大庆深井岩石性质和可钻性研究
摘要
深部硬地层快速钻进问题是深井、超深井钻井中的技术难题,是制约深井、超深井钻井发展的技术关键。深部井眼岩石力学的研究,特别是深部井眼岩石可钻性和岩石各向异性的研究,是解决深井、超深井钻井关键技术的重要课题。
本文就是从研究高温高压下深井岩石力学性质入手,对深井岩石的可钻性规律进行了研究。分析了钻井岩石力学在深井、超深井中的应用状况。通过高温试验对灰色晶质凝灰岩、泥岩,在恒定上覆应力的条件下,进行了不同围压、不同温度岩心的抗压强度、弹性模量、泊松比的测试,研究高温对岩石性质的影响。利用测井资料预测深层岩石可钻性及采用灰色聚类分析方法初选钻头和用主成分分析方法优选钻头,并通过深部井眼岩石可钻性、岩石弹性参数、岩石硬度和塑性系数的室内实验及分析,建立了深部井眼岩石可钻性与岩石力学参数间的相关关系,得出了深部井眼岩石可钻性与岩石力学参数间的相关方程,为提高钻井速度提供了依据。
