulation rock under the flowing pressure state, cooperate the research of rock mechanics injury experiment, further clear and definite rock mechanics micromechanism of damage under moving hydraulic condition is for the protection of storehouse bank and geological hazards prediction forecast provide reliable experimental.
Utilize this instrument and equipment to finish the analysis and research work of more than 100 rock sample at present, obtained the excellent research effect, be described as follows below in conjunction with experimentation and the experimental result that obtains:
Rock soaks the water sample analysis that obtained afterwards in month and shows that under the water pressure condition of storehouse, great change has taken place the solubleness of rock, compares under 0 pressure condition, and Ca ion solubleness has increased nearly 4 times (recruitment is 5.0ppm); Opposite variation, the corresponding 0.03ppm that reduces take place in Si ion solubleness; Corresponding variation (table 1) has taken place in other ion equally.This variation is significant to geologic media variation of research reservoir area and water environment variation tendency.
