The utility model provides a kind of radial direction water jet auxiliary fracture simulation device, real for true triaxial hydraulic fracturing thing mould
Test, as shown in Figure 1 to Figure 3, radial direction water jet auxiliary fracture simulation device includes three-dimensional artificial core 1 and triple-travel stress adds
Carry and put 2.
Three-dimensional artificial core 1 includes rock core main body 11, metal vertical tube 12 and metal transverse tube 13, and rock core main body 11 uses cement
Slurry solidification is formed, and metal vertical tube 12 and metal transverse tube 13 are embedded in rock core main body 11, and metal vertical tube 12 is vertically extending
And upper end protrudes rock core main body 11, the lower end closed of metal vertical tube 12, metal vertical tube 12 is used for simulation wellbore hole, metal transverse tube 13 and
Metal vertical tube 12 connects, and metal transverse tube 13 is used to simulate radial direction hoistway；Triple-travel stress loading device 2 includes fracturing experiments frame
21st, three retractor devices 22 and high-pressure pump 23, fracturing experiments frame 21 are used to clamp three-dimensional artificial core 1, three retractor devices
22 are fixed on fracturing experiments frame 21, and three retractor devices 22 are oppositely arranged with three sides of three-dimensional artificial core 1 respectively, are used
In applying rigid load to the three-dimensional corresponding side surface of artificial core 1, high-pressure pump 23 is connected with the upper port of metal vertical tube 12.
The lower end of metal vertical tube 12 is blocked using cement mortar, and rock core main body 11 is using cement, quartz sand, water, water reducer group
Into corresponding mass ratio is 0.5:2.5:0.5:0.004.
Simulation wellbore hole is respectively used to by using metal vertical tube 12 and metal transverse tube 13, for simulating radial direction hoistway, is compared
In traditional four fluorine tube, because four fluorine tube often has certain flexibility, it is difficult to preferable simulation drilling, and the application uses
Metal material particularly stainless steel metal vertical tube 12 and the intensity of metal transverse tube 13 it is big, flexibility is small so that punching 131
When size more preferably control, more standard.Either eyelet i.e. using the metal vertical tube 12 of the application and during metal 13 punching 131 of transverse tube
Size, hole be close or metal vertical tube 12 and metal transverse tube 13 size of itself all compare four fluorine tube more standard, is advantageous to experiment knot
The reasonable contrast of fruit, more standard.And in terms of the result that conventionally employed four fluorine tube carries out fracturing experiments, part four fluorine tube is in cement
It is pressurized in maintenance processes there occurs deformation, it is not cylindrical shape to cause bore hole drilling, directly affects experiment effect, and metal material
Particularly stainless steel material intensity is big, anti-pressure ability is strong for matter, can preferably support cement mortar to form ideal cylindrical radial direction hoistway.
The metal vertical tube 12 and metal transverse tube 13 that the application uses can use machine to punch, and processing is more accurate, can complete diameter
1mm punching 131 and 1mm pitch-row, but the manual operation of four fluorine tube is all difficult to complete, therefore, the metal that the application uses
The small-bore punching 131 that vertical tube 12 and metal transverse tube 13 are presented not only has been more effectively prevented from cement in test specimen process
Slurry intrusion simulation hoistway causes eyelet to block, and Kong Mi increase so that the water penetration enhancing in duct, preferably simulates naked
The characteristic of eye drilling, is advantageous to fracture initiation.And radial direction hoistway is simulated, it is necessary to largely be beaten four fluorine tube using four fluorine tube
Hole, line processing, waste time and energy very much.The pipe processing enterprise of stainless steel punching at present 131 is more, due to standardization system can be achieved
Make, therefore Product processing is more convenient and time-saving, greatly reduces the workload of experimenter.
Retractor device 22 is used to apply rigid load to three sides of three-dimensional artificial core 1.In the present embodiment, stretch
Device 22 can with but be not limited to flat jack, flat jack is controlled by the controller of radial direction water jet auxiliary fracture simulation device.
In other embodiments, can also other can apply the structure of rigid load.
Three flat jacks apply rigid load to three directions of three-dimensional artificial core 1.Three flat jacks are by respectively
Independent triple channel source of stable pressure provides hydraulic pressure, and the pressure size and compression rate of each passage can control respectively.It is sharp in experimentation
Fracturing fluid pressure and other parameters are recorded and controlled with data collecting system, can record and show in real time that pressure etc. is joined during infusion
Number, and the performance graph in energy real-time display fracturing process, can be to test specimen and complete equipment in pressure break mistake according to pressure break curve
State in which judges in journey.Three reversal of stress Loading Control Systems are the Automated condtrols using panel type, are passed through
User inputs the control program of loading procedure, automatic loading, after the completion of experiment, can unload.
Can having with the setting form of metal vertical tube 12 for metal transverse tube 13 is a variety of, for example, as shown in Figs. 4-6, setting 1
Individual metal vertical tube 12 and multiple metal transverse tubes 13.
As shown in fig. 7, metal transverse tube 13 is provided with multiple punchings 131.A diameter of 1mm of the punching 131, it is two neighboring
Punching 131 at intervals of 1mm, while ensureing that radial well has water penetration, ensure that the intensity of metal transverse tube 13 with thick
Dog support cement mortar forms duct, in turn ensure that duct has similar water penetration to bore hole.
It should be noted that cement mortar injects the artificial three-dimensional rock core of Mold Making, while preset simulation wellbore hole (metal vertical tube
12) and simulation radial direction hoistway (metal transverse tube 13), notice needing that speed is slow, dynamics is light during cast, ensure simulation radial direction hoistway as far as possible
Undeformed, position is unchanged.Test specimen is conserved after the completion of pouring.
In the present embodiment, axial directional distribution of multiple punchings 131 along metal transverse tube 13；Or multiple punchings 131 are along metal
The radial direction distribution of transverse tube 13.The external diameter of metal transverse tube 13 is 6-10mm；The wall thickness of metal transverse tube 13 is 1mm.Metal vertical tube
12 external diameter is 3-5cm.
Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every
Under utility model of the present utility model design, the equivalent structure made using the utility model specification and accompanying drawing content is become
Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
