Determination method for optimal installation position of telescopic pipe of deep gas well test pipe column

The invention discloses a method for determining the optimal installation position of a telescopic pipe of a deep gas well test pipe column, and belongs to the technical field of oil and gas exploitation, the method for determining the optimal installation position of the telescopic pipe of the deep gas well test pipe column comprises the following specific steps: firstly, establishing a mechanical model of the deep gas well test pipe column based on the telescopic pipe; then determining a solution scheme of the mechanical model of the deep gas well test tubular column based on the telescopic pipe, performing analog simulation calculation through the obtained mechanical model and the solution method, and finally determining the optimal mounting position of the telescopic pipe of the test tubular column according to the analog simulation calculation result. A theoretical basis can be provided for judging the installation position of the telescopic pipe in oil and gas field well completion test operation; accor
