Energy storage rotary heating mining device for bailing well

Abstract

The invention relates to an energy storage rotary heating mining device for a bailing well, and belongs to the technical field of oil extraction tools. The energy storage rotary heating mining devicefor the bailing well comprises a steel wire rope, a bailing pump, a weighting rod, a battery bin, a rotary driving part, a rotary joint and a rotary heater, wherein the steel wire rope, the bailing pump, the weighting rod, the battery bin, the rotary driving part, the rotary joint and the rotary heater are sequentially connected. A lithium battery pack and a remote control switch for controlling the power supply on and off of a battery are arranged in the battery bin, and the lithium battery pack is used for supplying power to the rotary driving part and the rotary heater. A rotator comprisesa screw-in device and a spiral heater encapsulated in a central inner cavity of the screw-in device. A spiral screw-in belt is arranged on the outer periphery of the screw-in device, the lower end ofthe screw-in device is in a cone tip shape, the screw-in device is in driving connection with the rotary driving part, and the spiral heater is electrically connected with the lithium battery pack through the rotary joint; and therefore, the energy storage rotary heating mining device for the bailing well has a simple external structure, on-site construction operation is facilitated, one-time completion of heating and mining is achieved, the cost is reduced, construction operation steps are simplified, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of oil extraction tools, in particular to an oil well energy storage rotary heating extraction device for low-yield heavy oil oil wells. Background technique [0002] The oil quality of the fishing well is poor, the wax content is high, the oil is thick, and the output is low. In the case of low ambient temperature, when the temperature of the crude oil in the well is lower than the condensation point temperature, the crude oil solidifies in the wellbore to form dead oil, and the oil is pumped. When encountering obstacles, normal oil fishing production cannot be carried out downward. In order to restore production, measures must be taken, and the operation process is often affected by climate, roads, underground geological factors, etc., which requires high operating costs. [0003] The electric heating production method of normal oil production wells is a wired AC power heating method. The principle is to ...

AI Technical Summary

Problems solved by technology

There are problems with this kind of equipment: 1) The ground must be driven by power equipment to transmit energy to the downhole. When fishing for oil, only the wire rope is used to lift and lower the oil pump, and there is no power equipment on the ground; 2) The power must be transmitted to the harmonic by the sucker rod The transmission converts energy, and there is no sucker rod for oil fishing; 3) Due to the limitation of casing space and device materials, the power generated by the generator is limited, and it is difficult to achieve the expected effect in practice; 4) The generator, heater and cables are placed for a long time In the underground, it cannot be inspected and repaired in time, and there are potential safety hazards

The problems of this kind of oil fishing equipment are: 1) During operation, heating and oil fishing are carried out separately, and the process is complicated; 2) In addition to the oil fishing equipment, an additional vehicle is required to install underground heating equipment, and an external power supply or generator needs to be provided on site; 3 ) The overall construction is complex and costly
