摘要： 基于莱州湾凹陷垦利17-1构造区新三维地震资料解释成果，对走滑盐拱带分布形态、形成机制、演化模式及成藏意义进行了研究。研究结果表明：①莱州湾凹陷古近系沙四段盐类来源主要分为深层热液和陆源输入2类，采用有监督的KNN模式多属性识别方法对盐拱形态边界进行刻画，识别出盐构造近乎南北向展布，通过截取南部、中部、北部地震剖面将盐构造形态分为整合接触非刺穿型、隐刺穿型、非整合接触刺穿型3类；②研究区走滑盐拱带为“走滑-反转-盐拱”三位一体的成因模式，重力沉积差异负载与走滑挤压耦合叠加作用下，盐拱构造形成了南北形态差异，盐构造主要经历了发育期—成熟期—再活动期3个主要演化阶段；③走滑盐拱带具有加速上覆烃源岩成熟、降低排烃门限以及良好的封盖作用，并控制了油气的运移成藏，研究区南部垦利17-1地区古近系沙三段及以下地层多形成盐墙侧封型油气藏，中北部垦利11-2地区深层东营组与沙一段、沙二段多形成岩性上倾尖灭或构造岩性型油气藏，馆陶组及明化镇组多形成刺穿地堑式断块型油气藏。

关键词: 走滑盐拱带, 热液成因, 陆源输入成因, 促进烃源岩早熟, 降低排烃门限, 封盖作用, 控藏作用, 沙四段, 古近系, 莱州湾凹陷, 渤海湾盆地

Abstract: Based on the interpretation results of new 3D seismic data in Kenli 17-1 tectonic area of Laizhou Bay Depression，the distribution，formation mechanism，evolution model and reservoir formation significance of strike-slip salt arch belt are studied. The results show that：（1）The salt sources of the fourth member of Shahejie Formation of Paleogene in Laizhou Bay Depression are mainly divided into two types：deep hydrothermal and terrigenous sources. The supervised KNN model multi-attribute recognition method is used to describe the shape boundary of the salt arch，and the salt structure is identified to be almost north-south distribution. By intercepting the seismic sections in the south，middle and north，the salt structure can be divided into three types：integrated contact non-puncturing type，hidden puncturing type and non-integrated contact puncturing type.（2）The strikeslip salt arch belt in the study area has a three-part genetic pattern of“strike-slip - inversion-salt arch”. Under the coupling and superposition of gravity sedimentary differential load and strike-slip extrusion，the salt arch structure forms a north-south shape difference，and the salt structure mainly goes through three main evolution stages：development stage，maturity stage and re-active stage（. 3）The strike-slip salt arch belt can accelerate the maturation of the overlying source rocks，reduce the hydrocarbon expulsion threshold，and have a good capping effect，and control the migration and accumulation of oil and gas. The formation of the third member and below of the Paleogene Shahejie formation in the south of the study area，Keli 17-1，mostly formed salt wall side sealing reservoirs. Lithologic updip pinch-out or tectono-lithologic reservoirs are mostly formed in the deep Dongying Formation，the first Member and the second Member of the Paleogene Shahejie formation in Kenli 11-2 area in the north of central China，and punctured graben-fault-block reservoirs are mostly formed in Guantao Formation and Minghuazhen Formation.

Key words: strike-slip salt arch, hydrothermal origin, origin of terrigenous input, promote source rock prematurity, reduce the hydrocarbon expulsion threshold, oil and gas capping action, reservoir control, fourth member of Shahejie Formation, Paleogene, Laizhou Bay Depression, Bohai Bay Basin
