| 摘 要： | 在压裂施工作业过程中有可能在裂缝中形成砂卡,砂卡一旦形成必然会影响到压裂施工压力,为了准确计算裂缝中砂卡的位置,可以对压裂施工压力进行分析。通过做出压裂施工压力和施工时间的双对数曲线,可以确定砂卡发生后的压力响应数据,将这些数据进行线性回归,求得直线段斜率,然后根据求得的斜率和相关的裂缝参数,即可求出裂缝中砂卡的位置。这对于正确指导压裂施工作业以及获得优质裂缝具有重要意义。

| Abstract: | Sands can be jammed the fracture during the fracturing construction. If sands jam is effective, it can affect fracturing pressure. In order to exactly calculate the position of sands jam in the fracture, fracturing pressure can be analyzed. By drawing the double logarithmic curves of fracturing pressure and construction time, the data of pressure response could be obtaine after sands jam happened. By their linear regression, the slop of straight-line segment could be obtained. Then, the positio of sands jam in the fracture was calculated by the slope and correlative fracture parameter. It is very significant to correctly direct fracturing construction and obtain fracture with high quality. |

| Keywords: | fracture fracturing pressure sands jam double logarithmic curve |
