Annotation:

The article notes the need to control the solution viscosity in a well directly during the drilling process and information transmission through the communication channel between the bottom hole and the wellhead. The existing means of measuring the drilling fluid viscosity during the drilling process are considered and their shortcomings are shown. The description of a new device for measuring viscosity in a well is given. The design and operating principle of the drilling fluid viscosity frequency sensor is described. The main functional dependence of the quality factor of a tuning fork on the viscosity of the drilling fluid in the well is presented. An algorithm of a frequency viscosity sensor operation in a well is presented. It is shown that the new method for measuring the viscosity of drilling fluid while drilling a well provides high accuracy.
