Description

Technical Field

[0001] The present invention relates to the technical field of shale analysis, and in particular to a device for separating and quantitatively collecting associated liquid fluids in a shale gas analysis process. Background Art

[0002] my country has long been experiencing a shortage of oil and gas resources, and its dependence on foreign oil and gas resources has continued to increase in recent years. Unconventional oil and gas resources will be an important alternative resource for my country to boost its energy supply in the future. Shale oil and gas are self-generating and self-storing unconventional oil and gas resources with widespread distribution and abundant resources. Shale gas, in particular, has become the primary driver of natural gas reserve and production growth in my country in recent years. Due to the abundant nanopores in organic-rich shales, primary pore water and light liquid hydrocarbons are commonly present in shale reservoirs under geological conditions. These liquid fluids associated with shale gas not only occupy a certain amount of nanopore space, influencing the occurrence, enrichment, and development of shale gas, but also contain a wealth of geological and geochemical information, which is crucial for revealing the formation mechanisms of shale gas reservoirs.

[0003] At present, the evaluation of the gas content of shale reservoirs and the prediction of their resources are mainly based on the analysis experiment of fresh shale core samples at the drilling site. By measuring the change curve of the shale analysis gas content over time and combining it with the gas diffusion model, the gas content data of the shale is calculated. However, in the process of heating and analyzing the shale core samples in the existing shale analysis equipment, the original pore water and light hydrocarbon components in the shale core will migrate out along with the shale analysis gas. After migrating out of the analysis tank, they will condense into the migration pipeline due to the decrease in temperature. The condensation of liquid fluids can easily clog the pipeline, affecting the determination of shale analysis gas. At the same time, this part of the condensed original pore water and light hydrocarbon components is difficult to collect and measure. How to effectively achieve the separation and quantitative collection of gas and liquid fluids during the on-site analysis of shale gas is one of the key technical issues currently facing the evaluation of the gas content of shale reservoirs.

[0031] A device for separating and quantitatively collecting associated liquid fluids during shale gas analysis, comprising a device body 1, a sample bin assembly 2 arranged in a 2×3 array is embedded on the top of the device body 1, a comprehensive box 3 arranged in a 2×3 array is embedded on the top of the device body 1, an oil-water separation mechanism 4 is fixedly installed on the bottom of each of the six groups of comprehensive boxes 3, the outer surfaces of the six groups of sample bin assemblies 2 are fixedly connected to the guide pipe assemblies 5, and the tail ends of the six groups of guide pipe assemblies 5 are respectively fixedly connected to the tops of the six groups of comprehensive boxes 3, the six groups of guide pipe assemblies 5 are all arranged in an inclined manner, the outer surfaces of the guide pipe assemblies 5 are fixedly connected to the control valve 6, and the top of the device body 1 is fixedly installed with a An electric heater 7 and a circulation pump 8, and the input end of the circulation pump 8 is fixedly connected to a position lower than the outer surface of the electric heater 7, the circulation pump 8 is located behind a group of sample chamber assemblies 2 in the front, a guide pipe 9 is fixedly connected to a position higher on the surface of the electric heater 7, the output end of the circulation pump 8 is fixedly connected to an integrated pipe 10, the outer surfaces of the six groups of guide pipe assemblies 5 are fixedly sleeved with a thermal insulation layer 11, and the top of the integrated pipe 10 extends into the interior of a group of thermal insulation layers 11 on one side of the circulation pump 8, and the tail end of the guide pipe 9 extends into the interior of a group of thermal insulation layers 11 on the other side of the circulation pump 8, and a derivation pipe 12 is fixedly connected between two adjacent groups of thermal insulation layers 11.

[0032] A heating structure is attached to the interior of the space of the device body 1, and the heating structure is wrapped around the outer surface of the six groups of sample chamber components 2. By operating the heating structure in the device body 1, the six groups of sample chamber components 2 are subjected to thermal energy and heated and analyzed, so that the pore water and light hydrocarbon components associated with the shale core will move along the guide pipe component 5 to the space of the integrated box 3 along with the shale analysis gas, and because the guide pipe component 5 is tilted from top to bottom from the sample chamber component 2 to the integrated box 3, the gas\liquid inside the sample chamber component 2 can be output downward at an angle, thereby effectively preventing the guide pipe component 5 from being blocked. In addition, by operating the electric heater 7 and the circulating pump 8, the electric heater 7 is prompted to heat the water inside its space, and the hot water inside the electric heater 7 space is extracted by the circulating pump 8, and the hot water inside the electric heater 7 space is transferred through the integrated box 3. The pipe 10 is introduced into the space of a group of thermal insulation layers 11 at the front side near the circulation pump 8, and then flows in the space of six groups of thermal insulation layers 11 and six groups of outlet pipes 12 in the order of thermal insulation layers 11 and outlet pipes 12, thereby effectively increasing the temperature of the outer wall of the guide pipe assembly 5, avoiding condensation of shale analysis gas flowing in the space of the guide pipe assembly 5, and further reducing the probability of blockage of the guide pipe assembly 5, and finally returning to the space of the electric heater 7 through the guide pipe 9. With the continuous operation of the circulation pump 8 and the electric heater 7, the purpose of hot water circulation can be achieved, thereby effectively ensuring that the water body inside the thermal insulation layer 11 is always within the set high temperature range during the operation period of the device; the six groups of sample chamber assemblies 2 in the device are integrated into one device, and analysis operations can be performed on six groups of samples at the same time.

[0033] A horizontal panel 13 is fixedly installed on the inner wall of the device body 1, and the top of the horizontal panel 13 is in contact with the bottom of the oil-water separation mechanism 4. The tops of the six groups of integrated boxes 3 are all fixedly connected with exhaust pipes 14. The bottoms of the exhaust pipes 14 are fixedly connected with the first vertical pipe 15 and the second vertical pipe 16. The outer surface of the exhaust pipe 14 is fixedly connected with three groups of valves 17 arranged front and back, and the three groups of valves 17 are arranged at intervals between the first vertical pipe 15 and the second vertical pipe 16. The outer surface of the first vertical pipe 15 is fixedly connected with a regulating valve 18. The top of the horizontal panel 13 is fixedly connected with a vacuum pump 19, and the input end of the vacuum pump 19 is fixedly connected to the tail end of the first vertical pipe 15. The tail end of the second vertical pipe 16 is threadedly connected with a gas collection bottle 20. The outer surface of the exhaust pipe 14 is fixedly connected with a gas volume sensor 21, and the gas volume sensor 21 is located behind the three groups of valves 17.

[0034] Before the gas flows to the exhaust pipe 14, the vacuum pump 19 is operated to cause it to perform vacuum operations on the first vertical pipe 15 and the exhaust pipe 14 to ensure that there is no impurity gas interfering with the accuracy of the experimental data during subsequent gas collection; the gas transported to the interior of the space of the integrated box 3 along the guide pipe assembly 5 can be discharged upward along the exhaust pipe 14, and the flow of the gas passing through the exhaust pipe 14 can be monitored by the gas volume sensor 21. When the two groups of valves 17 in the front are in the open state and the group of valves 17 and the regulating valve 18 in the rear are in the closed state, the gas inside the space of the exhaust pipe 14 can enter the space inside the gas collection bottle 20 along the second vertical pipe 16.

[0035] The structure of the guide pipe assembly 5 includes a guide pipe 22, an annular ring 23, a threaded seat 24 and a plug-in pipe 25. The annular ring 23 is fixedly sleeved on the outer surface of the guide pipe 22, the threaded seat 24 is fixedly installed on the top of the integrated box 3, the plug-in pipe 25 is fixedly connected to the top of the threaded seat 24, and the plug-in pipe 25 is slidably inserted into the interior of the guide pipe 22. The structure of the guide pipe assembly 5 also includes a T-shaped sleeve 26 and a connecting pipe 27. The T-shaped sleeve 26 is rotatably sleeved on the outer surface of the annular ring 23, the connecting pipe 27 is fixedly installed on the bottom of the T-shaped sleeve 26, and the connecting pipe 27 is threadedly sleeved on the outer surface of the threaded seat 24.

[0036] The guide tube assembly 5 in this device is itself in a decomposable state, and can then be separated from the integrated box 3, so as to facilitate the cleaning of the inner wall of the guide tube 22. In the process of driving the sample chamber assembly 2 to separate upward from the device body 1, by applying a rotational force in a set direction to the T-shaped sleeve 26, the connecting tube 27 is driven to gradually rotate upward and separate along the outer surface of the threaded seat 24. At this time, since the threaded seat 24 and the integrated box 3 are in an inseparable state, the guide tube 22 follows and separates from the plug-in tube 25, thereby completing the unilateral disassembly operation of the guide tube 22.

[0037] The structure of the oil-water separation mechanism 4 includes a liquid dosing device 28, a delivery pipe 29, a water collection bottle 30, a horizontal plate 31 and an oil collection bottle 32. The liquid dosing device 28 is fixedly installed at the bottom of the integrated box 3, the water collection bottle 30 is installed on the top of the horizontal panel 13, the delivery pipe 29 is connected between the liquid dosing device 28 and the water collection bottle 30, the outer surface of the delivery pipe 29 is fixedly connected with an electronic valve, the horizontal plate 31 is fixedly installed on the outer surface of the liquid dosing device 28, the oil collection bottle 32 is installed on the top of the horizontal plate 31, and the structure of the oil-water separation mechanism 4 also includes a separation pipe 33, an oil inlet hydrophobic layer 34, a locking cover 35, a square block 36, an electric push rod 37, a stretch hose 38 and The suction pump 39 and the separation tube 33 are slidably inserted into the top of the liquid metering device 28, the locking cover 35 is threadedly sleeved on the bottom of the separation tube 33, the oil inlet hydrophobic layer 34 is arranged between the separation tube 33 and the locking cover 35, the square block 36 is fixedly installed on the outer surface of the separation tube 33, the electric push rod 37 is fixedly connected to the top of the liquid metering device 28, and the telescopic end of the electric push rod 37 is fixedly connected to the top of the square block 36, the stretch hose 38 is fixedly inserted into the inside of the separation tube 33, the suction pump 39 is installed on the top of the oil collection bottle 32, and the input end of the suction pump 39 is fixedly connected to the tail end of the stretch hose 38, and the output end of the suction pump 39 is inserted into the inside of the oil collection bottle 32.

[0038] Among the gaseous and liquid substances in the space of the integrated box 3, the liquid substance will flow downward to the space of the liquid dosing device 28 under its own gravity, and then by running the electric push rod 37, it will be prompted to maintain a uniform speed to extend downward, thereby generating a downward driving force on the square block 36, and then drive the separation tube 33, the oil inlet hydrophobic layer 34 and the locking cover 35 to move at a uniform speed from top to bottom along the interior of the liquid dosing device 28. With the help of the kinetic energy of the downward movement of the separation tube 33, the oil inlet hydrophobic layer 34 and the locking cover 35 and the pressure difference between the upper and lower parts of the oil inlet hydrophobic layer 34, the oil inside the space of the liquid dosing device 28 will enter the space inside the separation tube 33 along the oil inlet hydrophobic layer 34, thereby achieving the purpose of separating oil and water. Among the pressures on the lower surface of layer 34, the pressure fed back by the oil is less than the pressure fed back by the water-oil mixture, which is less than the pressure fed back by the water body. The inside of the separation tube 33 is set as the inside, while the inside of the liquid doser 28 and the outer surface of the separation tube 33 are set as the outside. The internal pressure of the separation tube 33 is a combination of atmospheric pressure and the internal oil pressure. The outside pressure is the pressure fed back by the oil-water mixture on the lower surface of the oil-inlet hydrophobic layer 34 at a set depth position inside the space of the liquid doser 28. The outside pressure of the separation tube 33 is greater than the inside pressure, so the oil will not fall down after entering it. In addition, after the oil and water are separated, the suction pump 39 is operated to cause the oil inside the space of the separation tube 33 to flow along the stretching hose 38 into the space inside the oil body collection bottle 32.

[0039] The structure of the sample bin assembly 2 includes a sample bin cylinder 40, a quartz sand layer 41, a core sample 42, a sealing cover 43 and a temperature control and timing integrated device 44. The core sample 42 is arranged inside the sample bin cylinder 40. There are two groups of quartz sand layers 41, and the two groups of quartz sand layers 41 are respectively arranged above and below the core sample 42. The sealing cover 43 is fixedly installed on the top of the sample bin cylinder 40 by screws. The temperature control and timing integrated device 44 is fixedly installed on the top of the sealing cover 43. A plurality of groups of evenly arranged control buttons 45 are installed on the top of the device body 1. A computer control display 46 is embedded in the top of the device body 1, and the computer control display 46 is located in front of the control button 45.

[0040] During the process of heating and analyzing the six groups of sample chamber assemblies 2 through the device main body 1, the heat energy received by the sample chamber cylinder 40 can be transferred to the core sample 42 through the quartz sand layer 41 inside its space, so that the pore water and light hydrocarbon components associated with the shale core will move along the guide tube assembly 5 to the space of the integrated box 3 along with the shale analysis gas. The sealing cover 43 and the sample chamber cylinder 40 are in a detachable combination state, which makes it convenient to clean the space inside the sample chamber cylinder 40. The temperature control and timing integrated device 44 is used to monitor the actual temperature inside the space of the sample chamber assembly 2 and feed it back to the computer control display 46 electrically connected to it. At the same time, it can time the time for the device main body 1 to heat and analyze the sample chamber assembly 2. The control button 45 is used to operate various functions of the device main body 1.

[0041] Working principle: When the six groups of sample bin assemblies 2 are subjected to heat energy and heated and analyzed, the pore water and light hydrocarbon components associated with the shale core can be transported along the shale analysis gas along the guide pipe assembly 5 to the space of the integrated box 3, and because the guide pipe assembly 5 is tilted from top to bottom from the sample bin assembly 2 to the integrated box 3, the gas\liquid inside the sample bin assembly 2 can be output downward at an angle, which can effectively prevent the guide pipe assembly 5 from being blocked. In addition, by running the electric heater 7 and the circulation pump 8, the electric heater 7 is prompted to heat the water inside its space, and the water circulates along the electric heater 7, the circulation pump 8, the integrated pipe 10, the six groups of thermal insulation layers 11, the six groups of outlet pipes 12 and the guide pipe 9, thereby effectively increasing the temperature of the outer wall of the guide pipe assembly 5, and the liquid substance entering the space inside the integrated box 3. It will flow downward to the space inside the liquid meter 28 under its own gravity, and then extend downward at a uniform speed through the electric push rod 37, driving the square block 36, the separation tube 33, the oil inlet hydrophobic layer 34 and the locking cover 35 to move at a uniform speed from top to bottom along the interior of the liquid meter 28. With the help of the kinetic energy of the downward movement of the separation tube 33, the oil inlet hydrophobic layer 34 and the locking cover 35 and the pressure difference between the upper and lower parts of the oil inlet hydrophobic layer 34, the oil inside the space of the liquid meter 28 flows along the oil inlet hydrophobic layer 34 into the space inside the separation tube 33, and the gas inside the integrated box 3 flows into the exhaust pipe 14. When the two groups of valves 17 in front are in the open state and the group of valves 17 and the regulating valve 18 in the rear are in the closed state, the gas inside the space of the exhaust pipe 14 can enter the space inside the gas collection bottle 20 along the second vertical tube 16.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
