So we use the methods of combing and comparing correlation analysis and offset seismic profile to predicting the growth level of cracks of Xujiahe reservoir.

本文采用沿层相干拾取结合偏移剖面对比方法，对上三叠统须家河组砂岩储层的裂缝发育情况进行预测。

In a vertical seismic profile, offset is the horizontal distance between the source and the wellhead or the surface projection of the receiver in the case of a deviated well.

在垂直地震剖面中，偏移距是震源和井口之间的水平距离。在斜井的情况下，偏移距是震源和检波器在地表的投影之间的距离。
