FIELD: oil and gas.
SUBSTANCE: present group of inventions relates to the research of deep rock formations, namely to method and device for logging during well drilling. The system for the placement of the device to be run in the well contains a sub with tubular walls and an internal opening, which is connected to the drill string. The sub contains at least one slot providing a channel for the signal. The sub contains devices for providing a pressure barrier between the spaces inside and outside the tubular wall in the said slot, the said devices for providing the barrier being located inside the axial channel of the sub. The device to be run in the well has means for coupling with the sub on the upper and lower ends. The upper and lower coupling means of the device to be run in the well are designed so that they can be selectively disconnected from the sub. The method of positioning the device to be run in the well inside the sub on the drill string interval contains the following stages: device to be run in the well is adapted through the drill string to the sub providing a channel for signal passing, and the means for providing the barrier inside the axial channel of the sub for forming a pressure barrier between the spaces inside and outside the tubular wall of the sub. The drill string with the sub is positioned inside the deep formation, the drill string being equipped with a device located in its internal axial channel, near the said sub. The device to be run in the well is positioned inside of the drill string for coupling with the device located in the internal axial channel the drill string.
EFFECT: simpler and reliable system for borehole investigation in process of drilling.
