FIELD: geophysics.
SUBSTANCE: invention relates to geophysical engineering and can be used to conduct hydrothermodynamic studies of seams and, mainly, steam injection wells, in particular, to clarify the geological and hydrodynamic model of the reservoir and reservoir, to control the productivity of the wells. Complex device made in the form of a vertically elongated housing in which a temperature sensor is placed, a pressure sensor and a locator of continuity connected to a geophysical cable, which is made possible via a cable head in the upper part of the signal transmission housing from the temperature sensor, pressure sensor and continuity locator to an external geophysical logger. And, as a pressure sensor, a string sensor with an open input is used, a string sensor with a closed input filled with a high-temperature liquid in a mixture with an inert gas is used as a temperature sensor, and in string sensors, the right and left parts of the cylinders are made with diameters differing by 2 mm, and the axes of the cylinders are displaced relative to each other by 1–2 mm, while the string pressure sensor has a string thickness of 0.22 mm, a string temperature sensor has a diameter of 0.24 mm, and their body and tightening strings are made of a single piece.
EFFECT: increased accuracy with simultaneous expansion of functionality of the complex device.
