摘要
在压裂管柱施工过程中,管柱在自重、井眼曲率、温度、内外压差等作用下,其受力和变形状态必然产生很大的变化,若应力或变形过大,将导致管柱破坏等事故。因此,压裂过程中的管柱受力变形已经成为影响压裂施工成败的关键因素之一。通过实例分析回接管柱的受力状态。
In the construction process of fracturing string, with the effects of string weight, hole curvature, tempera- ture, inner and outer pressure difference and so on, its force and deformation state will have a great change inevita- bly, if it is over stressed or excessive deformation, it will result in some operations accidents such as string destruc- tion. Therefore, string deformation affected by force in the process of fracturing has become one of the key factors affecting the success or failure of fracturing construction. This paper analyzes the stress state of tieback string by case study.
