Then, a multi-stage necked alkali shower tower is used for purification, the device is simple and low in cost, the content of hydrogen sulfide and sulfur vapor in the treated tail gas is extremely low, and the environmental benefits are good, thereby solving the problems of liquid sulfur easily blocking the pipeline and direct discharge not meeting the standards in the prior art. CN102052076A discloses a monitoring system for the composition of H2S / CO2-containing gas field wellbore fluid and an analysis method thereof. To solve the above-mentioned problems existing in the exploitation of high-H2S / CO2-containing gas fields, a high-H2S / CO2-containing gas field wellbore fluid composition monitoring system and a sampling and analysis method thereof are invented, which solves the problem that high-H2S / CO2-containing gas fields cannot be measured to obtain flow pressure and wellbore flow deposition prediction, and provides a theoretical basis for gas well productivity design, production parameter optimization and process measure development.

Turn on the external circuit, insert the sample cylinder 20 into the restraining clamping groove 112, adjust the inclined angle of the inclined strutting rod 115 through the adjusting bolts 114, and then clamp the restraining clamping ring 116 on the two sides of the sample cylinder 20 to achieve the restraining and fixing effect;

[0079] The high-pressure electron microscope 17 is adjusted in position by rotating the connecting strut 19 so that it is located above the sample cylinder 20 and ready for testing. The high-pressure electron microscope 17 is configured to enable the identification of solid particles and to monitor their size, shape, etc.

[0080] 2. The fluid sample supply line is connected to the left side of the fluid connection pipe 15 so that the fluid is injected into the connecting hopper 102 and filtered by the first filter 1034, the second filter 1035 and the third filter 1036 in turn and then enters the experimental sample cylinder 121. At the same time, the pressure control valve 126 is opened and the pressure controller 18 is started.

[0081] The experimental cover 1212 is unscrewed and the test light source emitter 16 is started. For example, a laser is used for testing. This is advantageous for optical equipment designed to accurately measure fluid. Optical loop optimization and signal amplification can make the system more responsive, so that when sulfur particles are precipitated, the system can better confirm them.

[0082] 3. The above-mentioned test information is fed back to the control host 6. The automatic control and data collection software inside the control host 6 collects and processes information, thereby realizing computer control, and can provide user-friendly software for obtaining data and controlling the system. For example, the software has interactive icons to operate the equipment. During the experiment, data can be automatically obtained. The data is displayed by a chart and can also be stored in the form of an electronic table. There are macro commands, calculations and report generation functions. The data is displayed through the display 9.

[0083] In addition, under the action of the universal brake, the device is convenient to move and use. Commonly used items are placed in the storage drawer 4 for easy access when in use.
