Description

Technical Field

[0001] This utility model relates to the field of oil and gas production and development technology, specifically to a water sampling device for sulfur-containing gas wells. Background Technology

[0002] In natural gas extraction, regular water sampling and analysis are crucial for understanding reservoir properties and production dynamics. However, because the hydrogen sulfide content in gas field water is hundreds of times higher than in natural gas, high concentrations of sulfur-containing gases can escape near the sampling port when taking water samples from sulfur-containing wells. In such cases, wearing breathing apparatus is mandatory. Although wearing breathing apparatus prevents inhalation of sulfur-containing gases, contact with high concentrations of hydrogen sulfide gas or hydrogen sulfide-containing gas field water can still cause chronic harm through the skin. Furthermore, the release and leakage of hydrogen sulfide can severely pollute the surrounding environment. Utility Model Content

[0003] To address the technical problem of sulfur-containing gas escaping near the sampling port when taking water samples from sulfur-containing gas wells, this utility model provides a sulfur-containing gas well water sampling device that can prevent sulfur-containing gas from escaping during sampling, thereby avoiding harm to the health and safety of operators and the environment caused by sulfur-containing gas.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a sampling device for sulfur-containing gas well water samples, comprising: a gas-liquid separator, which is provided with a sampling interface, a liquid phase output port and a gas phase output port; a sampling bottle connected to the liquid phase output port; and an absorption container for storing desulfurizing agent, which is provided with an absorption interface and a discharge interface, wherein the absorption interface is connected to the gas phase output port; wherein the absorption interface can input the gas inside into the desulfurizing agent stored in the absorption container.

[0006] The present invention provides a sulfur-containing gas well water sample sampling device, comprising a gas-liquid separator, a sampling bottle, and an absorption container. The gas-liquid separator is provided with a sampling interface, a liquid phase output port, and a gas phase output port. The sampling bottle is connected to the liquid phase output port. The absorption container is used to store desulfurizing agent and is provided with an absorption interface and a discharge interface. The absorption interface is connected to the gas phase output port. In use, the sampling interface is connected to the corresponding sampling port on the gas well gathering and transportation process. By operating the opening of the sampling control valve, under the action of the internal pressure of the gathering and transportation process pipeline, the liquid in the pipe enters the gas-liquid separator, so as to separate the liquid phase and gas phase of the water sample through the gas-liquid separator. The liquid enters the sampling bottle for collection and sampling, and avoids liquid splashing. The gas is transported through the gas phase output port to the absorption interface of the absorption container, so as to input the gas phase into the desulfurizing agent stored in the absorption container. Then, the desulfurizing agent absorbs and removes the sulfides contained in the gas, thereby preventing the sulfur-containing gas from escaping. The remaining gas is discharged from the exhaust port of the absorption container.

[0007] Therefore, the sulfur-containing gas well water sampling device provided by this utility model can prevent the sulfur-containing gas from escaping during sampling, thereby avoiding the harm of sulfur-containing gas to the health and safety of operators and the environment.

[0008] In an optional embodiment of this application, the gas-liquid separator includes: a central tube, one end of which is connected to the sampling interface and the other end of which is connected to the liquid phase output port; a separator housing, sleeved outside the central tube, forming a gas phase cavity with the outer wall of the central tube; and a first sampling connector, disposed on the separator housing, for sealing connection to the sampling bottle, and provided with a gas connection port; wherein the gas phase output port is disposed on the separator housing, and both the gas phase output port and the gas connection port are connected to the gas phase cavity, so as to ensure that the gas-liquid separator effectively separates the liquid phase and the gas phase while facilitating the collection of the separated water sample.

[0011] In an optional embodiment of this application, the diversion housing is further provided with a displacement interface, which is used to connect to the pump gas assembly so that after sampling is completed, displacement gas is input to the gas-liquid splitter through the displacement interface, thereby displacing the residual gas in the gas-liquid splitter and pumping it into the absorption container for absorption and removal treatment, further preventing the direct emission of sulfur-containing gas into the environment.

[0012] In an optional embodiment of this application, a pumping assembly is also included to facilitate the direct input of displacement gas to the gas-liquid splitter.

[0014] In an optional embodiment of this application, a one-way valve is provided between the air pump and the replacement interface to prevent the gas output from the gas-liquid splitter from escaping from the air pump.

[0015] In an optional embodiment of this application, the displacement interface is connected to a pressure gauge to facilitate observation of the gas pressure inside the gas-liquid splitter, providing data support for the control of the sampling flow rate.

[0016] In an optional embodiment of this application, an aerator is provided at the bottom of the absorption container, and the aerator is connected to the absorption interface to ensure that the gas output from the gas-liquid separator can fully contact the desulfurizing agent, thereby ensuring the absorption and removal effect of sulfides.

[0017] In an optional embodiment of this application, the aerator includes an aeration pipe, which is placed flat at the bottom of the absorption container, and the side wall of the aeration pipe is provided with multiple exhaust holes to ensure that the aerator can disperse and output sulfur-containing gas.

[0018] In an optional embodiment of this application, a safety valve is connected between the absorption port and the discharge port. When the gas pressure at the absorption port exceeds a set threshold, the safety valve connects the absorption port and the discharge port to prevent the pressure in the absorption container from becoming too high and to ensure the safety of the absorption container.

[0019] In an optional embodiment of this application, an exhaust gas detector is also included. The exhaust gas detector is connected to the emission port and is used to detect the sulfur content of the gas discharged from the emission port, so as to detect in real time whether the gas discharged by the device meets the standard, and to facilitate corresponding treatment when the sulfur content of the discharged gas exceeds the standard.

[0020] In an optional embodiment of this application, the exhaust gas detector includes: a detection box having a detection inlet and a detection outlet, the detection inlet being connected to the emission outlet; and a hydrogen sulfide gas detector installed on the detection box, with the detection probe located inside the cavity of the detection box.

[0021] In an optional embodiment of this application, a mounting groove is provided on one side of the detection box, and a mounting pressure plate is adapted to be installed in the mounting groove. The mounting pressure plate can slide along the length direction of the mounting groove. The detection box is equipped with a clamping knob, so as to push the mounting pressure plate to move by rotating the clamping knob, thereby fixing the hydrogen sulfide gas detector in the mounting groove, so as to facilitate the installation and maintenance of the hydrogen sulfide gas detector.

[0022] In an optional embodiment of this application, a sampling control valve is further included, which is connected to the sampling interface to facilitate adjustment of the sampling flow rate.

The gas-liquid separator is equipped with a sampling interface, a liquid phase output port, and a gas phase output port. The sampling bottle is connected to the liquid phase output port. The absorption container is used to store desulfurizing agent and is equipped with an absorption interface and a discharge interface. The absorption interface is connected to the gas phase output port. In use, the sampling interface is connected to the corresponding sampling port on the gas well gathering and transportation process. By operating the opening of the sampling control valve, under the pressure inside the gathering and transportation pipeline, the liquid in the pipe enters the gas-liquid separator, so that the liquid can be sampled by the gas-liquid separator. The water sample is separated into liquid and gas phases. The liquid enters the sampling bottle for collection, thus avoiding liquid splashing. The gas is delivered through the gas phase outlet to the absorption port of the absorption container, where it is introduced into the desulfurizing agent stored in the absorption container.

[0052] Combination Figure 4 and Figure 5 The gas-liquid separator 10 includes: a central tube 101, one end of which is connected to the sampling interface 11 and the other end of which is connected to the liquid phase output port 12; a separator housing 102, which is sleeved on the central tube 101 and forms a gas phase cavity 103 with the outer wall of the central tube 101; a first sampling connector 104, which is disposed on the separator housing 102 and is used to seal and connect the sampling bottle 20, and is provided with a gas connection port 105; wherein, the gas phase output port 13 is disposed on the separator housing 102, and both the gas phase output port 13 and the gas connection port 105 are connected to the gas phase cavity 103, so as to ensure that the gas-liquid separator 10 effectively separates the liquid phase and the gas phase, while facilitating the collection of the separated water sample.

[0053] Specifically, the upper and lower ends of the diversion housing 102 are provided with mounting slots 106, which can be locked with the mounting box 70 to facilitate the installation of the gas-liquid diverter 10.

[0054] In this embodiment, the gas-liquid splitter 10 further includes a second sampling connector 107, which is disposed on the splitter housing 102 and coaxially disposed outside the first sampling connector 104. Thus, this embodiment provides two specifications of sampling interfaces, enabling the gas-liquid splitter 10 to connect to two different specifications of sampling bottles 20, thereby improving the applicability of the device.

[0055] Based on this, the diversion housing 102 is also provided with a displacement interface 108, which is used to connect to the pump assembly so that after sampling, displacement gas can be input to the gas-liquid splitter 10 through the displacement interface 108 to replace the sulfur-containing gas remaining in the gas-liquid splitter 10 and pump it into the absorption container 30 for absorption and removal treatment, further preventing the sulfur-containing gas from being directly emitted into the environment.

[0056] It is understood that this embodiment also includes a pumping assembly to facilitate the direct input of replacement gas into the gas-liquid splitter 10.

[0057] Specifically, the gas pumping assembly includes a gas pump 41, which can input gas into the gas phase chamber 103 via the displacement port 108, so as to input displacement gas into the gas-liquid splitter 10. Generally speaking, a manual pump is used as the gas pump 41, which does not require additional driving energy, thereby improving the convenience of use and the safety of operation of the device.

[0058] It should be understood that a one-way valve 42 is provided between the air pump 41 and the replacement interface 108 to prevent the gas output from the gas-liquid splitter 10 from escaping from the air pump 41.

[0059] Generally, the displacement interface 108 is connected to a pressure gauge 109 to observe the gas pressure inside the gas-liquid splitter 10, providing data support for the control of the sampling flow rate.

[0060] Combination Figure 6 An aerator 33 is provided at the bottom of the absorption container 30. The aerator 33 is connected to the absorption interface 31 to ensure that the gas output from the gas-liquid separator 10 can fully contact the desulfurizing agent and ensure the absorption and removal effect of hydrogen sulfide.

[0061] In this embodiment, the aerator 33 includes an aeration pipe, which is placed flat at the bottom of the absorption container 30, and the side wall of the aeration pipe is provided with multiple exhaust holes to ensure that the aerator 33 can disperse and output sulfur-containing gas.

[0062] Typically, a safety valve 34 is connected between the absorption port 31 and the discharge port 32. When the gas pressure at the absorption port 31 exceeds a set threshold, the safety valve 34 connects the absorption port 31 and the discharge port 32 to prevent the pressure in the absorption container 30 from becoming too high and to ensure the safety of the absorption container 30.

[0063] Recombined Figures 1-3 This embodiment also includes an exhaust gas detector 50, which is connected to the emission port 32 and is used to detect the sulfur content of the gas discharged from the emission port 32, so as to detect in real time whether the gas discharged by the device meets the standard, and facilitate corresponding treatment when the sulfur content of the discharged gas exceeds the standard.

[0064] Combination Figure 7 and Figure 8 The exhaust gas detector 50 includes: a detection box 51, which is provided with a detection inlet 52 and a detection outlet 53, wherein the detection inlet 52 is connected to the emission outlet 32; and a hydrogen sulfide gas detector 54, which is installed on the detection box 51, with the detection probe located in the cavity of the detection box 51.

[0065] In this embodiment, a mounting groove 55 is provided on one side of the detection box 51, and a mounting pressure plate 56 is adapted to be installed in the mounting groove 55. The mounting pressure plate 56 can slide along the length direction of the mounting groove 55. The detection box 51 is equipped with a clamping knob 57, so that by rotating the clamping knob 57, the mounting pressure plate 56 can be moved to fix the hydrogen sulfide gas detector 54 in the mounting groove 55, so as to facilitate the installation and maintenance of the hydrogen sulfide gas detector 54.

[0066] Combination Figure 2 and Figure 3 This embodiment also includes a sampling control valve 60, which is connected to the sampling interface 11 to facilitate the adjustment of the sampling flow rate.

[0067] In addition, this embodiment also includes an installation housing 70, in which the absorption container 30 is installed and the gas-liquid separator 10 is installed on the installation housing 70 to provide protection for the absorption container 30 through the installation housing 70.

[0068] Specifically, the mounting box 70 is equipped with a handle 71 to facilitate carrying the mounting box and improve the portability of the sampling device.

[0069] In summary, the sulfur-containing gas well water sampling device provided in this embodiment includes a gas-liquid separator 10, a sampling bottle 20, an absorption container 30, a pump assembly, and a tail gas detector 50. The gas-liquid separator 10 is provided with a sampling interface 11, a liquid phase output port 12, and a gas phase output port 13. The sampling bottle 20 is connected to the liquid phase output port 12. The absorption container 30 is used to store desulfurizing agent and is provided with an absorption interface 31 and a discharge interface 32. The absorption interface 31 is connected to the gas phase output port 13. The pump assembly can input replacement gas into the inner cavity of the gas-liquid separator 10. The tail gas detector 50 is connected to the discharge interface 32.

[0070] Before use, first check that the amount of desulfurizing agent (complexed iron) is normal. Connect the sampling bottle 20 to the liquid phase output port 12 and tighten it to ensure a seal. Ensure all connections are properly sealed, then connect the sampling quick connector connected to the sampling interface 11 to the matching interface at the sampling port in the process flow. Lead the detection emission port 53 to a more distant downwind direction, install the portable hydrogen sulfide detector on the detection box 51, and tighten the clamping knob 57. Then turn on the device to put the hydrogen sulfide detector into working condition.

[0071] During sampling, the sampling control valve 60 at the process end is slowly opened, allowing the gas field water to reach the central pipe 101 of the gas-liquid separator 10 via the connecting pipeline, and then enter the sampling bottle 20. The escaped gas phase enters the absorption port 31 of the absorption container 30 through the gas phase output port 13 of the gas-liquid separator 10. After being dispersed by the gas aerator 33, the gas phase reacts with the absorption liquid, and hydrogen sulfide is absorbed. The treated gas phase is then detected by the hydrogen sulfide detector and released through the detection and discharge port 53.

[0072] During sampling, the liquid level in sampling bottle 20 should be continuously observed. When the appropriate sampling volume is reached, the sampling control valve 60 at the process end should be closed immediately. Then, the air pump 41 should be driven to push the residual gas in the connecting pipe and gas-liquid separator 10 into the absorption container 30 to achieve a displacement effect. Finally, the sampling bottle 20 should be removed from the gas-liquid separator 10, and the inner and outer caps of the sampling bottle 20 should be replaced to seal the sampling bottle 20.

[0073] During the sampling process, pay attention to the changes in the pressure gauge reading and the liquid level in sampling bottle 20. The pressure should not exceed 5 kPa, and the sample should be taken at a suitable distance from the bottle opening. When the pressure inside sampling bottle 20 is too high, safety valve 34 will open, and the gas will flow directly to the detection and discharge port 53. At this time, the hydrogen sulfide detector will alarm, and the device needs to be re-inspected. Sampling can only continue after the abnormality has been eliminated.

[0074] Additionally, when the absorption effect of the desulfurizing agent decreases and the gas at emission port 53 fails to meet the emission requirements, the hydrogen sulfide detector will also alarm. In this case, the absorbent liquid must be replaced before continued use. When replacing the absorbent liquid, simply remove the cap assembly of the absorption container 30, pull it out of the mounting box 70, and replace the rich solution with a new lean absorbent liquid.

[0075] It should be noted that the entire device is housed in a portable mounting box 70. After sampling is completed, the quick connector at the sampling end and its connecting pipes, as well as the venting connecting pipe at the rear end, can be stored in the reserved space of the box for easy relocation and use.

[0076] In summary, the sulfur-containing gas well water sampling device provided in this embodiment can prevent the sulfur-containing gas from escaping during sampling, thereby avoiding harm to the health and safety of operators and the environment caused by the sulfur-containing gas.

[0077] The sampling device provided in this embodiment is movable, offering flexibility in operation position and method; the sampling bottle interface can accommodate multiple specifications, making it suitable for various sampling bottles; the device itself is not pressurized or is slightly positively pressurized (absorbing liquid resistance), resulting in low operational risk; it utilizes available resources (reagents and recovery) from existing exhaust gas treatment devices, requiring minimal additional investment; and it features safety measures such as pressure observation, overpressure relief, and outlet sulfur detection, ensuring high safety.

[0078] It should be noted that although this embodiment can achieve the effect of removing toxic gases by sealing the sampling and absorbing hydrogen sulfide, it is still necessary to wear an air respirator for protection during the operation due to mandatory requirements for prevention and safety.

[0079] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
