Embodiment Construction

[0022] Next, a specific embodiment of the present invention will be introduced. The scope of protection of the present invention is based on the claims, and is not limited by this embodiment.

[0023] First, laser print two sets of numbers including each rock sample on coated paper (since the laser printer uses toner, it will not be dissolved by oil). In order to facilitate cutting, it is advisable that the upper, lower, left, and right intervals of each sample number on the coated paper can be about 2.8cm when printing. Place two sheets of coated paper with the same sample number printed on top of each other in the same direction, that is, the side printed with the number is facing up. Then apply the release agent silicone grease evenly on the lower piece of paper, and press the two pieces of paper tightly to make them stick firmly. Then the sample number is punched out with a regular octagonal mold, the diameter of the circumscribed circle of the mold is about 2.9 cm, fina...

Abstract

The invention is a method for fabricating rock gap casting sheet, which comprises: superposedly arranging two regular polygon copper papers printed with identical rock sample numbers between each two rock samples as spacing material; uniformly painting release agent between two regular polygon copper papers, and compacting the two copper papers. The testing sample is guaranteed to be labeled unique identification in the process of fabricating a plurality of rock sample castings, thereby guaranteeing one-to-one correspondence of sample numbers in the sample separating process, and greatly improving efficiency of fabricating castings. The method of the invention is additions and amendments to standard DZS200.35-94 <<Identification and statistical method for rock gas casting sheet >> of Petroleum Geology Marine Geology Board of Department of Geology and Mineral Resources and oil and gas industry standard SY/T6103-2004 <<Testing image analysis method for rock pore structure characteristics>>, and can be considered to be incorporated to new industry standard.

Description

technical field [0001] The invention relates to the field of identification of rocks and mines under a microscope, in particular to a method for making thin slices of rock void castings. Background technique [0002] Casting technology is a technology for pretreatment and processing of rock samples before identification under the rock microscope. The procedure is to first vacuum the rock sample, then pour the colored epoxy resin into the glass tube containing the sample, and then cast the epoxy resin into the pores of the rock by applying pressure and let it solidify. Then the samples were taken out and separated one by one, and finally the rock samples were ground into thin slices for observation and image analysis under a microscope. [0003] The method steps of making a plurality of rock sample castings in the prior art are: [0004] 1. First use a glass tube, put the samples in sequence, and put a piece of mica sheet with a cross-section similar to the glass tube as an...
