The mud cake performance tester for drilling fluid uses the transmission system to drive the measuring disk to apply pressure to the mud cake at a constant speed. The acquisition system carries out data detection and data collection on the pressure provided by the transmission system, and obtains the measurement results after calculation and processing by the control system. Finally, the data is indicated by color LCD, analysis and archived by computer, then obtain the comprehensive parameters of mud cake performance: mud cake weight, total thickness, actual thickness, virtual thickness, mud cake hardness and toughness.
The instrument is mainly composed of four parts: frame body, transmission system, acquisition system and control system.
The main features are as follows:
1) The actual measuring range is 0-10mm;
2) The resolution is 0.001mm;
3) Measurement accuracy 0.05mm;
4) Repeatability accuracy 0.05mm;
5) It can measure the comprehensive performances of mud cake such as weight, thickness, real thickness, virtual thickness, hardness and toughness;
6)LCD color liquid crystal display, drawing real-time pressure and compression curve;
7) Connect the upper computer, record and print the experimental data through special software;
8) Through the upper computer, the pressure values of final pressure and virtual thick pressure can be set, which improves the flexibility of the instrument.
