摘要
针对裂缝 -孔隙型储层特征和固井特点 ,研究水泥浆对储层的损害机理 ,并结合优质固井对水泥浆性能的要求 ,优选出了保护油气层的水泥外加剂 ,确定了适应各种井深的水泥浆配方。实践证明 ,这些配方性能优良 ,失水量低 ,防窜效果好 ,固井质量高 ,能减少对油气层的损害。
Based on the fracture-pore type reservoir characteristics and the damage mechanism of the cement slurry to reservoir,combined with the cementing features of wells at different depth and their requirements on cement sturry performance,cement additives are optimized for fracture-pore type reservoir protection.The cement slurry formulations for wells at different depth are determined.Practice indicated that these formulations have the characteristics of superior property,low water loss and high cementing quality,which can minize the formation damage.
