摘要
在研究盐岩力学特性基础上,对盐膏层特别是深部盐膏层钻井后因地层蠕变挤压造成井眼失稳和固井后套管挤毁的机理进行了研究,并提出了适用于盐膏层蠕变挤压应力计算模型。针对新疆塔里木盆地北部某井具体实例,就盐膏层蠕变挤压应力进行了计算分析。结果表明,研究成果与实际观察到的现象相吻合。
Based on the investigation of creep behavior of salt rock,the mechanism of casing failure and well-hole unstability resulting from the creep of salt rock in the deep salt rock stratum are investigated. The suitable numerical model is proposed in order to analyze the creep pressure on the casing. The analysis of creep pressure on the casing at the Tilimu basin of Xinjiang is carried out. The research results show the consistency between the calculation results and the practical measurement in the field.
