METHOD TO DETERMINE KEROGEN CONTENT IN ROCKS AND ITS PARAMETERS Russian patent published in 2013 - IPC G01N31/12

Abstract RU 2485495 C2

FIELD: measurement equipment.

SUBSTANCE: rock samples are taken. Crucibles are cleaned in an ultrasonic bath and tempered in a muffle furnace. Samples are ground in metal and agate mortars. Pyrolysis is carried out with subsequent oxidation of samples in an inert nitrogen atmosphere using a plant Rock-Eval-6. In the pyrolysis furnace of the plant Rock-Eval-6 free hydrocarbons are evaporated, thermal decomposition of kerogen takes place. Hydrocarbons released as a result of such decomposition are determined with the help of a plasma-ionisation detector. Also electric potential is measured, which occurs in process of ionisation in flame created by burning of a hydrogen-air mixture. Using the method of infrared spectrometry, quantities of CO and CO₂ are continuously measured. With the help of software Rocksix parameters of light loosely coupled hydrocarbons are determined.

EFFECT: determination of kerogen content in rocks and its parameters.
