井眼防碰监测技术在南海油田W9H的应用

目前，海上石油资源的勘探开发已进入一个新的阶段，丛式井、大位移井及水平井的应用正变得越来越普遍，特别是加密调整技术的应用，增大了井眼交碰风险，对钻井和油田正常生产构成了潜在威胁。利用定向井防碰地面监测系统在南海油田某区块的W9H实施钻井防碰监测，取得了良好效果。本文对该井防碰监测过程中不同工况条件下的信号特征进行识别、归纳，为定向井防碰地面监测系统和防碰工艺技术的不断完善提供技术与实践支撑。

The Application of Anti-collision Monitoring technique in the Well W9H of the South China Sea Oilfield

With the deepening of offshore oil and gas exploration and development, cluster well, extended reach well and lateral well are becoming more common, especially the infill well increases the risk of anti-collision, which poses a potential threat to the normal drilling and oil production. The anti-collision monitoring system, implementing a real-time drilling monitor for Well-W9H in the oilfield block of South China Sea. The paper gives identification and generation for the signal features with different operation on the anti-collision monitoring process, both the anti-collision monitoring system and technology could be further improved with technological and practical support.
