摘要
深井下温度相当高,压强也十分大,再加上有盐膏层等,因此固井的难度很大。文章首先说明了深井复杂地层固井一般存在的困难,接着分析了深井固井的关键因素,最后针对提高深井固井质量提出了若干技术措施。
In the deep mine, the temperature is very high, the pressure is very large. There are rock and fat layers in the deep mine. So the difficulty of cementing is very large. In the paper, first, the general difficulties existing in deep well complex strata are explained, then the key factors of deep well cementing are analyzed, last some technical measures of improving deep well cementing quality are put forward.
