Abstract:

For studying dissolution mechanism conditions of carbonate rocks driven by hydrodynamic pressure in different storage periods, the carbonate rocks in a hydropower station at Wujiang River was selected as a research object; and the simulation experiments by using self-developed pressure corrosion equipment in open system was proceeded which showed that with the hydrodynamic pressure rising (from 0 to 2.0 MPa), the dissolution rate of carbonate rocks are increased. The curve of dissolution rate is obviously changed. During the dissolution of the carbonate rocks, with the water pressure increasing, the chemical dissolution and the mechanism damage obviously as changing as the hydrodynamic increasing, the ratio tends to 1:1. The results show that there is a coupling relationship. Microcosmic research based on scanning electron microscope and mercury injection test, the dissolution not only affects on the surface of the rock produce secondary pore and secondary mineral, but also influences the inner pore structure, decreases the permeability and connection among the structural planes of rocks.

Key words: carbonate rocks, reservoir, dissolution, hydrodynamic pressure, simulation experiment
