超低渗透油藏非均质性差，部分区块一套油层发育多个小层，小层之间薄夹（隔）层发育，部分隔层仅有2～3m，封隔器难以准确座封，给小卡距井分层注水带来一定的困难。本文通过前期的调研分析，研究并开展了以磁定位和机械定位技术为主导的小卡距分注技术研究与试验，并对工具及工艺技术进行改进与完善，更好的适应了超低渗透油藏小卡距分注特点。

Ultra-low permeability reservoir heter ogeneity is poor, part of the block development of multiple small layer of a reservoir, a small layer between the thin folder (compartment) layer development, part of the compartment is only 2-3 m, the packer is difficuh to accurately packer, to bring some difficulties to a small card from the well stratified injection. Through the preliminary investigation and analysis, research and carried out a small card from the magnetic positioning and mechanical positioning technology to separate injection technology research and applications, and tools and the technology improved and perfected, better adapted to the characteristics of ultra-low permeability reservoir card from the separate injection.
