Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of oilfield associated gas, and particularly relates to an oil well associated gas cleaning treatment device and a working method thereof. BACKGROUND

[0002] In the process of oil pipeline transportation, natural gas or crude oil is used as fuel to heat the crude oil. When associated gas produced by an oil well is used as fuel for a heating furnace near the oil well mouth, the combustion rate of hydrogen sulfide is only 14% in the combustion process, and 84% is volatilized into the atmosphere, affecting the combustion rate of natural gas. Since hydrogen sulfide is heavier than air, it flows on the surface of the earth and is easily absorbed by the human body, causing great harm to the human body. Therefore, it is necessary to remove hydrogen sulfide, water, light oil and silt from the associated gas.

[0003] In the related art, a cyclone is used to separate hydrogen sulfide, water, light oil and silt from the associated gas, and a hydrogen sulfide storage container is arranged below the cyclone to collect hydrogen sulfide, water, light oil and silt from the associated gas. However, when the light oil, water and silt containing hydrogen sulfide fall into the hydrogen sulfide storage container, the mixture of light oil, water and silt will impact the bottom wall of the hydrogen sulfide storage container, causing damage to the bottom wall of the hydrogen sulfide storage container. Moreover, during the process of falling from the cyclone to the hydrogen sulfide storage container, the mixture of light oil, water and silt will gradually accumulate at the discharge port of the bottom wall of the hydrogen sulfide storage container located at the lower end of the cyclone, which is not conducive to the discharge of the mixture of light oil, water and silt from the hydrogen sulfide storage container.

[0004] Therefore, how to avoid the impact of the mixture on the bottom wall of the hydrogen sulfide storage container to cause damage is a technical problem that needs to be solved in the field.

[0066] It is found through research that the prior art has the following disadvantages: in the related art, the hydrogen sulfide, water, light oil and silt in the associated gas are separated by a cyclone, and a hydrogen sulfide storage device is arranged below the cyclone to collect the hydrogen sulfide, water, light oil and silt in the associated gas; however, when the light oil, water and silt containing hydrogen sulfide fall to the hydrogen sulfide storage device, the mixture of the light oil, water and silt will impact the bottom wall of the hydrogen sulfide storage device, causing damage to the bottom wall of the hydrogen sulfide storage device. Moreover, in the process of falling from the cyclone to the hydrogen sulfide storage device, the mixture of the light oil, water and silt will gradually accumulate at the discharge port of the bottom wall of the hydrogen sulfide storage device located at the lower end of the cyclone, which is not conducive to the discharge of the mixture of the light oil, water and silt from the hydrogen sulfide storage device.

[0067] Therefore, how to avoid the impact of a mixture of light oil, water, and silt on the bottom wall of a hydrogen sulfide storage tank is a technical problem that urgently needs to be solved in this field.

[0068] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0069] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0070] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0071] like Figures 1 to 5 As shown, some embodiments provide an apparatus for cleaning and treating associated gas from oil wells, including:

[0072] A hydrocyclone 1 has a condenser tube 2 spirally sleeved on its outer wall. The outlet of the condenser tube 2 is connected to the inlet of the hydrocyclone 1. Associated gas enters the condenser tube 2. Under the action of centrifugal collision condensation, water and light oil in the associated gas are separated. Hydrogen sulfide dissolves in the water and light oil. The associated gas enters the hydrocyclone 1 tangentially and continues to separate. Under the centrifugal action of the hydrocyclone 1, light oil containing hydrogen sulfide, water, and silt enter the storage tank 3. In this embodiment, the storage tank 3 is a hydrogen sulfide storage tank 3. The storage tank 3 is hollow inside and is located at the lower end of the hydrocyclone 1. The storage tank 3 is suitable for collecting the solid-liquid mixture that falls into the hydrocyclone 1. When the valve below the storage tank 3 is not open, the solid-liquid mixture is temporarily stored in the storage tank 3. In this embodiment, the solid-liquid mixture refers to light oil containing hydrogen sulfide, water, and silt. A buffer assembly 4 is rotatably disposed within the storage tank 3 and positioned below the discharge port of the hydrocyclone 1. When the solid-liquid mixture separated within the hydrocyclone 1 falls towards the storage tank 3, the buffer assembly 4 rotates to mitigate the impact of the solid-liquid mixture on the bottom wall of the storage tank 3. The rotation of the buffer assembly 4 disperses the falling trajectory of the solid-liquid mixture. Through the buffer assembly 4, during the process of the solid-liquid mixture falling from the hydrocyclone 1 towards the storage tank 3, the buffer assembly 4 prevents the solid-liquid mixture from directly impacting the inner bottom wall of the storage tank 3. Furthermore, the circumferential rotation of the extension plate 43 diffuses the falling trajectory of the solid-liquid mixture, preventing the directly falling solid-liquid mixture from accumulating on the inner bottom wall of the storage tank 3.

[0073] Reference Appendix Figure 2The buffer assembly 4 comprises a fixed cylinder 41, which is internally hollow and vertically arranged inside the reservoir 3; the fixed cylinder 41 is arranged directly below the discharging port of the cyclone 1, and preferably, the outer wall of the fixed cylinder 41 is provided with a plurality of support rods in the radial direction, which are fixed to the inner bottom wall of the reservoir 3. A rotating disc 42, which is rotatably sleeved on the outer wall of the fixed cylinder 41 and is internally hollow; the outer diameter of the rotating disc 42 is smaller than the inner diameter of the discharging port of the cyclone 1, and the rotating disc 42 is spaced apart from the discharging port by a certain distance; an extension plate 43, which is arranged at an angle with the horizontal plane, a plurality of extension plates 43 are arranged circumferentially around the rotating disc 42; the extension plates 43 are arranged in the radial direction of the rotating disc 42, and adjacent extension plates 43 are arranged at equal intervals. A water inlet pipe 44, which penetrates the reservoir 3 and communicates with the fixed cylinder 41; when the associated gas flows into the cyclone 1, the water inlet pipe 44 delivers liquid into the reservoir 3, the liquid is sprayed outward through the extension plate 43, and the sprayed water flow is suitable for pushing the extension plate 43 to rotate the rotating disc 42 relative to the fixed cylinder 41. When the ambient temperature outside the cyclone 1 is not lower than zero, the water temperature delivered by the water inlet pipe 44 into the reservoir 3 is normal temperature. When the mixture of hydrogen sulfide-containing light oil, water and sand temporarily stored in the reservoir 3 is frozen and solidified, the water inlet pipe 44 delivers hot water into the reservoir 3. At this time, the associated gas stops flowing into the cyclone 1. Wherein, when the water inlet pipe 44 delivers water flow into the rotating disc 42, the water flow is suitable for rotating the extension plate 43.

[0074] Reference is made to the accompanying drawings Figure 3 The extension plate 43 is provided with a flow channel along the length direction, which communicates with the rotating disc 42; the water inlet pipe 44 delivers liquid into the rotating disc 42, which is suitable for flowing into the flow channel and being sprayed outward through the water hole 45. The upper surface of the extension plate 43 is provided with a plurality of water holes 45, which communicate with the flow channel and are directed to the inner top wall of the reservoir 3; wherein, the water flow delivered by the water inlet pipe 44 into the rotating disc 42 is suitable for being sprayed outward through the water hole 45; the water flow sprayed through the water hole 45 is suitable for rotating the rotating disc 42 relative to the fixed cylinder 41. When the extension plate 43 rotates relative to the fixed cylinder 41, the solid-liquid mixture falling from the discharging port of the cyclone 1 will impact on the upper surface of the extension plate 43, and the rotation of the extension plate 43 can avoid the long-term impact of the falling solid-liquid mixture on a certain extension plate 43, on the other hand, the rotating extension plate 43 can guide the falling solid-liquid mixture to fall away from the axis of the reservoir 3, avoiding the accumulation of the solid-liquid mixture on the inner bottom wall of the reservoir 3 below the discharging port.

[0075] Reference is made to the accompanying drawings Figure 2The air inlet of the cyclone 1 is tangentially arranged along the outer wall of the cyclone 1, and the inner diameter of the air inlet is larger than the inner diameter of the discharge port. The tangential arrangement of the air inlet enables the associated gas to rotate spirally in the cyclone 1 when the associated gas flows into the cyclone 1, so as to increase the initial flow speed of the associated gas in the cyclone 1 and improve the centrifugal separation effect.

[0076] Reference is made to the accompanying drawings Figure 3 The sidewall of the reservoir 3 is provided with a drain pipe 46, and the drain pipe 46 is provided with an electromagnetic valve adapted to control the opening and closing of the drain pipe 46. Before the associated gas flows into the cyclone 1, the water inlet pipe 44 delivers liquid into the reservoir 3 so that the liquid level is not lower than the horizontal height of the drain pipe 46. At this time, the extension plate 43 guides the falling solid-liquid mixture to play a buffering role when falling downward, avoiding the impact of solid particles in the solid-liquid mixture on the inner bottom wall of the reservoir 3.

[0077] Reference is made to the accompanying drawings Figure 3 The outer wall of the fixed cylinder 41 is provided with a temperature sensor 47 near the inner bottom wall of the reservoir 3, and the temperature sensor 47 is electrically connected with the electromagnetic valve. When the solid-liquid mixture in the reservoir 3 is not frozen and solidified, the temperature sensor 47 stops working. If the solid-liquid mixture is frozen and solidified, the water inlet pipe 44 delivers hot water into the reservoir 3, and at this time, the temperature sensor 47 starts to work. The temperature sensor 47 measures the temperature of the liquid in the reservoir 3 every 30 seconds. If the solid-liquid mixture in the reservoir 3 cannot flow into the gathering pipeline 31, the solid-liquid mixture in the reservoir 3 is in a frozen state. The water inlet pipe 44 delivers hot water into the reservoir 3 to heat and melt the solid-liquid mixture in the frozen state. The temperature sensor 47 is adapted to measure the temperature in the reservoir 3 at intervals, and the temperature sensor 47 is electrically connected with a control module. After receiving the temperature signal, the control module adjusts the opening or closing of the electromagnetic valve.

[0078] △T represents the temperature change;

[0079] T current represents the current measured temperature;

[0080] T previous represents the previous measured temperature;

[0081] Wherein, △T = T current - T previous ;

[0082] If △T > temperature threshold, the electromagnetic valve is closed;

[0083] If △T ≤ temperature threshold, the electromagnetic valve is opened, and the drain pipe 46 drains water.

[0084] In some embodiments, the temperature threshold is 2℃. Specifically,

[0085] If △T>2℃, the electromagnetic valve is closed.

[0086] If △T≤2℃, the electromagnetic valve is opened, and the drain pipe 46 drains water out.

[0087] Referring to the drawings Figure 5 In order to quickly melt the solid-liquid mixture of the frozen bottom wall of the reservoir 3, the water inlet pipe 44 delivers hot water into the reservoir 3 through the extension plate 43, and at this time the associated gas stops being delivered to the cyclone 1. The hot water exchanges heat with the solid-liquid mixture in a frozen state to melt the solid-liquid mixture, and the temperature sensor 47 measures the temperature of the liquid in the reservoir 3 every 30 seconds. If △T>2℃, it means that the difference between the current measured temperature and the previous measured temperature is greater than 2℃. Since the temperature measurement interval of the temperature sensor 47 is consistent, the volume of the hot water delivered by the water inlet pipe 44 into the reservoir 3 is consistent in the same time, and as the volume of the liquid in the reservoir 3 increases, the volume of the newly delivered hot water remains unchanged, therefore, the heating speed of the newly delivered hot water to the relatively low temperature liquid gradually slows down. If △T≤2℃, it means that the heating speed of the newly delivered hot water to the existing liquid in the reservoir 3 slows down, therefore, the drain pipe 46 needs to drain part of the liquid in the reservoir 3, and this part of the liquid refers to the liquid between the uppermost newly entered liquid and the lowermost initially existing solid-liquid mixture. Draining this part of the liquid also helps the heat of the newly entered liquid to better heat the temperature of the initially existing solid-liquid mixture.

[0088] For example, the previous measurement can be a measurement at the previous moment, and a measurement time can be set according to a specific time as the timing of the previous moment measurement.

[0089] Further, the bottom of the reservoir 3 is provided with a gathering pipeline 31, the gathering pipeline 31 is communicated with the reservoir 3 through a valve; the gathering pipeline 31 is provided with a booster pump, and when the valve is opened, the booster pump is suitable for pumping the solid-liquid mixture in the reservoir 3 into the gathering pipeline 31.

[0090] Some embodiments provide a cleaning treatment device, comprising:

[0091] The buffer assembly 4 is rotationally arranged in the reservoir 3 and arranged below the discharge port of the cyclone 1.

[0092] The buffer assembly 4 comprises: a fixed cylinder 41, which is hollow inside and vertically arranged inside the reservoir 3;

[0096] When the solid-liquid mixture separated in the cyclone 1 falls towards the storage 3, the elongated plates 43 rotate to slow down the impact of the solid-liquid mixture on the bottom wall of the storage 3.

[0097] Further, the elongated plates 43 are provided with a flow channel along the length direction, which communicates with the rotating disc 42;

[0098] The upper surface of the elongated plates 43 is provided with a plurality of water holes 45, which communicate with the flow channel and face the inner top wall of the storage 3; wherein the water flow delivered by the water inlet pipe 44 to the rotating disc 42 is adapted to be sprayed outward through the water holes 45;

[0099] The water flow sprayed through the water holes 45 is adapted to push the rotating disc 42 to rotate relative to the fixed cylinder 41.

[0100] Further, when the solid-liquid mixture in the storage 3 cannot flow into the gathering pipeline 31, the solid-liquid mixture in the storage 3 is in a frozen state;

[0101] The water inlet pipe 44 delivers hot water into the storage 3 to heat the solid-liquid mixture in the frozen state; the temperature sensor 47 is adapted to measure the temperature in the storage 3 at intervals, and the control module adjusts the opening or closing of the electromagnetic valve after receiving the temperature signal.

[0103] The associated gas flows into the cyclone 1 through the condensing pipe 2, the cyclone 1 is adapted to separate the gas in the associated gas and the solid-liquid mixture, the gas in the associated gas is discharged outward through the gas outlet pipe of the cyclone 1, and the solid-liquid mixture flows to the storage 3 through the discharge port;

[0104] When the solid-liquid mixture separated in the cyclone 1 falls towards the storage 3, the buffer assembly 4 rotates to slow down the impact of the solid-liquid mixture on the bottom wall of the storage 3;

[0105] When the buffer assembly 4 rotates, it is adapted to disperse the falling track of the solid-liquid mixture, so as to avoid the solid-liquid mixture from accumulating at the position directly below the discharge port on the inner bottom wall of the storage 3.
