摘　　要：玛西斜坡区属于高压油气藏,油气水活跃,易发生固井窜漏,固井质量差。本文综合分析研究了玛西斜坡区的固井情况,发现水泥浆的性能严重的影响了固井质量。通过开展早强剂、膨胀剂、分散剂、降失水剂等多种水泥浆外加剂的实验评价研究,优化形成了适合于玛西斜坡区高压油气藏固井的胶乳防窜水泥浆体系。优化后的防窜水泥浆体系经现场试用表明,固井质量提升明显,研究成果可在开发钻井中推广应用,具有广阔的应用前景。Marcy slope area is high pressure gas reservoirs, oil and gas water was active and prone to cement- ing blow-by and cementing quality is poor. The slope Marcy was analyzed, and found that the cementing quality was affected serious by performance of slurry. The latex preventable cement slurry system for slope Marcy was op- timized by research early strength agent, sweller, dispersant and fluid loss. The field experiment for optimized sys- tem showed that the cementing quality improved obviously, the research results can be applied in the development of drilling, and has broad application prospects.
