Background technology
With a large amount of exploitations that domestic and international unconventionaloil pool is hidden, increasing hypotonic, fine and close oil-gas reservoir is difficult to routine
Mode is exploited, therefore the research and development that unconventionaloil pool hides new technique both at home and abroad are current Petroleum Engineer focuses of interest.Closely
Decades hydraulic fracturing technology for unconventionaloil pool hide, particularly for shale and tight gas reservoir exploitation at home and abroad quietly
Rise.The successful Application of hydraulic fracturing technology, it is ensured that the effective exploitation that unconventionaloil pool is hidden.Meanwhile, the general layout of world's oil gas
Also new chapter has been opened.Now, the volume fracturing technology in hydraulic fracturing technology system is opened for hypotonic, fine and close oil-gas reservoir
The advantageous methods sent out.The principle of volume fracturing technology mainly first by prepad fluid formed major fracture and multistage secondary fracture or
Major fracture links up the fracture network promise to form complexity with natural secondary crack.Secondly, complicated crack is entered by pumping into load fluid
Net promise is supported.Effective support of the proppant in complicated fracture network promise, can be that the seepage flow of oil gas improves higher leading
Stream ability, so that unconventional fine and close oil-gas reservoir obtains higher yield.But, formation fracture complex shape, the limitation of technology,
The form in crack is difficult to predict in advance, therefore field engineer can only pass through business software or experience judges whether proppant enters
The fracture network promise of complexity is entered.However, the model of business software is more single, experience also lacks scientific theory support.For
Effective laid research of the support agent in seam net seems particularly critical.
The effectively laid in seam net of proppant is concentrated mainly on Physical Experiment and numerical simulation is studied.Forefathers'
Physical Experiment research of the proppant in monolete has been occurred in that on Research foundation.Such as：A kind of hydraulic fracturing proppants sedimentation
And permeability test device (application number 201310023290.7), in seam, liquid takes sand analogue experiment installation (application number
201220133225.0) settle and laid experimental provision (application number with a kind of agent of simulation fracturing fracture inner support：
201420093980.X) etc..Physical Experiment research of the proppant in stitch simultaneously is also current focus more.Such as：East China oil
A kind of simulation volume fracturing complexity of university is stitched the device of net proppant settlement law and its applies (application number：
201410325825.0) a kind of, simulation multi-angle seam net proppant settlement law device (application of Southwest Petrol University's application
Number：201520137784.2) etc..Existing physics facility is all in the experiment for carrying out in fixed seam width.Large scale is variable
The wide varied angle of seam stitches the laid device of net proppant at home and abroad or blank out.However, in real stratum major fracture with it is secondary
It is change in the horizontal that raw width is, and the width in crack has a great impact for the laid effect of proppant, directly
Connecing affects the effect of later stage flow conductivity.Therefore, in the laid device of large scale varied angle seam net proppant of existing autonomous Design
On the basis of, change design structure completely so that it is all change (wedge shape in the horizontal that the seam of major fracture and secondary fracture is wide
Seam) so that model is more close to live real fracture pattern, meanwhile, the device is served newly to the physical study of experiment
Theory support.
