Numerous graphs are provided which illustrate the parametric effects of fracture efficiency,spurt loss and fracture net pressure at the time of a screen-out on the pressure,derivative and slope behaviors after a TSO.
大量的图表都表明在采用端部脱砂压裂技术（tip screen-out (TSO)）后,压裂效率、初滤失、和裂缝净压力在因脱砂而产生的压力、微分和斜率变化时的参量效应.
