摘　　要：中国大陆及沿海大陆架受西伯利亚、印度、太平洋三大板块俯冲、碰撞对接作用，造成中国各含油气盆地中的构造样式几乎都有着扭动应力因素的影响形成张扭或压扭与渗入、拆离断裂构造相伴生，使构造样式识别易误，本文根据中国实际提出拆离型与透入、渗入断裂构造的本质差异，并示其在地震剖面切片上不同的反映，以助于在地震构造解释中鉴别三大类构造样式。Continent and coastal shelves in China being affected by thrust and collision of three platerSiberia, India and Pacific Ocean, the structure geometries of oil-bearing basins exists soaking-in and breaking-out structures under the affection of sharing compressive stress and sharing tensile stress, resulting in wrong identification of structure models. This paper presents the inherent differences among the soaking-in, breaking-out and pentrating structure, and shows the different reflections on the seismic profile, assisting in identification of three plates in seismic structure interpretation.
