OIL HEATING PLANT - AN EFFECTIVE WAY TO ASPHALT SMALL PARAFFIN DEPOSITS

At present Russia in the overall balance of oil occupy a prominent position and high-viscosity paraffin oil, whose share has increased steadily. One of the problems complicating the extraction of oil, is the formation of asphalt-resin-paraffin deposits (AFS) in wells fixture.
The accumulation of sediments in the flow of oil field equipment and on the inner surface of the pipes leads to a decrease in system performance, reduce maintenance intervals of the wells and reduce the efficiency of pumping units.
The most intensive deposition of asphalt-resin-paraffin is on the inner surface of the lifting tube wells. Such complications are inherent in virtually all oil production complex in Russia and CIS countries with some features of the predominant content of asphalt-resin-paraffin in each field.
Addressing the asphalt-resin-paraffin deposits provide work for their prevention and removal.
There are several most known methods used in the oil industry, to combat the asphalt-resin-paraffin deposits:
  • mechanical method, involving removal of already formed deposits with scrapers of various designs;
  • chemical method, based on the introduction of metered well production of chemical compounds that reduce the formation of deposits;
  • thermal method of well treatment.
    Thermal methods are based on the ability of asphalt-resin-parafinnovyh deposits do not form a solid phase or melt at temperatures above their point of deposition or crystallization (for example, paraffins 35-500C). To create the desired temperature requires a source of heat, which must be placed directly into the zone deposits. Currently, as a heat source is used:
  • hot oil or water;
  • Superheated steam;
  • reagents, the interaction that occur exothermic reactions;
  • special heating cables.
    Numerous field research showed that the most effective way of dealing with asphalt-resin-paraffin deposits in wells is a thermal method with the use of heating cables in the installation of heating oil.

Load-carrying heating cable in direct contact with the downhole fluid, so the heat transfer is going directly into the liquid.
    For wells equipped with SRP and screw pumps, electric heating fluid in the borehole by means of a flat heating cable CNR, attached with metal belts (klyamsy) to the outer surface of the tubing. Cable is installed in the well simultaneously with the drain tubing and pump, which greatly reduces installation costs.

    Heating cables NAMES CNR
    Heating cables are designed to mark CNR heating wells equipped with screw and sucker-rod pumps (SRP) and installed in the annular space. Cables have a planar shape and are mounted on the outside of the tubing with metal brackets, similar cables for submersible pumps. The descent and ascent of a flat heating cable is made simultaneously with the column tubing. Control heating and placement of equipment similar to CR-H-800-100-U1 App. Used with heating cables brand REAG. Despite the lower efficiency of heat transfer of this method the cable, available performance data showed a complete fitness system for dewaxing wells with SRP and PCP. And there is experience in installations in batch mode, ie at night to heat, then a few days break, which corresponds to cyclic hot oiling, but it makes the use of hot oil. In general, a periodic regime is most favorable in terms of economy and overall reduction in power consumption. However, the possibility of periodic heating and parameters defined services VET oil companies, as in this case, the most important criterion is the composition of the borehole fluid, the percentage of paraffins, the rate of their deposits, etc.

    The specialists of JSC "Stavropol Radioworks" Signal "was developed and successfully applied the method fastening, sealing and lowering the heating cable brand REAG downhole valve. The descent and ascent heating cable round match standard works with geophysical armored cable and is similar in view of its diameter.


    UNIT descent and ascent TSA-50
    IZHSK.483111.001-01


    DESIGNATION
    The unit is designed for tripping with the use of cables for different purposes, including heating.

    CONDITIONS The unit provides a reliable and stable operation under the influence of these climatic factors:
  • upper ambient temperature + 40 ° C;
  • lower ambient temperature
  • minus 40 °C;
  • atmospheric pressure 650-800 mm Hg.

    BASIC PARAMETERS
    1 Cable diameter, mm 24 / 26
    2 Capacity of the drum unit, m3 1,5
    3 Traction force on the first two series of winding, KN, not less 35
    4 The speed of winding / coiling on a drum m / min 15/20
    5 Accessory drive electric
    6 Voltage in 380
    7 AC Frequency, Hz 50
    8 Power consumption, kW, not more 15
    9 Weight of the unit (without cable), kg, not more 1650
    10 Dimensions, mm - length - width - height 2740 2000 1938

    USING THE UNIT descent and ascent TSA-50
    Slope and rise of the cable with the unit of HSA-50 according to one of the options below:
    Option 1. The descent and ascent heating cables by using the unit TSA-50 and a crane, a block of commercials, balance, one of which is fixed on the borehole valve, and the other on the hook crane. Due to the large diameter heating cable must be used rollers block balance diameter 800-1000mm.
    As a sealing device is used wellhead seal SU-73-25. Mounting load-carrying heating cables by means of two locks (zhimok with a rough surface).

    Option 2. The descent and ascent heating cables by using the unit TSA-50 and a special roller console attached to the downhole valve. Roller console has two rollers with a diameter of 750 mm and brackets for installing the lock fixing the heating cable. This design is installed on the downhole valve allows operation on the descent and rise of cable with TSA-50 without using a crane or other additional equipment. Sealing of cables by means of the wellhead flange SU-73-25. Fixing the cable provided with 2 locks, one of which, the main (zhimok with a rough surface), fixes the cable on the reference site. The second lock, fears, cone type, mounted on the upper end of the cable is attached to the outer armor wire poviva. It is designed to provide electrical contact with wire armor and protects the cable from falling into the hole in the case of weakening the main castle.

    ECONOMIC EFFICIENCY
    Oil-producing companies, plant operators of heating oil УН-Н-800-100-У1 different performances indicate that their implementation can:
  • Exclude clearing tubing mechanical scrapers.
  • Increase the life of the submersible equipment more than doubled (700 days or more) - at the expense of non-stop pump and reduce the load due to lower viscosity oil in the lift well.
  • Reduce watering of the extracted fluid, stabilize the work of the reservoir.
  • Remove cooked outlet pipe (500 m) even at low temperatures.
  • Significantly increase productivity and extend the work of well between repairs.
  • Enlarge a turnaround time of an electric pump.
  • Reduce the loss of oil production due to exceptional downtime wells downhill, uphill scrapers during overhauls.
  • Reduce the loss of oil production, spent on the thermal treatment wells.
  • Significantly reduce maintenance costs of wells.


    Installation of heating oil produced by JSC "signal" successfully used in many oil-producing companies in Russia and CIS countries.
