AN APPROACH TO THE GENESIS OF CARBON DIOXIDE FROM THE THERMAL HYDRILYSIS MODELLING EXPERIMENT OF CARBONATE SOURCE ROCKS

摘要: 本文通过对3种岂碳酸钙(CaCO3)烃源岩加水热压模拟实验产生的二氧化碳(CO2)的分析,探讨了气体产物中二氧化碳(CO2)的成因,既有有机成因,也有无机成因。碳酸钙含量越高,岩石颗粒越细,无机二氧化碳产量越高。无机二氧化碳的产生会对含碳酸钙烃源岩有机质成烃有一定抑制作用。Abstract: Based on the analysis of carbon dioxide(CO2)produced by the thermal hydrolysis modelling experiment of three sorts of calcium-bearing carbonate(CaCO3)source rocks,the genesis of carbon dioxide(CO2)in the gaseous products is approached.There exists both organic and inorganic genesis.The higher the content of calcium carbonate and the finer the grains of rocks,the higher the yield of inorganic carbon dioxide.The generation of inorganic carbon dioxide restrains the organic material of calcium-bearing carbonate source rocks from producing hydrocarbons at some degree.
