Abstract

The invention discloses a carbonate mineral dolomitization simulation study system and an application method thereof. The system comprises a reaction device, a carbon dioxide device, an Mg / Ca device, a multi-functional sprue (NaCl, Na2CO3, and NaHCO3 solutions and microbial liquid can be injected herein), a pH device, a sterile filter and a mineral storage chamber, and also comprises a stirrer and a temperature control device. The carbonate mineral in the reaction device can be subjected to dolomitization under the conditions of certain pressure, temperature, CO2 concentration, Mg / Ca fluid, different concentrations of NaCl and Na2CO3 / NaHCO3 solutions and microbial liquid, pH and the like; the solution is extracted by the sterile filter, and the parameters of dolomitization are measured; the generated mineral can be obtained from the mineral storage chamber. The carbonate mineral dolomitization simulation study system and the application method thereof provided by the invention can help to study the impact of different pressures, temperatures, Mg / Ca, salt concentrations, ionic strength and microbes on the dolomitization of carbonate mineral.

Description

technical field [0001] The invention relates to the technical field of carbonate rock mineral analysis, in particular to a carbonate mineral dolomitization simulation research system and a use method thereof. Background technique [0002] The main theoretical foundations of dolomitization of carbonate minerals include penecontemporaneous dolomitization, evaporative pump dolomitization, and burial dolomitization. The chemical reaction of dolomite formation is thermodynamically feasible, so researchers generally believe that the obstacles to dolomite formation are mainly kinetic obstacles, mainly manifested in the effects of alkalinity, salinity, temperature, pressure, ionic strength, and microbial action on dolomitization. control. Researchers generally believe that elevated pressure, temperature, salinity, alkalinity, and microbial action play a key role in breaking through the kinetic barriers of dolomite formation. Therefore, in the present stage of carbonate rock resear...
