Technical Field

The invention relates to the technical field of drilling instruments, in particular to a drilling fluid parameter measuring device and a control method of the measuring device.

Background

Drilling fluids are fluids used in drilling, which have the following functions: and (I) washing the bottom of the well, suspending and carrying the debris and keeping the well clean. And (II) balancing the pressure of the stratum, stabilizing the well wall and preventing well collapse, blowout and lost circulation. And (III) transferring water power to assist the drill bit in breaking rock. And (IV) transmitting power for the underground power drilling tool, and (V) cooling the drill bit and the drilling tool. And (VI) performing geological and gas logging by using the drilling fluid. The conventional properties of the drilling fluid, such as the density and viscosity of the drilling fluid, have a great influence on the drilling operation. The viscosity concept of the drilling fluid is as follows: the viscosity of the drilling fluid is the total reflection of the internal friction between solid particles, between solid particles and liquid molecules, and between liquid molecules when the drilling fluid flows.

The density and viscosity of the drilling mud are measured in a drilling site, and the density and viscosity are mainly measured by a site operator through a mud densitometer and a Ma-Sampson-funnel viscometer respectively. The mud hydrometer obtains the density of the mud by moving a weight in a balance mode; the mahalanobis funnel viscometer measures manually the time a fixed volume of slurry is flowing from the funnel by means of a stopwatch as the slurry viscosity value. Both of these two methods require manual operation and metering by mouth operating personnel. The operation is responsible, and the measurement accuracy is low.

Based on the technical problems, the application provides a technical scheme for solving the technical problems.
