Study and Application of an Oil-based Gel Fluid for Sealing Induced Micro-fractures

  • 摘要: 四川长宁区块油基井段龙马溪组地层诱导型微裂缝发育,漏失频繁,油基堵漏手段主要为颗粒型桥堵,成功率低,耗时较长,为此研发了一套基于动植物油脂和环氧树脂的复合油基凝胶,可侵入地层微裂缝进行封堵,提高堵漏成功率。考虑到现场应用的可行性,室内对该凝胶的抗压强度、稠化时间、抗油基钻井液侵污能力进行了评价,并进行了模拟堵漏评价。结果表明,该凝胶的抗压强度可达5.1 MPa;凝胶的成胶时间可控制在3 h以上,提供了足够的安全施工时间;油基钻井液侵污对凝胶强度影响小,且不缩短稠化时间。该油基凝胶的各项性能指标表明其适用于油基段微裂缝堵漏。
