Abstract

The invention discloses an apparatus for real-time online identification of strata lithology and identification method thereof, which relates to real-time online monitoring of lithology during the process of oil logging. The apparatus consists of a pulse generator (1), a pulsed laser (2), a sequence controller (3), a mesopore reflector (4), a holophote (5), a focusing mirror (6), a reaction chamber (7), a flow valve (8), a drilling liquid pool (9), a photoelectric receiver (10), optical fibers (11), a spectrometer (12), ICCD (13) and a computer (14). Cutting grains of drilling strata remained in drilling fluid are excitated to high-energy state by using focusing laser beam of high energy. During the transition of cutting grains from the excited state to the ground state, the components of cutting grains radiate their respective spectrums. By analyzing the characteristic spectrums, the elements and their corresponding concentrations of the samples are obtained and the lithology thereof are determined. The apparatus has the characteristics of simple structure, reliable method and easy operation, thus is suitable for real-time online detection of strata lithology during the process of oil logging.

Description

technical field [0001] The invention relates to oil mud logging, which is mainly used for real-time and on-line detection of formation rock lithology encountered in the oil mud logging process. Background technique [0002] Comprehensive geological logging is an important means to cooperate with drilling to explore oil and gas. It is a method to observe, detect, judge and analyze underground rock properties and oil and gas conditions by using various data and parameters along with the drilling process. It mainly includes geological logging, gas logging, and engineering logging, which can be further divided into cuttings logging, core logging, drilling-time logging, fluorescence logging, engineering parameter logging, all hydrocarbon components and non-hydrocarbon Gas logging, etc. [0003] Debris logging is the most direct primary data for understanding subsurface lithology and oiliness in field geological logging. Through cuttings logging, the lithology characteristics of...
