摘要
针对传统双侧向仪器分辨率已经不能满足油田开发后期对薄层评价的需求 ,开发设计了一种新型的双侧向测井仪。在仪器电极设计中 ,利用有限元仿真模拟软件精确模拟了多种电极系在二维地层中的响应 ,充分考虑了仪器分辨率的提高与电路硬件聚焦的物理限制的关系 ,确定了电极系结构。该仪器的理论分辨率达到 0 3m ,与微球聚焦测井仪的分辨率相近 ,而仪器的探测深度与传统双侧向测井仪基本一致。
A new type of duallaterolog tool has been developed in Daqing Well Logging Company. This new tool is designed to meet the thin bed evaluation in the mature oilfields. It has a resolution of 0.3 m which can be comparable with that of MSFL, and meanwhile, the investigation depth is nearly equal to that of traditional duallateral logging tool. The tool′s configuration is briefed and specification′s contrast with traditional duallateral logging tool detailed in this paper. A field example of this tool is illustrated to show its potential use in reservoir evaluation.
