在石油地质工作中,利用岩石中CaO、MgO、SiO_2和Al_2O_3的含量做储集岩类型划分、孔隙度、渗透率和油藏储量计算及地层划分和沉积环境的研究等。但常规的化学分析方法速度慢,消耗大量的人力、电力和试剂,因此远远不能满足地质科研工作的要求。本方法以40%K_2SO_4作载体,碳粉为缓 In the work of petroleum geology, the content of CaO, MgO, SiO_2 and Al_2O_3 in the rock is used to make the classification of reservoir rocks, and the calculation of porosity, permeability and reservoir reserves, and the study of stratigraphic division and depositional environment. However, the conventional chemical analysis methods are slow and consume a large amount of manpower, electricity and reagents, thus far can not meet the requirements of geological research work. The method takes 40% K 2 SO 4 as carrier and carbon powder is slow
