【摘要】 利用地震多属性分析等技术,对辽河坳陷滩海燕南潜山带中生界火成岩储层的分布、储层物性特征以及可能的含油气特征进行了初步预测。该火成岩以安山岩为主,钻时曲线普遍偏高,表明地层坚硬致密,一经构造运动等因素改造后,可以形成良好的裂缝性储层。本区溢流相火成岩含油气前景较好,应结合地震波形分类结果精细地圈定其分布范围,以作为今后勘探的有利地区。更多还原

【Abstract】 Oil and gas has been found in thick igneous rock drilled in Yannan Buried Hill Belt in recent years. The rock composed of hard effusive andesite has been good fractured reservoirs after undergoing reconstruction of tectonic movements. Seismic multi-attributes and coherency cube techniques have been applied to reveal distribution of the igneous rock and fractured zones,the reservoir features and the prospective area It is suggested that the wide-distributed Mesozoic igneous reservoirs in Yannan area will have a good potential of oil and gas resources.更多还原
