2results about How to "Accurate data collection" patented technology

This utility model discloses a digital dial indicator and deflection meter, relating to the field of road surface testing technology. It includes: a main housing; a measuring rod installed in the main housing; a first detection element connected to the measuring rod, used to detect the deformation of the measuring rod during measurement; a controller fixed inside the main housing, with the detection element connected to the controller; the controller receives and stores the detection data acquired by the detection element; a display screen fixed to the outer surface of the main housing, connected to the controller, used to display the detection data; and a wireless transceiver unit connected to the controller, used to receive signals for remote control of the dial indicator. By setting the controller to collect and store data, manual data recording is eliminated, improving work efficiency; and by setting the wireless transceiver unit, the dial indicator can be remotely controlled.

This invention belongs to the field of mechanical technology for drilling engineering circulation systems, specifically relating to a device and method for measuring the distribution of cuttings within a wellbore. The invention includes a hose support, a simulated wellbore unit, an inclination adjustment device, a drilling fluid tank, a power circulation mechanism, a stirring motor, and a control terminal. By calibrating the device for measuring the distribution of cuttings within the wellbore, this invention verifies the consistency and repeatability of its channels, ensuring the accuracy of system data acquisition. The device in this invention is a closed system, producing no pollution and no harmful emissions. This invention automatically measures the distribution and movement of cuttings in the annular space under conditions where visible light cannot penetrate, and can simultaneously measure the cuttings removal rate and the impact force of fluid flow on the wellbore. This invention can clearly define the distribution and flow state of cuttings in the annular space, allowing for adjustments to the drilling fluid formulation and performance, improving the efficiency of cuttings removal within the wellbore, and reducing drilling fluid costs.
