| 摘 要： | 辽河油田大民屯凹陷沈84—安12块为一复杂断块油藏,目前已进入开发中后期的高含水阶段。根据区内钻井、测井资料,应用高分辨率层序地层学基本原理,对沈84—安12块Es33段地层进行了多级次基准面旋回的识别与对比,分析了基准面旋回对沉积特征、储层物性、剩余油分布的控制作用,明确了基准面旋回内不同部位剩余油的富集规律:(1)基准面下降晚期、上升早期,砂体面积广,厚度大,储层物性好,剩余储量易于动用且多连片分布;(2)基准面下降早期、上升晚期,砂体面积小,厚度薄,储层物性差,剩余储量不易动用且零星分布;(3)基准面下降中期、上升中期,剩余油储量中等。研究证实运用高分辨率层序地层学的研究手段在高含水期的剩余油挖潜中具有重要意义。 |
| 关 键 词： | 大民屯凹陷 高分辨率层序地层学 基准面旋回 剩余油 |

| Abstract: | As a complicated fault-block reservoir, Shen 84-An 12 block in Damintun Depression of Liaohe Oilfield, has been at the late stage of development with high water content.Based on the drilling and logging data, and with the basic principles of high resolution sequence stratigraphy, the authors identified and compared base level cycles for Es_3~3 semi-member of Shen 84-An12 block.It was analyzed that the base level cycles could control the sedimentary characteristics, reservoir properties and the distribution of residual oil.Then it was made sure that residual oil had different enrichment features at different parts of the base level cycles, and they were: (1) late stage of base-level-dropping and early stage of base-level-rising, sand body has wide area, large thickness and good reservoir properties, and widely distributing residual oil is easy to develope; (2) early stage of base-level-dropping and late stage of base-level-rising,sand body has small area, little thickness, poor reservoir properties, and scattered residual oil is difficult to develope; (3) middle stage of base-level-dropping or rising, residual oil reserves is medium.So, the applications of high-resolution sequence stratigraphy, are very useful in development of residual oil in the high water content stage. |
| Keywords: | Damintun Depression high resolution sequence stratigraphy base level cycle residual oil |
