Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gas detection, in particular to a gas analysis device for petroleum exploration. Background Art
[0002] In the process of oil exploration and production, it is crucial to accurately analyze the composition and concentration of the measured gas. These gases not only contain hydrocarbon components in oil and natural gas, such as methane, ethane, propane, etc., but may also contain non-hydrocarbon gases such as hydrogen, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, etc. The presence and concentration of these gases directly affect the quality and safety of oil and natural gas, so accurate detection and analysis of them is of great practical significance.
[0003] In exploration wells, due to changes in formation pressure, the measured gas often sprays out from the wellhead at extremely high speed and impact force, which poses a great challenge to the direct collection and analysis of these gases. Traditional gas sampling methods are not only difficult to implement in this case, but also pose a safety hazard, because high-speed gas spraying may cause equipment damage, sample contamination or personal injury. At the same time, the measured gas often carries more impurity particles, which can cause blockage of the detection pipeline or instrument, resulting in large errors in the analysis data.

[0020] like Figures 4 to 6As shown, a fixed filter plate 206 is arranged in the detection chamber, and the inner wall of the inner cylinder 203 is fixedly connected in the fixed filter plate 206, and a plurality of filter holes are arranged on the fixed filter plate 206, and the fixed filter plate 206 is arranged near the connection between the delivery pipe 102 and the inner cylinder 203, so that the measured gas in the delivery pipe 102 can be filtered through the fixed filter plate 206 when entering the inner cylinder 203, and a shaking spring 207 is fixedly installed on the fixed filter plate 206, and a shaking filter plate 208 is fixedly installed on the other end of the shaking spring 207, and a plurality of capillary pores are arranged on the shaking filter plate 208, and the capillary pores are smaller than the filter pores on the fixed filter plate 206, so The shaking filter plate 208 is slidably connected to the inner cylinder 203. The shaking filter plate 208 is arranged at one end away from the top cover 204. The fixed filter plate 206 and the shaking filter plate 208 are used to filter and clean large particles in the measured gas. When the measured gas continuously enters the inner cylinder 203, the measured gas will leave the large particles. When the measured gas impacts the shaking filter plate 208, the shaking filter plate 208 will continuously shake on the inner cylinder 203 through the shaking spring 207. This is to allow the shaking filter plate 208 to slow down the movement speed of the exhaust gas while constantly shaking, so that the exhaust gas can stay in the inner cylinder 203 for a longer time.
[0021] like Figures 4 to 6 As shown, a plurality of cleaning screws 305 are rotatably mounted on one end of the bottom cylinder 202 away from the inner cylinder 203, a pulley 303 is fixedly mounted on one end of the cleaning screw 305 away from the inner cylinder 203, the pulley 303 is arranged outside the detection chamber, a belt 304 is arranged on the pulley 303, and is used to synchronize the rotation of all the cleaning screws 305, a cleaning motor 302 is also fixedly mounted on the bottom cylinder 202, a cleaning screw 305 is fixedly mounted on the output shaft of the cleaning motor 302, and a cleaning device is also slidably mounted in the bottom cylinder 202 306, the cleaning device 306 is arranged in the detection chamber, and the cleaning device 306 is connected to the cleaning screw 305 by threads. The cleaning device 306 is also provided with a plurality of hard brushes for cleaning the inner surface of the inner cylinder 203. When the cleaning screw 305 rotates, it drives the cleaning device 306 to move away from the bottom cylinder 202. When the cleaning device 306 moves to a predetermined position, the cleaning device 306 will contact the shaking filter plate 208. This is to clean the capillaries on the shaking filter plate 208 so that the shaking filter plate 208 can work normally.
[0022] like Figures 1 to 3As shown, an air outlet pipe 210 is fixedly installed on the inner tube 203.

A variety of purifiers are arranged in the purification module 211, so that the measured gas can be purified by the purifier after entering the purification module 211. The purification module 211 is fixedly connected to the pipeline rack 103.
[0023] Working principle: When the device is in use, the delivery pipe 102 is connected to the external measured gas pipeline, and then the measured gas is allowed to enter the inner tube 203, and then the measured gas will enter the detection chamber. When the measured gas continues to enter the detection chamber, the measured gas will leave large particles behind, and when the measured gas impacts the shaking filter plate 208, the shaking filter plate 208 will continuously shake on the inner tube 203 through the shaking spring 207. This is to allow the shaking filter plate 208 to slow down the movement speed of the measured gas while constantly shaking, so that the measured gas can stay in the inner tube 203 for a longer time, thereby improving the detection time and detection accuracy of the detection module 209. After passing through the fixed filter plate 206 and the shaking filter plate 208, the measured gas will enter the purification module 211 through the outlet pipe 210, and then the measured gas will be purified and discharged through the purification module 211.
[0024] After the use of this device is finished, the cleaning motor 302 can be started to rotate with the cleaning screw 305. When the cleaning screw 305 rotates, the cleaning device 306 is driven to move away from the bottom tube 202. When the cleaning device 306 moves to a predetermined position, the cleaning device 306 will contact the shaking filter plate 208. This is to clean the pores on the shaking filter plate 208 so that the shaking filter plate 208 can return to normal working state and prevent the pores on the shaking filter plate 208 from being blocked.
