侧钻新眼

This kind of wells couldn"t be repaired with present technical, or the repair costs are too high so they should be abandoned. But indeed the reservoir underground also has developing value. By side-tracking technical, we can use original well site, needn"t to land lease and relay ground pipeline, also a segment of original wellbore can be used and no new well needed. So the repair speed expedites, ensures the stabilization of productivity. At the same time it can supply new work-over technical for oilfield which can server for oilfield all over the world.

采用侧斜工艺技术进行修复可以利用原井场，不用重新征地，不需重新铺设地面管线，可以利用一段原井眼，不影响原来的井网布置和开发方案，不需再钻更新井，恢复原有的注采关系，修复速度也将大为提高，保证了油田稳产，同时在技术上为油田提供新的修井手段，利用此项技术可以为国内外其他油田服务。

Horizontal sidetracking technology has been developed so as to make full use of these old wells with shorter drilling cycle and less drilling cost by window opening and sidetracking in these wells.

为了充分利用老井眼的价值，采用侧钻水平井技术开采新的气藏取得了较理想的效果：对老井重新选层开发，充分利用了老井上部井段的套管资源，缩短了钻井周期，大幅节省了钻井费用。

The paper introduces the technology of optimization design of wellbore proile, the casing window-opening technology, and the barefoot laterally drilling technology. In view of such problems as the poor wellbore stability of large hole, the easily collapsed "Shuangshi bed", the barefoot laterally drilling, the different depth of production formations, the frequent trajectory adjustment, the prediction of torque and drag, and window entry of branch wells, systematic reasonable technical measures are established.

介绍了该井井身剖面优化设计、套管开窗及裸眼侧钻等新技术，针对表层大井眼井壁稳定性差、&双石层&易垮塌、裸眼侧钻、气层深度不一、轨迹调整频繁、摩阻扭矩预测及分支井所面临窗口再入等一系列技术难题，制定了一整套合理的技术措施。
