A high-temperature, high-pressure corrosion resistance reaction experimental device and a method for using the reaction kettle system thereon

Abstract

The invention discloses an experimental device for high temperature and high pressure anti-corrosion reaction, and belongs to the technical field of high temperature and high pressure anti-corrosion reaction. An existing high temperature and high pressure reaction kettle has the defects that a kettle body is heavy, is difficult to detach and is insufficiently sealed, the temperature and the pressure are unlikely to control, and the on-line sampling cannot be realized. The experimental device for the high temperature and high pressure anti-corrosion reaction comprises an air supply system, a piston container, a reaction kettle system and a control system. Various materials can generate chemical reaction in the experiment device in a high temperature and high pressure range of 50MPa pressure and 350 DEG C temperature; components, such as a piston, a cylinder body, an end cap, the reaction kettle body and a sampler, directly in contact with a reaction solution are made from a hastelloy material so as to have the strong corrosion resistance. The experimental device has functions of temperature and pressure presetting, and temperature and pressure overload protection; meanwhile, the experimental device is provided with electromagnetic propelled stirring blades which can be used for stirring reactors during reaction, so that the reaction speed is increased; furthermore, the experimental device is provided with the sampler so as to realize the on-line sampling on the reaction solution.

Description

technical field [0001] The invention belongs to the technical field of high-temperature and high-pressure corrosion-resistant reactions, and in particular relates to a high-temperature and high-pressure corrosion-resistant reaction experimental device for simulating the generation and dissolution reaction of organic acids under geological conditions. Background technique [0002] The successful exploration and development of tight oil in North America has led to an upsurge in unconventional oil and gas exploration. Tight oil has become a new field of global unconventional oil and gas exploration and development, and the secondary pores formed by the dissolution of organic acids on tight oil reservoirs are the main storage space for tight oil. Existing studies on the dissolution of tight reservoirs are mainly focused on tight sandstones but are not related to the formation of organic acids. Therefore, the research on the formation and dissolution of organic acids is of great ...
