【摘要】 最近的现场调查和实验研究表明,薄的平直的纯压实变形区(压实带)会出现于岩石中。由于压实带内孔隙减小而成为水库、蓄水层或油田油气的渗流障碍,压实带有重要的应用价值。对岩石中压实带的产生和演化进行了研究。结果表明,热效应使得压实带扩张,应变硬化效应使压实带缩小。更多还原

【Abstract】 By site investigation and experimental study, it is shown that thin and straight pure compaction bandmay occur in high porosity rocks. The compaction band may become the obstacle of underground water or oil andgas in rocks because of the decrease of porosity in compaction band. Therefore, it is important to study thecompaction band for oil and gas exploration and the construction of reservoir and tunnel. The evolution ofcompaction band is theoretically analyzed. It is shown that the strength of rock makes the band shrink while thetemperature makes the band extension.更多还原
