Abstract: The technology of composite perforation for the crude bedding is increasingly studied and developed in recent years. When the technology was applied for the well 59 of Nanbaxian gas field and Ma well 8-1 of Mabei 1 in the north marginal area of Qaidam basin, the procedure can successfully remove the pollution obstruction in the single well reservoir resulted from the well killing liquid. The results show that the technology can be widely used for removing obstruction in area of cold lake oil field.

摘要： 原层复合射孔解堵工艺是近几年发展起来的一项射孔新技术。将此工艺应用于冷湖油田的南八仙油气田仙中５９井和马北一号油田马８－１井，结果表明，复合射孔解堵工艺完全适用于冷湖油田由于压井液造成的单井储层污染解堵问题，可作为增产解堵措施在冷湖油田大面积应用。
