%X 义东2013三维工区位于义东断裂带处，义东断裂带是目前评价成藏最为有利的地区之一。近两年针对深层沙三段、沙四段岩性油藏钻探单井获得成功，但未实现区带建产，主要表现出沙四段岩相和厚度变化快，沙三段扇体包络面不清晰，断裂带成像问题复杂等问题。本研究通过对该区域进行断裂带构造研究，聚焦于义东断裂带构造、断裂体系精细描述，通过详细的地质勘探与分析，研究该区域的构造、断裂体系的平面特征。本文针对义东断层的组合和下降盘主要标志层和目的层开展研究工作，为后续储层预测以及开发目标优选奠定基础。
The Yidong 2013 3D work area is located in the Yidong fault zone, which is currently one of the most favorable areas for reservoir evaluation. In the past two years, the drilling of single wells targeting the deep lithologic reservoirs in the third and fourth members of the Shahejie Formation has been successful. However, the zone’s production has not been achieved. The main problems manifested are the rapid changes in lithofacies and thickness of the fourth member of the Shahejie Formation, the unclear envelope surface of the fan body in the third member of the Shahejie Formation, and the complex imaging problems of the fault zone. This study focuses on the detailed description of the structure and fault system of the Yidong fault zone, and studies the plane characteristics of the structure and fault system in this region through detailed geological exploration and analysis. This paper carries out research work on the combination of the Yidong fault, as well as the main marker layers and target layers on the downthrown side, laying the foundation for subsequent reservoir prediction and the optimization of development targets.
