深井小井眼侧钻工艺技术发展趋势

摘要

Slim hole sidetracking technology is the main way of repairing the old wells,which is an important measure to improve the oil recovery of old wells for oilfield. By researching of the matching process technology and using slim hole sidetracking tools,drilling speed is improved,and high performance targets such as slim hole sidetrack drilling can be achieved,and it also can reduce the cost of investment.%小井眼侧钻就是老井修复的主要途径.小井眼侧钻技术是利用老井为油田提高采收率的重要措施.通过工艺配套技术和小井眼高效侧钻工具的研究和应用,完全可以提高钻井的速度,并可以实现小井侧钻的高效目标,还可以降低石油资源开发的成本投入.
