MEASUREMENT OF GAS CONTENT IN NON-TRADITIONAL CONTAINER ROCKS Russian patent published in 2015 - IPC E21B49/08 G01N1/22 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement of total gas content in non-traditional container rocks, such as gas-bearing container beds, which may be found in sedimentary rocks, volcanic or metamorphic rocks. The method includes stages of well drilling in the measurement range in a container bed to create a volume of drilling mud in annular space, which contains fragments of drilled rock and gas. At the same time the volume of annular space has the front edge and the rear edge, diversion of the front edge of the annular space volume so that entire volume of annular space is trapped in a degassing system for storage without its exposure to atmosphere, interruption of diversion of annular space volume after trapping of the front edge of annular space volume in the degassing system for storage in order to determine quantity of gas in terms of annular volume; and also in-situ calculation of the total gas volume in the container bed with account of gas and fragments of drilled rock in terms of fragments of drilled rock and gas, contained in the annular space volume.

EFFECT: increased reliability and accuracy of the method and the device for measurement of total gas content in non-traditional container rock.
