长期以来,石油行业中修井工艺一直惯用传统的修井技术手法,主要是以修井机、通井机和人工起下油管,同时结合特种车辆的配合来完成施工。文章以油田中油水井修井的工艺技术及修井作业的流程进行讲解,并通过实例来说明修井技术在油田中的重要作用,这样不仅减少了油田中事故的发生,更大大的加强了油田施工的质量,从而达到保护地层,以免使地层遭到二次污染,更有效的避免了对环境的污染,最终达到了修井效益的总体效益提高。
For a long time, the workover process in the petroleum industry has been traditionally used in the traditional workover techniques, mainly with workover rigs, wellhead machines and man-made tubing, combined with the construction of special vehicles. This article explains the process technology of workover well of CNPC oil well and workover process, and illustrates the important role of workover technology in oil field through examples. This not only reduces the occurrence of accidents in the oil field, but also greatly strengthens the oil field Construction quality, so as to protect the formation, in order to avoid secondary contamination of the formation, more effectively avoid the pollution of the environment, and ultimately to achieve the overall benefits of workover efficiency increase.
