Abstract
The utility model provides a solar heating and de-waxing device for well raw liquor. A raw liquor pipe is communicated with a booster pump, a raw liquor circulation tank and a sleeve outside an oil pipe; a heating mechanism has a superconductive heat exchange device arranged in the raw liquor circulation tank; the raw liquor is heated to the working temperature in the raw liquor circulation tank, and is led into the sleeve to remove the wax on the inner wall of the oil pipe; and a circulating pump, a solar thermal collector and the superconductive heat exchange device of the heating mechanism are communicated through a medium circulating pipe. The solar heating and de-waxing device for well raw liquor utilizes solar energy for heating to extract the raw liquor, reinjects the heated raw liquor to improve the temperature of the oil pipe and melts the wax on the inner wall of the oil pipe, so as to save the cost of wax removal and prevent pollution of underground oil layer; therefore the solar heating and de-waxing device has good promotion and use value.
Description
1, technical field
The utility model relates to a kind of well head sleeve pipe paraffin removal technology, and specifically a kind of down-hole stoste solar energy heating removes wax apparatus.
2, background technology
The down-hole casing wax deposition is the problem that often runs in the oil production technology.Wax deposition reaches certain thickness, not only can influence crude oil yield, also can cause Ka Jing, and oil pumper can't normally be moved.Now usually the paraffin removal method that adopts is that boiler hot is washed and added chemical agent, and under low temperature environment and be subjected to the influence of oil product, the paraffin removal cycle is short, frequency is high, and the cost of use of these two kinds of methods all is quite high, and cost of winning significantly increases.And most of heat are washed also and might be polluted to oilbearing stratum, and are totally unfavorable to later oil extraction.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of green energy resource that utilizes is provided, and control automatically prevents that the down-hole stoste solar energy heating of oil layer pollution from removing wax apparatus.
The technical solution of the utility model realizes that in the following manner the oil pipe sample valve is communicated with the outer sleeve pipe of booster pump, stoste circulating tank and oil pipe by the stoste pipeline.Heating arrangements is provided with the superconduction heat-exchanger rig in the stoste circulating tank, stoste is directed in the sleeve pipe be heated to operating temperature in the stoste circulating tank after, removes the wax of internal surface of sleeve pipe.The circulation pump of heating arrangements, solar energy collector and superconduction heat-exchanger rig are communicated with by the medium circulation pipeline.
The utility model has the advantages that:
1, utilize inexhaustible, the solar energy not to the utmost used as main energy sources, save cost, the protection environment can start the auxiliary heating of electricity under the special climate condition;
2, disposable input can move use at Duo Koujing, has reduced the oil extraction cost;
3, utilize the stoste re-injection paraffin removal of down-hole, solved the problem of oil layer pollution.
4, description of drawings
Accompanying drawing 1 is the structural representation that down-hole stoste solar energy heating removes wax apparatus.
Mark in the accompanying drawing is represented respectively: oil pipe sample valve 1, booster pump 2, stoste circulating tank 3, sleeve pipe 4, superconduction heat-exchanger rig 5, circulation pump 6, solar energy collector 7, fluid infusion case 8, fluid infusion pump 9, electrothermal furnace 10.
5, the specific embodiment
Below in conjunction with accompanying drawing down-hole of the present utility model stoste solar energy heating is removed wax apparatus and do following detailed description the in detail.
As shown in Figure 1, down-hole of the present utility model stoste solar energy heating is communicated with sleeve pipe 4 booster pump 2, stoste circulating tank 3 and the oil pipe except that the oil pipe sample valve 1 of wax apparatus by the stoste pipeline.The stoste that stoste circulating tank 3 internal memory oil storing tube sample valves 1 take out treats that stoste is heated mechanism heats after operating temperature, by booster pump 2 stoste in the stoste circulating tank 3 is extruded irrigating cannula 4 and promotes the wax deposition that the oil pipe temperature is removed tube inner wall.
Heating arrangements is provided with superconduction heat-exchanger rig 5 in stoste circulating tank 3, the circulation pump 6 of heating arrangements, solar energy collector 7 and superconduction heat-exchanger rig 5 are communicated with by the medium circulation pipeline.The superconductive medium pipe of superconduction heat-exchanger rig 5 annular in stoste circulating tank 3 is provided with, and the contact area of increase and stoste improves heat transfer efficiency.
Be provided with temperature pick up and control chip in the solar energy collector 7, when temperature pick up detected heat transfer medium and reaches assigned temperature, control chip was connected the power supply of circulation pump 6, and heat transfer medium is transported in the superconduction heat-exchanger rig 5.
The fluid infusion case 8 of heating arrangements and fluid infusion pump 9 are communicated with the medium circulation pipeline by pipeline.Before the operation, earlier heating arrangements is full of heat transfer medium, when the heat transfer medium of medium circulation pipeline loses, can adds in the medium circulation pipeline by the heat transfer mediums of fluid infusion pump 9 with storage in the fluid infusion case 8.
Also be provided with electrothermal furnace 10 on the heat medium circulating line of heating arrangements, under night or illumination condition of poor, use the electrothermal furnace heating.
Above-mentioned heat transfer medium can be water, superconducting fluid or other liquid state, gaseous heat-transfer medium.
Down-hole of the present utility model stoste solar energy heating remove wax apparatus reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, thereby, have good value for applications.
