摘　　要：在大直径防砂管柱打捞过程中,由于防砂管柱与套管(特别是防砂管柱接箍与套管)的间隙较小,套铣难度较大,防砂管柱以切割后再进行打捞为主,严重影响了作业时效,提高了作业成本。因此,对于大直径防砂管柱打捞作业,优选割捞一体化技术。该技术成功应用于多口油气井大修作业中,取得了良好的效果。During the fishing of large diameter sand control string,the sand control fishing is carried out after cutting,becausethe gap between the casing and sand control string（especially the gap between the casing the coupling of the sand control sting）is too small to be milling,which prolongs the operation time and enhances the costs of the project. Therefore,cutting-fishingintegration is applied to the fishing of large diameter sand control string. It has been used successfully during workover of several oil andgas wells,and achieved good results.
