【摘要】：古龙南地区位于松辽盆地中央坳陷区齐家-古龙凹陷及中央长垣的南端,表现为“三鼻两洼”的构造格局。该地区葡萄花油层在不同的构造部位呈现不同的油藏类型、油水分布特征,针对油藏这种差异分布特征,本论文以葡萄花油层为主要研究对象,通过构造单元,断裂特征,储层发育特征,油水分布特征等方面的研究,总结全区不同构造单元油藏类型及油水宏观分布规律,结合成藏主控因素综合分析,建立油气分区成藏模式及有利区优选方法。本文在对研究区的构造精细划分以及储层发育特征的研究基础之上,对研究区189口探井进行精细油藏解剖,确定了油藏类型及其分布特征。在古龙向斜中心主要发育砂岩透镜体油藏,边部发育砂岩上倾尖灭、砂岩透镜体及断层岩性油藏;茂兴向斜以PⅠ4-PⅠ6小层微幅度构造油藏为主;新站鼻状构造和新肇鼻状构造以构造-断层油藏为主,由于储层差异,油藏边部油水关系不同;在各斜坡区,受不同地层形态与断层展布配置关系及储层发育特征,分别发育断层岩性油藏、构造岩性油藏及砂岩上倾尖灭油藏。在古龙南地区葡萄花油层源岩评价、输导通道、砂体连通性等因素综合分析基础上,对研究区不同构造区油气成藏模式进行了总结:(1)古龙和茂兴向斜区,优质储层控制的岩性油藏成藏模式;(2)新站、新肇和敖南鼻状构造区,为断层分割鼻状构造隆起的构造油藏成藏模式;(3)新肇斜坡和新站斜坡,断层遮挡断层-岩性油藏和反转背形构造-岩性油藏成藏模式;(4)英台斜坡,岩性上倾尖灭油藏成藏模式。
[Abstract]:Gulongnan area is located in Qijia-Gulong depression of Songliao Basin and the southern end of central Placanticline, which is characterized by "Sanbei and Liangwa" tectonic pattern. In this area, there are different reservoir types and oil and water distribution characteristics in different structural positions in this area. In view of this kind of differential distribution characteristics of reservoirs, this paper takes the Putaohua reservoir as the main research object, through structural units, fault characteristics, The characteristics of reservoir development and oil-water distribution are studied. The reservoir types of different structural units and the macroscopic distribution of oil and water in the whole area are summarized. Combined with the comprehensive analysis of the main factors of reservoir formation, the reservoir forming model and the favorable area selection method are established. Based on the study of the fine division of structure and the characteristics of reservoir development in the study area, the fine reservoir anatomy of 189 exploration wells in the study area was carried out, and the reservoir types and their distribution characteristics were determined. In the center of Gulong syncline, sandstone-lens reservoir is mainly developed, and the edge part is developed by sandstone updip pinning, sandstone lens body and fault lithologic reservoir, and Maoxing syncline is mainly composed of P 鈪，
