本文论述了浙江省中新生代强烈的构造岩浆活动,对油气的保存条件带来了不可忽视的影响。具体分析了断裂、岩浆活动、沉积间断和盖层对古生代大型海相盆地和中新生代小型陆相盆地油气保存条件的影响程度,指出浙江省寻找天然气的条件优于找油条件,而浙北地区的保存条件较佳。 This article discusses the strong tectonomagmatic activities of the Mesozoic-Cenozoic in Zhejiang Province, which have an irreversible impact on the preservation conditions of oil and gas. The influence of faults, magmatic activities, sedimentary discontinuities and caprocks on the hydrocarbon preservation conditions in the Paleozoic large-scale marine basins and the Meso-Cenozoic small-scale continental basins is analyzed in detail. It is pointed out that the conditions for finding natural gas in Zhejiang Province are better than the conditions for oil discovery, The preservation of the area is better.
