老井侧钻技术发展前景分析

Old well sidetracking technology development prospects

老井侧钻是提高单井产量、开发剩余油气藏的有效手段,可以大幅度降低投资成本的同时提高采收率。随着国内外油田对老井侧钻技术的应用日益增多,暴露了一些侧钻的难点,应该根据不同油气田的实际情况筛选合适的老井进行侧钻。

Old well sidetracking technology is a effective method to improve the single well production and to develop the remaining oil gas reservoir.Not only can greatly reducing the investment cost but also improving the recovery ratio.With the increasing application of sidetracking technology in old wells in oil fields at home and abroad,some sidetracking difficulties become visible.According to actual conditions of different oil and gas fields,those proper old wells should be selected for sidetracking.
