4 Sampling
ZB E11 H)2-89
4.1 Samples for fluorescence identification: Do not soak in organic solvents before making slices. 4.2 All samples must be analyzed under ultraviolet light. Select representative parts: Take out with gallium, wrap with water, and make slices.
4.3 Select a rock chip with the same properties as the fluorescent sample and make polarized slices to facilitate comparison and observation with fluorescent slices. 5 Sample preparation
5.1 Process
Slice → Polish and cut → Sticky slice → Brush slice → Paste, etc. 5.2 Slice making requirements
5.2.1 Slice according to the sample delivery month, cut selectively, such as for reservoir space research, try to cut through the seam, full, and tied places: For oil-producing research, attention should be paid to cutting along the muddy skin and the parts rich in organic matter, 5.2.2 Make smooth thin sections of samples, it is recommended to cut with loose cracks or thousands of t. Use T-2 or K-2 type 502 glue for glueing: For oil sandstone with poor paintability, use K-1 type 52 glue: Calcium infiltration: Use purified tar amine to make the surface, 5.2.3 When rough grinding the surface, if there is loose rock with falling particles, use glue to glue it again, and then smooth it until all the holes are correct.
5.2.4 Fourth grinding: Polish the surface
5.2.5 Fine grinding: Grind the mirror surface.
5.2.6 Cut the piece to make rough glass.
5.2.7 After the moisture content of the sample is reduced to 10%, it can be used for mounting. The bubble content in the sample slice can be as small as 3% of the slice area: Generally, the bubble content in the sample slice does not exceed 3% of the slice area. 5.2.8 When grinding the slice, coarsely grind to 0.10mm, finely grind to 0.06~0.07mm, and finely grind to 0.04-0.5mm. 5.2.9 Thin slices without fluorescence are generally not covered. Samples that are easy to deliquesce or fall must be covered: 6' Identification procedures
1. After the rock structure, composition, evolution and porosity are observed under a polarizing microscope, optical observation is carried out. 6.11 Content of minerals in carbonate rocks, structure, species, changes in mineral composition, content of minerals, sequence or evolution of mineral formation, causes of fractures, fillings, formation conditions, etc. 6.1.2 Clastic composition, whether it is structural, composition and content of minerals, formation sequence, cavity type: grain contact relationship, pore characteristics 6.1.3 Special rock types (pyroclastic deposits: igneous, metamorphic rocks), formation, structure, pore type, fracture type, fillings, formation conditions, etc. 6.1.4 Mixed rock, whether it is structural, whether it is structural, composition and content of minerals, sequence of formation, cavity type: grain contact relationship, pore characteristics, etc. 6.1.4 Mixed rock, whether it is structural, whether it is structural, composition and content of minerals, sequence of formation, cavity type: grain contact relationship, pore characteristics, etc. 6.1.3 Special rock types (pyroclastic deposits: igneous, metamorphic rocks), formation, structure, pore type, fracture type, fillings, formation conditions, etc. 6.1.4 Mixed rock, whether it is structural, whether it is structural, composition, content of organic residues, formation conditions, and relationship with other minerals: carbonate minerals or other grains. 6.2 Observation under a fluorescent microscope: 6.2.1 Reflected light is used to observe the general oil-bearing samples: 6.2.2 Reflected light is used to observe the medium layer, the natural blue, the blue material in the fine cracks and other organic rocks. 6.2.3 Asphalt composition, content and skin properties are indeed standard ZB E11 002-89
The color of luminescence reflects the composition of asphalt: The brightness of luminescence reflects the content of asphalt: The luminescence occurrence, the distribution of asphalt in solid rock and the sum of organic residues and phase minerals reflect the genetic properties of asphalt. 6.2.3.1 The relationship between color and composition is shown in Table 1 Table 1

Oil asphalt
Glossy asphalt

Luminescence color
Yellow, yellow-white, light yellow, green-yellow, light green-yellow, yellow-green, light yellow-green, green, light green, blue edge, light blue-green, green-blue, light green, blue, vegetable, light blue, white, light salt white, white with orange as the main color: brown-orange, light orange, light environment, yellow-orange, light yellow with brown as the main color, brown, light brown, olive lettuce, light orange-brown, yellow-brown, light yellow-brown non-luminescent (all black)
The relationship between luminescence intensity and asphalt content is shown in Table 2. Table 2
Luminescence intensity
6.2.4 Observation under microscope
6.2.4.1 Carbonate fluorescence identification
Carbonate rock and mudstone can share the same identification form, see Appendix A (supplement). After observing the percentage of mineral, debris and cement components and the degree of secondary changes in the stone under a polarizing microscope, the naming principle is then used to name the rock. In addition to the contents filled in the table of Appendix A, the following requirements are required:
a. Basin fluorescence display describes in detail the development of fractures and holes in the basin debris itself, the extension range, luminescence (intensity: range, location, color, color halo), etc.;
b. Cement fluorescence display, it is also necessary to collect: the relationship between grain size and the nature of the rock, the relationship between cement and secondary pores, holes and fractures, and oil-bearing display, etc.
C. The fractures should describe the type of fracture genesis; the relationship between fractures and matrix; the luminescence display should record the direction of impregnation, range color, color halo, intensity and luminescence location in detail, and pay special attention to the luminescence display of late fractures; d. Holes and caves are basically similar to fractures, and the formation causes, time and relationship between caves and fractures should be collected; e. When describing the characteristics, it should be noted that the description should not be repeated with the contents of each column in the table. On the basis of reflecting the objective reality, conclusions, inferences, discussions, research and other descriptions should be made in order. 6.2.4.2 Fluorescence identification of debris is shown in Appendix (Supplement). In the identification process, attention should be paid to the collection of the following contents: a. The relationship between the alteration of debris particles and oil content; b. The relationship between the pore type and formation time and the relative time of oil content; Z.BF11289
. The expansion sequence of cement, filling conditions, evolution process and its influence on oil and gas content. (24.3 Special types of luminescence characteristics, see Appendix (Supplement) During the identification process, the luminescence color and brightness of the pores and cracks should be described: the color halo is diffused in the hall, and the difference between the station material and the filling plastic and the replacement material should be distinguished in detail: 2.4.4 Mudstone
In addition to the description of the luminescence characteristics of non-oil rocks, the carbon light display of the pores and cracks in the mudstone should also be paid attention to. 7 Photography

Quality inspection requirements
Each batch of samples shall be repeated or stored for 10%, and their luminescence conditions must be consistent. The luminescence color color standard allows an error of 0.5 color level, region:
