1. slider testing method

1) The specification is carefully read. And checking whether the connection of each connection part is firm and reliable. The power supply is reliably grounded.

2) When the power is switched on, the display screen 31 displays the information. Pressing the running key to check whether the running of each rotating part is normal. If normal, the workbench 40 without the groove surface is turned upwards, and two clear keys are pressed to clear the numerical value for standby.

3) The leveling handle 11 is adjusted to the left and right, the horizontal bubble 42 is observed, the worktable 40 is adjusted to be horizontal without the groove surface, and the preparation work is finished.

4) The resulting mudcake after fluid loss as per API standard is placed on a flat surface without grooves on the table 40.

5) The slide was gently placed on the cake and allowed to stand for one minute.

6) When the running key is pressed down, the speed reduction motor 32 drives the output rotating shaft 33, so that the workbench 40 drives the sliding block to slowly turn over. While the numbers on the display screen 31 also slowly increase from zero as the table is flipped.

7) When the slide block starts to slide along with the overturning of the workbench 40, the stop key is pressed, and the angle value and the tg value on the display screen 31 are read, wherein the tg value is the friction coefficient of the mud cake.

2. Slide bar test method

1) The slider test methods 1 and 2 were repeated. After confirming that all items are normal, the surface with the groove of the workbench 40 is turned to the upper surface, and the two-down zero clearing key is pressed to clear the numerical value for standby.

2) And (4) adjusting the leveling handle 11 leftwards and rightwards, observing the horizontal bubble 42, leveling the grooved surface of the workbench 40, and finishing the preparation work.

3) The mud cake obtained after filtration according to the API standard is placed in a groove of the workbench 40, and a part of the same drilling fluid is placed on the mud cake. The slide bar is then gently placed on the drilling fluid in the recess. And standing for one minute.

4) When the running key is pressed down, the speed reduction motor 32 drives the output rotating shaft 33, so that the workbench 40 drives the slide bar to slowly turn over. And the number on the angle display screen 31 also increases slowly from zero as the table 40 is flipped.

5) And when the slide bar starts to slide along with the overturning of the workbench, pressing a stop key, and reading the angle value and the tg value on the display screen. the tg value is the coefficient of friction of the mudcake.

6) The test requires a plurality of mud cakes of the drilling fluid, and the slide bars of the mud cakes are different in standing time, wherein the standing time can be selected from 1, 3, 5, 7, 9, 11 and 13 \8230;, and the minutes are selected. The slide bar is kept still for a certain time. Until the friction coefficient does not increase any more at the following points, it can be seen that the curve rises to a certain extent by plotting a graph of the measured angle and the standing time. The state is smooth, and the inflection point value is the maximum friction coefficient and the static pressure time. And then, directly making the drilling fluid of the same type for the maximum standing time.
