Description
Technical Field
The utility model relates to an oil well waste heat recovery is used for adding the device of medicinal cupping heating, in particular to is used for adding the controlling means of medicinal cupping based on oil well waste heat recovery.
Background
The existing continuous chemical feeding device of the oil pumping unit continuously feeds chemicals into an oil well through a wellhead so as to relieve or prevent the blockage of a shaft caused by the precipitation of crude oil asphaltene and avoid influencing the normal production of the oil well. The energy-saving continuous dosing device of the oil pumping unit is arranged in a field oil well. In winter, the chemical adding device freezes along with the liquid medicine in the temperature reduction jar, causes the chemical adding device to stop working, influences production, and at present, many oil fields at home and abroad are in the middle and later stages of development, and comprehensive water content is high, and the geothermal water volume that goes out along with going out of the well is big, and the temperature is high, if can carry out comprehensive utilization with this oil field companion hot water, will create new economic benefits, and it is also very big to the oil field energy transformation, like patent application No. 2015206287024, an oil field companion hot water's comprehensive utilization system. The system is combined to transform the existing dosing tank, and the control of the oil well waste heat recovery for the dosing tank is realized.
Disclosure of Invention
the utility model provides a controlling means for adding medicinal cupping based on oil well waste heat recovery.
The utility model discloses a realize through following technological means: control device based on oil well waste heat recovery is used for adding medicinal cupping, including adding medicinal cupping, add the medicinal cupping export and be connected with the injection mouth of well head through the pipeline that has the pump valve structure, be provided with associated hot water circulation pipeline on the well head, add the medicinal cupping and be provided with circulation companion hot water cover, circulation companion hot water sheathes in and is provided with companion hot inlet tube and companion hot return water pipe with the associated hot water circulation pipeline connection that sets up on the well head.
Further preferably, an internal temperature measuring instrument is arranged on the dosing tank, a regulating valve is arranged on the heat tracing water inlet pipeline, and the control ends of the temperature measuring instrument and the regulating valve are connected with a PID regulator through signal lines.
Further preferably, the temperature measuring instrument is a thermocouple.
And a liquid level meter is preferably arranged on the dosing tank of the dosing tank.
The utility model has the advantages that: reform transform with the medicinal cupping structure, be provided with the companion's hot circulating water of associated hot water circulation pipeline on the make full use of well head, carry out the companion's heat to adding the medicinal cupping, increased temperature control, can set for operating temperature, adjust the make full use of that has realized the energy to companion's hot water volume through the governing valve.
Description of the drawings: FIG. 1 is a schematic structural view of the present invention;
The chemical feeding device comprises a chemical feeding tank inlet 1, a circulating heat tracing water jacket 2, a liquid level meter 3, a wellhead 4, a regulating valve 5, a thermocouple 6, a heat tracing water return pipe 7, a connecting valve 8, a chemical feeding tank outlet 9, a wellhead heat tracing water circulating water inlet pipeline 10, a wellhead heat tracing water circulating water inlet pipeline 11, a pump valve structure 12, a signal line 13, a PID regulator 14 and a heat tracing water inlet pipe 15.
The following description of the present invention will be made with reference to the accompanying drawings in which:
The utility model discloses mainly be used for adding controlling means of medicinal cupping by based on oil well waste heat recovery, including adding the medicinal cupping, the export of adding the medicinal cupping is connected with the injection mouth of well head through the pipeline that has pump valve structure 12, is provided with associated hot water circulation pipeline on the well head, and associated hot water circulation pipeline includes well head associated hot water circulation inlet line 10, well head associated hot water circulation inlet line 11, and it is provided with circulation companion hot water jacket 2 to add the medicinal cupping, be provided with on the circulation companion hot water jacket 2 with the well head on the companion hot water circulation pipeline connection's that sets up companion hot inlet tube 15 and companion hot return water 7. The medicine feeding tank heat tracing water inlet pipe 15 and the heat tracing water return pipe 7 are connected with a wellhead associated hot water circulating water inlet pipeline 10 and a wellhead associated hot water circulating water inlet pipeline 11 which are arranged on the wellhead through a connecting valve 8. The heat tracing water inlet pipeline 15 is provided with an adjusting valve 5, the temperature measuring instrument is a thermocouple 6, and the control ends of the thermocouple 6 and the adjusting valve 5 are connected with a PID adjusting instrument 14 through a signal line 13.
This neotype theory of operation sets for the operating temperature who adds the medicinal cupping according to the needs of production at PID regulator 14, increases the water supply volume that accompanies the heat through regulator 14 to regulating valve 5 degree of opening when being less than the settlement temperature, and thermocouple 6 transmits the temperature signal passing signal line that adds the medicinal cupping to show at PID regulator 14, reduce the water supply volume that accompanies the heat through regulator 14 to regulating valve 5 degree of opening when being higher than the settlement temperature. The medicine adding tank is provided with a liquid level meter 3 which can measure the internal liquid level.
While the above embodiments have been described with respect to a limited number of embodiments and features, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms without departing from the spirit or scope of the invention. Accordingly, the present embodiments are to be considered as illustrative and not restrictive, and various modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
