【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。
[Abstract]:Aiming at the difficulties of drilling in Cretaceous reservoir, such as large dip angle, many intercalation layers, strong abrasiveness and poor drillability, a series of measures for increasing the speed of the reservoir are carried out in this block, including anti-slant and quick drilling technology, water conservancy oscillator test, and individualized PDC test. The drilling tool combination and drilling fluid performance optimization are aimed at solving the technical difficulties such as easy deviation of drilling in straight well section, unstable tool surface in directional section, serious supporting pressure and easy occurrence of complex accidents in downhole. The analysis of the effect of field test is carried out. It is proved that the speedup effect is remarkable and the successful experience has been accumulated for the high speed drilling in duck K block.
