摘要: 提要：本文以地震信息为基础，应用多旋回先张后压中国含油气盆地构造演化史理论[1，2]，系统阐述了渤海湾盆地海域古近系—新近系地质结构演化过程和形成机制。特别是应用高质量的勘探地震信息，将渤海湾盆地海域石油构造样式划分为透入、拆离、渗入式三大构造样式，13类亚构造样式。最后以复合构造样式和复式油气藏（田）的描述作为构造样式的结语。Abstract: Abstract：Based on seismic information and applying multi-cyclic tension-followed-by-compression tectonic evolution theory for China’s oil and gas-bearing basins, this paper systematically expounds the evolutionary process and formation mechanism of Eogene—Neogene geological structure in the sea area of Bohai Gulf basin. With high-quality exploration seismic information, the petroleum tectonic styles in the sea area of Bohai Gulf basin are divided into three types (penetration, separation and infiltration) and thirteen subtypes. The complex tectonic types and compound oil and gas reservoirs (fields) are described in the end of this paper.
