| 摘 要： | 综合20口井岩心和496口井测井、录井及分析化验资料,对松辽盆地他拉哈-齐家地区姚一段葡萄花油层进行高分辨率层序地层研究,提出葡萄花油层北、西部为同沉积构造抬升控制的底部缺失的层序地层新格架。研究区最有利相带砂体为窄而细的末梢河道砂、薄层河口坝及席状砂体,而研究区北半部大量宽泛的厚层优质河道砂却不含油,为大面积含水区。研究总结发现,砂体发育与岩性油气藏分布均受控于一挠曲坡折带,坡折带以内为低水位体系域沉积质量中心,砂岩厚薄相间,可形成地层超覆圈闭;坡折带之下为3个层序低水位和水进体系域三角洲前缘砂体叠合区,发育的砂岩较薄且连通性差,是多层位岩性圈闭和上倾尖灭型圈闭发育区;坡折带之上以水进体系域平原相及前缘相的大量厚层河道砂体为主,但因连通性好,油气易散失,不易形成岩性圈闭,而成为大范围的含水区。坡折带"控层""控相""控砂""控藏"的理论在本研究区又一次得到极好的应用与验证。 |

| Abstract: | By using the high-resolution sequence stratigraphy theory,through depositional dynamic analysis,the cores of 20 wells and 496 well logging data,Putaohua reservoir of the Talaha-Qijia area in Songliao Basin is divided as 1 long-term base level cycles,3 medium-term base level cycles,8 short-term base level cycles,proposed a new framework with the sedimentary structure lifting control the north and west of Putaohua reservoir.Fine study of sedimentary characteristics reveals that the most favorable facies sandb... |
