油管打孔器在海上油气田中的应用研究

摘要

针对油气井修井作业时，Y型接头生产堵塞器无法打捞或者循环滑套无法打开，导致起测试管柱前无法进行循环洗井、压井，或者生产滑套无法打开而又需要该层产出时，采用钢丝作业下入油管打孔器，在特定深度在油管进行打孔，以便油套连通，建立循环、流通通道。该油管打孔器已经广泛运用于海上采油平台的油气井中，快捷高效的解决问题，取得良好效果。%There is no passag eway to clean or kill well when Y plug not to be fished or circulation sliding sleeve not to be open in well workover. There is no production when a production sliding sleeve not to be open in a well . so perforate the tubing to get a passageway between tubing and annulus by tubing perforator with slickline. The tubing perforator has been widely used in field offshore and get good results.
