One-trip Casing Window Sidetracking Technologies for Offshore Oilfields
-
摘要:
针对常规开窗工具串难以通过狗腿度较大井段、锥式磨鞋易偏离导斜面、斜向器和磨鞋需要两趟钻送入等技术难点，研制了通过节流压差坐挂的斜向器及与其配套的次级磨鞋、挠性短节、开窗磨鞋等工具，形成了可一趟钻套管开窗钻具组合，该钻具组合实现了斜向器送入、坐挂及开窗作业。将一趟钻套管开窗作业分为5个阶段，推荐了相应阶段的磨铣参数，并制定了处理作业过程中复杂情况的技术措施，形成了较为完善的一趟钻套管开窗技术。渤海油田203口井应用一趟钻套管开窗技术进行了套管开窗，开窗成功率100%，平均开窗周期10.5 h，平均修窗周期2.6 h，与应用两趟钻开窗技术的井相比，开窗时间平均缩短2.4 h，提效22.8%。现场应用表明，一趟钻套管开窗技术能够提高开窗效率、降低钻井成本，可为海上油田稳产和提高采出程度提供技术支持。
Abstract:Given technical problems such as drilling difficulties for conventional window sidetracking tool strings when the well section has a large dogleg angle, and it is easy for the cone milling shoe to deviate from the guide slope, and for the whipstock to run separately from the milling shoe, a whipstock set by choke pressure difference and matching tools including a secondary milling shoe, a flexible coupling sub, and a window milling shoe were developed. Further, a BHA (bottom hole assembly) for one-trip casing window sidetracking was thereby created, and it accomplished the desired whipstock running, whipstock setting, and window sidetracking. A one-trip casing window sidetracking was divided into five stages, and recommended milling parameters were provided for each stage. Technical measures were formulated to deal with complications during the implementation process, and a suite of robust one-trip casing window sidetracking technologies was developed. These technologies were then applied in 203 wells in Bohai Oilfield for casing window sidetracking, with an average window sidetracking period of 10.5 h, a window repairing period of 2.6 h, and a successful window sidetracking rate of 100%. The average window sidetracking time of these wells was 2.4 h shorter than that of wells adopting two-trip window sidetracking technologies, with an efficiency increase of 22.8%. The field application showed that with higher window sidetracking efficiency and a lower drilling cost, the proposed one-trip casing window sidetracking technologies could provide technical support for offshore oilfields to stabilize production and enhance the degree of recovery.
