Abstract

The utility model relates to an electric heating oil exploitation device of a hollow oil pumping rod exceeding pump, comprising a special transformer 1, a power source cable 2, an electric control cabinet 3, a power supply cable 4, an oil pumping machine 5, a cable introducing device 6, a hollow oil pumping rod 7, an oil tube 8, a casing tube 9, a hollow circumfluence oil pumping pump 10, a heater 11 under a pump, a circuit connector 12, a cable 13, and a pump sleeve 14. The electric control cabinet 3 supplies alternating current to the power supply cable 4. The cable 13, the hollow oil pumping rod 7, and the heater 11 under a pump heat, the thick oil or the high coagulation oil on the upper side and the lower side of the hollow circumfluence oil pumping pump 10 and in the interior of the pump is heated to reduce viscosity, and easily flows. When the hollow oil pumping rod 7 is driven by the oil pumping machine 5 to move from top to bottom, the thick oil or the high coagulation oil is raised onto a ground to be transported.

Description

Electric heating oil-extracting apparatus of hollow sucker rod pump
The utility model relates to a kind of hollow rod and gets over the pump heating oil extraction device.
Coagulate in the oily process at Oilfield using sucker rod heavy crude producing, height, for successfully extraction viscous crude or height coagulate oil, usually need heat viscous crude in the oil well or the high oil that coagulates, reducing viscosity, to prevent wax deposition, the method for taking has steam injection, mixes thin oil, the heating of hollow stem alternating current.But hollow stem alternating current heater can only heat the oil of oil well pump top usually, can not the oil of oil well pump below be heated, and the viscous crude of pump below is difficult for entering in the pump, and the efficient of oil well pump is lower.
The purpose of this utility model will provide a kind of hollow rod to get over the pump heating oil extraction device exactly, makes hollow rod pass through pump.The hollow rod lower end connects heater under the pump, when heater passes to alternating current under giving hollow rod and pump, on the pump pump down and in the pump viscous crude or the high oil that coagulates be heated simultaneously, viscosity of thickened oil is reduced easily flow, the high oil that coagulates is difficult for wax deposition, effectively viscous crude in the extraction oil well or the high oil that coagulates.
The purpose of this utility model is achieved in that
The utility model comprises special transformer 1, feed cable 2, electrical control cubicles 3, electricity cable 4, oil pumper 5, cable introducer 6, hollow circulation oil well pump 10, pump block 14, oil pipe 8, sleeve pipe 9, feed cable 2 connects special transformer 1 and electrical control cubicles 3, electricity cable 4 is drawn from electrical control cubicles 3, pass cable introducer 6, heater 11 is connected with circuit connector 12 under hollow rod 7 and the pump, oil pumper 5 is connected with cable introducer 6, hollow circulation oil well pump 10 is connected with oil pipe 8, pump block 14 is connected with oil pipe 8, oil pipe 8 is positioned at sleeve pipe 9, sleeve pipe 9 and formation consolidation are together, it is characterized in that: the hollow rod 7 that is positioned at oil pipe 8 passes through hollow circulation oil well pump 10, hollow rod 7 upper end stube cable introducers 6, the lower end connects heater 11 under the pump, pass to cable 13 in the hollow rod 7, there is circuit connector 12 heater 11 lower ends under the pump, electricity cable 4, circuit connector 12, heater 11 under the pump, hollow rod 7 constitutes electric loop.
When passing to alternating current for electricity cable 4 by electrical control cubicles 3, electric current under electrical control cubicles 3, electricity cable 4, cable 13, circuit connector 12, pump heater 11, hollow rod 7, get back to electrical control cubicles 3, at this moment heater 11 heatings under cable 13, hollow rod 7, the pump, the heat that produces is passed to the crude oil in hollow circulation oil well pump 10 tops, below and the pump, make oil viscosity descend, be difficult for wax deposition, easily flow.When the upper and lower stroke of oil pumper, drive hollow rod 7 and move up and down.When hollow rod 7 moves downward, oil enters in the hollow circulation oil well pump 10 and hollow circulation pump oil well pump 10 tops from hollow circulation oil well pump 10 belows, when hollow rod 7 moved upward, the oil of hollow circulation oil well pump 10 tops was promoted to ground and is transported away.Like this, hollow rod 1 pumps, just constantly being drawn to ground and being transported away through the viscous crude of heating or the high oil that coagulates in the sleeve pipe 9.
The utlity model has hollow rod and pass through pump, the hollow rod lower end connects heater under the pump, when passing to alternating current, viscous crude or highly coagulate that oil is heated, viscosity reduces, be difficult for wax deposition in the pump under the pump on the pump, when oil pumper pumped, viscous crude in the extraction oil well or height coagulated oil effectively.
The utility model is provided by following examples.
Accompanying drawing 1 is a principle schematic of the present utility model
The utility model comprises heater 11, circuit connector 12, cable 13, pump block 14 under special transformer 1, feed cable 2, electrical control cubicles 3, electricity cable 4, oil pumper 5, cable introducer 6, hollow rod 7, oil pipe 8, sleeve pipe 9, hollow circulation oil well pump 10, the pump.
Special transformer 1 can adopt the single-phase special transformer of three phase transformations; electrical control cubicles 3 can have regulation voltage; overcurrent protection; temperature controlled function; oil pumper 5 can be selected homemade 10 type oil pumpers for use; cable introducer 6 and hollow rod 7 can adopt the 35CrMo material to make; oil pipe 8; sleeve pipe 9; pump block 14 can be selected 20CrMo for use; the 35CrMo material is made; hollow circulation oil well pump 10 can be made with alloy steel and stainless steel; heater 11 can be made with the high impedance metal material under the pump; circuit connector 12 can adopt the plug conductive paste to form; cable 13 is a heating cable, and feed cable 2 can be selected standard cable for use.
