Development and application of the ultra high temperature high pressure (HTHP) rheometer
Abstract:The national major scientific instrument and equipment development project “Development and industrialization of ultra high temperature and high pressure drilling fluid rheometer” led by Beijing Institute of exploration engineering has lasted for five years, successfully developed super HTHP rheometer 2018 ultra-high temperature and high pressure rheometer, and achieved high precision viscosity measurement under the conditions of high temperature 320℃, low temperature-10℃ and high pressure 220MPa, The main technical indexes have reached the international advanced level, breaking the technical monopoly of foreign high-end drilling fluid rheometer and filling the domestic blank. The product can simulate the real high temperature and high pressure environment. The viscosity of different samples such as drilling fluid, fracturing fluid, gel plugging agent, xanthan gum and so on can be measured in real time according to the changing rules of temperature, pressure and shear rate. It can truly measure the rheological properties of samples under high temperature and high pressure environment, and overcome the disadvantages of the traditional roller furnace hot rolling test sample which leads to the high performance index of the test. Avoid the occurrence of underground accidents.
