| Abstract: | Expandable liner hanger is an emerging liner hanger developed on the basis of expandable tubular technology, which can compensate the disadvantages of conventional liner hanger and reduce the cost. This paper introduces the principle of expandable liner hanger and analyzes the working mechanism of metal rings in liner hanger by indoor experiment. The suspension force provided by metal rings with different structure parameters is simulated based on ansys ls-dyna nonlinear finite element software. The conclusion is proposed through comparing data obtained from indoor experiment and simulation. |
