Manometer-thermometer autonomous MTA (MTLA)
Appointment
Stand-alone pressure gauges of the MTA series (MTLA) are designed to register pressure and temperature values, as well as, in the presence of a coupling locator, to detect coupling joints and explosive perforation zones.
They are used in the study of oil, injection, gas and other wells using a scraper wire or other methods of delivering devices to the study area.
Permission to apply № РРС 00-34550 issued by the Federal Service for Ecological, Technological and Nuclear Supervision.
Opportunities
High accuracy and resolution allow the use of autonomous pressure gauges for:
- building an inflow profile;
- determination of water and gas-oil contacts;
- determination of the dynamic level of annular fluid;
- detection of leakage of coupling joints;
- studies of reservoir properties.
Features
Setting the operating mode and reading information into the computer is via the USB port.
Setting up to 8 data recording intervals with setting different modes in each interval: the registration period and the duration of the registration interval.
The duration of continuous data recording depending on the registration period is from 284 hours to 3 years.
The duration of continuous operation when using one AA-size battery is up to 300 days.
The use of high-quality materials in the manufacture of pressure gauges ensures their reliable operation in wells with an operating temperature of up to 150 ° C and with an H2S content of up to 30%.
Technological software allows you to set the operating modes of the pressure gauge, check the condition of the batteries, view and print the recorded values in the form of tables or graphs, integrate and correlate the depth of the pressure gauge with the readings of other devices.
Execution
Self-contained pressure gauges are available in diameters from 20 to 42 mm, with or without locator couplings, and can have a lower threaded connection for inclusion in the autonomous recording complex.
