METHOD AND DEVICE FOR DETERMINING PETROLEUM CHARACTERISTICS OF GEOLOGICAL SEDIMENTS

摘要

P - The invention relates to a method for determining at least one petroleum characteristic of a geological sediment sample, in which the sample is heated in an oxidizing atmosphere, its temperature being raised successively to a first then a second value, said first value below 200 ° C being reached very quickly and then kept substantially constant for a certain time, said second value between 600 ° C and 850 ° C being reached according to a temperature gradient of between 1 and 30 ° C / min, from said first value. According to the invention, the amount of SO2 contained by the effluent resulting from said oxidative heating is measured continuously, at each instant of the heating period of said sample. / P
