From the analysis, we can found that the azimuth of the perforation is very important for fracture shape and the effect of hydraulic fracturing operation.
分析表明，射孔方位对水力压裂裂缝的形态、压裂施工的效果至关重要。

The results from microseismic determine fracture geometry, azimuth, and fracture complexity.
从微地震的结果可以确定裂缝的几何形状、方位角和裂缝复杂性。

Then the azimuth of formation fractures is estimated; and with the joint use of zero offset P wave source VSP data, fast and slow shear wave seismograms are obtained to have fracture density.
