FCP mud cake penetrometers, pin is vertically moved down by probe and enters mud cake, is reacted mud cake intensity by pressure sensor, is passed through displacement
Sensor response cake thickness.
The mud cake intensity and thickness testing device of prior art, JHNC mud filter cake testers carry out strength test when,
Current can be damaged to the structure of mud cake, so that the mud cake that can not be continued with by test carries out cementing strength experiment；It is right
In scraper mud cake intensity detecting device and for FCP mud cake penetrometers, although the intensity of mud cake can be reflected to a certain extent,
But two kinds of apparatus structures are complex, and error is easily produced in operating process, it is impossible to accurate directly to reflect the strong of mud cake
Degree and thickness.
