兴隆台油田CG6区块构造特征研究

Study on Structural Characteristics of CG6 Block in Xinglongtai Oilfield

兴隆台油田CG6区块是近年来辽河油田重要增储建产目标区块,其重要目的层为中生界。兴隆台潜山带为中生界与太古宇双层结构潜山,受到早期构造运动的控制,该区构造破碎、断裂复杂,地震成像品质较差。本文从区域构造特征入手,采用新处理的三维地震资料对CG6区块地层特征、构造形态、断裂组合深入分析,落实有利圈闭,结合成藏规律研究明确的部署有利区,指导了勘探开发部署。

Block CG6 in Xinglongtai Oilfield is an important target block for increasing reserves and production in Liaohe Oilfield in recent years. Its important target bed is Mesozoic. Xinglongtai buried hill zone is a buried hill with Mesozoic and Archaeozoic double-layer structure. Controlled by the early tectonic movement, the structure in this area is fragmented, the fault is complex, and the quality of seismic imaging is poor. Starting from the regional structural characteristics, this paper uses the newly processed three-dimensional seismic data to deeply analyze the stratigraphic characteristics, structural morphology and fault assemblage of CG6 block. The implementation of favorable traps and the combination with the study of reservoir-forming laws, has led to the deployment of favorable areas for exploration and development.
