摘要： 地层评价的不得当常常致使欠平衡钻井方式的选择不当,进而引起复杂情况及储集层的严重破坏;同时欠平衡钻井设备庞大、动迁费用高,也会造成经济上的重大损失。在大量的欠平衡钻井现场实钻资料统计基础上,提出了欠平衡钻井方式对地层适应性评价的内容和步骤,这对现场合理选择欠平衡钻井方式具有一定的参考意义。

Abstract: The unreasonable formation evaluation often causes inappropriate choices of underbalanced drilling, resulting in some complex situations and severe damages of reservoir. Also, for its large equipment and high moving cost, significant economic loss will be made. Based on large amounts of underbalanced drilling site statistics, this paper presents the evaluations of underbalanced drilling adaptability to formation, including contents and procedures.

Key words: underbalanced drilling, formation fluid, hole stability, geologic condition, drilling process
