Description

Technical Field

[0001] The present invention belongs to the technical field of associated gas in oil fields, and particularly relates to a cleaning treatment device for associated gas in oil wells and its working method. Background Art

[0002] In the process of transporting crude oil through oil field pipelines, natural gas or crude oil is used as fuel to heat the crude oil. The natural gas is all associated gas produced from oil wells. When the associated gas is used as fuel for the heating furnace near the oil well head, during the combustion process, the combustion rate of hydrogen sulfide is only 14%, and 84% volatilizes into the atmosphere, affecting the combustion rate of natural gas. Since hydrogen sulfide is heavier than air and flows on the ground surface, it is easily absorbed by people, causing great harm to the human body. Therefore, it is necessary to remove hydrogen sulfide, water, light oil, and sediment from the associated gas.

[0003] In the related art, a hydrocyclone is used to separate hydrogen sulfide, water, light oil, and sediment from the associated gas, and a hydrogen sulfide storage tank is arranged below the hydrocyclone to collect hydrogen sulfide, water, light oil, and sediment in the associated gas; however, when the light oil containing hydrogen sulfide, water, and sediment falls towards the hydrogen sulfide storage tank, the mixture of light oil, water, and sediment will impact the bottom wall of the hydrogen sulfide storage tank, causing damage to the inner bottom wall of the hydrogen sulfide storage tank. Moreover, during the process of the mixture of light oil, water, and sediment falling from the hydrocyclone towards the hydrogen sulfide storage tank, it will gradually accumulate at the feed opening at the lower end of the hydrocyclone on the bottom wall of the hydrogen sulfide storage tank, which is not conducive to the hydrogen sulfide storage tank discharging the mixture of light oil, water, and sediment.

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

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0066] It has been found through research that the disadvantages of the prior art are as follows: In the related art, a hydrocyclone is used to separate hydrogen sulfide, water, light oil, and sediment in associated gas, and a hydrogen sulfide storage is provided below the hydrocyclone to collect hydrogen sulfide, water, light oil, and sediment in the associated gas; however, when the light oil containing hydrogen sulfide, water, and sediment falls towards the hydrogen sulfide storage, the mixture of light oil, water, and sediment will impact the bottom wall of the hydrogen sulfide storage, causing damage to the inner bottom wall of the hydrogen sulfide storage. Moreover, during the process of the mixture of light oil, water, and sediment falling from the hydrocyclone towards the hydrogen sulfide storage, it will gradually accumulate at the discharge port of the bottom wall of the hydrogen sulfide storage located at the lower end of the hydrocyclone, which is not conducive to the hydrogen sulfide storage discharging the mixture of light oil, water, and sediment.

[0067] Therefore, how to prevent the mixture of light oil, water and mud from impacting the inner bottom wall of the hydrogen sulfide storage tank is a technical problem that urgently needs to be solved in the field.

[0068] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0069] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0070] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0071] like Figures 1 to 5 As shown, some embodiments provide an oil well associated gas cleaning treatment device, comprising:

[0072] The cyclone 1 has a condenser 2 spirally sleeved on its outer wall, and the air outlet of the condenser 2 is connected to the air inlet of the cyclone 1; the associated gas enters the condenser 2, and under the action of centrifugal collision condensation, water and light oil in the associated gas are separated, and hydrogen sulfide is dissolved in the water and light oil. The associated gas enters the cyclone 1 tangentially and continues to be separated. Under the centrifugal action of the cyclone 1, the light oil and water containing hydrogen sulfide, as well as mud and sand enter the storage 3. The storage 3 described in this embodiment is a hydrogen sulfide storage 3; the storage 3 is hollow inside and is arranged at the lower end of the cyclone 1. The storage 3 is suitable for collecting the solid-liquid mixture dropped from the cyclone 1; when the valve below the storage 3 is not opened, the solid-liquid mixture is temporarily stored in the storage 3. The solid-liquid mixture described in this embodiment refers to the light oil, water and mud containing hydrogen sulfide. The buffer assembly 4 is rotatably arranged in the storage 3 and is arranged below the discharge port of the cyclone 1; wherein, when the solid-liquid mixture separated in the cyclone 1 falls into 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; when the buffer assembly 4 rotates, it is suitable for dispersing the falling trajectory of the solid-liquid mixture. Through the arrangement of the buffer assembly 4, in the process of the solid-liquid mixture falling from the cyclone 1 to the storage 3, the buffer assembly 4 can prevent the solid-liquid mixture from directly falling and hitting the inner bottom wall of the storage 3; moreover, the extension plate 43 rotates circumferentially, which can disperse the falling trajectory of the solid-liquid mixture and prevent the directly falling solid-liquid mixture from accumulating on the inner bottom wall of the storage 3.

[0073] Reference Figure 2, the buffer assembly 4 includes: a fixed cylinder 41, which is hollow inside and vertically arranged inside the reservoir 3; the fixed cylinder 41 is arranged directly below the discharge port of the cyclone 1. Preferably, a plurality of support rods are arranged on the outer wall of the fixed cylinder 41 in the radial direction, and the support rods are fixed on the inner bottom wall of the reservoir 3. A turntable 42, which is rotatably sleeved on the upper end of the outer wall of the fixed cylinder 41 and is hollow inside; the outer diameter of the turntable 42 is smaller than the inner diameter of the discharge port of the cyclone 1, and there is a certain distance between the turntable 42 and the discharge port. An extension plate 43, which has an angle with the horizontal plane, and a plurality of the extension plates 43 are arranged circumferentially around the turntable 42; the extension plate 43 is arranged radially along the turntable 42, and adjacent extension plates 43 are arranged at equal intervals. A water inlet pipe 44, which penetrates through the reservoir 3 and is communicated with the fixed cylinder 41; when the associated gas flows into the cyclone 1, the water inlet pipe 44 conveys liquid into the reservoir 3, and the liquid is sprayed outwards through the extension plate 43, and the sprayed water flow is suitable for pushing the extension plate 43 so that the turntable 42 rotates relative to the fixed cylinder 41. When the ambient temperature outside the cyclone 1 is not lower than zero degree Celsius, the water temperature conveyed into the reservoir 3 by the water inlet pipe 44 is normal temperature. When the mixture of light oil containing hydrogen sulfide, water and sediment temporarily stored in the reservoir 3 freezes and solidifies, the water inlet pipe 44 conveys hot water into the reservoir 3. At this time, the associated gas stops flowing into the cyclone 1 continuously. Among them, when the water inlet pipe 44 conveys water flow into the turntable 42, the water flow is suitable for pushing the extension plate 43 to rotate.

[0074] Reference appendix Figure 3 , a flow channel is opened along the length direction of the extension plate 43, and the flow channel is communicated with the turntable 42; the water inlet pipe 44 conveys liquid into the turntable 42, and the liquid is suitable for flowing into the flow channel and spraying outwards through the water holes 45. A plurality of water holes 45 are opened on the upper surface of the extension plate 43, the water holes 45 are communicated with the flow channel and face the inner top wall of the reservoir 3; among them, the water flow conveyed by the water inlet pipe 44 to the turntable 42 is suitable for spraying outwards through the water holes 45; when the water flow is sprayed through the water holes 45, it is suitable for pushing the turntable 42 to rotate 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 discharge port of the cyclone 1 will impact on the upper surface of the extension plate 43. On the one hand, the rotation of the extension plate 43 can prevent the falling solid-liquid mixture from impacting a certain extension plate 43 for a long time. On the other hand, the rotating extension plate 43 can guide the falling solid-liquid mixture to fall in the direction away from the axis of the reservoir 3, avoiding the accumulation of the solid-liquid mixture at the lower part of the inner bottom wall of the reservoir 3 under the discharge port.

[0075] Reference appendix Figure 2, the 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 that of the blanking port. The tangential arrangement of the air inlet enables the associated gas to rotate spirally within the cyclone 1 when flowing into the cyclone 1, so as to increase the initial flow rate of the associated gas within the cyclone 1 and improve the centrifugal separation effect.

[0076] Reference appendix Figure 3 , a drain pipe 46 is provided on the side wall of the storage tank 3, and a solenoid valve is arranged on the drain pipe 46, and the solenoid valve is 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 conveys liquid into the storage tank 3 to make the water level not lower than the horizontal height of the drain pipe 46. At this time, the extension plate 43 guides the falling solid-liquid mixture, and the liquid level plays a buffering role when falling downward, avoiding the solid particles in the solid-liquid mixture from impacting the inner bottom wall of the storage tank 3.

[0077] Reference appendix Figure 3 , a temperature sensor 47 is arranged on the outer wall of the fixed cylinder 41 near the inner bottom wall of the storage tank 3, and the temperature sensor 47 is electrically connected to the solenoid valve. When the solid-liquid mixture in the storage tank 3 does not freeze and solidify, the temperature sensor 47 stops working; if the solid-liquid mixture freezes and solidifies, the water inlet pipe 44 conveys hot water into the storage tank 3. At this time, the temperature sensor 47 starts to work, and the temperature sensor 47 measures the temperature of the liquid in the storage tank 3 every 30 s. If the solid-liquid mixture in the storage tank 3 cannot flow into the gathering and transportation pipeline 31, the solid-liquid mixture inside the storage tank 3 is in a frozen state; the water inlet pipe 44 conveys hot water into the storage tank 3 to heat and melt the frozen solid-liquid mixture; the temperature sensor 47 is adapted to measure the temperature inside the storage tank 3 at regular intervals, and the temperature sensor 47 is electrically connected to the control module, and the control module receives the temperature signal and then adjusts the solenoid valve to open or close.

[0078] △T represents the temperature change;

[0079] T current represents the currently measured temperature;

[0080] T previous represents the temperature measured in the previous time;

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

[0082] If △T > the temperature threshold, then the solenoid valve closes;

[0083] If △T ≤ the temperature threshold, then the solenoid valve opens, and the drain pipe 46 discharges water outward.

[0084] In some embodiments, the temperature threshold is set to 2°C. Specifically,

[0085] if △T > 2°C, the solenoid valve closes;

[0086] if △T ≤ 2°C, the solenoid valve opens, and the drain pipe 46 drains water outwards.

[0087] Refer to the appendix Figure 5 To quickly melt the solid-liquid mixture frozen on the inner bottom wall of the storage tank 3, the water inlet pipe 44 conveys hot water into the storage tank 3 through the extension plate 43. At this time, the associated gas stops being conveyed to the cyclone 1. The hot water exchanges heat with the frozen solid-liquid mixture to melt the solid-liquid mixture, and the temperature sensor 47 measures the temperature of the liquid in the storage tank 3 every 30 seconds. If △T > 2°C, it means that the temperature difference between the currently measured temperature and the previous measured temperature is greater than 2°C. Since the temperature measurement interval of the temperature sensor 47 is consistent, that is, the volume of hot water conveyed into the storage tank 3 by the water inlet pipe 44 within the same time is the same. As the volume of the liquid in the storage tank 3 increases while the volume of the newly conveyed hot water remains unchanged, the heating rate of the newly conveyed hot water to the relatively lower-temperature liquid gradually slows down. If △T ≤ 2°C, it means that the heating rate of the newly conveyed hot water to the liquid already existing in the storage tank 3 becomes slower. Therefore, the drain pipe 46 needs to drain part of the liquid in the storage tank 3. This part of the liquid refers to the liquid in the middle part between the newly entered liquid at the top and the initial solid-liquid mixture at the bottom. Draining this part of the liquid also helps the heat of the newly entered liquid to better raise the temperature of the initially existing solid-liquid mixture.

[0088] Exemplarily, the previous measurement can be the measurement at the previous moment, and a measurement time can be set according to the specific time as the opportunity for the previous moment measurement.

[0089] Furthermore, a gathering pipeline 31 is provided at the bottom of the storage tank 3. The gathering pipeline 31 is communicated with the storage tank 3 through a valve; a booster pump is provided on the gathering pipeline 31. When the valve is opened, the booster pump is adapted to pump the solid-liquid mixture in the storage tank 3 into the gathering pipeline 31.

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

[0091] A buffer assembly 4, which is rotatably arranged in the storage tank 3 and is arranged below the discharge port of the cyclone 1;

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

[0093] A turntable 42, which is rotatably sleeved on the upper end of the outer wall of the fixed cylinder 41 and is hollow inside;

[0094] An extension plate 43 is provided with an angle between it and the horizontal plane, and a plurality of the extension plates 43 are arranged circumferentially around the turntable 42;

[0095] A water inlet pipe 44 penetrates through the storage 3 and is communicated with the fixed cylinder 41;

[0096] Wherein, when the solid-liquid mixture separated in the hydrocyclone 1 falls towards the storage 3, the extension plate 43 rotates to slow down the impact of the solid-liquid mixture on the bottom wall of the storage 3.

[0097] Further, a flow channel is formed along the length direction of the extension plate 43, and the flow channel is communicated with the turntable 42;

[0098] A plurality of water holes 45 are formed on the upper surface of the extension plate 43, the water holes 45 are communicated with the flow channel and face the inner top wall of the storage 3; wherein, the water flow conveyed by the water inlet pipe 44 to the turntable 42 is adapted to be ejected outward through the water holes 45;

[0099] When the water flow is ejected through the water holes 45, it is adapted to push the turntable 42 to rotate relative to the fixed cylinder 41.

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

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

[0102] Some embodiments provide a working method of a cleaning treatment device, and the working method includes:

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

[0104] When the solid-liquid mixture separated in the hydrocyclone 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 trajectory of the solid-liquid mixture to prevent the solid-liquid mixture from accumulating directly below the blanking port on the inner bottom wall of the storage 3.
