APPARATUS AND METHODS FOR GAS VOLUME RETAINED CORING

摘要

It may include tool that one kind, which being used in wellbore, and there is the first section and the second section to be configured to receive core and be arranged to collect rocket escaping and remove from core. The equipment can also include sensor, and to provide the one aspect in the related gasoline of the associated attribute of signal, second segment can be dismountable and can be pressurized. The device may also include that record data representative of logger from sensor received signal. Logger can recorde data, and tool is fetched from the wellbore simultaneously. For estimating that the parameter of concern on stratum, including retrieval core are withdrawn into ground from stratum acquisition rocket escaping from type core, ground is withdrawn into while measuring at least one characteristic of gas.
