FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas industry and can be used at capital and current repairs of well. The instrument for pressure testing consists of temperature sensors, collar locators, block of processing and returning of results of investigation and a conductor and support cable. The instrument is equipped with electro-mechanical packer with controlled valve, pressure sensor, installed under the packer, liquid meter and pressure gauge, arranged at the line of operating liquid supply into well. The instrument additionally contains a well thermo-inductive indicator and a pressure sensor installed over the packer.
EFFECT: upgraded resolution at simultaneous reduction of time for well investigation, and also upgraded accuracy of location of leakages in well and of intervals of existing disorders.
