| 摘要: |
| 板桥油田位于北大港潜山构造带东北倾没端,该油田沙河街组一段属于典型的重力流水道沉积。在系统的岩心观察基础上,结合400口井的测井曲线特征,将该区重力流水道划分为主水道、分支水道、水道侧翼、水道漫溢以及湖相泥5种微相。总结了各类微相的展布特征。综合动、静态资料,分析了沉积微相对储层物性的控制作用,探讨了不同微相砂体的渗流特征及水驱控制程度。研究认为下一步潜力区应是重力流主水道、分支水道以及水道侧翼砂体分布区,其中重点是重力流分支水道砂体分布区,区内还存在着丰富的剩余油资源。 |

| Abstract: |
| The Banqiao Oil Field lies at the pitching end in the northeastern part of the Beidagang buried hill structural zone. The first member of the Shahejie Formation in the oil field is built up of the typical gravity flow channel deposits. The gravity flow channels may be classified, on the basis of core examination and well logs for 400 wells, into five sedimentary microfacies, including main channel, distributary channel, flank channel, overbank and lacustrine mud microfacies. The emphasis of this paper is placed on the distribution of the abovementioned microfacies and their controls on the physical properties of the reservoir sandstones and water drive controls in individual sedimentary microfacies. The potential areas should comprise the main channel, distributary channel and flank channel sandstones, especially the distributary channel sandstones where there occurs prolific residual oil. |
