摘要
通过文东地区岩石力学、岩石变形及渗流特性等测试,对异常高压油藏岩石变形特征及影响因素进行了系统研究。深入探讨与压力有关的外部条件,如加压平衡时间的确定、加压快慢、重复加压和多次循环加压等对岩石变形和低流速渗流的影响,最后提出此类油藏合理开发的建议。
The rock deformation characteristic and influencing factors in reservoir with abnormal high pressure were studied systematically through Wendong region core tests,such as rock mechanical property,rock deformation and percolation.The exterior condition,which refers to pressure parameter,plays an important role in rock deformation and percolation in low velocity.It includes pressure stabilization period,pressure-adding scale and repeated multiple methods.At the same timet,he related mechanism discussion was conducted,and suggestion is proposed for effective development of this reservoir at last.
