The principal of improvement of experimental installation for viscous-plastic oils and suspensions structural-mechanical properties definition is stated and the results of researches carried out via this installations are provided. It was established that conditions for test quantity increase is created in two capillary viscometers. The method for accurate account of hydrostatic pressure in capillary tube input, created via liquid column in working camera is offered. The rules of definition of viscous-plastic oils structural-mechanical properties in formation conditions have been also reviewed.
