| Abstract: | The presented laboratory evaluating installation is of core flow type. 1-4 axial fractures of wideness 0.05-0.5 mm are made on the outer surfaces of cylinderical cores, natural or artificial, following the principle of Brazilian test of rock. With these fractured cores, a series of temporarily plugging and sheilding compositions are investigated to determine their plugging rate D for aqueous phase and permeability recovery H for oil phase. It is shown that the combination of a particulated oil soluble resin, TR 5, and fibrious material, HPS, in a standard brine with dispersant and wetting agent added is effective in temporarily plugging and sheilding of the fractured core samples and can be used in igeous (as in Block Shang 741) and other fractured reservoirs. |
