| Abstract: | It is difficult for existing tools to fish in slip-type downhole throttle without failure,so a novel tool for slip-type downhole throttle with a compressible slip center rod is designed. The compressible slip center tion also indicates that rod will make the rubber retraction much easier. The Successful applica- this new tool shows some features such as easy operation, reasonable structure,reliable performance and easy processing. This new tool sion success rate of fishing in slip-type downhole throttle,shorten saves the fishing costs and thus plays an important role for fishing effectively improves the the time of fishing operat ions, work in the Sulige gas field. |
