Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0069] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described in some examples.

[0070] Figure 1 is a structural schematic diagram of a wax deposition effect test system in a pipeline in an embodiment of the present application.

[0071] Please refer to Figure 1 , the wax deposition effect test system 1 in the pipeline, comprising: wax precipitation control device 13, sonar detection device 12 and processing device 11.

[0072] The wax precipitation control device 13 is used to control the wax precipitation process in the pipeline 2, and the wax precipitation process is the process of wax precipitation and deposition of wax in the pipeline 2.

[0073] The wax precipitation control device 13 can be understood as follows: after the pipeline 2 is connected to the wax precipitation control device 13, the above-mentioned wax precipitation process can be carried out. After the end of the wax precipitation process, the pipeline 2 can be separated from the wax precipitation control device 13, and then the subsequent sonar detection and processing can be realized, or the subsequent sonar detection and processing can be realized without separation.

[0074] The wax precipitation process can be any processing means that can precipitate and deposit wax, and any wax precipitation control device 13 obtained based on the processing means does not deviate from the above description. Correspondingly, the time period for implementing the wax precipitation process can be understood as the wax precipitation period corresponding to the wax precipitation process, which can be any time period.

[0075] The pipeline 2 can be understood as a pipeline for wax precipitation simulation, which can be a flexible metal pipe. According to the change of test demand, pipelines with different materials, inner diameters and lengths can be selected. When the pipeline 2 is connected to the wax precipitation control device 13, its two ends can be connected through conversion joints and pipeline devices to realize the body of the fluid.

[0076] Figure 2 is a structural schematic diagram of the wax precipitation control device in an embodiment of the present application.

[0077] Please refer to Figure 2 , the wax precipitation control device 13 comprises an ambient temperature control device 134, a power source device 133, a first container 131 and an output control device.

[0078] The power source device 133 is configured to drive the wax-containing fluid in the first container 131 to enter the pipeline 2 from the first end of the pipeline 2 during the wax precipitation period corresponding to the wax precipitation process, so that the wax-containing fluid precipitates and deposits wax in the pipeline 2. It can be seen that the power source device 133 can be any device that can provide power for the fluid, and can be a horizontal flow pump or a displacement pump, so that the fluid is displaced into the pipeline 2.

[0079] Because it can provide power, the power source device 133 can be understood as a device for adjusting the flow condition of the wax precipitation process, and can specifically adjust the flow rate and flow velocity of the wax-containing fluid to meet the requirements. By changing the driving strength of the power source device 133, the flow condition of the wax precipitation process can be changed, so as to obtain the wax precipitation and wax deposition conditions under different flow conditions.

[0080] The output control device is configured to control the fluid in the pipeline 2 to be output from the second end of the pipeline 2 at a required pressure during the wax precipitation period. It can be seen that the output control device can be any device that can provide an outlet for the output of the fluid and adjust the pressure of the output fluid. It can be seen that by changing the pressure, the pressure condition of the wax precipitation process can be changed, so as to obtain the wax precipitation and wax deposition conditions under different pressure conditions.

[0081] In one embodiment, please refer to Figure 2 , the output control device can comprise a back pressure valve 135, a control pump 136, and a second container 132; the first end of the back pressure valve 135 is connected to the second end of the pipeline 2, specifically, the second end of the pipeline 2 is detachably connected to the first end of the back pressure valve 135, or is detachably connected to a pipeline connected to the first end of the back pressure valve 135, the second end of the back pressure valve 135 is communicated to the second container 132, and the control end of the back pressure valve 135 is communicated to the control pump 136. Among them, the control pump 136 can be a hand pump.

[0082] The environment temperature control device 134 is used to control the environment temperature of the pipeline 2 during the wax precipitation period, and specifically can make the environment temperature at a required temperature, that is, provide a required environment temperature to the pipeline 2. In order to realize the control of the environment temperature, in one embodiment, the pipeline 2, the first container 31, and the output control device are all in the environment temperature control device 134 during the wax precipitation period.

[0083] It can be seen that by changing the temperature, the temperature condition of the wax precipitation process can be changed, so as to obtain the wax precipitation and deposition under different temperature conditions.

[0084] The specific action principle of the wax precipitation control device 13 involved above can be described as follows:

[0085] The flow rate and / or flow velocity of the fluid are controlled by the power source device 133, so that the fluid is displaced from the first container 131 into the pipeline 2. After the fluid flows out of the pipeline 2, it flows through the back pressure valve 135 and then enters the second container 132. The back pressure valve 135 is controlled by the pump 136 to apply back pressure, so as to control the pressure. The wax in the fluid will precipitate and deposit in the pipeline 2.

[0086] Through the wax precipitation control device 13 involved above, the wax can be precipitated and deposited in the pipeline 2, and the conditions of the wax precipitation process can be further changed, so as to obtain the pipeline in which the wax is deposited, thereby providing a basis for further understanding the characteristics of the wax deposition.

[0087] The sonar detection device 12 is used to emit a first sound wave into the pipeline 2 after the end of the wax precipitation process, and to recover a second sound wave corresponding to the first sound wave. The data of the first sound wave and the second sound wave are sent to the processing device 11.

[0088] The process of emitting a sound wave and recovering a sound wave can be understood with reference to any device for detecting solids in a fluid by using a sonar. In this embodiment, it is applied to detecting the shape of the wax in the pipeline 2.

[0089] The processing device 11 is used to determine the shape of the wax deposition in the pipeline 2 according to the data of the first sound wave and the second sound wave.

[0090] Specifically, by comparing the solid shape of the pipeline 2 without wax deposition with the solid shape after the wax deposition, the shape of the wax deposition can be obtained.

[0091] It can be seen that, by means of the sonar detection device, a first sound wave is emitted into the pipeline after the wax precipitation process ends, and a second sound wave corresponding to the first sound wave is recovered, and the data of the first sound wave and the second sound wave are sent to the processing device; and the processing device is used for determining the form of wax deposition in the pipeline according to the data of the first sound wave and the second sound wave. The embodiment can obtain the form of wax deposition. Since the form can represent the characteristics of wax deposition, the embodiment can effectively obtain the characteristics of wax deposition.

[0092] In addition to obtaining the form of wax deposition, in order to accurately understand the characteristics of wax deposition, the embodiment can further obtain the amount of deposited wax. In one embodiment, the processing device 11 is further used for:

[0093] obtaining first weight data, the first weight data being the weight of the pipeline 2 without the precipitated wax before the start of the wax precipitation process; obtaining second weight data, the second weight data being the weight of the pipeline 2 containing the precipitated wax after the end of the wax precipitation process; and determining the weight of the precipitated wax in the pipeline 2 according to the first weight data and the second weight data.

[0094] The processing device 11 can also be connected with a weighing device for detecting the weight of the pipeline 2. The weight data obtained by the processing device 11 can be detected by the weighing device, so that the system can further include a weighing device for detecting the first weight data and the second weight data. For the first weight data, the detection time can be before the start of the wax precipitation process, specifically before the pipeline 2 is connected to the wax precipitation control device 13. For the second weight data, the detection time can be after the end of the wax precipitation process, specifically after the pipeline 2 is removed from the wax precipitation control device 13. Meanwhile, in the case that the detection time of the first weight data is before the start of the wax precipitation process and the detection time of the second weight data is after the end of the wax precipitation process, the specific time can be adjusted arbitrarily according to actual conditions, and is not limited to the above enumeration.

[0095] In the specific implementation process, after the test processing, the pipeline 2 can be separated from the wax precipitation control device 13, and the remaining fluid in the pipeline can be purged by a gas such as nitrogen. After the purging is completed, the weight of the pipeline 2 containing wax is detected to obtain the second weight data.

[0096] Figure 3 is a structural schematic diagram of a test system for the effect of wax deposition in a pipeline in another embodiment of the present application.

[0097] It can be seen that the wax precipitation control device 13 can be controlled by the processing device 11 or not controlled by the processing device 11. Specifically, if controlled by the processing device 11, the environmental temperature control device 134, the power source device 133, and the control pump 136 in the wax precipitation control device 13 can be connected to the processing device 11 in part or in whole, and then the processing device 11 can be specifically used for at least one of the following: setting the environmental temperature provided by the environmental temperature control device 134, setting the driving strength of the power source device 133, and setting the pressure controlled by the control pump 136.

[0098] In addition, the processing device 11 can be a single device or a collection of multiple devices. For example, the processing device 11 can include a first processing device for setting the environmental temperature control device 134, the power source device 133, and the control pump 136, and can also include a second processing device for determining the morphology. Of course, it can also be integrated into the same processing device to achieve. Similarly, the processing device for determining the morphology and the processing device for determining the amount of wax can be the same processing device or different processing devices.

[0099] In one embodiment, the processing device 11 is configured to control the wax precipitation process in the pipeline 2 by the wax precipitation control device 13. The wax precipitation process is a process in which the wax-containing fluid precipitates and deposits wax in the pipeline 2.

[0100] The power source device 133 is connected to the first end of the first container 131, and the second end of the first container 131 is used to access the first end of the pipeline 2. One end of the output control device is used to access the second end of the pipeline 2.

[0101] The power source device 133 is configured to drive the wax-containing fluid in the first container 131 to enter the pipeline 2 from the first end of the pipeline 2 according to the flow control information sent by the processing device 11, so that the wax-containing fluid precipitates and deposits wax in the pipeline 2.

[0102] The environmental temperature control device 134 is configured to control the environmental temperature of the pipeline 2, the first container 131, and the output control device.

[0103] The output control device is configured to control the fluid in the pipeline 2 to be output from the second end of the pipeline 2 at a required pressure.

[0104] In a specific implementation process, the environmental temperature control device 134 can be connected to the processing device 11 to provide the required environmental temperature for the pipeline 2, the first container 131, and the output control device according to the temperature control information sent by the processing device 11. In other ways, the environmental temperature control device 134 can not be controlled by the processing device 11.

[0105] In the implementation, the output control device is connected with the processing device 11 to control the output of the fluid in the pipeline 2 from the second end of the pipeline 2 at a required pressure according to the pressure control information sent by the processing device 11. Specifically, the output control device comprises a back pressure valve 135, a control pump 136, and a second container 132. The first end of the back pressure valve 135 is connected to the second end of the pipeline 2, the second end of the back pressure valve 135 is communicated to the second container 132, the control end of the back pressure valve 135 is communicated to the control pump 136, and the control end of the control pump 136 is connected to the processing device 11. In other modes, the output control device can also not be controlled by the processing device 11. For example, the control pump 136 can be a hand pump.

[0106] Based on the test system for the wax deposition effect in the pipeline, a process for testing using the system can be specifically listed as follows:

[0107] Step one: prepare the wax-containing fluid.

[0108] The wax-containing fluid can be specifically a wax-containing crude oil, which can be directly obtained at a mining site.

[0109] Step two: load the wax-containing fluid into the first container 131, and weigh the pipeline 2 to obtain the first weight data. The first weight data can be denoted as M1.

[0110] Step three: connect the wax deposition control device 13 to the pipeline 2, and apply back pressure through the control pump 136. After adjusting the pressure to the required pressure, proceed to step four.

[0111] Step four: set the temperature of the environmental temperature control device 134 to the required temperature. Then, the environmental temperature can be balanced under the test pressure condition.

[0112] Step five: set the flow rate generated by the power source device 133, and displace the fluid from the first container 131 into the pipeline 2 through the power source device 133, and then into the second container after passing through the back pressure valve 135.

[0113] Step six: after the above steps one to five, the wax deposition process is completed, the pipeline 2 can be removed, and the remaining fluid in the pipeline can be purged with a gas such as nitrogen. After the purging is completed, the weight of the wax-containing pipeline 2 is detected to obtain the second weight data. The second weight data can be denoted as M2.

[0114] Then, by comparing the first weight data M1 and the second weight data M2, the amount of wax deposition in the pipeline 2 can be determined.

[0115] Step seven: connect the pipeline 2 to the sonar detection device 12, and process the data of the emitted and received sound waves by the processing device 11, so as to obtain the morphology of wax deposition and obtain intuitive results.

[0116] Step eight: change the conditions, such as the flow conditions, pressure conditions, and temperature conditions mentioned above, to determine the wax deposition under different flow, pressure, and temperature conditions, and obtain the corresponding morphology and wax deposition amount of wax deposition.

[0117] The pipeline wax deposition effect test system provided by the embodiment controls the wax deposition process in the pipeline, the wax deposition process is the process of wax deposition and deposition of wax-containing fluid in the pipeline, and the wax deposition provides a basis for further understanding the characteristics of wax deposition. The application also uses the sonar detection device to emit a first sound wave into the pipeline after the end of the wax deposition process, and collects a second sound wave corresponding to the first sound wave. The data of the first sound wave and the second sound wave are sent to the processing device. The processing device is used to determine the morphology of wax deposition in the pipeline according to the data of the first sound wave and the second sound wave, and the morphology of wax deposition is obtained. Since the morphology can represent the characteristics of wax deposition, the application can effectively obtain the characteristics of wax deposition.

[0122] S103: determine the morphology of wax deposition in the pipeline according to the data of the first sound wave and the second sound wave.
