    摘要:

    岩屑是反映地层资料的重要依据,在实验条件下岩石的可钻性与岩屑的分形维数存在明显的相关性,但现场岩屑的几何特征及粒度分布受到钻进过程中多因素的综合影响,不同条件下获得的岩屑粒度分布规律不同。因此采用分形理论对不同工程及地质条件的岩屑进行分析,总结各因素对岩屑分形规律的影响及其影响程度。结果表明:岩屑粒径分布具有良好的分形特征;现场岩屑分形维数是对井下各种因素的综合表现,比较符合实钻情况;等破碎概率Pc是判断钻进效率的参数之一,可通过调整钻进参数降低Pc值,提高机械钻速。

    Abstract:

    Cuttings are important evidence for the formation research, and there is a significant correlation between rock drillability and fractal dimension in Lab, but the geometric characteristics and particle size distribution of cuttings are affected by multiple factors during the drilling process, particle size distribution is different for cuttings obtained under different conditions. According to fractal theory, the cuttings of different engineering and geological conditions are analyzed to sum up the influence and influence degree of various factors to fractal law of cuttings. The results show that the cuttings particle size distribution has good fractal features; the cuttings fractal dimension is conform to the real drilling situation; and equiprobable breaking Pc is one of the parameters to judge drilling efficiency, Pc value can be reduced by adjusting drilling parameters to improve ROP.
