Abstract
The invention provides smelting process to prepare physical model of borate glass radix hole container rock. The preparing method use high echo speed borate glass as basal body, the low echo speed as natural galena pore space mock impurity, making the galena to process the micron order particle, firstly melting the borate glass in the high temperature muffle, and then mixing the micron order galena particle in the borate glass basal body when glass is formed. The physical model of borate glass radix hole container rock of this invention, the speed of ultrasonic of basal body is high, the speed of wave of galena pore space mock impurity is low, the wave speed matching good between basal body and pore space wave, the size of model is minor, according with the naturally geology status, making for improving success ratio of proving of container rock,hydrocarbon reservoir etc.
Description
Technical field
The present invention relates to be used for geological research, especially simulate the preparation method of the cranny and cave reservoir physical model of oil gas reservoir matter condition.
Background technology
Hole be in the important space that oil gas preserves, migrates, the especially carbonate reservoir a large amount of holes of growing, solution cavity etc. more oil gas preserve the space condition that provides important.The research bore hole system is to the response of seismic event feature, analyze the relation between hole distribution and growth intensity and the seismic event characteristic attribute parameter, and then the feature of utilizing seismic event understands, is familiar with the distribution and the development degree of bore hole system in the subsurface reservoir, become more and more important research project of geophysicist.The ultrasound wave experiment of physical model by observation and the analysis to artificial physical model, can provide experimental basis as geophysical important research means for the underground opening systematic research.
Ultrasound wave research physical model principle is the rock under the simulation geologic condition and the hole of the inside, model-based n-body simulation n rocky condition normally, and the hole in hole wherein or the doping granule simulation rock.At present generally adopt the low macromolecular material of velocity of wave as matrix both at home and abroad, and select unmatched metal of velocity of wave or air, and physical size is bigger as the hole snotter.According to similarity criterion, the size of model is more little, and the actual geology size of embodiment is big more.Therefore the physical model that exists at present can not accurately reflect the actual conditions of geology, causes the data out of true, and error is bigger.The present invention is that matrix, galenite are the physical model of hole simulation snotter with the borate glass, and the velocity of wave coupling of matrix and snotter is better, and moulded dimension is less, realistic geological condition.
Do not see with the borate glass at present to be that matrix, galenite are patent and the bibliographical information that hole simulation snotter prepares the cranny and cave reservoir physical model.

The preparation method of borate glass base hole reservoir model is characterized in that smelting process, and this method is that matrix, the natural galenite that hangs down velocity of wave are hole simulation snotter with the borate glass of high velocity of wave, and galenite is processed into micron-sized particle.First melting borate glass in the high temperature muffle furnace is mixed in micron order galenite particle in the borate glass matrix when the glass ware forming again, makes borate glass base hole reservoir model.
The preparation method of borate glass base hole reservoir model of the present invention, undertaken by following step:
1. galenite ore reduction, grinding, screening are obtained a series of micron order galenite particles, select the galenite particle of 15 μ m, 30 μ m, 50 μ m, 100 μ m, 150 μ m for use;
2. the crucible that is heated to 1100 ℃ is in advance put in borate glass batch (seeing Table 1) gradation; continuation was warming up to 1200 ℃ of constant temperature 2 hours in muffle furnace; being cooled to 950 ℃ comes out of the stove; cast molding; used grinding tool is at 400 ℃ of constant temperature; to guarantee that glass does not burst, in cast molding, desired particle size galenite particle is mixed in the glass melt.Galenite particle addition is relevant with grain size, is respectively 15 μ m, 10; 30 μ m, 30; 50 μ m, 50; 100 μ m, 70; 150 μ m, 100;
3. after treating that glass ware forming solidifies, the glass-based model that will contain the definite shape of galenite particle places annealing furnace, by 0.5 ℃ of/minute clock rate annealing, takes out to room temperature;
4. the gained sample is carried out sharp processing, the polishing get final product.
