摘　　要：酸压管柱是酸压作业顺利实施的重要保障。在深井酸压过程中,管串长,摩阻大,泵压高,温差大,压力高,施工时间长,管柱受力情况恶劣,变形严重,如在管柱结构设计时未充分考虑因此因素,可能会造成封隔器密封失效,导致酸压失败。本文通过对两口酸压井管柱的力学分析及强度校核,对酸压管柱结构提出优化方案,对酸压管柱的安全施工提供了可靠依据。Acid fracturing string technology ensures successfully acid fracturing implement of oil development.During acid fracturing in deep well,string cluster is long;friction and resistance are big,pressure of pump is high;difference in temperature is big;pressure is high and construction time is long.Strings bear great pressure.Their transfiguration is serious.If all these factors are not taken into account before the structure design of string,packer will fail to work.Moreover,all that will lead to acid fracture fail.This essay puts forward the optimization proposal on acid fracturing string structure by mechanic analysis and intension check of two well practices.That will provide reliable basis for safe acid fracturing string work.
