Problems solved by technology

The disadvantage of this method is that high-temperature firing will affect the properties of the rock sample skeleton. The mechanism of this effect is complex, and will eventually reduce the accuracy of the rock sample physical parameters.
[0008] In the past physical model technology of fractured reservoirs, metal flakes or polymer flakes were embedded in the artificial sandstone medium, and then the flakes were removed by acid solution dissolution or high-temperature baking and gasification to generate fractures. However, acid solution dissolution and high temperature Baking will have a certain impact on the physical parameters of the sandstone skeleton, resulting in instability

Embodiment 1

[0053] Preheat the epoxy resin in a 50°C incubator for 2 hours, and place the 593 curing agent in a 30°C incubator for 1 hour;

[0054] Mold pretreatment:

[0055] Apply silicone rubber on the inner wall of the mold, and complete the mold pretreatment after the silicone rubber is cured. The inner cavity length of the mold is 300mm, the inner cavity width is 150mm, and the inner cavity depth is 100mm.

[0056] Take 1000 parts by weight of quartz sand, 70 parts by weight of epoxy resin, 10 parts by weight of 593 type curing agent and 3 parts by weight of polyvinyl alcohol film. First cut the polyvinyl alcohol film into slit-shaped strips with a length of 10 mm and a width of 1 mm, and divide them into 19 equal parts. Then mix the epoxy resin and curing agent evenly, add them into the quartz sand, mix evenly again, and divide the mixed raw materials into 20 equal parts.

[0057] Put 1 part of the quartz sand mixed raw material into the mold, flatten it with a pressure head, an...

Embodiment 2-7

[0062] Each step of embodiment 2-7 is identical with embodiment 1, and difference only is that the consumption of epoxy resin, solidifying agent, water-soluble macromolecular material is different, and the specific consumption of each material and test result in embodiment 2-7 are shown in Table 1, Epoxy resin, curing agent and quartz sand are all expressed in parts by weight. The wave speed X represents the longitudinal wave speed in the X direction of the model, and the unit is m / s.

[0063] See Table 1 for specific ratios.

Abstract

The invention discloses material for a fractured reservoir earthquake physical model. The material comprises quartz sand, epoxy resin, a curing agent and a water-soluble polymer film. The invention further discloses a manufacturing method of the fracture type reservoir earthquake physical model and the prepared fracture type reservoir earthquake physical model. According to the invention, the fractured reservoir earthquake physical model is constructed by embedding the water-soluble polymer material into artificial sandstones. The proportions of the water-soluble polymer material in the mixedmaterial are different; the fracture type reservoir earthquake physical model with the sound wave propagation speed difference range between 100 m/s and 500 m/s in each direction can be prepared. Compared with a conventional fracture type earthquake physical model, the invention improves the defects in a conventional fracture type earthquake physical model technology, can obtain an earthquake physical model with higher stability and similarity, and can obtain more accurate experiment data.

Description

technical field [0001] The present invention relates to the technical field of seismic physical models for oil and gas exploration geophysics, and more specifically, to a fractured reservoir seismic physical model material, a method for making a fractured reservoir seismic physical model, and a physical model. Background technique [0002] The basic principle of seismic physical simulation is to use corresponding materials in the laboratory to miniaturize the actual stratum structure or various types of oil and gas reservoirs into physical models under the principle of proportionality factors, and use ultrasonic testing methods to compare field seismic exploration methods. A forward simulation of data acquisition. In the process of earthquake physical simulation, in order to keep the kinematic characteristics of the simulation results consistent with the kinematic characteristics of seismic waves in the actual geological structure and geological body, it is necessary to make...
