小井眼分层注汽工艺技术的研究与应用

摘要

A steam distribution and injection process with layer selection is developed in this paper to be used for heavy oil sidetracking well.The down-hole thermal production sealer and supporting tools are designed to assembly effective process pipe string for layered steam distribution and layer selected steam injection in heavy oil sidetracking well.The process proves to be useful in improving the heavy oil production technologies to obtain optimum output.%本文研究开发了一套适用于稠油侧钻井注汽的分层配注汽工艺技术,通过设计有效的井下热采密封器及配套工具,并将他们合理组合,形成了稠油侧钻井分层配汽及选层注汽工艺管柱,以完善稠油开采工艺,发挥油层最大潜能,达到最佳开采效果.
