| 摘 要： | 位于塔里木盆地北部的雅克拉-大涝坝凝析气田经过多年的开采，其储层条件发生了很大的变化。由于原修井液体系固相含量较高，致使气井相继出现污染，储层也受到不同程度的损害。针对该气田储层特点，从增黏剂、降滤失剂、抑制剂和对储层孔喉具有暂堵作用的特殊粒子等入手，以生物聚合物、羟乙基聚合物纤维素类为主处理剂，并辅以降滤失剂、油溶性暂堵剂等开展了一系列实验研究，研制出保护储层的新型油溶暂堵型无固相修井液体系。现场试验表明，新型修井液体系性能优良，流变性易于调整和控制，抗高温能力强，API滤失量小于等于8 mL且HTHP滤失量很低，岩心渗透率恢复值超过80%， 具有明显的储层保护效果。

| Abstract: | After many years of development at the Yakela-Dalaoba condensate gas field, the reservoir conditions have changed significantly. The gas wells have been contaminated and the reservoirs are damaged to different degrees due to high solids contents of the previous workover fluid systems. Based on the lithology of the reservoirs, the characteristics of the porosities, the pore throats and the low permeability, a series of experimental studies have been made. First, the thickening additives, filtration-reducing ... |
