High-Temperature and High-Pressure Test Rig for Downhole Tools
- It’s a specialized system designed to evaluate the performance, reliability, and safety of downhole tools under conditions that closely replicate those encountered in oil and gas wells. These tools—including drilling assemblies, completion equipment, retrievable safety valve, dissolvable frac plug, gas lift valves, and measurement-while-drilling components—must operate reliably in extreme environments where elevated temperature, high pressure, vibration, and corrosive fluids are present.

Overview
It is a specialized simulation testing equipment adapted to the working conditions of deep and ultra-deep oil and gas wells. It complies with API 11D1, API 14A and SY/T industry standards, and is mainly used for ex-factory quality inspection, type test and re-inspection in service for various downhole tools such as packers, frac plugs and downhole PSV. The equipment can accurately simulate composite working conditions such as downhole high temperature, high pressure, axial load and medium immersion to effectively test the structural strength, sealing performance, action stability and fatigue resistance of downhole tools, and accurately eliminate various hidden dangers in downhole operations. Through real working condition simulation tests, it can effectively verify the downhole adaptation performance of the tools to provide reliable test data support for product quality acceptance, working condition adaptation type selection and on-site safe construction, which is an indispensable core testing equipment in the field of oil and gas drilling and completion.
