DEVICE FOR QUASI-CONTINUOUS DENSITY AND VISCOSITY MEASUREMENT

摘要

The invention relates to a device for the quasi-continuous measurement of the density and viscosity of a drilling fluid while drilling a bore hole. According to the invention, the device consists of a vertical tube (), open at a lower end, which is immersed into a drilling fluid () and which is in connection with a hose (), at its upper part, the tube () being provided with two lower and upper joints () connected, by means of some lower and upper pipes (), to a differential manometer (), where inside the hose () there may be achieved a pressure higher or lower than the atmospheric pressure, which provides the lowering or lifting of the level of the drilling fluid () from/into the vertical tube ().
