Experimental Study on Percolation Characteristics of Trachyte with Dual Porous Media in Huangshatuo Reservoir
This paper aims to study the percolation characteristics of the trachyte dual porous media in Huangshatuo buried hill type reservoir, and explore the possibility of water injection for such a reservoir. A series of physical model experiments were conducted, mainly including the establishment of the imbibition experiment method of three-dimension rock sample with dual porous media, the core model preparation of trachyte and the choice of semblance coefficient. Besides that, microcosmic percolation characteristics evaluation tests (capillary pressure, relative permeability, oil-water displacement efficiency, imbibition experiment of dual media system and matrix rock system) were made, which resolved the complex percolation experimental problem of dual porous media reservoir microcosmic evaluation. Based on these experiments, this paper achieved systematic testing techniques for dual porous media oil reservoir percolation tests, and supplied invaluable basic parameters for the establishment of Huangshatuo special oil reservoir microcosmic evaluation and development method.
