Методика прогнозирования долговечности колонны гибких труб на основе результатов лабораторныхи стендовых испытаний

Abstract

Предлагается методика прогнозирования долговечности колонны гибких труб, которая, в отличие от известных, способна отразить полную историю неупругого деформирования и накопления повреждения конкретным объектом, необходимую для его мониторинга. Методика опирается на систему лабораторных и стендовых механических испытаний. Также ее элементами являются разработанные в пакете ANSYS Mechanical специализированные программные модули для расчета кинетики неупругого деформирования фрагмента гибкой трубы в стендовых испытаниях и участка гибкой трубы при выполнении типовой спуско-подъемной операции.

A technique for forecasting the operating life of coil tubing, as opposed to the known methods can reflect a full history of inelastic deformation and accumulation of the damage by a specified object is proposed in the paper. This technique is based on laboratory and bench mechanical tests. Also, authors rely on special software modules developed in the ANSYS Mechanical package for the calculation of kinetics of inelastic deformation of a coil tubing fragment in bench tests and a section of coil tubing when a standard operating procedure is carried out.
