摘要
顺北油气钻井区块多为深井、超深井,井下存在高温、高压、溢流、坍塌等复杂情况,钻井周期长、成本高,安全施工、提速提效成为加速该区块开发的关键所在。实践表明,日费制钻井管理模式促进了安全高效生产,取得显著成效。以顺北53-2H井为例介绍西北日费制井体系建设和运行情况。顺北53-2H井是顺北区块一口超深井,设计井深8147 m,该井采用了日费制管理模式,生产时效达到94%,平均机械钻速同比提高88.3%,钻井周期缩短15 d,大幅度节约了钻井成本。通过日费制井实践,进一步优化了日费制管理模式,为顺北油气钻井区块提供了一套可复制的日费制井管理模式和技术模板。
Shunbei oil and gas drilling block is mostly deep wells and ultra deep wells.There are complex downhole problems such as high temperature,high pressure,overflow and collapse,long drilling cycle and high cost.Safe construction,speed-up and efficiency improvement have become the key to accelerate the development of this block.The practice of the daily fee drilling management mode has promoted safe and efficient production and achieved remarkable results.Taking Shunbei 53-2H well as an example introduces the construction and operation of daily fee well system in Northwest China.Shunbei 53-2H well is an ultra deep well in Shunbei block,with a design well depth of 8147 m.The well adopts the daily fee system management mode,the production efficiency reaches 94%,the average ROP increases by 88.3%year-on-year,the drilling cycle is shortened by 15 days,and the drilling cost is greatly saved.Through the practice of daily fee system well,the daily fee system management mode is further optimized.It provides a set of reproducible daily fee well management mode and technical template for Shunbei oil and gas drilling block.
