THE OIL/GAS POTENTIAL CALCULATED BY MATERIAL BALANCE AND THE APPLICATION IN GEOLOGY
-
摘要: 本文主要对各类型有机质生油气率的计算方法进行探讨。根据化学反应的物质守衡定律和油气的有机成因学说,干酪根生成的油气和与之伴生的水、二氧化碳、氮气等产物以及残余干酪根的总和,应与原始干酪根的总量相等。研究结果表明,物质平衡法计算的生油气率与模拟实验资料基本吻合,其误差不超过5%,完全可以满足科研和生产的需要。Abstract: The calculations of oil/gas potential of various types of organic matter are discussed in this paper. Based on material balance law of chemical reaction and organic origin of oil/gas, the total sum of oil/gas, water, carbon dioxide, and nitrogen generated from the kerogen plus the residual kerogen should be equal to that of tne initial Kerogen. The analysis in this paper illustrates that oil/gas potential calculated by material balance almost coincides with the result of experimental simulations with a variance less than 5% and it can meet the needs of geological researches and explorations of petroleum.
