课程名称：利用生产测井工具评估井的性能研讨会 课程概述：本研讨会由一位具有20年地质科学经验的专家主讲，旨在概述生产测井工具（PLT）及其在评估井下性能方面的应用。PLT涉及在有套管的井筒内运行专用工具，以收集关于流体流动和井况的数据。主讲者强调，与侧钻孔测井不同，PLT关注的是动态条件的测量。这一工具能够识别流体（如石油、天然气和水）进入或退出井筒的位置及其流速，并能够评估多相流动情况。 研讨会内容包括： 1. 常规PLT工具：涵盖流速测量的旋转仪、密度工具、电容工具（用于识别流体类型）及伽马射线/电缆测量工具（用于深度关联）。 2. 多阵列工具（MAPS和FSI）：探讨配备多个传感器的高级工具，提供对井筒更全面的视角。 3. 水平井流动：讨论在90度水平倾斜的井中流动情况，以及高于（92度）和低于（88度）该角度的偏差。 4. 循环：研讨会探讨流体循环现象，并通过插图展示重水相在偏斜井的下侧沉积，而轻油相则以更高的速度上升的过程。 5. 概念：解释相关概念并澄清使用PLT的目标是确定流动的性质和行为，包括准确性、精度、标定和流动模式等术语。 主讲者在结尾强调，完美的水平井并不存在。 议程： - 什么是常规PLT？ - 分析PLT数据需要什么？ - PLT工作绳如何运输到井下目标？（输送系统） - 为什么要进行PLT？（生产测井的好处） - 常规生产测井工具 - PLT操作概述与交付 - 我们为何需要所有这些PLT数据？（PLT评估目标概述） - 显著下行流（ADF）/循环 - 封井井中横流原理 - 水平井概述 - 多阵列生产测井工具 - 实用PLT原理和软件专业参考 通过本课程，学员将掌握生产测井工具的核心知识，了解如何应用这些工具对井的流动性能进行评估，从而更好地进行油气资源的开发和管理。
This seminar, presented b by 20 Years Geoscience Expert, provides an overview of Production Logging Tools (PLT) and their use in evaluating downhole well performance. PLT involves running specialized tools inside cased wellbores to gather data about fluid flow and well conditions.The presenter stresses that unlike open-hole logging, which focuses on rock properties, PLT measures dynamic conditions. It helps identify where fluids (oil, gas, water) are entering or exiting the wellbore, and at what rates. It can evaluate multi-phase flow.The presentation covered:Conventional PLT Tools: These include spinners (to measure flow velocity), density tools, capacitance tools (to identify fluid types), and gamma-ray/CCL tools (for depth correlation).Multi-array tools (MAPS and FSI): The speaker discusses advanced tools with multiple sensors offering a more comprehensive view of the wellbore.Horizontal well flow: The webinar explores flow in a well at a 90 degrees horizontal inclination, as well as deviations above (92 degrees) and below (88 degrees) that angle.Recirculation: The webinar focuses on the phenomenon of fluid recirculation, with illustrations of the way that the heavier water phase tends to settle in the lower side of a deviated well while the lighter oil phase goes upward at a higher rate.Concepts: The presentation explains concepts, and clarifies that the objective of using PLT is to determine the nature and behaviour of flow. It also explains such terms as accuracy, precision, calibration and flow regimes.The presenter concluded with emphasis that there is no such thing as a perfect horizontal well.AGENDA:What is Conventional PLT?What is Required to Analyze PLT Data?How is the PLT String Transported to the Downhole Target?
