| 摘 要： | 水力压裂产生的裂缝方向取决于地应力状态，垂直裂缝井压裂前储层中的应力分布，尤其是水平主应力方向控制着裂缝的起裂方位和延伸方向。分析了影响储层地应力场、裂缝方位及几何尺寸的因素，在此基础上，建立了压裂裂缝转向的应力场和渗流场数学模型并进行模型求解。对压裂裂缝转向机理进行了定量研究。 |

| Abstract: | Direction of fracture in hydraulic fracturing depended on in-situ stress. Before fracturing in vertical fracture wells, stress distribution, especially the main horizontal stress direction controlled the starting azimuth and extension direction of fractures. The factors influencing fractural stress field, fractural azimuth and its geometric size were analyzed. On the basis stated above, a model of stress field and percolating field of fractural diverting is established, by which it diverting mechanism is qu... |
