摘要:
针对南海珠江口盆地E边际油田大位移井开发中面临的地层界面不明确、储层非均质性强、油柱高度低等地质风险难题，创新性引入了基于超深探测和高分辨率电阻率联合反演的随钻储层实时描绘技术，钻井实施准备阶段结合研究区地质情况，通过模拟研究区地层电阻率响应建立了研究区地质风险规避策略。钻井实施过程中利用实时反演储层顶面深度和构造形态有效保障了优质储层的钻遇率和油柱高度。研究结果表明该技术在南海地区首次实现5个地层界面及6个薄储层（厚度<2m）的实时精准识别；成功实现优质储层（油柱高度≥8m）的全井段动态追踪；指导实时地质导向优化，保障完成亚洲深水区大位移开发井的实施。本技术构建的“地质—工程—经济”一体化开发模式，成功保障了E边际油田的经济有效开发，为全球深水边际油气田经济开发提供了创新性解决方案。
Abstract:
To address the geological challenges encountered in the development of extended-reach wells in the E marginal oilfield of the Pearl River Mouth Basin， South China Sea， including ambiguous formation interfaces， strong reservoir heterogeneity，and low oil column height，this study innovatively introduced a real-time reservoir delineation technology while drilling based on ultra-deep detection and high-resolution resistivity joint inversion. During the pre-drilling preparation phase， a geological risk mitigation strategy was established through numerical simulation of formation resistivity responses specific to the study area. Throughout the drilling operations，real-time inversion of reservoir roof depth and structural configuration effectively ensured optimal reservoir penetration rate and maintained sufficient oil column height. The results demonstrate that this technology has achieved the first real-time precise identification of five formation interfaces and six thin reservoirs（thickness<2 m）in the South China Sea region. Successful dynamic tracking of high-quality reservoirs（oil column heigh≥8 m）throughout the entire well section was realized， enabling optimized real-time geosteering that facilitated the completion of extended-reach development wells in Asia′s deepwater area. The integrated “geology-engineering-economics”development model established by this technology has not only ensured the cost-effective development of the E marginal oilfield but also provides an innovative solution for the economic exploitation of global deepwater marginal oil and gas fields.
