摘要
廊固凹陷内火成岩主要是新生代岩浆多期活动的产物。通过录井资料分析,主要以辉绿岩侵入体和水下喷发岩玄武岩为主要产状,在特定地质条件下发生烘烤变质作用,形成储集性能较好的板岩,与其它成藏条件相配置,即形成火成岩油气藏。
Most igneous rocks in Langgu depression are products of Cenozoic magma action, with diabase intrusion and subwater effusive basalt as major forms. Primary pore was undeveloped. The structural fractures generated in latter period made the igneous rock have reservoir capability. When diabase entering the enclosing rock of almost shale, baked metamorphism might occur under special geological conditions, resulting in slate which has good reservoir property, and forming oil and gas reservoirs through configuration with other reservoir forming conditions.
