The Problem of Drilling Mud Parameters Continuous Monitoring and Its Solution at the Example of Automatic Measurement of Its Density

Optimization of technological parameters of airlift operation when drilling water wells

“…When drilling with reverse circulation of the drilling fluid, this problem is even more relevant, since when the compressor performance changes, the density of the drilling fluid also changes. In [18], a device was proposed for automatic measurement of drilling fluid density and cuttings content in it. Automatic density monitoring can significantly improve the efficiency of suction assisted drilling and reduce the cost of dealing with complica tions and accidents.…”

Automatic density monitoring can significantly improve the efficiency of suction assisted drilling and reduce the cost of dealing with complica tions and accidents.Since the fluid always moves from a position where it is under some pressure to a position where the pressure is lower, the considered difference in hydrostatic pressures is the reason for the upward flow of drilling fluid inside the drill string.The difference in hydrostatic pressure is used to overcome the fluid friction of the mixture against the inner walls of the drill string.…”
