三塘湖盆地二叠系火成岩分布及其对烃源岩热演化的影响
PERMIAN IGNEOUS ROCK DISTRIBUTION AND ITS INFLUENCE TO THE THERMAL EVOLUTION OF SOURCE ROCK IN SANTANGHU BASIN
摘要
Abstract
Through the studying of thermal evaluation relationships between igneous rock and source rock, it shows that igneous rock directly affects thermal evaluation of source rock. The main kinds of igneous rock are basalt, andesite, diabase and tuff etc in Permian. The effusive rock such as basalt, andesite and tuff have very little effect on evaluation of organic matter in source rock, and only intrusive rock such as diabase whose temperature can be kept in a long time and influent maturity evaluation of organic matter. The greater the thickness and the extent of diabase, the better effect on source rocks. It is estimated that the influent vertical depth is less than 200 m. If the scope of diabase is clear, it is facilitate to know the thermal evaluation and hydrocarbon-generating capability of source rock.关键词
