摘要
为了实现经济开采,增大采气量,需要采用专用工具取消节流器或更换节流嘴。基于对某油田中井下节流器用打捞工具存在打捞成功率低、连续油管操作不易控制、无冲洗循环通道的问题分析,文章设计了一种新型打捞工具,采用可退式打捞筒方案,6颗黄铜销钉进行连接,通过设计计算及打捞筒拉伸试验表明,该打捞工具设计方案可行,可较好地满足该油田连续油管的施工作业,提高打捞作业的成功率。
In order to achieve economic recovery and increase gas production rate,special tools should be used to remove the throttle or replace the throttle. The existing fishing tool for downhole throttle is not easy to control by coiled tubing,no flush circulation passage and with low fishing success ratio. A new fishing tool has been designed with a release fishing barrel,connected with six brass pins. The tensile and shear tests of the pin and fishing tool show that the design scheme is feasible,able to meet the needs of coiled tubing operation on site,and the success rate of fishing is improved.
