[0002] In underground oil and gas exploration and development, efficient and accurate analysis of rock formation oil and gas is key to assessing reservoir potential and optimizing extraction plans. Traditional gas analysis devices typically rely on static mixing or simple mechanical agitation to achieve mixing of oil and gas with dilution gas. However, these devices have the following limitations in practical applications: existing devices often use fixed blades or passive diffusion methods (such as static mixers), which make it difficult to achieve homogenous mixing of high-viscosity oil and gas or aerosols containing droplets. Especially when processing heavy hydrocarbons or shale gas, problems such as gas stratification and droplet agglomeration can cause fluctuations in the detection signal, affecting the accuracy and efficiency of component analysis. Therefore, a rapid, multi-parameter analysis device for underground rock formation oil and gas is needed. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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

[0022] High-purity nitrogen or helium is preferred as the dilution gas used to dilute underground rock formation oil and gas. The ratio needs to be adjusted according to the analysis 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 inertized 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, and the dilution gas introduction mechanism is used to introduce dilution gas into the gas mixing mechanism through the second gas pipe 4, and complete the mixing in the gas mixing mechanism. The mixed gas is introduced into the gas analyzer 8 through the third gas pipe 7 for gas analysis, thereby completing the rapid testing of multiple parameters of underground rock formation oil and gas.

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

[0025] Specifically, if Figure 1 As shown, a pressure regulator 5 is installed on the first air pipe.

[0026] The pressure regulator 5 can be used to adjust the speed at which oil and gas flow into the underground rock formation.

[0027] Specifically, if 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 a mixing element 16, and the motor seat is fixedly mounted on the top surface of the gas analyzer 8, the bearing seat 12 is fixedly mounted on the upper end of the motor seat, and the motor 13 is arranged in the motor seat, the mixing shell 6 is fixedly mounted on the upper end of the bearing seat 12, the inner cylinder 11 is assembled in the mixing shell 6, and the output end of the motor 13 is fixedly mounted with a rotating column 15 located inside the inner cylinder 11, the outer wall of the rotating column 15 is fixedly mounted with active pressure pieces arranged equidistantly, and the inner wall of the inner cylinder 11 is symmetrically fixed with mixing elements 16 arranged equidistantly.

[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 sealed as a whole. 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 during the upward flow of underground rock formation oil and gas and dilution gas through the action of the mixing element 16 in the mixing shell 6.

[0029] Specifically, if Figure 5 As shown, the active pressing member includes an extension rod and an active pressing block 14 . One end of the extension rod is fixedly mounted on the outer wall of the rotating column 15 , and the other end of the extension rod is fixedly mounted with the active pressing block 14 .

[0030] The operation of the motor 13 drives the rotating column 15 to rotate, thereby driving the extension rod and the active pressing block 14 to rotate inside the inner cylinder 11 .

[0031] Specifically, if Figure 4As shown, the mixing element 16 includes a driven pressure block 161, a slide column 162, a fixed shell 164, a pressure leaf 165, a slide column 2 166, a slider 167 and an inward retraction rod 169. The fixed shell 164 is fixedly mounted on the outer wall of the inner cylinder 11 through a support rod. A sliding cavity is opened inside the fixed shell 164, and a sliding hole is opened on the inner end surface 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 outer end of the slider 167 is fixedly mounted with the slide column 2 166, and the slide column The outer end of the second 166 passes through the fixed shell 164 and is fixedly installed with a pressure leaf 165. A sliding groove is provided on the inner end surface of the slider 167, and one end of the retracted rod 169 is movably assembled in the sliding groove. The other end of the retracted 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 built-in 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 the active pressure block 14 and the driven pressure block 161 are both spherical.

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

[0033] The active pressure block 14 and the passive pressure block 161 are designed as spherical structures, so that the contact surface between the two is smaller, which can reduce friction loss, ensure smooth pushing action, maintain the stability of the mixing process, and prevent dilution ratio deviation due to mechanical wear.

[0034] Specifically, if Figure 4 As shown, a spring 168 is provided between the sliding post 162 and the slider 167 , and the spring 168 is sleeved on the outside of the retracted rod 169 .

[0035] When the motor 13 runs and drives the active pressure block 14 to rotate, it will contact and push the driven pressure block 161 in turn, driving the slide column 162 to move inside the fixed shell 164, and at the same time the retracted rod 169 moves in the slide hole. At this time, the spring 168 is compressed to generate elastic force to push the slider 167, the slide column 2 166 and the pressure leaf 165 to move outward. When the active pressure block 14 passes the driven pressure block 161, the spring 168 and the return spring will push the slide column 162, the driven pressure block 161 and the pressure leaf 165 to return to their original position, completing a pushing action of the pressure leaf 165. As the motor 13 runs, the active pressure block 14 continuously and repeatedly pushes the driven pressure block 161, causing the pressure leaf 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, and can also achieve a significantly efficient mixing effect.

[0036] Specifically, if Figure 4 As shown, the outer wall of the sliding column 162 is sleeved with the limiting sliding ring 163, and the limiting sliding ring 163 is movably assembled in the sliding hole.

[0037] The dual spring structure of the spring 168 and the return spring can provide effective buffering and reset functions. The limiting slip ring 163 can ensure the sliding stability of the sliding column 162, thereby improving the stability of the reciprocating motion in the mixing element 16, avoiding jamming, and making the mixing force controllable. The joint arrangement of the spring 168, the return spring and the limiting slip ring 163 enables the mixing element 16 to adapt to different gas viscosities and pressures.

[0038] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, many changes can be made in the specific implementation method and application scope. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
