摘　　要：分析了压裂施工过程中“试挤、压裂、加砂、替挤”四个主要工序中泵压、排量随时间的变化曲线形态。现场施工时 ,及时分析施工曲线形态 ,可以合理调整施工参数 ,提前定性预测措施效果 ,确保压裂施工顺利。In a fracturing stimulation, relation curves of both pump pressure vs. time and discharge capacity vs. time are analyzed in four main working periods including extrusion test, fracturing, sand added and displacing test. Behavior analyses proper and timely for the curves can be used to adjust operation parameters,to forecast treatment effects,and to assure the fracturing operation safety and succeed.
