Oil branch equipment
Oil well heating control unit
At the present time in Russia in the overall balance of oil occupy a prominent position and high-viscosity paraffin oil, whose share is growing steadily. One of the problems complicating the extraction of oil, is the formation of asphalt-rubber-paraffin deposits (AFS) in the borehole valve. The accumulation of sediment in the flow of oil field equipment and on the inner surface of the pipes leads to a decrease in system performance, reduce the turnaround time of the well and lowering the efficiency of pumping systems.
The most intensive deposition of asphalt-rubber-paraffin is on the inner surface of the lifting tube wells. Such complications are inherent in almost all oil complex of Russia and the CIS with a difference in the predominant content of asphalt-resin-paraffin in each field.
Solving the problem of the AFS provide for their prevention and udaleniyu.Stantsiya designed to heat and protect the heating cable with copper, aluminum or steel wires DC and is designed to heat the tubing or pipelines to reduce the AFS on the tube walls. The station is designed to work outdoors in conditions regulated to climatic performance UHL1 GOST 15150-69 under the following climatic conditions:
- The ambient temperature from -60°C to +50°C;
- Relative humidity 100% at + 25°C;
- The environment must not be explosive, containing no corrosive gases and vapors at concentrations that deplete the metal and insulation, not saturated conductive dust;
- Altitude less than 1000m. The degree of protection of the station from the environment IP43 according to GOST 14254-80.
Feeding station is three-phase AC 380V 50Hz. Full performance station is stored at a deviation from the nominal voltage values ranging from -30% to +30%. Output voltage station depends on the circuit on and regulated by the 0-540V at power supply voltage 380 V (use jumper) and 0-1200V at a supply voltage 850V (using step-up transformer).
The station is in the structure of controller, which provides the ability to pass parameters and control via MODBUS. The controller provides a stable work station, the protection in many ways, provides archiving of events in its internal memory.
