摘　　要：介绍了南海西部涠11-4油田角尾Ⅱ油组储层特征及潜在损害因素,通过室内大量的海水损害评价、粘土稳定剂评价、抑制速敏及盐敏试验、防腐研究以及射孔液体系损害评价等多项试验研究,提出一种适合于该储层的清洁盐水射孔液体系。经30多口井的现场试验证明,该体系成本低、工艺简单,保护油层效果优良,为涠11-4油田的顺利完井和投产起到了重要作用。Based on the understanding to reservoircharacter and potential damage factors of Wei 11-4 oil field in the west area of South China Sea, a low dam-age clear brine was proposed as perforation fluid after laboratory research, including sea water damage evaluation , clay stabilizer selection, velocity and salt sensitivity, corrosion control and perforation fluid damage evaluation. Tests at more than 30 wells indicate this fluid system has the advantage of low cost and low damage.
