Simulation test system for temperature resistance and pressure resistance of packer rubber sleeve

Abstract

The invention discloses a simulation test system for the temperature resistance and the pressure resistance of a packer rubber sleeve. The simulation test system comprises a sleeve induction heating device, a middle-frequency power supply and control system, a pressurizing device and a computer monitoring system. The sleeve induction heating device comprises a surface sleeve, a heating sleeve arranged in the surface sleeve and an induction heating mechanism arranged on the surface of the heating sleeve, wherein heating sleeve is connected with the pressurizing device, and the induction heating mechanism is connected with a middle frequency power supply and control system. The middle frequency power supply and control system and the pressurizing device are both connected with the computer monitoring system. A pressurizing and heating experiment for an underground tool to be tested is finished in the heating sleeve. The simulation test system uses a middle frequency induction heating method, an induction heating coil is wound on the heating sleeve, the heating speed is quick, and accordingly the testing efficiency is improved. The simulation test system is simple in equipment structure, small in disposable equipment investment, low in operation management cost and good in safety and environmental friendliness.

Description
