Abstract

Abstract

A comparative study was conducted to probe the feasibility of conventional and fixed-Al modified log (Q/K) graph on hot spring system. Lushan hot spring, Tanghu hot spring and Hengjing hot spring in Jiangxi Province were selected to reconstruct the reservoir equilibrium by log (Q/K) graph, and all the calculation were carried out by WATCH program. Due to the lack of Al in the water analytical data, only chalcedony and calcite intersected around 100 ℃ in normal log (Q/K) graph. So no equilibrium status or temperature could be reconstructed by this method. Calculated by the method by combining the fixed-Al method with the mixing factor, minerals association of laumontite, chrysotile, fluorite and chalcedony converged around 100-140 ℃ in fixed-Al modified log (Q/K) graph, which means the equilibrium status could be successfully reconstructed. These mineral assembles occurred in the borehole of Tanghu hot spring field. The calculating result corresponds with the real hot spring system, which might infer that the fixed-Al log (Q/K) graph could be used to reconstruct the reservoir equilibrium in hot spring system.
