Description
Technical field
The present invention relates to a kind of oil exploration and exploitation field, more particularly to a kind of rock body of casting liquid and preparation method thereof.
Background technology
Rock body of casting liquid is that one kind is liquid in normal temperature, rock body of casting technology（It is also called rock embodiment technology）From the history of more than 50 years has been proposed to development experience, significant progress is obtained at aspects such as theory and technology applications.Its carrier blowhole body of casting instrument is one of widely used basic test equipment in current oil field, it is that rock body of casting liquid is injected into rock sample slit under vacuum, rock body of casting liquid is set fully to enter the fine duct of people's rock, then the device for making rock body of casting liquid polymerizing curable under uniform temperature and pressure under elevated pressure conditions.Rock body of casting sample after processing can be fabricated to casting body flake, body of casting skeleton, the multiple parameters that pore morphology, Areal porosity, pore-size distribution, connection situation, syntagmatic and sky ask the pore structures such as spread can be obtained by technological means such as microscope, ESEM, image analyzers, is that reserves calculating and the formulation of development plan provide basic data.
Traditional rock body of casting liquid is mainly by coloring matters such as the epoxy resin or organic hyaline monomer and Wood's metal of staining reagent.However, traditional rock body of casting liquid is in uniform temperature and by after solidification equipment solidification, its consolidation not enough fully, mainly due to there is more particulate powder or impurity in its liquid.Consolidation not enough fully its coloured portions can then seem more fuzzy, make researcher directly by observing the distribution of pores of rock sample in rock sample thin slice the various parameters of follow-up study cannot be caused not accurate enough.
The content of the invention
In view of the shortcomings of the prior art, solidify afterwards structure is solidified fully by uniform temperature and solidification equipment the invention provides one kind, the color clear in rock sample makes researcher intuitively to implement rock body of casting liquid of observational study and preparation method thereof to rock sample hole.
To achieve the above object, the invention provides following technical scheme：A kind of rock body of casting liquid, it is characterised in that：Include azodiisobutyronitrile 1.4g -1.5g, methyl methacrylate 450ml -500ml and oil blue N or oil red O2.5g -2.8g.
Using above-mentioned technology case, implement to mix with methyl methacrylate using the azodiisobutyronitrile of said ratio, its solution is by after heating and solidification, its consolidated structures is abundant, be not in sticky situation, be easy to the follow-up research to injecting the rock sample of the rock body of casting liquid, using oil blue N or oil red O as coloring agent, it is sufficiently mixed rear its color clear with azodiisobutyronitrile and methyl methacrylate, and researcher can intuitively observe position and distribution in the rock body of casting in rock sample.
The invention provides rock body of casting liquid and preparation method thereof in a kind of claim 1, it is characterised in that：Step is as follows：
A, azodiisobutyronitrile is poured into methyl methacrylate, azodiisobutyronitrile produces foamable reaction with methyl methacrylate, and be blended with azodiisobutyronitrile methyl methacrylate solution implement fully rock, untill in solution without powder remnants, azodiisobutyronitrile is set to be completely dissolved in methyl methacrylate；
B, oil blue N or oil red are poured into step a by the solution for fully rocking mixing and implementation is fully rocked, in the solution in making oil blue N or oil red be dissolved completely in step a, rocking untill remaining without powder.
Using above-mentioned technical proposal, azodiisobutyronitrile from quantitative proportioning pours into implementation mixing in methyl methacrylate, need sufficiently to rock in the process, it is rocked into degree and can be observed by operator implements, without more than powdered ginseng in the solution that i.e. azodiisobutyronitrile mixes with methyl methacrylate, it is guaranteed by its consolidated structures after heating and solidification, oil blue N is consistent with the above with the mixed process of oil red O, all rock to remaining without powder ginseng, consolidated structures is further ensured.And coloring agent selects oil blue N or oil red O, it is sufficiently mixed rear its color clear with azodiisobutyronitrile and methyl methacrylate, and researcher can intuitively observe position and distribution in the rock body of casting in rock sample.
The invention will be further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the rock sample thin slice made using the conventional rock body of casting；
Fig. 2 is the rock sample thin slice made using the rock body of casting in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention be it is a kind of can be by the rock body of casting liquid after heating and solidification as the rock body of casting in rock sample, after the rock body of casting liquid is injected into the hole of rock sample, by heating and solidifying, its consolidated structures stablizes compact, and color clear, researcher can intuitively observe position and distribution in the rock body of casting in rock sample, be easy to observation and research of the researcher to the rock sample, make the data to rock sample research more accurate and stable.
Rock body of casting liquid is made up of azodiisobutyronitrile, methyl methacrylate and oil blue N or oil red in the embodiment of the present invention, wherein azodiisobutyronitrile is the foaming agent without the oil-soluble azo initiator of side reaction first order reaction, and methyl methacrylate is lucite polymethyl methacrylate（PMMA）A kind of organic compound of monomer.Oil blue N is purple to black powder（C24H30N2O2）, oil red O is black powder（C26H24N4O）.Wherein, azodiisobutyronitrile 1.4g -1.5g；Methyl methacrylate 450ml -500ml；Oil blue N or oil red O2.5g -2.8g.
Its preparation process is as follows：The azodiisobutyronitrile of a, preferably 1.5g is poured into the methyl methacrylate of 500ml, azodiisobutyronitrile produces foamable reaction with methyl methacrylate, and be blended with azodiisobutyronitrile methyl methacrylate solution implement fully rock, it is rocked into degree and can be observed by operator implements, without more than powdered ginseng in the solution that i.e. azodiisobutyronitrile mixes with methyl methacrylate, azodiisobutyronitrile is set to be completely dissolved in methyl methacrylate；The oil blue N or oil red of b, preferably 2.78g are poured into step a by the solution for fully rocking mixing and implementation is fully rocked, in the solution in making oil blue N or oil red be dissolved completely in step a, rocking untill remaining without powder.
It is specifically more abundant with ratio and mixed process because being selected in preparation process, make the rock body of casting liquid in the embodiment of the present invention more compact and stable by the consolidated structures after heating and solidification, from oil blue N or oil red as coloring agent, make the rock body of casting be distributed in rock sample hole color it is more distinct and directly perceived.
Can clearly know that consolidation structure is more long in accompanying drawing 1 with the contrast of accompanying drawing 2 by accompanying drawing 1, surface has sticky oil reservoir, and the consolidated structures of the rock body of casting being made using the formula of the embodiment of the present invention are compact and solidification is abundant.
