摘　　要：在水力加砂压裂施工过程中,仪表车显示屏上需要显示净压力大小,以便于控制施工程序,避免发生砂堵。通过实际经验以及参考文献资料,总结出较为实用的计算净压力的方法以及如何运用净压力双对数的斜率判断水力压裂过程中裂缝的增长情况,并且判断是否存在砂堵可能性,从而能够提前采取措施,预防砂堵造成的严重后果。In the process of hydraulic sand fracturing,the amount of net pressure needs displaying on the screen of measuring truck for the operators to control operating procedures and prevent sand plug.This paper introduces the practical method for net pressure calculation and the way of estimating the fracture growth in the process of hydraulic fracturing by means of logarithmic slope of net pressure,thus judging the possibility of sand plug so that measures can be adopted in advance to avoid grave consequences caused by sand plug.

关 键 词：加砂压裂 净压力 缝高控制 井底砂浓度 砂堵
