Description

Technical Field

[0001] The present invention belongs to the technical field of oilfield intelligent control, and in particular relates to an oilfield intelligent control system and method based on AI algorithm. Background Art

[0002] The continuous, stable and safe operation of the oil well system in the oil field is of great significance for reducing the cost of oil field exploitation, improving the efficiency of pumping units and the output of oil wells. Especially in winter, it is very important to mix water with the produced fluid to ensure the normal exploitation of crude oil. The oil and gas metering station (referred to as the metering station) is the main station of the oil field, which concentrates the oil and gas products produced by several oil wells and measures the oil and gas production of each single well. A metering station is equipped with multiple metering rooms or oil measuring rooms, and an oil measuring room is connected to multiple oil well wellheads. The metering station is equipped with a water pump and a heating furnace. Hot water is provided by the heating furnace, and the hot water is transported to each metering room by a water pump, and then transported to each wellhead through the metering room. During this period, the hot water transported to each wellhead is controlled by the master control valve in the metering room to ensure the normal flow of the produced fluid from the wellhead.

[0003] However, after the management mode of some oil fields was changed, each metering room was divided into different units, that is, the hot water delivered to the wellhead was no longer controlled by the metering station, but was freely managed by different units. This would result in that in cold weather, each metering room would control the amount and temperature of hot water according to the produced fluid temperature observed by the metering room in order to ensure normal oil production at the wellhead it managed.

[0004] However, the water temperature observed in the metering room is delayed due to the distance between the metering station and the metering room, that is, the currently observed water temperature is inconsistent with the actual water temperature. This may cause the final water temperature to be too high, resulting in the hot water temperature in one metering room being too high, and the hot water temperature in another metering room being insufficient, resulting in water grabbing problems in the metering room, seriously affecting the efficiency of water blending in the oil field, and is not conducive to water, electricity and energy saving. Summary of the invention

[0005] The present invention provides an intelligent control method and system for oil fields based on AI algorithm, which can solve the technical problem that the hot water temperature in one metering room is too high and the hot water temperature in another metering room is not enough, thereby causing water grabbing problem in the metering room, seriously affecting the efficiency of water blending in the oil field, and being unfavorable to water saving, electricity saving and energy saving.

[0053] See also Figure 1 The embodiment of the present invention provides an oilfield intelligent control system based on AI algorithm, the system comprising:

[0054] At least one intelligent control unit, an intelligent control unit comprising:

[0055] Metering station 1 is used to centrally collect the produced fluid produced by oil well 3 and provide a hot water source;

[0056] A plurality of metering rooms 2 connected to the metering station 1;

[0057] A plurality of oil wells 3 connected to the metering room 2;

[0058] A hot water control component is arranged on the oil well 3, and is used to control the hot water and the amount of hot water entering the oil well 3;

[0059] A first temperature acquisition unit, connected to the water inlet pipe of the oil well 3, for acquiring the inlet temperature of the water entering the oil well 3;

[0060] A second temperature acquisition unit is connected to the outlet pipe of the oil well 3 and is used to acquire the temperature of the mixed liquid coming out of the oil well 3;

[0061] A comparison unit, used for comparing the hot water inlet temperature of the oil well 3 with a preset water inlet temperature, and comparing the mixed liquid temperature with a preset mixed liquid temperature;

[0062] The main control unit is connected to the first temperature acquisition unit, the second temperature acquisition unit and the hot water control component; when the inlet water temperature is lower than the preset inlet water temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the main control unit controls the opening and closing degree of the hot water control component to supply water to the oil well 3.

[0063] The system provided by the embodiment of the present invention is further explained and described below through optional embodiments.

[0064] It should be noted that the background of the system provided by the embodiment of the present invention is that the management mode of the oil field has changed. The original wellhead management of the oil field is uniformly managed by the metering station 1, that is, the water injection of the oil field is uniformly allocated by the metering station 1, and there will be no water grabbing problem, and then there will be no power and water consumption. However, after the management mode of some oil fields has changed, each metering room 2 is in charge of different units, that is, the hot water delivered to the wellhead is no longer controlled by the metering station 1, but is freely managed by different units in charge. This will lead to the fact that when the weather is cold, each metering room 2 will control the amount and temperature of hot water according to the produced liquid temperature observed by the metering room 2 in order to ensure the normal oil production of the wellhead managed by itself. However, the water temperature observed by the metering room 2 is delayed by the distance from the metering station 1 to the metering room 2, that is, the currently observed water temperature is inconsistent with the actual water temperature reached, which may cause the final water temperature to be too high, resulting in the hot water temperature of one metering room 2 being too high, and the hot water temperature of the other metering room 2 being insufficient, thereby causing the problem of water grabbing in the metering room 2, which seriously affects the efficiency of water injection in the oil field, and is not conducive to water saving, power saving and energy saving.

[0065] In other words, in the system provided by the related art, each metering room 2 has its own sub-unit, and each sub-unit is in charge of different oil wells 3 under the metering room 2. In the system provided by the embodiment of the present invention, each metering room 2 also has its own sub-unit, but no control module is set in each metering room 2, and no valve or switch that can control the entry into the wellhead is set. Instead, a hot water control component is set at each wellhead, and the hot water control component of each wellhead is connected through a master control unit of an intelligent master control unit, so that different sub-units can avoid self-control of the hot water of the wells of the metering room 2 under their control, resulting in water grabbing problems.

[0066] Furthermore, since the embodiment of the present invention is not controlled by the metering room 2, that is, the valve controlled by the metering room 2 is cancelled, the pressure drop of the pipeline is increased.

[0067] In an optional embodiment, the overall control unit is further used for:

[0068] Get the water inlet temperature of all oil wells 3;

[0069] Get the mixed liquid temperature of all oil wells 3;

[0070] Sort the mixed liquid temperature of each oil well 3 in order from small to large;

[0071] When the water inlet temperature of the oil well 3 is lower than the preset water inlet temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the hot water control component of each oil well 3 is controlled to open in the order of the mixed liquid temperature of each oil well 3 from small to large to provide hot water to the oil well 3.

[0072] After the management mode of oil well 3 is changed, the personnel of each unit in charge observe the hot water temperature and the temperature of the produced fluid of oil well 3. However, there will be time error and precision error in the way of human observation. As an example, the personnel in charge observe that the water temperature at this time is 35℃, so they open the valve to adjust the boiling water temperature. After one hour, the hot water temperature reaches 35℃. However, since the hot water observed at the outlet may not reach 35℃, the personnel in charge will continue to increase the hot water temperature. When the temperature of the hot water at the wellhead is 35℃, the temperature of the hot water coming out of the metering station 1 has reached 50℃, which will waste electricity and water energy. And if each wellhead adjusts the temperature of the hot water through the control valve of the metering room 2 under its own unit in charge in order to ensure the normal flow of its own wellhead produced fluid, there will be a rush for water, resulting in a shortage of hot water in the metering station 1, resulting in power and energy consumption.

[0073] In this embodiment, the total control unit obtains the water inlet temperature of all oil wells 3 in an intelligent control unit and the mixed liquid temperature of all oil wells 3, and sorts the mixed liquid temperature of each oil well 3 in order from small to large. The urgency of the demand for hot water of the mixed liquid of each oil well 3 can be known, and according to the urgency, it is considered which oil well 3 to provide hot water first and how much hot water to provide.

[0074] Furthermore, when the inlet water temperature of the oil well 3 is lower than the preset inlet water temperature, and the mixed liquid temperature is lower than the preset mixed liquid temperature, the hot water control element of each oil well 3 is controlled to open in the order of the mixed liquid temperature of each oil well 3 from small to large to provide hot water to the oil well 3. The above method can control all the oil wells 3 in one intelligent control unit, canceling the individual control of the oil wells 3 under the charge of each unit, avoiding water grabbing, and avoiding the waste of water, electricity, and oil and gas.

[0075] In an optional embodiment, the overall control unit is further used for:

[0076] Compare the water inlet temperature of each oil well 3 with the preset water inlet temperature to obtain a first temperature difference;

[0077] Compare the mixed liquid temperature of each oil well 3 with the preset mixed liquid temperature to obtain a second temperature difference;

[0078] When the water inlet temperature of the oil well 3 is lower than the preset water inlet temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the opening and closing degree of the hot water control component of the oil well 3 is controlled according to the first temperature difference and the second temperature difference.

[0079] By comparing the water inlet temperature of each oil well 3 with the preset water inlet temperature, the temperature difference between each oil well 3 and the preset water inlet temperature can be known, and the hot water distributed to each oil well 3 through the system can be better guaranteed to ensure that each oil well 3 works normally without causing resource waste. That is, the embodiment of the present invention not only automatically adjusts the hot water supply of each oil well 3, but also supplies water to each oil well 3 according to the situation of each oil well 3 and the urgency of water demand.

[0080] Furthermore, the water inlet temperature of each oil well 3 is compared with the preset water inlet temperature to obtain a first temperature difference; when the first temperature difference is a positive value, it means that the water inlet temperature of each oil well 3 is greater than the preset metal temperature, and water supply is not required. When the water inlet temperature of each oil well 3 is less than the preset metal temperature, it means that the water inlet temperature is far from meeting the requirement, that is, the first temperature difference is a negative value, and water supply is required to the oil well 3, and the temperature of the hot water needs to be increased.

[0081] The mixed liquid temperature of each oil well 3 is compared with the preset mixed liquid temperature to obtain the second temperature difference; when the second temperature difference is a negative value, it means that the mixed liquid temperature is less than the preset mixed liquid temperature, indicating that the mixed liquid temperature from the oil well 3 is already very low and needs to be heated by adding water. When the second temperature difference is a positive value, it means that the mixed liquid temperature is greater than the preset mixed liquid temperature, indicating that the mixed liquid temperature from the oil well 3 is acceptable and does not need to be heated.

[0082] In an optional embodiment, the overall control unit is further used for:

[0083] Sort the absolute values ​​of the first temperature differences by the order from large to small for each corresponding oil well 3;

[0084] Sort the absolute values ​​of the second temperature differences by the order from large to small for each corresponding oil well 3;

[0085] The opening and closing degree of the hot water control element of the oil well 3 is controlled in the order from large to small corresponding to the absolute values ​​of the first temperature difference and the second temperature difference.

[0086] Further, in the embodiment of the present invention, only when the first temperature difference and the second temperature difference are negative values, the oil wells 3 corresponding to the oil wells 3 are sorted in descending order according to the absolute values ​​of the first temperature difference and the second temperature difference. It can be understood that when the first temperature difference and the second temperature difference are both negative values, and the greater the absolute values ​​of the first temperature difference and the second temperature difference, the more hot water is needed, or the higher the temperature of the hot water is needed. Therefore, the oil wells 3 corresponding to the absolute values ​​of the first temperature difference and the second temperature difference are sorted in descending order, and the oil wells 3 are firstly mixed with water in descending order according to the second temperature difference. When the second temperature difference and the first stable production of the oil well 3 are both large, the oil well 3 is preferentially heated. And when the absolute values ​​of the first temperature difference and the second temperature difference are large, the opening and closing degree of the hot water control component is large, and when the absolute values ​​of the second temperature difference and the first temperature difference are small, the opening and closing degree of the hot water control component is small. It can be determined according to the needs of actual application, and the embodiment of the present invention does not limit this.

[0087] In an optional embodiment, the system further includes a third temperature acquisition unit, which is used to acquire the ambient temperature of the water inlet pipeline;

[0088] When the inlet water temperature is lower than the preset inlet water temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the main control unit controls the opening and closing degree of the hot water control component according to the ambient temperature of the inlet pipe to supply water to the oil well 3.

[0089] It is understandable that there is a certain distance between the hot water from the metering station 1 to the metering room 2 and then to the wellhead of the oil well 3, and this distance will cause temperature loss, that is, ambient temperature loss. Therefore, in order to improve the accuracy of water addition, reduce energy consumption, save water and electricity when adding water to the oil well 3, the ambient temperature of the water inlet pipeline can be obtained through the third temperature acquisition unit. When the water inlet temperature is lower than the preset water inlet temperature and the mixed liquid temperature is lower than the preset temperature of the mixed liquid, the main control unit controls the opening and closing degree of the hot water control component according to the ambient temperature of the water inlet pipeline to supply water to the oil well 3. That is, the loss of ambient temperature is taken into account for the size of the wellhead water addition temperature, which improves the accuracy of water supply and reduces resource waste.

[0090] Furthermore, when the inlet water temperature is lower than the preset inlet water temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the inlet water temperature is subtracted from the inlet pipeline ambient temperature, and the main control unit controls the opening and closing degree of the hot water control component to supply water to the oil well 3.

[0091] In an optional embodiment, the main control unit controls the opening and closing degree of the hot water control element according to the ambient temperature of the water inlet pipeline to supply water to the oil well 3, including:

[0092] When the inlet water temperature is lower than the preset inlet water temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the length of the inlet water pipeline and the ambient temperature of the inlet water pipeline are obtained.

[0093] The opening and closing degree of the hot water control element are controlled according to the length of the water inlet pipeline, the ambient temperature of the water inlet pipeline, the water inlet temperature and the mixed liquid temperature to supply water to the oil well 3.

[0094] It is understandable that hot water needs to be transported through pipelines, and the length of the pipelines will affect the temperature loss of the hot water. Therefore, by obtaining the length of the water inlet pipeline and the ambient temperature of the water inlet pipeline, the heat loss of the hot water when it is transported from the metering station 1 to the wellhead can be obtained. When adding water to the wellhead, the heat damage can be subtracted, and then the content and temperature of the water supply can be calculated.

[0095] In an optional embodiment, an intelligent master control unit further includes: a plurality of hot water pumps and a plurality of heating furnaces, the plurality of hot water pumps and the plurality of heating furnaces are located in the metering station 1 and connected to the master control unit;

[0096] The main control unit controls the opening and closing degree of the hot water control element, and supplies water to the oil well 3 including:

[0097] The main control unit controls the start and stop of the heating furnace and the hot water pump, and controls the opening and closing degree of the hot water control component to supply water to the oil well 3.

[0098] It is understandable that multiple hot water pumps and heating furnaces are provided in the metering station 1. Water is heated by the heating furnaces and the hot water is delivered to each wellhead by the hot water pumps. When multiple wellheads need to be mixed with water to provide hot water, the master control unit can control multiple heating furnaces to heat and multiple hot water pumps to deliver hot water, thereby improving water supply efficiency and reducing resource waste.

[0099] In an optional embodiment, the main control unit controls the start and stop of the heating furnace and the hot water pump according to the heating amount of the heating furnace and the power of the hot water pump, and controls the opening and closing degree of the hot water control component to supply water to the oil well 3.

[0100] It is understandable that the heating capacity of each heating furnace is different, and the power of the hot water pump is also different. The system obtains the hot water demand and allocates the heating furnace and the hot water pump according to the demand, so that the selection of the heating furnace and the hot water pump can increase the hot water temperature in the fastest time, transport the hot water to the wellhead, and control the opening and opening degree of the hot water control component to supply water to the oil well 3. In other words, when the heating furnace can provide enough hot water and the power of the hot water pump is large enough to provide hot water that meets the demand, the opening degree of the hot water control component can be increased to increase the amount of hot water provided.

[0101] Furthermore, the hot water control component provided in the embodiment of the present invention may be a multi-turn electric actuator.

[0102] On the other hand, an oilfield intelligent control method based on an AI algorithm is provided, the method is used in any of the above systems, and the method includes:

[0103] Obtain the inlet water temperature entering oil well 3;

[0104] Obtain the temperature of the mixed liquid coming out of oil well 3;

[0105] Compare the hot water inlet temperature of oil well 3 with the preset water inlet temperature, and compare the mixed liquid temperature with the preset mixed liquid temperature;

[0106] When the inlet water temperature is lower than the preset inlet water temperature and the mixed liquid temperature is lower than the preset mixed liquid temperature, the main control unit controls the opening and closing degree of the hot water control component to supply water to the oil well 3 .

[0107] The fuel cell system provided by the embodiment of the present invention has at least the following beneficial effects:

[0108] The method provided by the embodiment of the present invention can monitor the hot water temperature of each wellhead in real time, and automatically control the opening and opening degree of the hot water control component to provide hot water for each wellhead, thereby ensuring the hot water supply of each wellhead. This avoids the water grabbing phenomenon that occurs when each wellhead is manually controlled in the prior art and each wellhead is supervised by a different unit and the system control of the wellhead cannot be achieved through a metering station 1, thus saving labor and achieving the purpose of saving electricity, energy and energy.

[0109] In yet another aspect, a storage medium is provided, the storage medium including a stored computer program, wherein when the computer program is executed by a processor, the device where the storage medium is located is controlled to execute the above method.
