摘　　要：依据颗粒紧密堆积原理,在理想充填理论基础上,以储层孔喉尺寸分布和暂堵剂的粒径分布匹配关系为依据,建立了一种更为科学、有效的优选暂堵剂颗粒尺寸和分布的复配暂堵新方法。介绍了利用理想充填理论及研制的软件开发的保护油层钻井液在大港油田的成功应用情况。试油报告等资料证明,试验井日产油量高于邻井,充分说明了建立起的理想充填暂堵新方法可有效地保护中、高渗储层。A more effective method of optimizing particle sizes and their distribution was established based on ideal packing theory and relationship between the size distribution of reservoir pore throats and plugging agents. The successful application of drill-in fluid formulated using ideal packing theory and a software is introduced in this paper. Well test results showed that wells using the new drill-in fluid had higher production rate than offset wells.
