将地质与工程方法相结合是评价裂缝方位的最好方法。起初,诸如卫星照片、航空摄影以及区域研究应该用来确定地面裂缝的走向。经验表明,油藏中裂缝大都同地面裂缝呈同一方向排列。其他资料包括定向取芯和井下照相所获结果。瞬时压力数据可提供横交裂缝的长度和方位。不同井组进行的压力脉冲试验有助于裂缝方位的确定。在二次采油中,过早的水窜以及注入的 The combination of geology and engineering methods is the best way to evaluate fracture orientation. Initially, such as satellite photos, aerial photography and regional studies should be used to determine the direction of the ground cracks. Experience has shown that most of the cracks in the reservoir are arranged in the same direction as the ground cracks. Additional information includes the results of directional coring and downhole photography. Instantaneous pressure data provide cross-crack length and orientation. Pressure pulse tests conducted in different well groups are helpful for the determination of fracture orientation. In the second oil recovery, premature water channeling and injection
