Abstract

The invention provides a device for detecting oil content of an oil shale by using a light reflection difference method. The device comprises an incident light path, a displacement platform, a sample cell, an emergent light path, a signal amplification device, a data acquiring and processing system and a base, wherein the incident light path comprises a laser, a polarizer, a photoelastic modulator and a phase switcher; the sample cell is fixed on the displacement platform; the emergent light path comprises a polarization analyzer, a diaphragm and an electro-optical signal converter; the laser, the polarizer, the photoelastic modulator, the phase switcher, the displacement platform, the polarization analyzer, the diaphragm, the electro-optical signal converter, the signal amplification device and the data acquiring and processing system are fixed on the base placed horizontally; the electro-optical signal converter is a photodiode; and the signal amplification device is a phase-locking amplifier. The device is simple in structure and easy to operate; signal-to-noise ratio is increased greatly; and the oil content of the oil shale can be measured quickly and accurately.

Description

technical field [0001] The invention relates to an optical instrument, in particular to a device and method for detecting the oil content of oil shale by difference in light reflection. Background technique [0002] Oil shale is a fine-grained sedimentary rock that is rich in organic matter, has micro-bedding, and can be burned. Its components mainly include kerogen, water and minerals, and the organic matter (usually 15% to 50%) is oil shale. The main components of medium kerogen are composed of carbon, hydrogen, oxygen, a small amount of sulfur and nitrogen. The proportion of shale oil is the oil content of oil shale, which is a key indicator for evaluating the grade of oil shale and a defining parameter for the concept of mineral resources. Accurately obtaining information on oil content is of great importance to the exploration, development and industrial utilization of oil shale. meaning. [0003] Low-temperature dry distillation (SH / T0508-92) is a traditional method ...
