中文摘要: 通过对富台油田岩心裂缝观测,描述裂缝的几何特征、充填特征、力学性质等,进而确定裂缝的各项参数。研究结果表明,富台潜山发育大量构造裂缝,主要为北东—南西和北西—南东走向共轭剪切裂缝,同时可见近东西走向裂缝。裂缝基本为近垂直剪裂缝,开度集中在0.6~0.8 mm,以方解石半充填为主,体密度为5~10 m2/m3,北部较南部地区裂缝密度偏大,裂缝更为发育。
Abstract:Through core observation in Futai oilfield, we describe the geometric characteristics, filling characteristics and mechanical properties to conduct research on various parameters of fractures. The results showed that a great amount of structural fractures was developed in Futai buried hills, which formed two directions. One was NE-SW and NW-SE direction conjugated shear fractures that were dominant, another was nearly E-W. Fractures were mainly vertical ones with the characteristics of E-W shear fractures. The core fracture openings which were mainly half filled with calcite were mainly distributed in 0.6~0.8 mm. Its average volume density was between 5~10 m2/m3, and fractures developed much more in northern part than southern of Futai oilfield.
