[0018] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0019] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the embodiment of the present application provides a tertiary oil recovery detection method based on oil storage, which is applied in a tertiary oil recovery detection system based on oil storage, and the method includes:

[0021] S101, confirming the depth information of the oil reservoir, estimating the oil product information of the crude oil according to the depth information to obtain an estimation result, and selecting a target oil storage tank corresponding to the crude oil according to the estimation result.

[0022] According to the depth, oil reservoirs can be divided into shallow, medium-deep, deep and ultra-deep layers. The structures and proportions of various hydrocarbons in crude oil extracted at different depths are different. The processing methods of different types of crude oil are also different, and the performance of the products is also different. We should make the best use of them. After confirming the depth information of the oil reservoir, the oil product information of the crude oil is estimated according to the depth of the oil reservoir. According to the depth information, the crude oil from different oil reservoirs is transported to the corresponding oil storage tanks for storage, so as to facilitate the further processing of the crude oil products. The oil product information includes information such as oil product composition, component ratio, and compound type.

[0023] S102, confirming the tank structure of the target oil storage tank, establishing a detection scheme according to the tank structure and the oil product information, and performing corresponding detection according to the detection scheme at different input stages of the crude oil to obtain detection results, so as to determine associated oil tanks according to the detection results.

[0024] Confirm the tank structure of the oil storage tank, which includes cylindrical tanks, spherical tanks and other structural types. Establish the corresponding inspection plan for the oil storage tank according to the tank structure and oil product information. For example, confirm the inspection parts of the oil storage tank according to the structural type, and confirm the inspection plan corresponding to each inspection part. Establish inspection plans for the bottom, wall, top and accessories of the cylindrical tank. Among them, the structure of the tank top can be divided into: moment-free top tank, arch tank, cone top tank, internal floating roof tank and floating roof tank, etc. Design appropriate inspection plans for the top of different structures. Establish inspection plans for the ladder platform, manhole and connecting pipe, fire sprinkler, heat insulation and cold preservation facilities, liquid level gauge, pressure gauge and other parts of the spherical tank. In different stages of crude oil input, inspect the oil storage tank, for example: before and after crude oil input, inspect the oil storage tank. According to the established inspection plan, the oil storage tank is inspected for tank body and crude oil composition, and the storage state of the oil storage tank is adjusted according to the inspection results. For example, if an abnormality is found in the tank body inspection of an oil storage tank, the crude oil in the oil storage tank will be moved to other storage tanks for storage; if the component inspection of the oil storage tank fails, the crude oil in the oil storage tank will be removed for the next step of component processing.

[0025] S103, reserving the associated oil tank to make the associated oil tank in a sealed state, and determining whether the oil reservoir is for tertiary oil recovery;

[0026] S104: If the oil reservoir is a tertiary oil recovery, the associated oil tank is opened to store the oil from the tertiary oil recovery in the associated oil tank.

[0027] Reserving the associated tank ensures that when further storage of oil from a particular reservoir is required, there is a ready and well-conditioned container available. The associated tank is placed in a specific, pre-set state, namely a sealed state. The sealed state not only means that the inlet and outlet valves of the tank are strictly closed to prevent any external substances or air from entering, but also means that the environment inside the tank is carefully controlled to maintain the quality and stability of the oil. After reserving the associated tank in a sealed state, it is determined whether the reservoir is tertiary oil recovery. This usually involves an in-depth analysis of the geological characteristics, mining history and current mining conditions of the reservoir. If, after a comprehensive assessment, it is confirmed that the reservoir does belong to the category of tertiary oil recovery, that is, it is difficult to mine and more advanced technologies and methods are required to extract the remaining oil, then the previously reserved associated tank is opened. The opening process requires strict compliance with safety operating procedures to ensure that no leakage or safety hazards are caused when the valve is opened. After the associated tank is successfully opened, the oil from tertiary oil recovery can be safely and efficiently transported to the tank for storage through a dedicated pipeline system. Storing the oil from tertiary oil recovery in associated oil tanks not only helps protect these precious resources from pollution and damage from the external environment, but also facilitates subsequent oil processing and utilization. In addition, through effective management and monitoring, it can ensure that these oils can be taken out in a timely and accurate manner when needed to meet market demand and industrial production requirements.

[0028] In one embodiment, the target output volume provided by the transporter is confirmed, the planned output volume is determined according to the target output volume, and the output of the oil storage tank is started according to the planned output volume.

[0029] Before the transporter applies to the oil storage tank to export crude oil, it must first provide a target output volume. Since the transporter and the crude oil storage party have different measurement methods or measurement units for crude oil, the crude oil storage party may waste energy if it exports the crude oil in the oil storage tank according to the target output volume. Therefore, it is necessary to further confirm the output volume of crude oil. The crude oil storage party determines the planned output volume of the oil storage tank based on the target output volume and starts the output of the oil storage tank based on the planned output volume. For example: the measurement method of the planned output volume provided by the transporter is mass, and it is necessary to convert the crude oil volume corresponding to the mass of crude oil and use the crude oil volume as the target output volume.

[0030] In one embodiment, the volume calorific value of the crude oil is confirmed based on the oil product information, the output energy of the crude oil output by the oil storage tank to the transporter is determined based on the volume calorific value and the planned output, and the actual output is determined based on the output energy.

[0031] According to their different structures, hydrocarbons in crude oil can be roughly divided into alkanes, cycloalkanes, aromatic hydrocarbons and unsaturated hydrocarbons. The calorific value of crude oil is determined by the heat released when various combustible hydrocarbons are completely burned. Since different types of combustible hydrocarbons release different amounts of heat, the calorific value per unit volume of crude oil with different component contents is also different. According to different oil product information, some crude oil samples are extracted from oil storage tanks storing different crude oils, and the calorific value per unit volume of the crude oil, i.e., the volume calorific value, is determined according to the national standard "GB / T 384-1981 Method for Determination of Calorific Value of Petroleum Products". According to the volume calorific value of the crude oil, the crude oil energy corresponding to the above-mentioned planned output is calculated, i.e., the output energy of the crude oil output by the oil storage tank to the transporter, and the actual output of the oil storage tank is controlled according to the output energy.

[0032] A flow sensor is installed on the output pipeline of the oil storage tank, and the flow sensor is a volume flow sensor. The volume flow information of the output pipeline of the oil storage tank is obtained through the volume flow sensor. The energy flow information of the output pipeline of the oil storage tank is determined according to the volume flow information and the volume calorific value of crude oil, and the actual output is monitored according to the energy flow information.

[0033] In one embodiment, the reserve type of the oil storage tank is confirmed according to the storage tank type, and the reserve type includes an unavailable reserve and a movable reserve. If the oil storage tank is an unavailable reserve, the crude oil in the oil storage tank cannot be called, and the input pipeline switch and the output pipeline switch of the oil storage tank need to be sealed and protected to facilitate the sealed storage of the unavailable reserve. During the sealed storage period, according to the oil product information of the crude oil in the oil storage tank, a regular detection scheme for the oil product information and the type of storage tank is established (which may be referred to as the first detection scheme herein). If the oil storage tank is a movable reserve, the crude oil in the oil storage tank can be called, and the output application corresponding to the oil storage tank is reviewed, and the crude oil in the oil storage tank is transported out if the review is passed. According to the oil product information of the crude oil in the oil storage tank, a regular detection scheme for the oil product information and the type of storage tank is established (which may be referred to as the second detection scheme herein). Compared with the second detection scheme, the first detection scheme has the following differences: first, the detection cycle is different, and the detection cycle of the first detection scheme is shorter than that of the second detection scheme; second, the detection content is different, and the detection items of the first detection scheme are more than those of the second detection scheme; third, the detection standards are different, and the detection standards of the first detection scheme are higher than those of the second detection scheme; fourth, the detection timing is different, and the detection process of the first detection scheme can be carried out at any time, while the detection process of the second detection scheme needs to be carried out when the available reserve oil tanks are stopped. The tertiary oil recovery detection system based on oil storage performs automatic detection of oil tanks according to the detection schemes established for different types of oil tanks.

[0034] In one embodiment, after sending the opening instruction to the input pipeline switch of the oil storage tank, the oil storage tank receives crude oil from the oil reservoir. Since the crude oil contains water, the crude oil will be emulsified, and the water in the oil storage tank needs to be removed. Extract the crude oil sample from the crude oil transferred from the oil reservoir, and perform emulsification detection on the crude oil sample to obtain the emulsification value of the crude oil in the oil storage tank. According to the depth information of the oil reservoir, the emulsification threshold of the crude oil is confirmed, and the emulsification threshold is the optimal value of the water content of the crude oil produced by the oil reservoir. Compare the detected emulsification value with the emulsification threshold. If the emulsification value is greater than the emulsification threshold, send the closing instruction to the input pipeline switch of the oil storage tank, stop receiving the input application of the oil reservoir, and perform binary composite flooding on the oil storage tank to reduce the emulsification value of the crude oil in the oil storage tank. The binary composite flooding technology overcomes the defect of low effect of a single oil displacement agent, and utilizes the super-additive synergistic effect of the binary composite system oil displacement agent of surfactants and polymers to greatly improve the oil displacement efficiency. Injecting petroleum sulfonate, surfactant additive and polymer into crude oil in different proportions can effectively reduce the oil-water interfacial tension and improve the oil washing efficiency. Among them, the crude oil interfacial tension value is 10-2~10-1mN / m, which is low interfacial tension, and the interfacial tension below 10-3mN / m is ultra-low interfacial tension. Low oil-water interfacial tension means small adhesion work, and low oil-water interfacial tension can improve the oil washing efficiency. Binary composite flooding can not only expand the swept volume, but also improve the oil washing efficiency. It can increase the recovery rate to a greater extent than single polymer flooding. It can reduce crude oil emulsification, easy to handle, and reduce processing costs. At the same time, it can prevent alkali scaling, easy on-site operation and normal injection, and is an effective oil recovery technology.

[0035] In one embodiment, in some cases, the oil storage tank may have some faults and cannot continue to store crude oil. Therefore, according to the oil product information, the oil storage tank with the same oil product information as the crude oil in the oil storage tank is confirmed as a spare storage tank, and the input pipeline of the spare storage tank is connected to the output pipeline of the corresponding oil storage tank, and the input pipeline of the spare storage tank is also connected to the corresponding oil reservoir. If the test result of a certain oil storage tank is abnormal, for example: when the tank body of the oil storage tank is corroded and leaked, or when the gas composition in the storage tank is unqualified, the crude oil in the oil storage tank is transferred to the corresponding spare storage tank, so as to facilitate further inspection and maintenance of the oil storage tank. In addition, the oil reservoir that inputs crude oil to the oil storage tank inputs the crude oil into the spare storage tank.

[0036] In one embodiment, the crude oil in the oil storage tank flows due to collision during loading and unloading, or due to gas leakage caused by corrosion of the oil storage tank, and combustion-supporting gas, such as oxygen, enters the tank. As the combustion-supporting gas in the tank continues to accumulate, the risk of spontaneous combustion or even explosion in the oil storage tank increases. Therefore, in the embodiment of the present application, the gas composition in the tank is detected by the smoke analyzer in the oil storage tank to confirm the gas information in the tank, which includes at least oxygen (O 2 ) concentration, total hydrocarbon gas (HC) concentration, carbon monoxide (CO) concentration, carbon dioxide (CO 2 ) concentration, etc. The concentration information of each gas component contained in the above gas information is analyzed, such as Figure 2 As shown, the concentration change function corresponding to each gas component is determined, and the concentration change function is analyzed. According to the existing concentration change curve, the trend of the gas concentration change in the tank is estimated, so as to estimate the spontaneous combustion of the smoke in the oil storage tank. If it is determined according to the estimation result that at a specified time point in the future, the probability of spontaneous combustion of the smoke in the tank exceeds the range of the preset threshold, the pipeline switch of the oil storage tank is closed, and the crude oil in the oil storage tank is transferred to the spare tank until the probability of spontaneous combustion of the smoke in the oil storage tank is less than the preset threshold, then the pipeline of the oil storage tank is reopened and the transfer of crude oil to the spare tank is stopped.

[0037] In one embodiment, the tank body inspection of the oil storage tank includes routine inspection and safety inspection, wherein the inspection items of the routine inspection include but are not limited to the tank capacity of the oil storage tank, the connectivity of the input pipeline and the output pipeline, and the inspection items of the safety inspection include but are not limited to the tank temperature of the oil storage tank, the gas condition in the tank, and the corrosion condition of the tank. The first inspection scheme includes all the items of routine inspection and all the items of safety inspection, and the two tank body inspection items are carried out at the same time. The second inspection scheme includes all the items of routine inspection and some of the items of safety inspection, and because the safety inspection needs to be carried out with the tank body pipeline closed, the routine inspection cycle in the second inspection scheme is shorter than the safety inspection cycle. The selection of the safety inspection items in the second inspection scheme is determined according to the structural type of the oil storage tank and the crude oil composition. For example, for an oil storage tank with a high content of dangerous components in the crude oil composition, the safety inspection items of the second inspection scheme at least include the tank temperature and the gas condition in the tank; for an oil storage tank with a high corrosion rate of crude oil, the safety inspection items of the second inspection scheme at least include the tank temperature and the corrosion condition of the tank.

[0038] The tertiary oil recovery detection system based on oil storage monitors the detection status of the oil tank in real time to control the input and output conditions of the oil tank. For example, for a usable reserve oil tank that is under safety detection, the system will reject the input application and output application of the oil tank and send a shutdown command to the input pipeline switch and output pipeline switch of the spare tank.

[0039] In one embodiment, the output application of the transporter is analyzed to obtain the planned output of the transporter. Since the oil energy per unit volume or per unit mass of crude oil of different components is different, and there is a problem of inconsistent measurement units between each transporter and the crude oil storage party in the measurement of crude oil, therefore, rashly transporting crude oil according to the planned output in the transporter's output application will cause a certain amount of energy waste. In this application, the oil energy and oil information of the crude oil applied by the transporter are further confirmed according to the planned output, and the oil information includes the oil density of the crude oil. The crude oil output volume is obtained according to the oil density and the oil energy, and the crude oil output volume is the actual output output of the oil storage tank to the transporter. According to the above-mentioned crude oil output volume, the actual output volume flow is obtained, the output pipeline switch of the corresponding oil storage tank is turned on, and the volume flow of the oil pipeline is monitored by the flow sensor on the output pipeline, that is, the actual output of the oil storage tank is monitored.

[0040] In one embodiment, the tertiary oil recovery detection system based on petroleum storage also includes a control panel, a detection module, and a server.

[0041] Before conducting tank body inspection and crude oil composition inspection on petroleum storage tanks according to the inspection plan, the method also includes:

[0042] The employee logs in with his / her identity, confirms his / her identity information and operation instructions through the control panel, and sends the identity information and operation instructions to the server. Based on the identity information, the employee logs in to the system through the server and confirms the employee's operation authority. Based on the operation authority, the employee can start the inspection plan for the oil storage tank. Based on the employee's operation instructions on the control panel, the server confirms the employee's inspection application, which includes information such as the inspection object, inspection plan, inspection time, and inspection log. A detection instruction is generated based on the inspection application, and the detection instruction is sent to the inspection module of the oil storage tank to inspect the oil storage tank.

[0043] After the oil storage tank is tested for tank body and crude oil composition according to the test plan, the method also includes:

[0044] The server confirms the test results of the oil storage tank and sends the test results to the control panel so that the staff can view the test results. The server creates a test log for the test of the oil storage tank and updates the test results to the test log of the oil storage tank synchronously.

[0045] According to the pre-established regular inspection program in the server, the system sends inspection instructions to the inspection module, performs regular inspections on the oil storage tank, and synchronously updates the results of the regular inspections to the inspection log of the oil storage tank. Employees can modify the regular inspection program in the system through the control panel. The control panel determines the employee's modification application and sends the modification application to the server. The server modifies the regular inspection program according to the modification application, which includes modifications to the inspection cycle, the inspection items, the inspection rights, etc.

[0046] In one embodiment, the detection module includes a corrosion detection module, and the corrosion detection module includes a thickness detection module and a magnetic flux leakage detection module. When performing corrosion detection on an oil storage tank, the server determines the corrosion detection instruction according to the detection instruction, and sends the corrosion detection instruction to the corrosion detection module. The corrosion detection module starts to detect the thickness of the tank body of the oil storage tank through the thickness detection module, and sends the data of the tank body thickness to the server. The hole condition and corrosion pit condition of the bottom plate of the oil storage tank are detected by the magnetic flux leakage detection module, and the magnetic flux leakage detection module uses ultrasonic and phased array flaw detectors to check the defects or corrosion conditions of the welds. The hole condition and corrosion pit condition are sent to the server.

[0047] The detection module also includes a gas detection module and a temperature detection module. When performing gas detection on an oil storage tank, the server determines a gas detection instruction according to the detection instruction and sends the gas detection instruction to the gas detection module. The gas detection module uses an optical gas detector to detect the gas composition of the vent of the oil storage tank and sends the gas composition to the server.

[0048] The service determines the temperature detection instruction according to the detection instruction, and sends the temperature detection instruction to the temperature detection module. The temperature detection module includes an in-tank temperature module and an external temperature module. The in-tank temperature module is set inside the oil storage tank, and the external temperature module is set in the external environment of the oil storage tank. The temperature detection module starts to measure the in-tank temperature and the ambient temperature of the oil storage tank, and sends the in-tank temperature and the ambient temperature to the server.

[0049] The detection module also includes a liquid level detection module, which includes an ultrasonic transmitter module, an ultrasonic receiver module, and a data processing module. When performing liquid level detection on an oil storage tank, the server determines the liquid level detection instruction according to the detection instruction, and sends the liquid level detection instruction to the liquid level detection module. According to the liquid level detection instruction, the ultrasonic transmitter module transmits ultrasonic waves to the oil level in the oil storage tank, and the ultrasonic receiver module receives the ultrasonic waves returned from the liquid surface, and records the propagation time of the ultrasonic waves, and sends the propagation time to the data processing module.
