Description
Technical field
The present invention relates to fracturing technique apparatus field more particularly to a kind of large scale hot dry rock fractured in-situ experimental provisions.
Background technique
The geothermal energy that hot dry rock is contained in the earth's crust is huge, it has also become the new energy of countries in the world primary study exploitation,
The on-the-ground test research investment of the enhanced geothermal engineering of hot dry rock development of resources is big, the period is long, risk is big, at the scene pressure break and
Before manually heat reservori builds pedagogical engineering, the research of implementation hot dry rock hydraulic fracturing experiments room is necessary, directly existing in order to reduce
The risk investment of field construction just must be set up the enhanced water of hot dry rock of the laboratory room small-sized large scale at simulation scene a set of in this way
It forces and splits simulator, provide parameter and technical support for live fracturing technology design and reservoir reconstruction.
Currently, studies in China hot dry rock fracture initiation and the device of extension are small-scale model research, true triaxial water
Power fracturing device common are two kinds of forms: three axis external hydraulic cylinders, short distance hydraulic cylinder type for now, but at this
There is corresponding drawback using both common loading methods in set system.
Three axis external hydraulic cylinders (volume and weight is excessively huge): external type hydraulic cylinder mode is used to load: with 600mm
On × 600mm × 600mm rock for loading stress 40MPa: needing the thrust on hydraulic cylinder is 1440000kgf, quite.By
50MPa is not exceeded in the load of hydraulic cylinder normal fluid pressure fluid, we are just by taking 50 MPa as an example, when oil hydraulic fluid pressure is
When 50MPa, hydraulic cylinder will generate 1440 tons of power, hydraulic cylinder area are as follows: 500 0.785=3669cm2 of ÷ of 1440000kgf ÷, then
Finding out hydraulic cylinder bore is 61cm, internal diameter 610mm, further according to pressure vessel heavy wall formula calculated wall thickness in 140mm, so liquid
Cylinder pressure outer diameter is in 890mm, since hydraulic cylinder is external, it is necessary to fix plus flange, flange outer diameter is needed in 1140mm
Left and right, thus causes model itself since external type hydraulic cylinder is bulky, causes overall volume too big.
Short distance hydraulic cylinder loaded type (pressure is low): which greatly reduces volume, and practicability is preferable, but loads work
Pressure is low, is not able to satisfy maximum pressure 0-40MPa(600 × 600 × 600mm) requirement.
In addition to this, conventional external true triaxial loading system cannot achieve the load of three axis under high-temperature and high-pressure conditions, by
It is loaded in the loading form using oil cylinder, oil cylinder pushes piston rod under high pressure and applies stress, and single this kind of oil cylinder is in high temperature
Condition not can guarantee corresponding leakproofness, usually fails in the formation temperature conditions lower seal of simulation, leads to two cylinder of oil cylinder AB
Crossfire or piston rod oil leak cannot realize the true triaxial simulation under insitu analog formation condition well.
600 × 600 × 600mm of rock sample specification needed for model not can guarantee the vertical of rock in specification rock sample processing
Degree, inevitably will cause the not upper proper square of rock, and traditional three axis loading mechanism of external applies stress to rock sample
When inevitably will cause oil cylinder inclination, to cause cylinder piston rod plucking or oil cylinder cavity plucking phenomenon；
Conventional square pressure vessel, which calculates, need to use GB150-2011 page 220, and symmetrical rectangle section vessel calculation formula is pressed
Apply stress, while the net 700 × 700mm of inner cavity of model according to 50MPa, stress value 300MPa computation model need to be used by high-strength material
Required thickness is 240mm, while rectangular pressure vessel right angle end stress easy to form is concentrated, and is especially easy under high pressure
Crack is formed from the right angle position.
Equipment need to detect rock fracture trend, be detected using passive acoustic wave, conventional passive acoustic wave is mounted on external load plate
On, then by the load plate to sonic probe and rock core is in close contact, which need to increase 50mm or so in 6 face of rock core and add
Carry transmission plate, while model wall thickness increase about 65mm.
In view of there being above-mentioned problems in the prior art, and with the development of experimental technique, provide a kind of big ruler
Very little hot dry rock fractured in-situ experimental provision.
