摘　　要：油井管柱在各大油田被广泛的应用于试井、压裂酸化、注水、采油等井下作业,它是油井作业、生产的主要承载和动力传递构件。在大位移、大斜度井中,油井管柱力学行为的研究已成为油气田勘探、开发和生产技术进一步发展亟待解决的关键问题之一。文章通过对三维弯曲井眼的几何描述,运用最小势能原理建立了三维弯曲井眼管柱的力学模型,为进一步分析压裂酸化、注水、测试等井下管柱及井下工具提供理论依据,具有较高的理论意义和适用价值。Oil well tubing is widely used in the well test,fracture acidizing,water injection,oil production etc.underground work,it is the major force and power transmission components of oil well operation and production.In extended reach well and high angle deviated hole,oil well tubing mechanics behavior research has become one of the key problems to be solved.Based on the geometric description of three dimensional curved hole,a mechanical model of three-dimensional curved hole pipe columns was established by using the principle of minimum potential energy.It provided theoretical basis for analyzing the force status of downhole tubing and tool during fracturing,water injection and testing.The model has higher applied value.
