Abstract
The utility model discloses a thermal washing wax-melting device of thickened oil. The thermal washing wax-melting device of the thickened oil is composed of an oil pipe [1], the thermal washing wax-melting device [2], a tubing anchor on a pump [3], a packer [4], an oil extraction pump [5] and a screen blocking [6]. The thermal washing wax-melting device of the thickened oil is characterized in that the oil pipe [1], the thermal washing wax-melting device [2], the tubing anchor on the pump [3], the packer [4], the oil extraction pump [5] and the screen blocking [6] are connected in sequential mode. The thermal washing wax-melting device of the thickened oil can conveniently backwash wax precipitation of the oil pipe on an oil well pump to the ground, cleans the wax precipitation of an oil well, and improves yield of the oil well.
Description
Affiliated technical field
A kind of viscous crude heat that the utility model relates on the oilfield is washed wax melting device, this device has oil pipe [1], heat to wash tubing anchor [3] on wax melting device [2], the pump, packer [4], oil extraction pump [5], screen blinding [6] composition, use this device can be easily with the wax deposition backwash in the oil pipe on the oil pump to ground, remove the wax deposition in the oil well, improve oil well output.
Background technology
At present, known technology is not establish on the oil pump heat to wash wax melting device on the down-hole string of oil well, and its major defect is that the wax deposition in the oil well is not easy to remove, and the crude oil of extraction easily stops up petroleum pipeline, causes heavy losses often for Petroleum Production unit.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of viscous crude heat to wash wax melting device, and this device can be removed the wax deposition in the oil well easily, improves oil well output.
The technical scheme that its technical problem that solves the utility model adopts is: adopt a kind of viscous crude heat to wash wax melting device, this device has oil pipe [1], heat is washed wax melting device [2], tubing anchor on the pump [3], packer [4], oil extraction pump [5], screen blinding [6] forms, it is characterized in that: oil pipe [1], heat is washed wax melting device [2], tubing anchor on the pump [3], packer [4], oil extraction pump [5], screen blinding [6] is linked in sequence, the effect that heat is washed wax melting device [2] is the anti-flushing well that helps to realize tubing string on the pump, the effect of tubing anchor on the pump [3] is tubing string on the fixed pump, the effect of packer [4] is that envelope is cut oil sets annular space, oil extraction pump [5] effect is to be responsible for downhole crude is given rise to ground, the effect of screen blinding [6] is to filter the crude oil that enters in the oil extraction pump [5], improve the operating efficiency of oil extraction pump [5], use this device can be easily with the wax deposition backwash in the oil pipe on the oil pump to ground, remove the wax deposition in the oil well, improve oil well output.
The beneficial effects of the utility model: by field trial, the utility model compared with prior art, use this device can be easily with the wax deposition backwash in the oil pipe on the oil pump to ground, remove the wax deposition in the oil well, improve oil well output.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the schematic diagram that a kind of viscous crude heat is washed the structure embodiment of wax melting device.
Among the figure: 1. oil pipe, 2. heat is washed wax melting device, 3. tubing anchor on the pump, 4. packer, 5. oil extraction pump, 6. screen blinding, 7. artificial bottom of a well, 8, oil well casing.
The specific embodiment
In the accompanying drawings, adopt a kind of viscous crude heat to wash wax melting device, this device has oil pipe [1], heat is washed wax melting device [2], tubing anchor on the pump [3], packer [4], oil extraction pump [5], screen blinding [6] forms, it is characterized in that: oil pipe [1], heat is washed wax melting device [2], tubing anchor on the pump [3], packer [4], oil extraction pump [5], screen blinding [6] is linked in sequence, the effect that heat is washed wax melting device [2] is the anti-flushing well that helps to realize tubing string on the pump, the effect of tubing anchor on the pump [3] is tubing string on the fixed pump, the effect of packer [4] is that envelope is cut oil sets annular space, oil extraction pump [5] effect is to be responsible for downhole crude is given rise to ground, the effect of screen blinding [6] is to filter the crude oil that enters in the oil extraction pump [5], improve the operating efficiency of oil extraction pump [5], use this device can be easily with the wax deposition backwash in the oil pipe on the oil pump to ground, remove the wax deposition in the oil well, improve oil well output.
