密集交叉井网井眼轨道精确制导技术的应用

Application of Hole Trajectory Precision Guidance Technology for Dense Cross Well Network

摘要:

本着充分依托原有海上油田设施降本增效原则，渤海Q油田在原有生产平台附近新建井口平台、对原有密集井网成功实施了整体加密调整，作业难度急剧增大。通过老井眼数据再处理、新井轨道设计优化、轨道防碰设计、防碰监测等手段形成密集交叉井网井眼轨道精确制导技术。该技术的成功应用提高了作业时效，有效保障了在老油田密集交叉井网整体加密井眼轨迹的顺利实施、减小了碰撞风险。

Abstract:

In line with the original cost reducing and benefit increasing principles for offshore oil field facilities, wellhead platform was newly built near the existed production platform in Bohai Q oil field and the overall density increasing was carried out in the original dense well network, the operation difficulty increased rapidly. By means of the old borehole data processing, new well trajectory design optimization, anti-collision trajectory design and anti-collision monitoring, hole trajectory precision guidance technology for dense cross well network is developed. By the successful application of this technology, the work efficiency is improved, which effectively ensures the smooth implementation of well trajectory density increasing in dense cross well network of old oil field and reduces the collision risk.
