[0049] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The step numbers in the following embodiments are provided for ease of description only and do not limit the order of the steps. The order of execution of the steps in the embodiments can be adaptively adjusted based on the understanding of those skilled in the art.

[0050] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0051] In the following description, the terms "first\second\third" are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0052] Unless otherwise defined, all technical and scientific terms used in the embodiments of the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the embodiments of the present invention are for the purpose of describing the embodiments of the present invention only and are not intended to limit the present invention.

[0053] Before further explaining the embodiments of the present invention in detail, the nouns and terms involved in the embodiments of the present invention are explained. The nouns and terms involved in the embodiments of the present invention are subject to the following interpretations.

[0054] Insoluble organic matter (IOM) refers to organic matter in sedimentary rocks that cannot be dissolved by conventional organic solvents. It serves as the "raw material reservoir" for oil and gas formation. IOM is primarily composed of complex macromolecules left over from the degradation of biological remains such as plants and algae during burial, and is the precursor to kerogen.

[0055] Kerogen refers to dispersed organic matter in sedimentary rocks that, after evolution through geological processes (such as temperature and pressure), becomes insoluble in alkali, non-oxidizing strong acids, and non-polar organic solvents. It is the direct parent material for the formation of petroleum and natural gas. Kerogen can be divided into Types I, II, and III depending on its source, with different types corresponding to different potentials for oil and gas generation.

[0056] Hydrates (natural gas hydrates), commonly known as "combustible ice," are solid compounds composed of water molecules forming a cage-like crystal structure that encapsulates natural gas (primarily methane). Hydrates are stable at low temperatures (e.g., 0-10°C) and high pressures (e.g., in deep-sea or permafrost environments), making them an important unconventional energy source.

[0057] Hydrocarbons: Organic compounds composed solely of carbon and hydrogen, they are the primary components of petroleum and natural gas; they include methane, liquid crude oil, and solid asphalt. Their various forms are determined by the length of their carbon chains and their molecular structure.

[0058] In the relevant technology, the methods for preparing and enriching sedimentary insoluble organic matter at home and abroad mostly rely on manual or semi-mechanized operations, extracting and separating sediments under high temperature conditions. The operation is cumbersome and involves highly toxic and corrosive substances such as hydrochloric acid and hydrofluoric acid, which pose a serious threat to the personal safety of operators and the environment. At the same time, high temperature conditions can accelerate the digestion reaction of mineral impurities in sediments, but will lead to the destruction of the macromolecular structure of insoluble organic matter and cause the light hydrocarbon components contained therein to be lost, thereby affecting the accuracy of the analysis results.

[0059] In view of this, an embodiment of the present invention provides a sedimentation insoluble organic matter enrichment device and system, which uses low-temperature automated sample processing and organic matter separation and enrichment technology to digest mineral impurities in insoluble organic matter, extract and separate insoluble organic macromolecules; reduces the destruction of the organic matter molecular structure through low-temperature enrichment, better ensures the original composition of the extract, and improves the accuracy of the extraction and analysis results; adopts multiple reaction cycle control to dissolve impurities and extract insoluble organic matter, reduces manpower participation, reduces labor costs, and improves enrichment efficiency.

[0060] Please refer to Figure 1 , Figure 1 The embodiment of the present invention provides an optional structural diagram of an enrichment device for depositing insoluble organic matter; Figure 1As can be seen from the content, an embodiment of the present invention provides an enrichment device for deposited insoluble organic matter, the system includes a low-temperature enrichment subsystem and a computer control and acquisition subsystem, wherein:

[0061] The low-temperature enrichment subsystem is used to enrich and extract the sample to be processed according to the control instructions and the reaction solution to obtain the target sediment and waste gas and waste liquid, and neutralize the waste gas and waste liquid;

[0062] The computer control and acquisition subsystem is used to collect data from the low-temperature enrichment subsystem, determine the system operation data, generate control instructions based on the system operation data, and issue alarm prompts to the low-temperature enrichment subsystem based on the system operation data.

[0063] The embodiment of the present invention shows an enrichment device for depositing insoluble organic matter, which is provided with a low-temperature enrichment subsystem and a computer control and acquisition subsystem. The sample to be processed that needs to be enriched with insoluble organic matter is enriched and processed in the low-temperature enrichment subsystem. The low-temperature enrichment subsystem provides a constant low-temperature environment and reacts the sample to be processed in this constant low-temperature environment; during the reaction process, the low-temperature enrichment subsystem automatically adds a reaction solution to the sample to be processed to dissolve impurities in the sample to be processed, and then automatically removes the waste liquid after the reaction and extracts the waste gas generated by the reaction; and repeats the above-mentioned addition and discharge operations. The low-temperature enrichment subsystem completes the enrichment and extraction of insoluble organic matter until the number of cycles set in the computer control and acquisition subsystem is met; the computer control and acquisition subsystem collects data during the operation of the low-temperature enrichment subsystem in real time, analyzes the collected data, monitors the operating status of the low-temperature enrichment subsystem in real time, and issues an alarm when the low-temperature enrichment subsystem has an abnormal operation; at the same time, the automatic operation of the low-temperature enrichment subsystem is controlled according to the collected data; users can set or adjust the sample enrichment process through the computer control and acquisition subsystem to adapt to the enrichment requirements of different types of insoluble organic matter.

[0064] In some embodiments, the low-temperature enrichment subsystem can provide a constant temperature environment through refrigeration equipment, such as fans, compressors, etc.; it can also provide a constant temperature environment through low-temperature circulating liquid, such as liquid nitrogen, etc.; this embodiment of the present invention is not limited.

[0065] See also Figure 2 In some embodiments, the low-temperature enrichment subsystem includes a low-temperature automatic control module, a sample automatic reaction module, a liquid addition and discharge module, and a discharge processing module; wherein,

[0066] Low temperature automatic control module, used to perform constant temperature control on the sample automatic reaction module according to preset temperature and control instructions;

[0067] The sample automatic reaction module is used to perform low-temperature enrichment treatment on the sample to be processed to obtain the target sediment;

[0068] The liquid addition and discharge module is used to perform liquid addition and discharge operations on the sample automatic reaction module according to preset reaction parameters and control instructions; wherein the preset reaction parameters include the reaction solution type and set amount;

[0069] The emission treatment module is used to neutralize waste gas and waste liquid; wherein the waste gas and waste liquid are generated by the sample automatic reaction module.

[0070] In some embodiments, the low-temperature enrichment subsystem is composed of a low-temperature automatic control module, a sample automatic reaction module, a liquid addition and discharge module, and a discharge processing module. The low-temperature automatic module can be set in the reaction area of the sample automatic reaction module, and a low-temperature reaction environment is provided for the reaction area of the sample automatic reaction module through a refrigeration device, and the temperature of the reaction area is collected in real time through sensors and other devices to maintain a constant low-temperature environment; in this embodiment, a TMS series ultra-low temperature constant temperature circulation device is used to achieve high-precision constant temperature through a fully enclosed magnetic pump and stirring to provide a stable and uniform low-temperature field for the reaction area; the sample automatic reaction module provides a reaction container, and the sample to be processed and the reaction acid react in the reaction container to remove non-organic impurities in the sample to be processed. At the same time, the sample automatic reaction module automatically filters out the reaction waste liquid for the next time reaction; under the control of the upper computer, the liquid addition and discharge module quantitatively and regularly delivers the reaction solution to the reaction vessel of the sample automatic reaction module; at the same time, the reaction waste liquid generated in the reaction vessel is extracted; in this embodiment, the liquid addition and discharge module can also set the interval operation time and the number of operations, and automatically add and discharge liquid to the reaction vessel according to the set parameters; in this embodiment, a peristaltic pump is used for liquid addition and discharge operations, which can achieve a speed regulation accuracy of 0.1RPM, which can improve the utilization rate of the reaction solution and the efficiency of sample enrichment and extraction; at the same time, the liquid addition and discharge module uses a perfluoro rubber hose to connect the reaction vessel of the sample automatic reaction module to achieve completely closed transportation of the reaction solution, thereby increasing the service life of the entire device; the emission treatment module is connected to the sample automatic reaction module through a hose, and neutralizes the waste gas and waste liquid extracted and output from the sample automatic reaction module to reduce the pollution of the sample enrichment treatment to the environment.

[0071] Please refer to Figure 3 In some embodiments, the sample automatic reaction module includes a reactor, a filter membrane, a magnetic stirring device and a piston assembly; wherein,

[0072] A reactor, used for performing low-temperature pickling treatment on the sample to be treated;

[0073] A magnetic stirring device, used to stir and mix the sample to be processed and the reaction solution to obtain a reaction mixture;

[0074] A filter membrane, used to filter the reaction mixture to obtain a waste liquid;

[0075] The piston assembly is used to drive the filter membrane to move and transport the reaction solution and / or waste liquid.

[0076] In some embodiments, the sample automatic reaction module is composed of a reactor, a filter membrane, a magnetic stirring device and a piston assembly. The reactor is a reaction container for enriching and extracting the sample to be treated. Since the sample to be treated is enriched and extracted using an acid solution, such as hydrochloric acid and / or hydrofluoric acid, the inner tank of the reactor can be made of 304 stainless steel, and the outer shell of the reactor is coated with an anti-corrosion spray coating to reduce the corrosion of the reactor by the acid solution used in the reaction. The magnetic stirring device is arranged at the bottom of the reactor to stir the reaction solution and the sample to be treated, thereby increasing the contact area between the reaction solution and the sample to be treated and improving the reaction efficiency. At the same time, the accumulated heat generated in the sample to be treated due to the reaction is released by stirring, thereby forming a stable and uniform low-temperature atmosphere, reducing the loss of volatile organic matter due to high temperature, improving the enrichment efficiency, reducing sample loss, and thereby improving the accuracy of subsequent component analysis. The filter membrane adopts a filter membrane with strong hydrophobicity, high retention rate, excellent chemical tolerance and thermal stability, good strength and resistance to positive and reverse pressure shocks. The filter membrane filters the reaction mixture to separate the reaction waste liquid and the sample, replacing the traditional centrifugal method for separating the sample and the reaction waste liquid, thereby improving the efficiency and effect of separation and enrichment; the piston assembly is arranged in the reactor and moves up and down along the reactor; in this embodiment, the piston assembly is used to seal the reactor, thereby reducing the leakage of toxic waste gas generated during the reaction process; at the same time, the up and down movement of the piston assembly drives the filter membrane arranged at the bottom of the assembly to move, thereby collecting the reaction solution and the organic sample at the bottom of the reactor, and the reaction waste liquid is filtered through the filter membrane and permeates above the piston to become a single-phase waste liquid, thereby trapping the organic matter in the reactor and then extracting it from the addition and discharge module to the discharge treatment module for further treatment; then, during the next liquid addition, the reaction solution is used to backwash the filter membrane to reduce the residual organic matter on the filter membrane and improve the enrichment and extraction effect; through the piston assembly and the filter membrane, the bottom discharge method in the traditional method is changed to the top discharge method, which can reduce the thickness of the bottom of the reactor, thereby better performing magnetic stirring and increasing the stirring intensity.

[0077] See also Figure 4 In some embodiments, the sample automatic reaction module may perform the following method, which includes steps S401 to S403:

[0078] Step S401: Obtain a sample to be processed, perform low-temperature pickling on the sample to be processed to obtain a reaction sample; and record the current reaction number and compare the current reaction number with a preset number;

[0079] Step S402: If the current number of reactions is less than the preset number, the reaction sample is used as a sample to be processed, and the process returns to the low-temperature acid washing step to obtain a reaction sample; until the current number of reactions is greater than or equal to the preset number;

[0080] Step S403: If the current number of reactions is greater than or equal to the preset number, the reaction sample is neutralized to obtain a neutralized sample, and the neutralized sample is washed to obtain a target sediment.

[0081] In step S401 of some embodiments, the organic sample to be processed is added to the reactor, and then the host computer starts the liquid addition and drainage module, drives the peristaltic pump to transport a preset acid solution into the reactor, and starts the magnetic stirring device to stir and mix the organic sample and the acid solution to improve the reaction efficiency; the host computer detects the operating time of the magnetic stirring device in real time, and after detecting that the operating time of the magnetic stirring device reaches the preset stirring time, temporarily stops the operation of the magnetic stirring device, filters the reacted solution to obtain waste liquid, and drains the filtered waste liquid; the host computer detects the drainage time, and after the drainage time reaches the set time, closes the drainage valve and records the completion of an organic sample reaction; then, the host computer compares the recorded number of reactions with the preset number in the system to determine the next operation.

[0082] In step S402 of some embodiments, if it is determined through comparison that the recorded number of reactions is less than the preset number, it means that the enrichment and extraction processing of the organic matter sample to be processed is not completed, and the filtered organic matter sample needs to continue to be pickled. The host computer repeats the operation in step S401 according to the set program; until the recorded number of reactions is greater than or equal to the preset number.

[0083] In step S403 of some embodiments, if it is determined through comparison that the recorded number of reactions is greater than or equal to the preset number, it means that the enrichment and extraction processing of the organic matter sample to be processed has been completed, and the upper computer starts the liquid addition and drainage module, drives the peristaltic pump to transport alkaline solution into the reactor to neutralize the acid remaining on the surface of the organic matter that has completed the enrichment and extraction in the reactor, and then opens the drain valve to discharge the neutralized solution, and transports distilled water into the reactor through the peristaltic pump to wash the organic matter that has completed the enrichment and extraction to obtain the target sediment.

[0087] In some embodiments, a certain degree of sealing of the reactor is achieved by a piston assembly. The diameter of the piston in the piston assembly is the same as the diameter of the reactor, and a through hole is provided in the center of the piston for setting a delivery pipeline for the reaction solution and / or reaction waste liquid. The delivery pipeline can be connected to the drainage module and the discharge treatment module through a hose; one end of the piston rod is connected to the bottom of the piston, and the other end of the piston rod is provided with a filter membrane. A through hole is also provided in the piston rod, which is connected to the through hole of the piston and is used to set a delivery pipeline to achieve the delivery of the reaction solution to the reaction container and the extraction of the waste liquid obtained by filtering the filter membrane; the piston assembly can move up and down along the reactor in the reactor. When the piston assembly moves downward, the organic sample and reaction solution in the reactor gather at the bottom of the reactor and are filtered by the filter membrane provided at the bottom of the piston assembly to obtain a single-phase waste liquid, which is then extracted through the piston and the delivery pipeline provided in the piston assembly.

The peristaltic pump can set the liquid addition amount and liquid addition time, liquid addition interval and liquid addition number to achieve precise automatic operation; the liquid storage tank stores the reaction solution or distilled water, the solenoid valve is connected between the peristaltic pump and the sample automatic reaction module, and the peristaltic pump is arranged between the solenoid valve and the liquid storage tank; after the solenoid valve switch is turned on, the peristaltic pump runs to extract the liquid in the liquid storage tank and transport it to the sample automatic reaction module through the solenoid valve; after the organic sample completes a reaction, the solenoid valve is opened, the peristaltic pump runs to extract the waste liquid in the sample automatic reaction module and transport it to the discharge treatment module for neutralization treatment.

[0093] In some embodiments, the emission treatment module is composed of a waste gas and waste liquid detection unit, a suction pump, and a collection and neutralization box. The suction pump extracts the waste gas and waste liquid generated by the reaction from the sample automatic reaction module and transports them to the collection and neutralization box for neutralization treatment. The waste gas and waste liquid detection unit then detects the treated product and determines that it meets the emission standards before discharging it into the environment. In this embodiment, a peristaltic pump is used as a suction pump to extract the waste gas and waste liquid obtained after the reaction of the organic sample and the acid solution from the sample automatic reaction module and transport them to the neutralization box. The neutralization box is made of PP board. In the neutralization box, the ratio of 1:1.2 is used. Acid and alkali solvents are configured in proportion to convert the waste liquid after the reaction from acid liquid into weak alkaline waste liquid, and then the waste gas and waste liquid detection unit performs pH detection on the converted weak alkaline waste liquid. After meeting the emission standards, the weak alkaline waste liquid in the neutralization box is discharged; in the early stage of the reaction between the organic sample and the acid liquid in the sample automatic reaction module, the carbonate impurities in the organic sample react with the acid liquid to release carbon dioxide, which will directly pass through the exhaust pipe, through the first-level exhaust system, and together with part of the acid gas generated in the working area, be transported to the separation pool to isolate the harmful gas in the water and directly eliminate the harmless gas.

[0097] In some embodiments, the entire automatic enrichment system for deposited insoluble organic matter is controlled by a computer system, which is composed of an online monitoring system and a safety alarm system. The online monitoring system can collect real-time status data of each module and component in the low-temperature enrichment subsystem, such as the speed and pressure of the peristaltic pump in the liquid addition and discharge module, the opening of the solenoid valve, etc. The computer system performs real-time analysis of the collected data according to a built-in program to determine the real-time status of the low-temperature enrichment subsystem, and controls the operation of each module and component in the low-temperature enrichment subsystem based on the real-time analysis results of the collected data, such as controlling the peristaltic pump to transport acid to the reactor at a certain speed.

The peristaltic pump is then controlled to extract the single-phase waste liquid into the waste liquid and waste gas treatment and emission system for neutralization. The computer-controlled automatic control and acquisition system detects that the treated waste liquid and waste gas in the waste liquid and waste gas treatment and emission system meet emission standards before discharging the waste liquid and waste gas. The computer-controlled automatic control and acquisition system detects whether the current number of treatments for carbonate minerals and silicate minerals meets a preset number.
