摘　　要：在石油天然气生产及盐业开采过程中，对于已下套管的井，要想实现多目标、多层位立体勘探开发油气藏．综合利用枯竭、低产老井以及难以处理的井下事故，时常需要实施套管开窗侧钻分枝井作业来达到钻探目的，以期用较少投资获得最佳效益。四川石油管理局川东钻探公司与有关方面合作，研制出一套系列会管（定向）开窗侧钻工具，并完善了相关工艺技术，在多口井的套管开窗实践中均获成功。该套工具及工艺技术性能稳定、安全可靠，且具有投资少、风险小、施工工期短、可操作性强等特点，适于推广使用。In the course of Producing oil-gas and salt, for realizing the multi-target and multi-level, vertical exploration and development of oil-gas reservoirs, comprehensively using the old wells of exhaustion and low production and reducing the accidents in downhole, the technology of casing window sidetracking branch hole of cased well is often utilized to lessen the cost of drilling and obtain more benefits. A set.of tools for casing window sidetracking branch hole is developed by Chuandong Drilling Company of Sichuan Petroleum Administration with the relative units. The set of tools and the technology have the characteristics of steady property, safety and reliability,less cost and risk, short construction time, operating reliably etc. and suit to use widely.
