In-well hyperspectral measurement system and measurement method

Abstract

The invention belongs to the technical field of hyperspectral measurement, and in particular relates to an in-well hyperspectral measurement system and a measurement method. In the system, a fiber optic turntable is used as a transit device in the in-well measurement of a spectrometer, and fibers in the fiber optic turntable are used as carriers for transmitting spectral measurement signals; the end of a measuring probe with a built-in light source is designed to be bent at a right angle of 90 degree to the vertical direction, and is mounted on the end of the fiber optic turntable and is suspended above a wellhead pulley; a motor is used to drive the fiber optic turntable to transport the measuring probe down the well; a portable computer is used to control the spectrometer for in-well spectral measurements. The invention fills the gaps of hyperspectral measurement technology in the well measurement applications, improves the timeliness of hyperspectral technology in deep geological exploration applications, and gives full play to the advantages of hyperspectral measurement technology in detecting deep material components.

Problems solved by technology

However, the drilling log generally pursues timeliness. Compared with traditional geophysical wells, the timeliness of core hyperspectral measurement is obviously insufficient, which limits the role of hyperspectral technology in deep exploration.

Moreover, the drill cores exposed from the deep are prone to weathering and change composition due to the influence of storage time on the surface and climatic conditions, which greatly reduces the application effect of core hyperspectral measurement information.
