FIELD: oil and gas industry.
SUBSTANCE: down-hole testing and measuring complex includes earth control station with telemetric data system connected by a logging cable with submerged-type electric pump at the end of tubing string, system of measuring modules including sensors for recording of parameters (yield, pressure, temperature, moisture content) and driving machine for their delivery to horizontal section of a well connected by a logging cable that provides rigid mounting for the system of measuring modules and transfer of data to the control station. Logging cables of the system of measuring modules telemetric system unit are connected by cable connectors. Driving machine contains two walking modules connected electrically and further driven by electrical micro-drives and sequential movement of wedged supports. Installation of the down-hole testing and measuring complex is performed in two stages. At first system of measuring modules is lowered to a well by means of winch with survey cable connected by a cable connector with a logging cable of the system of measuring modules passing through a groove in the wall of an installation pipe mounted at the well surface at the end of tubing string and by the other butt end - to the deadman in which tube there is a movable logging cable. The system of measuring modules is lowered at first up to driving machine turning to a relatively horizontal section, then by means of the driving machine it is hold to the relatively horizontal section until cable connector seats in the deadman tube; the latter is lowered by means of the installation pipe to the preset depth and fixed on the well bore. Thereafter power supply is switched odd in the micro-drive, by means of the winch socket with the survey cable is disconnected from connector pin and the installation pipe is lifted to the surface. At the second stage submerged-type electric pump is lowered to the well with logging cable and socket of cable connector contact pair filled by liquid sealant which is by means of a centring skid connected to the logging cable for the system of measuring modules.
EFFECT: increase of operational efficiency during installation of the bottom-hole complex.
