The embodiment of the application provides a heating system, and the heating system can absorb heat from produced water, and provides heat for oil field oil-drawing water injection stations, transfer stations, combined stations and the like.

The produced water is also water contained in the produced liquid, the produced liquid is heated to fifty-six degrees or even higher after being produced so as to separate crude oil and water in the produced liquid, the separated water can be called produced water or sewage, and the produced water is required to be reinjected to a stratum or can be called reinjection water.

In one scenario, after the produced water is separated, the temperature is relatively high, the produced water is directly discharged into the reinjection pipe, and the produced water contains a large amount of corrosive substances, so that the reinjection pipe is severely corroded by the high-temperature corrosive substances. And the produced water is cooled to normal temperature, which will cause heat waste. The heating system of the present application may be used to absorb heat from produced water and then use the absorbed heat in systems requiring heating. Therefore, on one hand, the produced water is cooled, the reinjection pipe is protected, the corrosion degree of the produced water to the reinjection pipe can be weakened, on the other hand, the heat is recovered, the energy is saved, and the waste is changed into valuable.

As shown in fig. 1, the heating system may include a produced water tank 1, a heat collecting member 2, a hot water tank 3, a hot water pump 4, and a heat using device 5; the first water outlet of the water extraction tank 1 is connected with the first water inlet of the heat acquisition part 2 through a pipeline; the first water outlet of the heat collecting piece 2 is connected with the water inlet of the hot water tank 3 through a pipeline, the water outlet of the hot water tank 3 is connected with the water inlet of the hot water pump 4 through a pipeline, and the water outlet of the hot water pump 4 is connected with the heat utilization equipment 5 through a pipeline.

Wherein the arrows in figure 1 characterize the direction of flow of produced water in the heating system.

Wherein the produced water tank 1 is a water tank for storing produced water.

In one example, the production water tank 1 may comprise a water inlet and a plurality of water outlets, and the separated produced water flows into the production water tank 1 through the water inlet of the production water tank 1. A water outlet of the water tank 1 can be marked as a first water outlet of the water tank 1 and a water inlet of the heat collecting part 2 are connected through a pipeline.

Wherein, the heat collecting part 2 can be a water source heat pump and is used for absorbing the heat of the produced water.

In an example, the heat collecting member 2 may include a plurality of water outlets, and one water outlet of the heat collecting member 2, which may be recorded as a first water outlet of the heat collecting member 2, is connected to a water inlet of the hot water tank 3 through a pipe, so that the heat collecting member 2 conveys the absorbed hot water to the hot water tank 3 through the pipe for storage.

The first water outlet of the heat collecting element 2 is an outlet for hot water to flow to the hot water tank 3, and may be referred to as a hot water outlet.

Wherein, the hot water tank 3 is a water tank for storing hot water with higher temperature, has the function of heat preservation, and can be a steel horizontal tank with the volume of 50 cubic meters.

In one example, the water outlet of the hot water tank 3 and the water inlet of the hot water pump 4 are connected by a pipe, and the water outlet of the hot water pump 4 and the heat utilization device 5 are connected by a pipe. The hot water pump 4 may be a suction pump for pumping hot water from the hot water tank 3 and pumping the hot water to the heat using unit 5.

The heat utilization unit 5 may be a thermodynamic system of an oil field oil and water injection station, a transfer station, a united station, and the like, and may be a heating device, for example. For another example, the heat unit 5 may be a heat tracing pipeline requiring heat tracing in a production well or a water injection station, and the heat tracing pipeline is also a pipeline requiring heating to increase the fluidity of the liquid in the pipeline.

In the present embodiment, the heat unit 5 is not limited, and may be any device or system that requires heating.

As can be seen from the above, the heating system absorbs the heat of the produced water in the produced water tank 1 through the heat collecting member 2, and then stably transfers the heat to the heat using equipment 5 via the hot water tank 3 and the hot water pump 4. On the one hand, the heat recovery of the produced water is realized, the energy waste is reduced, on the other hand, the produced water is cooled, the corrosion degree of the produced water to the reinjection pipe is weakened, and the reinjection pipe is protected.

And compared with the mode that the heating furnace is used for providing heat for the heat utilization equipment 5 in the heat supply system, the method obviously can reduce the amount of flue gas discharged by the heating furnace, can weaken the pollution to the environment, reduces the development cost of the oil field to a certain extent, and is energy-saving and environment-friendly.

Since the heat of the produced water is absorbed by the heat collecting member 2 and then flows to the reinjection pipe, and is injected into the formation through the reinjection pipe, the heating system further includes a reinjection pipe 12.

Wherein, the reinjection pipe can also be called as a water injection pipe, is used for conveying produced water, and has certain corrosion resistance.

In one example, the way of the produced water after temperature reduction flowing to the return pipe 12 has various ways, one of which may be, as shown in fig. 2, another water outlet of the heat collecting member 2, which may be referred to as a second water outlet, may be connected to the return pipe 12, so that the heat of the produced water flows to the return pipe 12 via the second water outlet of the heat collecting member 2 after being absorbed.

Wherein the arrows in fig. 2 represent the flow direction of the produced water in the heating system, and the dotted lines in the heat collecting member 2 represent the path of the hot water circulation.

The second water outlet of the heat collecting piece 2 is an outlet for produced water to flow out, and is different from the first water outlet of the heat collecting piece 2.

In an example, the inside of the heat collecting element 2 may have two routes, which are respectively marked as a first route and a second route, the first route is used for hot water to pass through, and the second route is used for cooled produced water to pass through, so that the outlet of the first route is opposite to the first water outlet of the heat collecting element 2, for example, the outlet of the first route of the heat collecting element 2 is the first water outlet of the heat collecting element 2, or the outlet of the first route of the heat collecting element 2 is communicated with the first water outlet of the heat collecting element 2. And the outlet of the second path is opposite to the second water outlet of the heat collecting element 2, for example, the outlet of the second path of the heat collecting element 2 is the second water outlet of the heat collecting element 2, or the outlet of the second path of the heat collecting element 2 is communicated with the second water outlet of the heat collecting element 2.

Another way for the cooled produced water to flow to the reinjection pipe 12 may be that, as shown in fig. 3, the heat supply system further includes a production water pump 11 and a reinjection pipe 12, a second water outlet of the production water tank 1 is connected to a water inlet of the production water pump 11, and a water outlet of the production water pump 11 is connected to the reinjection pipe 12; the second water outlet of the heat collecting part 2 is connected with the first water inlet of the water collecting tank 1 through a pipeline.

Wherein, the arrow in fig. 3 represents the flowing direction of the produced water in the heating system, and the dotted line in the produced water tank 1 represents the flowing path of the produced water after temperature reduction.

As shown in fig. 3, after the high-temperature produced water enters the heat collecting element 2, the temperature is absorbed by the heat collecting element 2, and then the produced water flows back to the production water tank 1, and then enters the reinjection pipe 12 through the production water tank 1. Correspondingly, the produced water tank 1 is at least provided with two water outlets, one water outlet is used for high-temperature produced water to flow to the heat collecting part 2, and the other water outlet is used for cooled produced water to flow to the reinjection pipe 12. For example, a first water outlet of the extraction water tank 1 is connected with a first water inlet of the heat collecting member 2, and a second water outlet of the extraction water tank 1 is connected with the reinjection pipe 12 through a pipeline.

The produced water tank 1 is also provided with at least two water inlets, one water inlet is used for produced water separated from produced liquid to flow in, the other water inlet is used for produced water after cooling in the heat collection piece 2 to flow in, and the water inlet into which the produced water after cooling in the heat collection piece 2 flows can be called as a first water inlet of the produced water tank 1.

Correspondingly, the extraction water tank 1 also has at least two lines, which are respectively marked as a first line and a second line, the first line is used for flowing high-temperature extraction water, the second line is used for flowing cooled extraction water, and correspondingly, the outlet of the first line is opposite to the first water outlet of the extraction water tank 1, for example, the outlet of the first line of the extraction water tank 1 is the first water outlet of the extraction water tank 1, or the outlet of the first line of the extraction water tank 1 is communicated with the first water outlet of the extraction water tank 1. The second route is opposite to the second water outlet and the first water inlet of the extraction water tank 1, for example, the second route of the extraction water tank 1 is communicated with the first water inlet of the extraction water tank 1, an outlet of the second route of the extraction water tank 1 is communicated with the second water outlet of the extraction water tank 1, or an outlet of the second route of the extraction water tank 1 is the second water outlet of the extraction water tank 1.

In one example, in order to enable the cooled produced water to stably flow into the reinjection pipe 12, correspondingly, as shown in fig. 3, the heating system further includes a produced water pump 11, and the produced water pump 11 is installed in the pipeline between the second water outlet of the produced water tank 1 and the reinjection pipe 12. The produced water pump 11 is also a water pump and is used for pumping the produced water in the produced water tank 1, pumping the produced water into the reinjection pipe 12 and reinjecting the produced water into the stratum through the reinjection pipe 12.

In this embodiment, the specific manner of flowing the cooled produced water to the reinjection pipe 12 is not limited, and as shown in fig. 3, the heat collecting element 2 may discharge the cooled produced water to the production water tank 1, and the cooled produced water is discharged from the production water tank 1.

For some heat consumers 5 requiring a relatively high temperature, the temperature requirement of the heat consumer 5 may not be met by merely absorbing the heat of the produced water, and accordingly, as shown in fig. 4, the heating system further includes a heating furnace 6 and a gas tank 7, wherein the heating furnace 6 may be connected in any pipe between the produced water tank 1 and the heat consumer 5. For example, the heating furnace 6 may be connected at a pipe between the first water outlet of the heat collecting member 2 and the hot water tank 3. Of course, the heating furnace 6 may be connected to a pipe between the hot water tank 3 and the heat consuming device 5.

Wherein the arrows in figure 4 characterize the direction of flow of produced water in the heating system.

Here, the specific installation position of the heating furnace 6 in the heating system is not particularly limited, and may be exemplified as shown in fig. 4, between the heat collecting member 2 and the hot water tank 3.

In order to supply the heating furnace 6 with gas, correspondingly, as shown in fig. 4, the heating system further includes a gas tank 7, and an inlet end of the heating furnace 6 and the gas tank 7 are connected through a pipe so that the gas tank 7 can supply gas to the heating furnace 6. Wherein, the gas in the gas tank 7 can be liquefied natural gas, and the gas tank 7 can be a liquefied natural gas steel storage tank.

It can be seen that although the heating furnace 6 is used for secondarily heating the hot water in the heating system, compared with the heating furnace 6 which is used for supplying heat to the heat utilization equipment 5, the gas quantity of the heating furnace 6 can be obviously reduced, so that the smoke quantity discharged by the heating furnace 6 can be reduced, the pollution to the environment can be weakened, the development cost of the oil field is reduced to a certain extent, and the oil field heating system is energy-saving and environment-friendly.

In order to save energy, the hot water of the heating system can be maintained at a set temperature threshold according to the temperature required by the heat utilization equipment 5, and the hot water temperature of the heating system can be increased and reduced by adjusting the gas quantity delivered to the heating furnace 6 by the gas tank 7.

Correspondingly, as shown in fig. 5, the heating system further includes a temperature acquisition device 8 and a gas regulating valve 9; the temperature acquisition device 8 is connected to a pipeline between the heating furnace 6 and the hot water tank 3, and the temperature acquisition device 8 is used for monitoring the temperature in the heating system; a gas regulating valve 9 is installed on a pipeline between the heating furnace 6 and the gas tank 7, and the gas regulating valve 9 is used for regulating the gas quantity conveyed from the gas tank 7 to the heating furnace 6.

Wherein the arrows in figure 5 characterize the direction of flow of produced water in the heating system.

The temperature acquisition device 8 is used for measuring the temperature of the hot water flowing out of the heating furnace 6 and displaying the temperature for a technician to check.

In one example, the gas regulating valve 9 can be manually adjusted by a technician after the technician views the temperature displayed by the temperature acquisition device 8, for example, the technician finds that the temperature displayed by the temperature acquisition device 8 exceeds the temperature threshold required by the heat using equipment 5, and can adjust the gas regulating valve 9 to reduce the opening degree of the gas regulating valve 9 and reduce the gas amount delivered by the gas tank 7 to the heating furnace 6. For another example, when the technician finds that the temperature indicated by the temperature acquisition device 8 is lower than the temperature threshold required by the heat consumer 5, the technician may adjust the gas control valve 9 to increase the opening degree of the gas control valve 9 and increase the amount of gas delivered from the gas tank 7 to the heating furnace 6.

In order to automatically adjust the gas quantity delivered by the gas tank 7 to the heating furnace 6, correspondingly, as shown in fig. 6, the heating system further comprises a gas regulator 10, and the gas regulator 10 is electrically connected with the gas regulating valve 9 and the temperature collecting device 8 respectively; the gas regulator 10 is used for regulating and controlling the opening degree of the gas regulating valve 9 based on the current temperature of the heating system and the stored temperature threshold value.

Wherein the arrows in figure 6 characterize the direction of flow of produced water in the heating system.

Wherein, gas regulator 10 can be temperature-sensing electronic control unit for receive the temperature that temperature acquisition device sent, and send aperture adjustment instruction to gas governing valve 9, with the aperture of regulation and control gas governing valve 9.

In an example, after the temperature is monitored by the temperature acquisition device 8, the temperature of hot water flowing out of the heating furnace 6 can be displayed through the display window, the temperature can be sent to the gas regulator 10, a temperature threshold is stored in the gas regulator 10 in advance, the relationship between the received temperature and the temperature threshold can be compared by the gas regulator 10, if the received temperature is detected to exceed the temperature threshold, an opening degree adjusting instruction carrying opening degree reducing information can be sent to the gas regulating valve 9, and after the opening degree adjusting instruction for reducing the opening degree is received by the gas regulating valve 9, the opening degree can be reduced, so that the gas quantity conveyed by the gas tank 7 to the heating furnace 6 can be reduced. Conversely, if the gas regulator 10 detects that the received temperature is lower than the temperature threshold, an opening adjustment command carrying an increased opening may be sent to the gas regulating valve 9, and after the gas regulating valve 9 receives the opening adjustment command carrying the increased opening, the opening may be increased to increase the amount of gas delivered from the gas tank 7 to the heating furnace 6.

In order to avoid that the gas regulator 10 frequently sends an opening degree regulation instruction to the gas regulating valve 9, correspondingly, after receiving the current temperature sent by the temperature acquisition device 8, the gas regulator 10 compares the difference between the current temperature and the temperature threshold, and sends the opening degree regulation instruction to the gas regulating valve 9 if the absolute value of the difference is greater than the prestored regulation threshold, and does not send the opening degree regulation instruction to the gas regulating valve 9 if the absolute value of the difference is not greater than the prestored regulation threshold. This allows the temperature of the hot water exiting the heating furnace 6 to be stabilized at a relatively constant value.

As for the manner of adjusting the opening degree of the gas control valve 9, a possible manner may be that the gas control valve 9 adjusts a preset fixed value each time it receives an opening degree adjustment instruction. The opening degree adjusting instruction carries an adjusting direction. For example, the fixed value is adjusted in a first direction when an opening degree adjustment command for decreasing the opening degree is received, and the fixed value is adjusted in a second direction when an opening degree adjustment command for increasing the opening degree is received, wherein the first direction and the second direction are opposite.

Another possible mode may be that the opening degree adjustment instruction sent by the gas regulator 10 to the gas regulating valve 9 carries not only the adjustment direction but also an adjustment value, and after receiving the opening degree adjustment instruction, the gas regulating valve 9 may perform adjustment based on the adjustment direction and the adjustment value carried in the opening degree adjustment instruction.

The gas regulator 10 may store a corresponding relationship among an adjustment direction, an adjustment value, and a temperature difference value in advance, where the adjustment direction is determined by the positive and negative of the temperature difference value, and the adjustment value is determined by the absolute value of the temperature difference value.

The specific implementation manner of the opening adjustment of the gas regulating valve 9 is not limited in this embodiment, and the gas regulating valve 9 can automatically adjust the opening to stably adjust the temperature of the hot water flowing out of the heating furnace 6.

In an example, water discharged from the heat using device 5 may be injected into the formation through the return pipe 12 to supplement the pressure of the formation, and accordingly, as shown in fig. 7, the water outlet of the hot water pump 4 and the main water inlet of the heat using device 5 are connected through a pipe, and the main water outlet of the heat using device 5 and the second water inlet of the heat collecting member 2 are connected through a pipe.

Wherein the arrows in figure 7 characterize the direction of flow of produced water in the heating system.

As described above, the heat collecting member 2 has the first route and the second route inside, the first route supplies the hot water to flow, and the second route supplies the produced water after cooling to flow, so correspondingly, the position of the second water inlet of the heat collecting member 2 is communicated with the second route inside, so as to flow into the produced water tank 1 through the second water outlet of the heat collecting member 2.

In an example, the heat utilization equipment 5 comprises a main water inlet, a main water outlet, a plurality of heat utilization components and a plurality of branch water outlets, water with higher temperature flows in through the main water inlet, flows to each heat utilization component through each branch water outlet, then low-temperature water flowing out of each heat utilization component can flow to the heat collection component 2 through the main water outlet after being gathered, and the low-temperature water flows to the extraction water tank 1 and flows to the back injection pipe 12 through the extraction water tank 1.

Wherein, the main water outlet of the heat utilization equipment 5 can also be directly connected with the reinjection pipe 12 or connected with the production water tank 1. In this embodiment, the selection is not limited, and technicians can flexibly select the selection according to actual situations.

In one example, in order to facilitate the control of the stable flow of the produced water in the heating system and the maintenance and inspection of the heating system, correspondingly, as shown in fig. 7, a gate is installed on a pipeline between the produced water tank 1 and the heat collecting member 2, a gate is installed on a pipeline between the heat collecting member 2 and the hot water tank 3, a gate is installed on a pipeline between the hot water tank 3 and the hot water pump 4, and a gate is installed on a pipeline between the hot water pump 4 and the heat consuming device 5.

As shown in fig. 7, since the heating furnace 6 and the temperature acquisition device 8 are further arranged in the pipeline between the heat acquisition member 2 and the hot water tank 3, correspondingly, a gate is arranged on the pipeline between the heat acquisition member 2 and the heating furnace 6, a gate is arranged on the pipeline between the heating furnace 6 and the temperature acquisition device 8, and a gate is arranged on the pipeline between the temperature acquisition device 8 and the hot water tank 3.

As shown in fig. 7, a gate is also installed on the pipeline between the heat utilization device 5 and the heat collecting member 2, a gate is also installed on the pipeline between the second water outlet of the heat collecting member 2 and the first water inlet of the mining water tank 1, and a gate is also installed on the pipeline between the second water outlet of the mining water tank 1 and the mining water pump 11.

Wherein, the gate used can be a common steel gate valve.

Thus, if the heat collecting member 2 is out of order during maintenance, the gate on the pipe between the first water outlet of the producing water tank 1 and the first water inlet of the heat collecting member 2 can be closed.

As shown in fig. 7, two adjacent components in the heating system are connected by pipes, wherein the used pipes may be made of the same or different materials, for example, corrosion-resistant steel pipes, and in order to avoid heat loss of hot water in the process of flowing to the heat utilization equipment 5, each pipe is a heat preservation pipe, and the outer surface of each pipe is covered with a heat preservation material.

As shown in fig. 7, a pipe for transporting gas is provided between the gas canister 7 and the heating furnace 6, and the pipe therebetween is a hose for transporting gas.

In this embodiment, the specific form of the pipeline connected between the components is not limited, and a technician can flexibly select the specific structure and material of the pipeline according to the actually conveyed medium.
