珠江口盆地惠州凹陷烃源岩发育的主控因素分析
摘要
Abstract
According to the characteristics of geochemistry, petrology, sedimentology in source rocks, geochemical characteristics of the two sets of source rocks in Huizhou sag and the main controlling factors of high-quality hydrocarbon source rocks were comprehensively analyzed. The results show that the deep lacustrine source rocks in the Wenchang Formation which was formed in anoxic reducing environment have low aquatic organisms and algae input and good hydrocarbon potential. The River marsh coal mudstone in Enping Formation has terrigenous higher plants input, its oil-generating potential is less than the deep-lacustrine mudstone in the Wenchang Formation. Surface water was phytoplankton flourish and lakes had oxygen-poor environment in the Wenchang period , which conducive to the formation of high-quality source rocks. The heterogeneity of the source rocks were controlled by the change of control of the movements of sedimentary facies and base-level cycles, it is easy to form high-quality source rocks near the maximum flooding surface.关键词
