水平井分段酸压管柱技术研究

Survey on Segmental Acid Fracturing String Technique of Horizontal Wells

针对建南气田水平井层段的非均质性差异和破裂压力高的特点,需要采取分段高压酸化压裂措施改造。设计水平井分段高压酸化压裂管柱,通过管柱受力分析,达到优化管柱设计,工艺可行,耐高压,易解封的目的,为水平井分段高压酸化压裂措施施工提供一种有效的管柱工艺技术。

Segmental acid fracturing method under high pressure needs to be adopted to handle the heterogeneity differentials and high fracture pressure typical of the horizontal well intervals in Jiannan gas field.Force analysis will be conducted during the design of segmental acid fracturing strings to achieve better design effect,feasible crafts,high pressure tolerance and easy unset features thus providing an efficient string craftsmanship for high-pressure segmental acid fracturing strings of horizontal wells.
