Description

Technical Field

[0001] This invention belongs to the field of underground rock formation oil and gas detection technology, and specifically provides a rapid multi-parameter testing device for underground rock formation oil and gas. Background Technology

[0002] In underground oil and gas exploration and development, efficient and accurate analysis of reservoir oil and gas is crucial for assessing reservoir potential and optimizing extraction strategies. Traditional gas analysis devices typically rely on static mixing or simple mechanical stirring to mix oil and gas with diluent gases. However, these methods have limitations in practical applications: existing devices often use fixed blades or passive diffusion methods (such as static mixers), making it difficult to achieve homogenized mixing of high-viscosity oil and gas or aerosols containing droplets. Especially when processing heavy hydrocarbons or shale gas, issues such as gas stratification and droplet aggregation can lead to fluctuations in the detection signal, affecting the accuracy and efficiency of component analysis. Therefore, a rapid multi-parameter analysis device for underground reservoir oil and gas is needed. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a rapid multi-parameter testing device for oil and gas in underground rock formations.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a rapid multi-parameter testing device for underground rock formation oil and gas, comprising a support frame, a first gas pipe, a second gas pipe, a third gas pipe, a gas analyzer, and a gas mixing mechanism. The gas analyzer is fixedly installed on the support frame, and the gas mixing mechanism is fixedly installed on the top surface of the gas analyzer. The outlet end of the gas mixing mechanism is connected to the inner cavity of the gas analyzer through the third gas pipe. A three-way valve is installed at the inlet end of the gas mixing mechanism.

The mixing shell is fixedly installed on the upper end of the bearing seat, the inner cylinder is assembled inside the mixing shell, and a rotating column located inside the inner cylinder is fixedly installed at the output end of the motor. Equally spaced active pressure components are fixedly installed on the outer wall of the rotating column, and equidistantly spaced mixing components are symmetrically fixedly installed on the inner wall of the inner cylinder.

[0007] Furthermore, the active pressure component includes an extension rod and an active pressure block. One end of the extension rod is fixedly installed on the outer wall of the rotating column, and the other end of the extension rod is fixedly installed with an active pressure block.

[0008] Furthermore, the mixing component includes a driven pressure block, a first sliding column, a fixed shell, a pressure blade, a second sliding column, a slider, and an inner retraction rod.

[0010] Furthermore, a limiting slip ring is sleeved on the outer wall of the sliding column, and the limiting slip ring is movably assembled in the sliding hole.

[0011] Furthermore, the active pressure block and the driven pressure block are located on the same horizontal plane, and both the active pressure block and the driven pressure block are spherical.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 5 A rapid multi-parameter testing device for underground rock formation oil and gas includes a support frame, a first gas pipe, a second gas pipe 4, a third gas pipe 7, a gas analyzer 8, and a gas mixing mechanism. The gas analyzer 8 is fixedly installed on the support frame, and the gas mixing mechanism is fixedly installed on the top surface of the gas analyzer 8. The outlet end of the gas mixing mechanism is connected to the inner cavity of the gas analyzer 8 through the third gas pipe 7. A three-way valve is installed at the inlet end of the gas mixing mechanism. The left port of the three-way valve is connected to a rock formation oil and gas introduction mechanism through the first gas pipe, and the lower port of the three-way valve is connected to a dilution gas introduction mechanism through the second gas pipe 4. A mixing component 16 is assembled inside the gas mixing mechanism, and the mixing component 16 is used to mix underground rock formation oil and gas with dilution gas.

[0022] High-purity nitrogen or helium is preferred as the dilution gas for diluting underground rock formations. The ratio needs to be adjusted according to the analytical method and sample characteristics. The key is to verify the effect of dilution on the target components through preliminary experiments and ensure that the entire process is inert to avoid contamination or reaction.

[0023] The rock formation oil and gas introduction mechanism is used to introduce underground rock formation oil and gas into the gas mixing mechanism through the first gas pipe. The dilution gas introduction mechanism is used to introduce dilution gas into the gas mixing mechanism through the second gas pipe 4. The mixing is completed in the gas mixing mechanism. The mixed gas is introduced into the gas analyzer 8 through the third gas pipe 7 for gas analysis, and the rapid testing of multiple parameters of underground rock formation oil and gas is completed.

[0024] The mixing component 16 inside the gas mixing mechanism is used to fully and efficiently mix underground rock oil and gas with dilution gas.

[0025] Specifically, such as Figure 1 As shown, a pressure regulator 5 is installed on the first trachea.

[0026] The flow rate of oil and gas in underground rock formations can be adjusted by the pressure regulator 5.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the gas mixing mechanism includes a mixing shell 6, an inner cylinder 11, a bearing seat 12, a motor 13, a motor seat, and mixing components 16. The motor seat is fixedly installed on the top surface of the gas analyzer 8, the bearing seat 12 is fixedly installed on the upper end of the motor seat, and the motor 13 is located inside the motor seat. The mixing shell 6 is fixedly installed on the upper end of the bearing seat 12, and the inner cylinder 11 is assembled inside the mixing shell 6. The output end of the motor 13 is fixedly installed with a rotating column 15 located inside the inner cylinder 11. The outer wall of the rotating column 15 is fixedly installed with equidistantly arranged active pressure components, and the inner wall of the inner cylinder 11 is symmetrically fixedly installed with equidistantly arranged mixing components 16.

[0028] The first air pipe, the second air pipe 4, and the third air pipe 7 are all connected to the inner cavity of the mixing shell 6. The mixing shell 6 is completely sealed. The first air pipe and the second air pipe 4 are connected to the lower end of the inner cavity of the mixing shell 6, and the third air pipe 7 is connected to the upper end of the inner cavity of the mixing shell 6. The mixing work is completed by the mixing component 16 inside the mixing shell 6 during the upward flow of underground rock oil and gas and dilution gas.

[0029] Specifically, such as Figure 5 As shown, the active pressure component includes an extension rod and an active pressure block 14. One end of the extension rod is fixedly installed on the outer wall of the rotating column 15, and the other end of the extension rod is fixedly installed with the active pressure block 14.

[0030] The operation of motor 13 drives the rotating column 15 to rotate, which in turn drives the extension rod and the active pressure block 14 to rotate inside the inner cylinder 11.

[0031] Specifically, such as Figure 4As shown, the mixing component 16 includes a driven pressure block 161, a first sliding column 162, a fixed shell 164, a pressure blade 165, a second sliding column 166, a slider 167, and an inner retraction rod 169. The fixed shell 164 is fixedly installed on the outer wall of the inner cylinder 11 by a support rod. A sliding cavity is opened inside the fixed shell 164, and a sliding hole is opened on the inner end face of the fixed shell 164. The slider 167 is movably assembled in the sliding cavity, and a return spring is provided between the outer end of the slider 167 and the inner wall of the sliding cavity. The second sliding column 166 is fixedly installed on the outer end of the slider 167, and the second sliding column 166... The outer end of the second 166 passes through the fixed shell 164 and is fixedly installed with the pressure blade 165. The inner end face of the slider 167 is provided with a sliding groove, and one end of the inner retracting rod 169 is movably assembled in the sliding groove. The other end of the inner retracting rod 169 is fixedly installed with a sliding column 162. One end of the sliding column 162 is movably assembled in the sliding hole, and the other end of the sliding column 162 passes through the inner cylinder 11 and is fixedly installed with a driven pressure block 161. The active pressure block 14 and the driven pressure block 161 are located on the same horizontal plane, and both the active pressure block 14 and the driven pressure block 161 are spherical.

[0032] A groove is provided on the inner wall of the built-in cylinder 11, and the driven pressure block 161 is located in the groove.

[0033] The active pressure block 14 and the driven pressure block 161 are designed with a spherical structure, which reduces the contact area when they come into contact, thereby reducing frictional loss, ensuring smooth pressing action, maintaining the stability of the mixing process, and preventing dilution ratio deviation caused by mechanical wear.

[0034] Specifically, such as Figure 4 As shown, a spring 168 is provided between the sliding column 162 and the slider 167, and the spring 168 is sleeved on the outside of the inner retraction rod 169.

[0035] When the motor 13 runs and drives the active pressure block 14 to rotate, it will sequentially contact and push the driven pressure block 161, causing the sliding column 162 to move into the fixed shell 164. At the same time, the inner retraction rod 169 moves in the sliding hole. At this time, the spring 168 is compressed and generates elastic force to push the slider 167, the sliding column 166 and the pressure blade 165 outward. After the active pressure block 14 passes the driven pressure block 161, under the action of the spring 168 and the return spring, it will push the sliding column 162, the driven pressure block 161 and the pressure blade 165 to reset, completing one pushing action of the pressure blade 165. As the motor 13 runs, the active pressure block 14 continuously pushes the driven pressure block 161, causing the pressure blade 165 to repeatedly complete the pushing and resetting actions, which can form turbulence in the mixing shell 6, significantly improving the gas mixing efficiency. Especially for high viscosity oil and gas or aerosols containing droplets, it can also achieve a significantly efficient mixing effect.

[0036] Specifically, such as Figure 4 As shown, a limiting slip ring 163 is sleeved on the outer wall of the sliding column 162, and the limiting slip ring 163 is movably assembled in the sliding hole.

[0037] The dual-spring structure, consisting of spring 168 and a return spring, provides effective buffering and reset functions. The limiting slip ring 163 ensures the stability of the sliding column 162, thereby improving the stability of the reciprocating motion within the mixing component 16, preventing jamming, and making the mixing force controllable. The combined arrangement of spring 168, return spring, and limiting slip ring 163 allows the mixing component 16 to adapt to different gas viscosities and pressures.

[0038] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.
