- 摘要:
- 针对白垩系油藏地层倾角大、夹层多、研磨性强及可钻性差等钻探难点,在该区块实施了一系列现场提速措施,包括防斜打快技术、水利振荡器试验、个性化PDC试验、钻具组合及钻井液性能优化等,旨在解决直井段钻进易斜、定向段工具面不稳、托压严重、井下复杂事故易发等严重制约钻速提高的技术难点,通过现场试验效果的分析,证明提速成效显著,为鸭K区块的优快钻井积累了成功经验。
According to the characteristics of higher formation clination, much interlayer, strong abrasiveness and poor drillability in the cretaceous reservoir , a series of measures had been implemented for drilling speed-up, including deviation control with drilling straight well, hydraulic oscillator test, personalized PDC bit test, assembly selection and optimization of drilling fluid performance, etc to solve technical difficulties restricting drilling speed-up such as oblique of drilling vertical wells, poor stability of tool face and serious “Pressure" in directional drilling and complex downhole accidents, etc. The analysis of field test results proved that drilling speed-up was effective, which accumulated successful experience for optimal and fast drilling in block Ya-K.
