Description

Technical Field

[0001] The invention relates to a testing device, in particular to a sulfur precipitation testing device used in the development of a high-sulfur gas field, belonging to the technical field of gas field development. Background Art

[0002] In the exploitation of high-sulfur gas fields, the raw gas and gas field water produced by high-sulfur gas fields contain a large amount of sulfur substances. Sulfur exists in many forms, such as H2S, organic sulfur, elemental sulfur, etc. Among them, sulfur substances will continuously precipitate from the produced gas during the decompression and cooling process of the produced gas, and deposit in the gathering and transportation pipeline, resulting in a significant reduction in the diameter of the gathering and transportation pipeline, and even blockage; and will also adhere to the corresponding equipment, which will affect the normal progress of mining and production, and greatly threaten the safety of production. For this reason, it is necessary to further explore the factors and conditions of sulfur precipitation to provide a prerequisite for the production of natural gas.

[0003] Prior art CN114452766A discloses "a sulfur precipitation device, a system and method for treating sulfur-containing waste gas", wherein sulfur vapor is cooled to solid sulfur for recovery to prevent the problem of liquid sulfur clogging pipelines in the subsequent treatment process, and then a multi-stage necked alkali leaching tower is used for purification. The device is simple and low in cost, and the content of hydrogen sulfide and sulfur vapor in the treated tail gas is extremely low, with good environmental benefits, thereby solving the problem of liquid sulfur clogging pipelines and direct discharge not meeting the standards in the prior art. CN102052076A discloses "a system for monitoring the composition of fluid in the wellbore of a gas field containing H2S / CO2 and its analysis method". In order to solve the above problems existing in the exploitation process of a gas field with high H2S / CO2 content, a system for monitoring the composition of fluid in the wellbore of a gas field with high H2S / CO2 content and its sampling and analysis method are invented, which solves the problem that the flow pressure and wellbore flow deposition prediction of a gas field with high H2S / CO2 content cannot be obtained due to the inability to measure, and provides a theoretical basis for the design of gas well capacity, the optimization of production parameters and the formulation of process measures.

[0024] In addition, a temperature controller may be provided in the box 1 to adjust the temperature in the box 1, thereby realizing a conditional test of sulfur precipitation in the natural gas fluid under the condition of pressure or temperature as a single variable.

[0025] Among them, the principles involved in the light source test mechanism test and the high-voltage electron microscope 17 test may include: under reduced pressure, sulfur precipitation occurs in the fluid, and the formed sulfur particles aggregate, which will cause the emitted light to diffuse and attenuate, and the transmittance gradually decreases according to the number and size of the sulfur particles, and the identification of the mutation point of the transmittance curve is realized to judge the sulfur precipitation conditions; the high-voltage electron microscope 17 test is conducive to identifying the solid particles when sulfur is precipitated, and monitoring its size change, morphology change, etc., to provide real-time reference data for sample testing.

Raise the temperature and pressure of the filtered sample to the experimental conditions, and gradually reduce the gas pressure at a certain temperature; 3. The test light source transmitter 16 in the light source test mechanism emits a laser of a certain wavelength to pass through the depressurized fluid. When the sulfur particles in the fluid begin to precipitate, the transmittance will gradually decrease; and the inflection point of the curve of the transmittance changing with pressure is the sulfur particle precipitation pressure and temperature; 4. At the same time, the formation of sulfur particles and the size of the particles in the depressurized fluid can be directly observed through a high-pressure microscope.
