Method of determining the maximum temperature undergone by a sedimentary rock, especially in the field of hydrocarbon formation |
摘要 |
A method of determining the maximum temperature undergone by a specimen of sedimentary rock during natural heating over a geological process, within the range from 60° C. to 230° C. approximately. The method includes analysis at very low temperature, down to a few kelvin, for example down to 10 kelvin, of the magnetic transitions intended to characterize an iron oxide and an iron sulfide that are formed or destroyed in the specimen by the geological heating of the sediment; and determination of the maximum temperature undergone by the specimen, using a calibration obtained by measuring the same magnetic parameters on the same sediment or on other sediments of the same nature, heated beforehand in the laboratory to known temperatures. |

1. A method of determining the maximum temperature undergone by a specimen of sedimentary rock during natural heating over a geological process, within the range from 60° C. to 230° C. approximately, comprising the following steps:
a. analysis at very low temperature, down to a few kelvin of the magnetic transitions intended to characterize an iron oxide and an iron sulfide that are formed or destroyed in the specimen by the geological heating of the sediment; and b. determination of the maximum temperature undergone by the specimen, using a calibration obtained by measuring the same magnetic parameters on the same sediment or on other sediments of the same nature, heated beforehand in the laboratory to known temperatures. |
