The seismic physical model material and system of a kind of titanic oxide nano modified epoxy Preparation Method
Technical field
The present invention relates to earthquake model field, furtherly, it is related to a kind of titanic oxide nano modified epoxy Seismic physical model material and preparation method.
Background technology
With going deep into that oil exploration works, difficulties in exploration is also increasing, many geological phenomenons and wave field communication theory Needs obtain further checking with it is perfect, exploitation method also needs further development, and physical model analogue technique is earth thing One of key technology of research is managed, is important " assistant " for being engaged in theoretical question research.
Seismic physical modeling technology is in the lab, signal to be excited and received by ultrasonic transducer, so as to utilize Ultrasonic wave simulation field seismic wave, obtains earthquake simulation data volume, in the lab by seismic physical model, discloses seismic wave Propagation law in complicated structure.Cast material analogue technique is the basis of forward physical model simulation, domestic at present major Institutes and colleges and universities mainly with the method for asphalt mixtures modified by epoxy resin moulding by casting, according to high speed stratum needs, prepare velocity of wave 2600m/s's Material, but epoxide resin material has the following disadvantages:
During one is existing formula, epoxy curing agent typically uses 650 types, because 650 type curing agent activity are low, solidification Speed is slow, so in model casting process, hardening time is more long, the serious efficiency that have impact on molding.
During two are existing formula, the model highest velocity of wave prepared reaches 2600m/s, it is impossible to enough simulate the need of actual formation Ask, it is unfavorable to making complicated structure model.
The content of the invention
To solve problems of the prior art, the invention provides a kind of titanic oxide nano modified epoxy Seismic physical model material and preparation method.Hardening time is shortened, the effect for preparing seismic physical model is effectively raised Rate, and new material has penetrability higher, effectively raises acoustic wave propagation velocity, is the system of seismic physical large-sized model Lay a good foundation.
An object of the present invention there is provided a kind of seismic physical model of titanic oxide nano modified epoxy Material.
Including the following components for solidifying:
The weight portion of epoxy resin 100
650 type curing agent 80-100 weight portions
Titanic oxide nano 1-10 weight portions, preferably 5-6 weight portions.
Epoxy resin is preferably epoxy resin of the viscosity in 11000-14000mPas scopes, more preferably E-51 types asphalt mixtures modified by epoxy resin Fat.
650 type curing agent molecular weight 1000~1500, light yellow glutinous thick liquid, density (75 DEG C) 0.92~0.96g/ cm³Amine value 230~260mg KOH/g, (75 DEG C of viscosity)3000~1000mPas.Versamid composition is more multiple It is miscellaneous, containing primary amine, secondary amine and amide groups, can cured epoxy resin at room temperature.
The particle size range of titanic oxide nano is 5-25nm.
Seismic physical model experiment is according to 1 in laboratory by the geological structure and geologic body in field:10000 equal proportions Diminution is fabricated to geological model, and carries out forward simulation to field method of seismic prospecting with methods such as ultrasonic wave or laser ultrasonics A kind of earthquake simulation method,
By special seismic physical model Preparation equipment and the seismic physical model material of preparation technology synthesizing new, utilize Similarity principle builds seismic physical model, and actual physical model is approached by setting up to compare, and explores and understanding complicated structure And in fracture cave reservoir seismic wave propagation law, for oil-gas exploration and development provides favourable foundation, while being physics mould from now on The making of type is laid a good foundation.
The investment of seismic physical model experimental study is small, and compared with Mathematical Modeling, its biggest advantage is exactly seismic physical mould The authenticity of type analog result, is not limited by computational methods, assumed condition, thus seismic physical model is subject to domestic and international each stone Oily company and the great attention of university.Application of the seismic physical model experiment in oil and gas exploration, exploitation is more and more wider It is general.It is natural in the oil such as theory of earthquake wave research and complicated structure, slit band detection, crosshole seismic research and deposit dynamic monitoring Played an important role in gas exploration, development.
After pure epoxy resin solidification, the acoustic wave propagation velocity of material is 2600m/s, is adulterated by titanic oxide nano and changed Property epoxy resin, be the effective ways for improving epoxide resin material velocity of wave, and because 650 type curing agent activity are relatively low, solidification Speed is slow, so in model casting process, hardening time is more long, the serious efficiency that have impact on molding.By titanium dioxide Nano powder doping vario-property epoxy resin seismic physical model, hardening time shortens, and the SVEL of material is increased substantially, It is the ideal material of seismic physical model preparation, the present invention is first titanic oxide nano materials application to seismic physical model Material Field, titanic oxide nano can uniformly disperse in the epoxy, will not produce the phenomenon of reunion, use 650 type curing agent, participate in the chemical reaction of doping vario-property material, and the material prepared has good penetrability.Due to choosing Titanic oxide nano is taken, after doping ratio reaches 5% to titanic oxide nano in the epoxy, i.e. epoxy resin, material Speed reach maximum 2857m/s, after continuing to increase the doping ratio of titanic oxide nano, the speed of material drops on the contrary It is low.
The second object of the present invention is to provide a kind of seismic physical model material of titanic oxide nano modified epoxy The preparation method of material.
Including:The component is by prepared described seismic physical model material after consumption solidification.
Curing can use the common curing in this area, preferably carry out according to the following steps in the present invention:
1. pretreatment
According to the demand of model materials, a certain amount of epoxy resin E51 is placed in 50 DEG C of 1 hours of preheating of baking oven, then Taking-up vacuumize 30 minutes it is standby.
2. mould pretreatment
After mould is made, one layer of release materials are applied in mould inner surface, it is general to use silicon rubber as release coating, Deng casting mold again after silicon rubber glue fixed.
3. material configuration
Material is weighed by recipe requirements after processing, first carry out uniformly 650 type curing agent and titanic oxide nano Stirring, then addition epoxy resin makes it stir wherein.
4. cast model is vacuumized
After material is prepared and stirred, vacuumize process 10 minutes is subsequently poured into packaged mould, when its solidification It is collapsible die after completely.
The present invention is different by changing titanic oxide nano ratio shared in the epoxy, is received by titanium dioxide Specimen acoustic wave spread speed prepared by ground rice doping vario-property epoxy resin increases than pure epoxy resin, acoustic wave propagation velocity point Not Wei 2557m/s-2857m/s seismic physical model material.
The effect of invention
1. the new material SVEL after titanic oxide nano doping vario-property increases, and highest velocity of wave reaches 2857m/s.
2. the new material after titanic oxide nano doping vario-property has good penetrability, and highest can reach 420mv。
3. the new material hardening time shortening after titanic oxide nano doping vario-property, effective to improve seismic physical mould Type prepares speed.
