FIELD: oil and gas industry, possible use for geophysical research of active wells. ^ SUBSTANCE: sensor of thermo-indication of liquid influx in a well contains indirect type heater, measuring sensor and well liquid temperature compensation sensor in unitized body. Aforementioned sensors and heater are positioned in heat-conductive paste and positioned in the body in following order, starting from the end of sensor: firstly, heater is mounted, then in close proximity of the heater - measuring sensor, then with a gap of at least 30mm from the latter - well liquid temperature compensation sensor. ^ EFFECT: increased sensitivity of thermo-indication of liquid influx in a well due to compensation of well liquid temperature. ^ 1 dwg |
