Description

Technical Field

[0001] This utility model relates to the technical field of rock physics, and more specifically, to a device for measuring the acoustic and electrical properties of water bodies under pressure dissolved gas. Background Technology

[0002] After natural gas is formed from source rocks, it first enters the pore water medium and undergoes dissolution. Only after dissolution can the excess natural gas migrate and accumulate in the gaseous state. Therefore, the amount of natural gas dissolved in formation water is also significant. A correct understanding of the solubility of natural gas in formation water is of great importance for mastering the enrichment and accumulation patterns of natural gas and for the exploitation of natural gas.

[0003] Natural gas is primarily composed of methane gas. During the dissolution of methane in water, the acoustic and electrical properties of the water change. Therefore, by obtaining the acoustic and electrical properties of the water, the solubility of methane in the water can be determined, and measuring these properties is more convenient than directly measuring the solubility of methane. However, currently, there is no device that can accurately measure the relationship between the amount of methane dissolved and the acoustic and electrical properties of the water during the process of methane dissolving to saturation under specific conditions. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technology in that there is no device that can accurately measure the relationship between the amount of gas dissolved during the process of methane gas dissolving to saturation under specific conditions and the acoustic and electrical properties of water. This invention provides a device for measuring the acoustic and electrical properties of water under pressure dissolved gas. The device in this solution can accurately measure the relationship between the amount of gas dissolved during the process of methane gas dissolving to saturation under specific conditions and the acoustic and electrical properties of water.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A device for measuring the acoustic and electrical properties of dissolved gas in water is provided, comprising a reaction vessel, a piston container, a constant-speed and constant-pressure pump, and a heating module. The reaction vessel includes a cylindrical body and an acoustic and electrical probe installed on the cylindrical body, the probe being used to measure the acoustic and electrical properties of the liquid within the cylindrical body. The piston container includes a shell and a piston slidably connected to the inner cavity of the shell, the piston dividing the inner cavity of the shell into a gas chamber and a pushing chamber, the gas chamber being communicatively connected to the inner cavity of the cylindrical body. The constant-speed and constant-pressure pump is used to pump liquid into the pushing chamber or the inner cavity of the cylindrical body at a constant flow rate and pressure, the output end of the constant-speed and constant-pressure pump being communicatively connected to the inner cavity of the cylindrical body or the pushing chamber. The heating module is used to heat the shell and the cylindrical body. The constant-speed and constant-pressure pump can pump liquid out at a constant pressure and a constant speed, the constant pressure and speed values ​​of which can be manually adjusted and set. The inner wall of the shell is tightly fitted to the side wall of the piston, preventing communication between the gas chamber and the pushing chamber. When the gas chamber is connected to the cylinder, the gas in the gas chamber can enter the inner cavity of the cylinder, but the liquid in the inner cavity of the cylinder cannot enter the gas chamber.

[0007] Before use, the pressure dissolved gas water acoustic and electrical property measuring device of this invention evacuates the inner cavity of the cylinder and the inner cavity of the shell. During use, the output end of the constant-speed, constant-pressure pump is first connected to the inner cavity of the cylinder. Water is pumped into the inner cavity of the cylinder by the constant-speed, constant-pressure pump until the acoustic and electrical probe detects that the acoustic and electrical properties of the water in the inner cavity of the cylinder no longer change. At this point, the pump cavity is full of water, and the pressure of the water in the pump cavity is the same as the pressure of the water pumped out by the constant-speed, constant-pressure pump. Simultaneously, the heating module heats the piston container until it reaches the target temperature. Once the piston container has reached the target temperature, methane gas is introduced into the gas chamber of the piston container, filling it completely.

[0008] Once the acoustic and electrical properties of the water inside the cylinder no longer change, disconnect the output of the constant-speed, constant-pressure pump from the cylinder's inner cavity. Then, connect the output of the constant-speed, constant-pressure pump to the push chamber, and pump water into the push chamber. After water is injected into the push chamber, the water flow pushes the piston into the gas chamber, compressing the methane gas inside. When the piston stops moving, it indicates that the pressure in the push chamber and the gas chamber is the same, meaning the gas in the gas chamber has reached the target pressure. Record the flow rate of the constant-speed, constant-pressure pump at this point. After disconnecting the output of the constant-speed, constant-pressure pump from the cylinder's inner cavity, simultaneously heat the cylinder using the heating module until the cylinder reaches the target temperature.

[0009] After the cylinder has reached the target temperature and the gas chamber of the piston container has reached the target pressure, the inner cavity of the cylinder is connected to the gas chamber. After a period of time, the connection between the inner cavity of the cylinder and the gas chamber is then disconnected. When the inner cavity of the cylinder is connected to the gas chamber, the methane gas in the gas chamber enters the inner cavity of the cylinder and dissolves in the water inside the inner cavity. After the methane gas dissolves in the water, the volume of the gas chamber in the inner cavity of the shell decreases, and the piston moves from the inner cavity of the shell towards the gas chamber. At this time, the constant speed and pressure pump continues to pump water into the pushing chamber. The flow rate of the constant speed and pressure pump is recorded when it pumps water into the pushing chamber. The increase in the flow rate of the constant speed and pressure pump is the volume of methane gas dissolved in the water.

[0010] When methane gas dissolves in water, the acoustic and electrical properties of the water change. These changes can be monitored using an acoustic and electrical probe. The acoustic and electrical properties of water include acoustic and electrical properties, namely, the sound waves and electrical resistance within the water. After disconnecting the inner cavity of the cylinder from the gas cavity, the acoustic and electrical properties of the water in the inner cavity are recorded when the probe detects no further change. The inner cavity is then reconnected to the gas cavity, and the process is repeated until the acoustic and electrical properties of the water no longer change after this connection, indicating that the water is saturated with methane. The acoustic and electrical properties of the water at this point are also recorded. Based on the obtained data on the amount of gas dissolved and the changes in the acoustic and electrical properties of the water, a curve showing the changes in the acoustic and electrical properties of the water during the methane dissolution process can be generated. This curve can be consulted to determine the methane solubility in the target water body during subsequent use.

[0011] The pressure-dissolved gas water acoustic and electrical property measuring device of this invention can measure the changes in the acoustic and electrical properties of water during the process of methane gas dissolving in water under specified temperature and pressure conditions. It can obtain the relationship between the amount of gas dissolved during the process of methane gas dissolving to saturation and the acoustic and electrical properties of water, so as to quickly obtain the methane solubility in the target water body after obtaining the acoustic and electrical property data of the target water body.

[0012] Furthermore, the cylinder is also equipped with an insulating sleeve and insulating end plates. The insulating sleeve is fixedly installed inside the cylinder, and its outer wall is tightly fitted against the inner wall of the cylinder. There are two insulating end plates, which are respectively fixedly installed at both ends of the cylinder. The insulating sleeve and insulating end plates provide an insulating environment for the inner cavity of the cylinder, preventing external interference when the acoustic-electric probe measures the acoustic-electric properties of the water inside the cylinder. The insulating end plates are generally ceramic plates, and the insulating sleeve is also generally a ceramic sleeve, as ceramic material has high hardness and good insulation effect.

[0013] Furthermore, the acoustic-electric probe is fixedly installed in the cylinder, located between the cylinder and the insulating end piece. There are two acoustic-electric probes, located at the top and bottom of the cylinder, respectively. Installing the probes between the cylinder and the insulating end piece prevents external interference from affecting the acoustic-electric data measured by the probes. With two probes, when the acoustic-electric data measured by the two probes are consistent and no longer change, it indicates that the methane gas is uniformly distributed in the water after dissolving. This data represents the acoustic-electric properties of the water when methane gas is dissolved in water.

[0014] Furthermore, the heating module includes a heating wire and a temperature sensor. The heating wire is wound around the outer wall of the cylinder and the outer wall of the shell, and the temperature sensor is connected to the heating wire. The heating wire can be a resistance thermometer wire, and the temperature sensor can control the heating temperature of the heating wire.

[0015] Furthermore, the shell is provided with a first branch pipe and a second branch pipe communicating with the gas chamber. The other end of the first branch pipe is connected to the inner cavity of the cylinder, and the other end of the second branch pipe is used to connect to a gas source. A first switch is provided on the first branch pipe, and a second switch is provided on the second branch pipe. The output end of the constant speed and constant pressure pump is provided with a third branch pipe and a fourth branch pipe. The other end of the third branch pipe is connected to the inner cavity of the cylinder, and the other end of the fourth branch pipe is connected to the push chamber. A third switch is provided on the third branch pipe, and a fourth switch is provided on the fourth branch pipe. When methane gas is injected into the gas chamber, the second switch on the second branch pipe is turned on; when the constant speed and constant pressure pump pumps water into the inner cavity of the cylinder, the third switch on the third branch pipe is turned on; when the constant speed and constant pressure pump pumps water into the push chamber, the fourth switch on the fourth branch pipe is turned on; when it is necessary for the gas chamber to communicate with the inner cavity of the cylinder, the first switch on the first branch pipe is turned on.

[0016] Furthermore, it also includes a housing, with both the reaction vessel and the piston container installed within the housing's inner cavity. The first switch, second switch, third switch, and fourth switch are all mounted on the surface of the housing. The fact that the first, second, and third switches are all mounted on the surface of the housing facilitates operation.

[0017] Furthermore, the inner cavity of the outer shell is also provided with a clamping assembly for holding and fixing the reactor. The clamping assembly includes a lifting part and an abutting part. The reactor is mounted on the lifting part, and the lifting part can drive the reactor upward until it abuts against the abutting part. A pressure sensor is also included, which is mounted on the abutting part and can measure the pressure between the reactor and the abutting part. The clamping assembly facilitates the removal and replacement of the reactor from the outer shell. The lifting part can be a lifting cylinder or a lifting electric cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0027] Example 1

[0028] This embodiment is a first embodiment of a device for measuring the acoustic and electrical properties of water bodies by pressure dissolved gas, such as... Figure 1 and Figure 4 As shown, the system includes a reaction vessel, a piston container, a constant-speed and constant-pressure pump, and a heating module. The reaction vessel includes a cylinder 1 and an acoustic-electric probe 2 installed on the cylinder 1. The acoustic-electric probe 2 is used to measure the acoustic-electric properties of the liquid inside the cylinder 1. The piston container includes a shell 3 and a piston 4 slidably connected to the inner cavity of the shell 3. The piston 4 divides the inner cavity of the shell 3 into a gas chamber 301 and a pushing chamber 302. The gas chamber 301 and the pushing chamber 302 are located on opposite sides of the piston 4 and are not connected. The gas chamber 301 can be connected to the inner cavity of the cylinder 1. The constant-speed and constant-pressure pump is used to pump liquid into the pushing chamber 302 or the inner cavity of the cylinder 1 at a constant flow rate and pressure. The input end of the constant-speed and constant-pressure pump is connected to the liquid source, and the output end can be connected to the inner cavity of the cylinder 1 or the pushing chamber 302. The heating module can heat the shell 3 and the cylinder 1.

[0029] A constant speed and constant pressure pump can pump liquid at a constant pressure and a constant speed. The constant pressure and speed of the output liquid can be manually set by the controller of the constant speed and constant pressure pump.

[0030] The working principle or process of this embodiment is as follows:

[0031] Before use, the pressure dissolved gas water acoustic-electric property measuring device of this embodiment evacuates the inner cavity of the cylinder 1 and the inner cavity of the shell 3. During use, the output end of the constant speed and pressure pump is first connected to the inner cavity of the cylinder 1. Water is pumped into the inner cavity of the cylinder 1 by the constant speed and pressure pump until the acoustic-electric probe 2 detects that the acoustic-electric properties of the water in the inner cavity of the cylinder 1 no longer change. At this point, the pump body is full of water, and the pressure of the water in the pump body is the same as the pressure of the water pumped out by the constant speed and pressure pump. Simultaneously, the heating module heats the piston container until it reaches the target temperature. After the piston container reaches the target temperature, methane gas is introduced into the gas chamber 301 of the piston container, filling the gas chamber 301 of the piston container with methane gas.

[0032] Once the acoustic and electrical properties of the water inside the cylinder 1 no longer change, disconnect the output of the constant-speed, constant-pressure pump from the cylinder 1. Then, connect the output of the constant-speed, constant-pressure pump to the push chamber 302, and pump water into the push chamber 302. After water is injected into the push chamber 302, the water flow pushes the piston 4 into the gas chamber 301, compressing the methane gas inside. When the piston 4 stops moving, it indicates that the pressure in the push chamber 302 and the gas chamber 301 are the same, meaning the gas in the gas chamber 301 has reached the target pressure. Record the flow rate of the constant-speed, constant-pressure pump at this point. After disconnecting the output of the constant-speed, constant-pressure pump from the cylinder 1, simultaneously heat the cylinder 1 using the heating module until the temperature of the cylinder 1 reaches the target temperature.

[0033] After the cylinder 1 has reached the target temperature and the gas chamber 301 of the piston container has reached the target pressure, the inner cavity of the cylinder 1 is connected to the gas chamber 301. After a period of time, the connection between the inner cavity of the cylinder 1 and the gas chamber 301 is disconnected. When the inner cavity of the cylinder 1 is connected to the gas chamber 301, the methane gas in the gas chamber 301 enters the inner cavity of the cylinder 1 and dissolves in the water inside the inner cavity of the cylinder 1. After the methane gas dissolves in the water, the volume of the gas chamber 301 in the inner cavity of the shell 3 decreases, and the piston 4 moves towards the gas chamber 301 in the inner cavity of the shell 3. At this time, the constant speed and pressure pump continues to pump water into the push chamber 302. The flow rate of the constant speed and pressure pump is recorded when it pumps water into the push chamber 302. The increase in the flow rate of the constant speed and pressure pump is the volume of methane gas dissolved in the water.

[0034] After methane gas dissolves in water, the acoustic and electrical properties of the water change. These changes can be monitored using an acoustic and electrical probe 2. After disconnecting the inner cavity of cylinder 1 from the gas chamber 301, the acoustic and electrical properties of the water in the inner cavity of cylinder 1 are recorded when the probe 2 detects no further change. The inner cavity of cylinder 1 is then reconnected to the gas chamber 301, and the aforementioned steps are repeated until the acoustic and electrical properties of the water no longer change after this connection, indicating that the water is saturated with methane. The acoustic and electrical properties of the water at this point are also recorded. Based on the obtained data on the amount of gas dissolved and the changes in the acoustic and electrical properties of the water, an acoustic and electrical property change curve of the water during the methane dissolution process can be obtained. This curve can be consulted to determine the methane solubility in the target water body during subsequent use.

[0035] The beneficial effects of this embodiment are as follows:

[0036] The pressure-dissolved gas water acoustic and electrical property measuring device of this embodiment can measure the changes in the acoustic and electrical properties of water during the process of methane gas dissolving in water under specified temperature and pressure conditions. It can obtain the relationship between the amount of gas dissolved during the process of methane gas dissolving to saturation and the acoustic and electrical properties of water, so as to quickly obtain the methane solubility in the target water body after acquiring the acoustic and electrical property data of the target water body.
