摘要: 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。Abstract: Aiming at the problems of long horizontal section, complex wellbore conditions, difficulty in casing centralization, low displacement efficiency, and high performance requirements of cement system which restrict the improvement of cementing quality in shale oil horizontal wells, research on the collaborative optimization technology of drilling parameters and drill string assembly was carried out to meet the requirements of improving cementing quality for wellbore cleaning. In addition, the ideal casing centralization is designed by the simulation of displacement efficiency, and the integral stamping screw semi-rigid centralizer and the water displacement prestressed cementing technology are also optimized. Furthermore, the strength of cement paste is improved based on the toughness modification technology. The hydraulic fracturing requirements of shale oil wells can be met through ruducing the Young's modulus and using the improved cement paste. All these work ensured the cementing quality of Well GY5-1-4H, so as to provide a worth considering key technology for long horizontal well cementing.
