摘要：大庆长垣南部葡萄花及敖包塔地区构造上位于松辽盆地北部中央劫陷区大庆长垣背斜二级构造单元南部，主要目的层为姚一段的葡萄花油层。在分析各区带的油气成藏过程、油气藏形成机制和分布特点基础上，研究了葡葡萄花油层成藏模式。研究结果表明，构造主体及边部主要发育构造、构造--岩性以及岩性油藏3种油藏类型，其中构造主体大部分区块已操明开发，待评价区均处于构造两翼及斜坡区的构造一岩性及岩性油藏带内。进一步分析研究分段生长断层传递带控砂、异常高压成藏条件，提出了油藏评价工作的3个转变，为研究区评
价部署指明了方向。同时，对研究区内油气成藏主控因素进行分析，明确了油气富集部位。关键词：大庆长垣南部；葡萄花油层；成藏模式；断层控砂；异常高压

Abstract: Putaohua and Aobaota regions are structurally located in the southem part of the secondary tectonic unit of Daqing Placanticline in the Central Depression of North Songliao Basin, the main target layer is Member-1 Putao hua oil reservoirs. On the bases of analyzing the petroleum accumulation process, mechanism and distribution of each region and belt, the accumulating modes of Putaohua oil reservoirs were researched. The study achievements show that three kinds of oil reservoirs are developed principally in the key and peripheral structures: such as struc-tural, structural-lithological and lithological forms. Among them, the most blocks of the former have been proven and developed, the unevaluated blocks are distributed in the two wings of the structures and in the belts of the latter two reservoirs of the slope zones; the petroleum accumulating conditions were further analyzed and studied for the sandbodies controlled by the transforming belts of the staged faults and moreover the abnormal high pressure, and then three kinds of the transformation were presented for the reservoir evaluation, thus the directions have been made sure for the evaluation and arangement of the region; at the same time, the main controlling factors of the pe-
