渤海油田二次优快使丛式井的钻井效率提高40%以上,探井由于作业模式和井型的限制,如何提高效率和降低成本成为摆在我们面前的难题。通过创新扩展优快钻完技术体系,形成了渤海油田探井高效钻探新技术体系,包括一次就位多目标钻探技术、渤海探井井身结构设计模型、防斜打快钻井技术、提高深部机械钻速技术等。这一系列高效钻探新技术已在多口井取得成功应用,作业效率提高20%~30%,具有广阔的推广和应用价值。
Bohai Oilfield second-rate fast cluster wells drilling efficiency increased by 40% or more, exploration wells due to mode of operation and well-type constraints, how to improve efficiency and reduce costs become the challenge before us. Through the innovation and expansion of high-speed drilling finished technical system, Bohai Oilfield has formed a new exploration drilling technology system, including one in-position multi-target drilling technology, Bohai exploration well bore structure design model, anti-ramp drilling technology, drilling speed to improve deep penetration Technology and so on. This series of efficient drilling new technology has been successfully applied in many wells, operating efficiency increased by 20% to 30%, with broad promotion and application value.
