衬管切割、打捞联作工艺

LINER CUTTING-FISHING JOINT OPERATION TECHNOLOGY

随着油气开发的不断深入 ,在井网密度越来越大 ,征地困难 ,环保要求越来越高的形势下 ,修井已成为整个油气开发过程中一项必不可少的工作。衬管完成井传统的割、打捞分步进行处理方法存在施工周期长、劳动强度大、修井成本高等问题。衬管切割—打捞联作工艺的应用有效地解决了上述问题。文章详细介绍该项工艺的特点 ,工艺施工及应用效果分析。

Because the well pattern density is getting lar ger and larger,to solicit for land being difficult,owing to the unceasing deepen ing of oil and gas development and the requirements of environmental protection are higher and higher,well workover has become a necessary work in the whole pro cess of oil and gas development.The traditional treatment method separating the fishing from the cutting in a liner completion well is of some shortcomings,suc h as a long operating cycle,strong labour strength and high workover cost,etc.,a nd these shortcomings may be effectively overcome by applying liner cutting fis hing joint operation technology.The properties,operational procedure and applied result analysis of this technology are introduced in the paper.
