摘要
泥页岩的构成及泥页岩井壁表面和岩屑表面的特征对井壁稳定性的影响 ,是防塌技术研究领域值得不断深入研究的课题 ,是客观全面地研究防塌机理和方法的基础。本文综述了有关这方面的研究文献 。
This is a comprehensive review on this subject. The 1st part of this paper discusses the effects of shale composition and constitutents on borehole stability. The 2nd part presents the surface properties of shaly borehole and mechanical cuttings, including:①surface hydrating capacity of shale;②the role of microfracture growth in shale;③surface properties of principle minerals in shale (crystalline and amorphous clay minerals and non clay materials). In this review, emphasis is made on the bonding of shale particles as an important condition for borehole stabilization; the chemical activity and reaction driving force of fresh shale surfaces are considered to be the basis of complex physicochemical reactions between shale and body water in mud and must be used for antisloughing and shale inhibition.
