摘　　要：介绍了大庆油田运用地面侧斜仪绘图法所研究的重复压裂法和重新定向测量的案例分析。此研究中,四种处理法均包括这样设计方案:注入石蜡球作为支撑剂、利用支撑剂试图使不同方向裂缝伸长、在不同井段打孔以注入石蜡球支撑剂。侧斜仪绘图结果显示,大多数重复压裂井都出现了裂缝重新定向。The paper presents case study on re-fracture treatments and reorientation measurement results by surface tiltmeter mapping in the Daqing oilfield. All the four treatments in this study include this design technique of pumping paraffin balsa as proppant, attempting to initiate fracture growth in a different orientation and perforating through different intervals. Tiltmeter mapping results indicate that majority of re-fracture treatment wells appear fracture reorientation.
