摘要: 桥接堵漏技术是目前治理井漏的主要技术之一,但面对非常规油气藏的复杂地质条件,常规桥接堵漏材料适应性差,一次堵漏成功率低,并可能出现反复恶性漏失情况。为此,分析了桥接堵漏的作用机理,梳理了各类桥接堵漏材料的技术特性和发展现状,并提出了未来重点攻关方向。结果表明:强稳定性复合型桥接堵漏材料可解决封堵层易失效的问题,应围绕抗高温固化材料研发及注入工艺优化开展研究工作;自适应漏失通道型桥接堵漏材料可解决材料尺寸与裂缝宽度难以匹配的问题,应加大现场试验及应用推广;可解堵型桥接堵漏材料可解决储层堵漏和储层保护难以兼顾的问题,在酸溶性能评价、注酸流程优化及降解性能调控方面还有提升空间;可生物降解环保型桥接堵漏材料具有环境友好的独特优势,但在降解速率优化及降解程度的表征和控制方面尚需深入研究。该研究成果可为现场堵漏材料的选取提供技术参考,并指明桥接堵漏材料的发展方向。

Abstract: Bridging lost-circulation technology is one of the main technologies currently used to control lost circulation;however,under the complex geological conditions of unconventional oil and gas reservoirs,conventional bridging lost-circulation materials show poor adaptability,have a low one-time plugging success rate,and may cause repeated and worsening losses.Therefore,the mechanism of bridging plugging was analyzed,the technical characteristics and development status of various bridging lost-circulation materials were reviewed,and key future research directions were proposed.The results indicate that high-stability composite bridging lost-circulation materials can solve the problem of plugging-layer failure;research should focus on developing high-temperature curable materials and optimizing injection processes.Self-adaptive loss-channel bridging materials can address the mismatch between material size and fracture width;field tests and application promotion should be strengthened.Removable(unplugging)bridging lost-circulation materials can overcome the difficulty of balancing reservoir plugging and reservoir protection;there remains room for improvement in acid-solubility evaluation,acidizing procedure optimization,and regulation of degradability.Biodegradable and environmentally friendly bridging lost-circulation materials have unique environmental advantages,but further research is still needed on optimizing degradation rate and on characterization and control of degradation degree.The results provide technical references for selecting field lost-circulation materials and indicate development directions for bridging lost-circulation materials.

Key words: lost circulation, bridging plugging, plugging-layer stability, self-adaptive loss channel, biodegradation
