2011年12月12日,川庆测井公司与井下作业公司合作,在国内首次采用连续油管输送爆炸切割技术,完成门004-1-C1井的油管切割作业,为处理大斜度井和水平井工程事故提供了新的方法和思路。门004-1-C1井是西南油气田公司重庆气矿的一口大斜度开发井。为封堵长兴组,需在封隔器上部切割油管。由于这口井井斜大不能采用常规电缆传输方式只能采用连续油管传输方式将切割弹 On December 12, 2011, Chuanqing Logging Company cooperated with the underground operation company to firstly use the coiled tubing to deliver explosive cutting technology in China to complete the tubing cutting operation of the well 004-1-C1 well. In order to deal with the high-deviated well and water Hirai engineering accident provides a new way of thinking and ideas. Doors 004-1-C1 well is a large-scale development well in Chongqing Gas Mine of Southwest Oil and Gas Field Company. In order to block the Changxing Formation, it is necessary to cut the tubing at the top of the packer. Since this well can not use conventional cable well deviation, it can only use coiled tubing to transfer the cutting projectile
