根据岩石的蠕变性质,分析油井套管所受外挤力与时间的关系,地层相对错动对套管作用的形式,同时对套管设计提出了新的建议。 According to the creep property of the rock, the relationship between the external squeezing force and the time of the oil well casing is analyzed, and the form of the casing effect caused by the relative dislocation of the earth formation is analyzed. At the same time, new suggestions for casing design are put forward.
