Method for characterizing the organic hydrocarbon compounds contained in a solid deposit of a geothermal installation

摘要

The present invention relates to a method for characterizing the organic hydrocarbon compounds contained in a solid deposit of a geothermal installation, by means of a measurement of a quantity of organic hydrocarbon compounds released by a sample of the solid deposit during heating by pyrolysis according to a sequence of temperatures such that: from a temperature (T1) between 50 ° C and 120 ° C, the temperature of a rock sample is raised to a temperature (T2) between 180 ° C and 220 ° C. Then, this temperature (T2) is maintained for a predetermined time. The temperature of the sample is increased to a temperature (T3) between 330 ° C and 370 ° C. This temperature (T3) is maintained for a predetermined time. Then the temperature of the sample is raised to a temperature (T4) between 630 ° C and 670 ° C. Figure 2 to publish.
