摘要:
为控制投资成本，提高勘探开发效率，油田加大了套管开窗侧钻井技术的应用力度。开窗侧钻施工中，由于环空间隙小，受小钻具振动、起下钻压力激动、高环空返速冲蚀，以及地层强水敏性等因素影响，井壁易失稳，导致起下钻遇阻、电测遇阻等井下复杂情况多发。为此，开展了KCl聚合物钻井液体系配方优化实验研究，并在CH113A、CSX23A侧钻井中成功应用，取得了理想的应用效果。研究表明： KCl聚合物钻井液具有抑制性强、流型好、性能稳定等特点，能满足开窗侧钻井对钻井液性能需求，为油田推广应用低成本开窗侧钻井开发提供了技术支持。
Abstract:
In order to control the investment cost and improve the efficiency of exploration and development，the application of sidetrack drilling technology for casing windows has been strengthened in Jiangsu Oilfield. During the construction of sidetracking with windows，due to influencing factors such as the small annular space gap，the vibration of small drilling tools，the excitation of tripping pressure，the erosion of high annular return velocity，and the strong water sensitivity of the formation，etc.，the borehole wall is easy to lose stability，resulting in complex and frequent downhole problems such as tripping resistance，reaming and electrical measurement resistance，and so on. Therefore，it was carried out studies on the formula optimization of KCl polymer drilling fluid system，and it was successfully applied in CH113A and CSX23A sidetracking wells，achieving ideal application effects. The research shows that KCl polymer drilling fluid has the characteristics of strong inhibition，good flow pattern，stable performance，etc.，which can meet the drilling fluid performance requirements of sidetrack drilling technology for casing windows，and provide technical support for the popularization and application of low-cost sidetrack drilling for casing windows in the oilfield.
