Study and application of key technology enhancement of shale oil horizontal well cementing quality for Well GY5-1-4H

  • 针对页岩油水平井水平段长、井眼条件复杂、套管居中难度大、顶替效率低、水泥体系性能要求高等制约固井质量提高的难题,开展钻井参数与钻具组合协同优化技术研究,优化钻具组合,满足提高固井质量对井眼清洁的要求,通过顶替效率模拟研究设计了理想套管居中度,并以此优选了整体冲压螺旋半刚性扶正器和清水顶替预应力固井技术,基于韧性化改造技术提高水泥石强度,降低杨氏模量,改性水泥石可以满足页岩油井水力压裂要求。使用上述页岩油水平井固井工艺配套技术,确保了GY5-1-4H井固井质量合格,为长水平段水平井固井提供了一套可借鉴的固井关键技术。
