oil and gas mud logging geology logging Oil Fluoroscope UV box
(1) Fluorescent dry and wet photos.
The washed cuttings, core, and wall of the well wall are placed under fluorescent light for dry and wet photos.
1 Oil-bearing cuttings, core, and wall of the well wall are light yellow, yellow, bright yellow, golden yellow, yellow brown, brown, brown, etc. under ultraviolet light. The oil quality is good, the luminescent color is strong and bright; the oil quality is poor, and the illuminating color is dark.
2 mineral fluorescence: quartz, opal white – gray; calcite, shell yellow – bright yellow; gypsum is bright sky blue, milky white.
3 refined oil and organic solvent: diesel is bright purple – milk purple blue; oil is blue – sky blue; butter is bright purple blue; silk oil is leucorrhea blue – dark blue; white oil, kerosene It is milky white with blue; sulfonated asphalt is yellow and light yellow; lead oil is red.
(2) Chloroform droplets.
1 Take a few samples of rock fragments, disperse on the filter paper, drop a drop of chloroform solution on the cuttings, observe the fluorescence diffusion and stain around the rock sample, and record the color, intensity and luminescence of the fluorescence.
2 The color of the fluorescent diffusing edge marks: the hydrocarbons are mostly sky blue, slightly purple – sky blue, the gum is yellowish brown, and the asphaltene is black-brown.
3 The mineral fluorescence has no diffusion phenomenon. The fluorescent color of the refined oil is lighter, and it is milky purple-sky blue. Generally, it only pollutes the surface of the cuttings. It can break the cuttings, core and wall to observe the fresh surface.
4 Excluding the oil pollution of the product and the fluorescence of the luminescent mineral, describe the color, intensity and the percentage of the rock debris, core, and core fluorescence.
