The fixture of rock sample is whole to be rotated at random 360 degree along pedestal, and the one of control moving jaw of three movable control handles is big
Small, other two can control jaw and all around moves with fixture rock sample.Fixture is a square (10 centimetres of side length)
The copper billet of one cylinder of middle cut away (10 centimetres of 5 cm height of diameter), it is that be split into two halves from centre can be removable by four
Long screw is locked together.The fixture for clamping rock sample is placed in cross swivel vice moving jaw and is placed on experimental machine
On, it is allowed to keep one layer of liquid film by titrating any drilling fluid on rock sample end face, when can be with real-time testing difference aquation
Between any point dynamic change intensity on rock sample end face.
The advantages of the utility model: the variation of real-time testing shale hydration dynamic changes of strength, convenient test is quick, dismounting letter
It is single, it can be reduced using rock sample quantity and experimental period, it is cheap.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of shale hydration dynamic changes of strength variation test new equipment of the utility model, mainly by scheming
3 fixtures and Fig. 4 cross swivel vice composition.Wherein fixture Fig. 3 is mainly by 10 centimetres of side length of square copper billet 10 from centre
The cylinder composition of 10 centimetres of 5 cm height of diameter is cut away, wherein Fig. 3 fixture is split into two halves from centre, by 5 centimetres of height of diameter
Spend 10 centimetres of circumference side waxdips rock sample column put into fixture after use four root long screws 11 locked be assembled into one it is whole
Body need to only expose the upper surface of rock sample, guarantee after long screw locking drilling fluid of the drop on rock sample end face will not seepage flow to rock sample
Side and impregnate.The fixture 3 for installing rock sample is put into the moving jaw 13 on Fig. 4 cross swivel vice, adjustable clamp is passed through
Mouth controls handle 12 for clamp.Moved cross beam 5 is gone up and down by the hydraulic pump 7 that control figure 1 tests 8 the inside of machine base rotating
It is moved on axis 6, sample stage 4 is elevated to the suitable distance between pressing mold 2, wherein the position of pressing mold 2 is to be fixed on load position
It is immovable on displacement sensor 1.The fixture overall diagram 2 that cross swivel vice clamps rock sample is being put into experimental machine Fig. 1 again
Sample stage 4 on.Preceding dropper is tested in experiment and titrates one layer of drilling well liquid film on rock sample end face, to drilling fluid aquation rock sample one
After the section time, 9 opening operation software of computer is opened, moved cross beam 5 is gone up and down by control hydraulic pump 7 and is moved in rotary shaft 6
When rock sample has contacted pressure with pressing mold 2, pressing mold 2 is pressed into the displacement and corresponding load of rock sample by loaded displacement pickup 1
It is transmitted on computer function recording instrument 9.It can be led to when one on complete rock sample end face to be tested according to aquation different time
It crosses before and after the jaw left and right moving control handle 15 on 4 cross swivel vice of control figure, 360 degree rotation dial 16, jaw
Movement control handle 18 will select a little mobile of the rock sample end face of test or rotate to below pressing mold 2 to be tested.
The result of test point after different hydration times is finally shown that the indentation of rock sample is strong by 9 finishing analysis of computer function recording instrument
Degree, to analyze the influence degree that drilling fluid changes rock sample aquation dynamic changes of strength, finally evaluates borehole wall stability.
As shown in Figure 1 and Figure 2, it is the test result of rock sample dynamic change after preferably evaluation aquation, passes through Fig. 3 and make folder by oneself
Tool and the innovation of Fig. 4 cross swivel vice, which combine to be placed in Fig. 1 experimental machine to test, obtains different aquations on rock sample end face
The intensity of time difference position.The position of pressing mold 2 is irremovable when due to experiment test, fixture in Fig. 2 and
The innovation of cross swivel vice is combined instead of the rock sample being placed on after being impregnated merely on Fig. 1 experimental machine sample stage 4 in the past.With
It is the rock sample column of 5 centimetres of 2.5 cm height of diameter used in preceding experiment, Fig. 1 experiment can only be fixed on after by mud soak
It is equivalent in Fig. 13 position in press proof sample platform 4, a point of rock sample can only be tested after contacting with pressing mold 2, due to rock sample end face
Diameter is smaller, and being completed rear rock sample crushing rupture cannot continue to test, when continuing test immersion aquation difference if necessary
Between intensity can only bore sample again column, then the subsequent continuous test of aquation is impregnated, so the shale hydration of this utility model of Fig. 2
Dynamic changes of strength variation test new equipment greatly facilitates experiment test, shortens experimental period, saves experimental cost.
