摘要： 裂缝的闭合或开启程度取决于地层的应力大小和裂缝面的粗糙程度。裂缝性地层对应力的敏感程度属于中等偏弱的水平。裂缝性油藏产量的快速递减不是因为裂缝的应力敏感性使裂缝闭合所致, 而是裂缝性油藏产量阶段特征的表现形式。

Abstract: Closure or openness of fractures in reservoirs depends on the stresses on and the roughness of fractures. Fractured reservoirs are middle-week sensitive to pore pressure. Rapid decline of production from fractured reservoirs is not due to the closure of fractures resulted by stress sensitivity, but the natural performance of periodical production behaviors of fractured reservoirs.

Key words: reservoir, fracture, stress sensitivity, reservoir pressure
