摘要
开窗侧钻水平井钻井技术是降低钻井综合成本、提高老井原油产量的重要途径之一。本文分析了滴西14老井侧钻主要技术难点及制定了相应对策,并通过侧钻实例从方案设计到现场实际施工过程,提出今后滴西14井区老井侧钻优化改进、减少复杂、提速提效的方向。
The sidetracking technology is one of the important ways to reduce the comprehensive cost of drilling and increase the crude oil production of old well. This paper analyzes the main technical difficulties and corresponding measures of the old well sidetracking in DX14, and through the example of sidetracking from the project design to the actual construction process, the direction is put forward in optimizing and improving the old well sidetracking technology in DX14 well area,in reducing the complexity and increasing speed in the future.
