摘　　要：对带封隔器的环空加砂压裂管柱在管柱自由下井、水力喷砂射孔和环空加砂压裂三种工况下的受力及变形进行了研究。建立了压裂管柱的受力模型,考虑了重力效应、温度效应、活塞效应、鼓胀效应及摩阻效应对压裂管柱的影响,分析了带封隔器的环空加砂压裂管柱在不同工况下的受力状况,计算了压裂管柱在不同工况下的变形量,从而为油田在环空加砂压裂过程中计算下入压裂管柱的长度提供理论依据。The force and deformation of annulus sand fracturing pipe were researched under following three conditions： pipe downhole, hydraulic jet perforation and annulus sand fracturing. The force model of fracturing pipe was established considering the influence of gravity effect, temperature effect, piston effect, bulging effect and friction effect on fracturing pipe.The force of annulus sand fracturing pipe with packer under different conditions was analyzed, the deformation of fracturing pipe under different conditions was calculated, which could provide the theoretical basis for calculating the length of annulus sand fracturing pipe.
