摘　　要：以河南下二门油田为研究对象,研究了泥浆处理剂及完井液对储层的损害程度,选择苛化泥(生产烧碱的副产物,粒径峰值13～35μm)、超细碳酸钙为架桥粒子和充填粒子,磺化沥青为可变形填充粒子,采用PAC或复合离子泥浆体系进行试验。结果发现,该技术暂堵效果好,渗透率恢复值高,施工简单,成本低,易于推广。在现场试验了10口井,效果明显。To deal with the problem of reservoir damage during drilling operation, temporary plugging technology was applied in Henan oil field. An optimized fluid system, containing sized calcium carbonate as bridging and filling particles, and sulfonated asphalt as sealing agent, is presented. Tests at 10 wells indicate that this system improves the return permeability of cores.
