江苏油田侧钻井技术的研究和应用

Research and application of sidetrack drilling technology in Jiangsu Oilfield

江苏油田储层低产低渗,单井产量低,为了提高老区的采收率,降低钻井成本,侧钻技术在油田得到了广泛的应用。随着侧钻井越来越深,裸眼段越来越长,成本也随之增高。为了进一步缩短钻井周期,降低施工成本,开展了多方面的技术研究,有效提高了常规侧钻技术水平。通过现场施工案例验证,应用效果良好。

With low production and low permeability of reservoirs and low production of single wells,the sidetrack drilling technology has been widely used in Jiangsu Oilfield to improve the recovery rate of old well areas and reduce the drilling cost.As sidetracking wells become deeper and deeper,the open-hole section becomes longer and longer,and the cost increases.To further shorten the drilling cycle time and reduce the construction cost,various technical research has been carried out to effectively improve the level of conventional sidetrack drilling technology.The application effect is good as verified by field construction cases.
