摘　　要：粘土矿物堵塞地层后 ,使用土酸、氢氟酸酸化处理在现场应用效果有效期短 ,分析粘土矿物造成的堵塞除了粘土颗粒运移外 ,粘土膨胀应起主导作用。为此研制开发了以粘土缩膨为主的解堵工艺技术 ,在中原油田应用见到了明显效果 ,特别适用于酸化效果不明显的油水井解堵处理。The period of validity are shorten to make use of the mud acid and hydrofluoric acid to acidify when the stratum is blocked by the clay mineral , we have analysed clay that mineral lead to the fact to stop up,aside form the particle of clay moving,the clay should play a leading role while expanding. Therefor we developed the telenology of relying mainly on the fact that the clay contracts and expands can solve its jam . In using in Zhongyuan Oil Field,the result is obvious.expecially the result is not obvio...
