摘要/Abstract

摘要： 海拉尔油田兴安岭群储层是典型的含凝灰质储层，采用常规水基压裂液压裂时早期砂堵现象严重，成功率很低，严重制约着油田的开发。针对含凝灰质储层研究的交联乳化压裂液体系，油相体积分数很低，与凝灰岩储层岩石配伍性好。从交联乳化压裂液的物理特性、成膜阻隔作用、增黏阻隔作用以及两相流和贾敏效应理论研究了其稳定凝灰岩储层岩石的机理。现场试验75 口井，并扩大应用118口井，施工成功率达到97%，彻底解决了兴安岭群储层的压裂投产难题。

Abstract: Xinganling reservoir in Hailaer Oilfield is the typical tuffaceous reservoir.The early sand out phenomenon is serious when adopting the conventional water fracturing during the fracturing process，and the success ratio is very low，which restraints the oilfield development seriously.The oil phase consistency in crosslinked emulsion fracturing system which is researched for tuffaceous reservoir is very low，and the compatibility with the tuffaceous reservoir rock is rather well.The job implementation success ratio measured up to 97% in the field test for 75 oil wells and expanding application for 118 oil wells.It resolved the puzzle of the fracturing commission in Xinganling reservoir thoroughly.This paper researched the mechanism of steadying the tuffaceous reservoir rock from the physical characteristics，film forming cut off action，viscosifying cut off action，two-phase flow and Jamin action theory in crosslinked emulsion fracturing.

Key words: the crosslinked emulsion fracturing, film forming cut off action, viscosifying cut off action, the tuffaceous reservoir fracturing, the mechanism research
