Abstract
The utility model discloses a movable electrical heating well washing device. The movable electrical heating well washing device is provided with an electric heater, a liquid inlet pipe and a liquid outlet pipe on a tank body. A liquid outlet which is used for residual liquid drain is formed in the bottom of the tank body. A liquid outlet valve is arranged on the liquid outlet. When well washing begins, low temperature oil pumped from the oil well by the liquid inlet pipe as well washing liquid is heated through the electric heater. High temperature oil is discharged into the low temperature oil well through the liquid outlet pipe to wash the low temperature oil well. When well washing is finished, the liquid outlet valve is opened and the residual liquid remains in the bottom of the tank are discharged from the liquid outlet. Residual liquid around the bottom of the tank body is converged at the bottom of the tank body under the effect of gravity and are discharged from the liquid outlet. Due to the fact that the movable electrical heating well washing device heats the low temperature oil in the low temperature well circularly, wash of the low temperature well is achieved. Through consuming less power to finish the well wash, power consumption is low and well wash cost is reduced.

In order to realize above purpose, the technical scheme that the utility model adopts is:
The technical scheme of Moveable electric-heating well-cleanout apparatus of the present utility model is as follows:
A kind of Moveable electric-heating well-cleanout apparatus, comprise be used to the tank body that holds flushing fluid, be provided with electric heater for heating tank body wash-in well liquid on the described tank body, be used for flowing into feed tube in the tank body, being used for the drain pipe that flows out in the tank body for flushing fluid for flushing fluid, described tank body has for the bottom that holds residual liquid after finishing at well-flushing, the bottom of tank body offers leakage fluid dram, is equiped with tapping valve on the described leakage fluid dram.
Also offer on the described tank body for the thermometer hole for temperature measurer or temperature transducer insertion.
Described tank body be shaped as column, described electric heater is in the two ends of tank body.
Described feed tube is in the bottom of tank body, and drain pipe is in the top of tank body.
Control connection is useful on the control device of control electric heater work on the described electric heater.
The utility model adds electric heater, feed tube and drain pipe at tank body, and offer the leakage fluid dram of discharging for for residual liquid in the bottom of tank body, install tapping valve at leakage fluid dram, when the beginning well-flushing, can extract low temperature oil in the oil well as flushing fluid by feed tube, in tank body, after electric heater heating, by drain pipe high temperature oil is entered in the low temperature oil well low temperature oil well is carried out well-flushing; When finishing well-flushing, open tapping valve, the residual liquid that remains in tank base is discharged from leakage fluid dram, be in tank base residual liquid on every side can collect in tank body under Action of Gravity Field bottom, also discharge from leakage fluid dram, guaranteed that to greatest extent residual liquid can discharge from tank body, therefore the utility model is by the circulating-heating to low temperature oil in the low temperature oil well, realize the well-flushing of low temperature oil well, finish well-flushing by consuming less electrical energy, energy consumes low, thereby has reduced the well-flushing cost, solve in the prior art well-flushing of low temperature oil well and needed to adopt " boiler car+tank car ", the problem that Expenses Cost is high.And because flushing fluid is high temperature oil, strong with the compatibility of oil reservoir, shortened the convalescence of oil well behind the well-flushing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The embodiment of Moveable electric-heating well-cleanout apparatus of the present utility model, as shown in Figure 1, this device comprises tank body 1, control device 2, imported valve 3, feed tube 5, drain pipe 4, supporting leg 6, wire 7, flow meter 8, tapping valve 9, electric heater 10, temperature measurer 11, tank body 1 be shaped as column, electric heater 10 is installed in the two ends of tank body 1, the bottom of tank body 1 offers leakage fluid dram and import, tapping valve 9 is installed on the leakage fluid dram, feed tube 5 is communicated with in import, and is provided with imported valve 3 and flow meter 8 at feed tube 5 strings.Tank body 1 is erected on two supporting legs 6.The top of tank body 1 offers thermometer hole and outlet, is equiped with temperature measurer 11 in the thermometer hole, and outlet is communicated with export pipeline 4, and string is provided with outlet valve on the export pipeline 4.Control device 2 is by wire 7 and tank body 1 control connection, and with 1140 volts power connection.
Described liquid inlet and outlet pipe 5,4 is heat-resistant hose, thereby guarantee in use, the stability of liquid inlet and outlet pipe 5,4 work, avoid oil temperature too high by liquid inlet and outlet pipe 5,4 oil well that ignites, and stop liquid inlet and outlet pipe 5,4 to expand with heat and contract with cold the problem into and out of instability of flow that distortion causes.
The utility model in use, and is as flushing fluid, interior after electric heater 10 heating at tank body 1 by the low temperature oil in the feed tube 5 extraction oil wells when the beginning well-flushing, by drain pipe 4 high temperature oil entered in the low temperature oil well low temperature oil well is carried out well-flushing; After well-flushing finishes, remain in the bottom that residual liquid in the tank body 1 can be gathered in tank body 1, this moment can just can be emptying with the residual liquid in the tank body 1 by opening tapping valve 9, thereby prevented from being the problem of freezed in winter and residual liquid erosion electricity price body tank body 1 is vacant; Control device 2 of the present utility model is selected 1140 volts power supply, with the power supply difference of 380 couchers industry commonly used electricity consumption, thereby reaches the purpose that prevents from stealing electricity; Tank body 1 has adopted the structure of bottom in and top out, so that in electric heater, the cleaning liquid that heats is in the not upper strata of heated wash liquid, thereby has guaranteed that the liquid that flows out is the liquid that heats, and has improved cleaning performance from fuel-displaced pipeline; Monitor constantly the temperature of tank body 1 cleaning liquid inside body by being arranged on temperature measurer 11 in the thermometer hole, the temperature that guarantees cleaning liquid is moderate, and adjust constantly the duty of control device 2 by the temperature that shows on the temperature measurer 11, guarantee the temperature domain of walker temperature of tank body 1 cleaning liquid inside body.
