液氮泡沫水泥固井工艺及施工技术研究

摘要

When drilling in the bottom of the reservoir under low pressure,leakage or epigenetic cracks,it is prone to severe well leakage or kicks.This paper presents the liquid nitrogen foam cementing and construction technologies.%钻遇低压易渗漏、漏失层或浅表裂缝性等底层,容易出现严重的井漏或井涌事件.本文对液氮泡沫水泥固井工艺及施工技术进行了简单分析.
