Problems solved by technology

At present, domestic research on in-situ flow rate online measurement devices for submarine cold seep natural gas seepage has been carried out. Our country is blank in this field, but the two sets of devices successfully developed are difficult to be used for deep-sea observation due to limitations of materials and components, and the error of flow measurement results is relatively large

The valve 200 in this embodiment is a pressure-resistant underwater solenoid valve, and the first liquid level electrode 300 and the second liquid level electrode 400 are liquid level electrodes in a deep ...

Embodiment 2

[0046] Such as Figure 4 Shown is an embodiment of the subsea hydrocarbon natural gas flow measurement system of the present invention, including a detection control chip 500 and a subsea hydrocarbon natural gas flow measurement device as described in Embodiment 1, the first liquid level electrode 300, the second liquid level electrode The bit electrode 400 is connected to the input end of the detection control chip 500 , the valve 200 is connected to the output end of the detection control chip 500 , and the detection control chip 500 is connected to the storage module 600 .

[0047] During the implementation of this embodiment, the detection control chip 500 receives the liquid level signal detected by the first liquid level electrode 300 and the second liquid level electrode 400, and sends a control signal to the valve 200 according to the received liquid level signal, and operates the valve 200 The number of times and action time are stored in the storage module 600, and t...

Embodiment 3

[0049] This embodiment is an embodiment of the seabed hydrocarbon natural gas flow measurement method of the present invention, comprising the following steps:

[0050] S10. The natural gas leaking upwards enters the gas collection chamber 100 through the bubble collection device, and the seawater in the gas collection chamber 100 is discharged downward;

[0051] S20. When the liquid level of seawater in step S10 drops to the position of the second liquid level electrode 400, the control opens the valve 200, the gas in the gas collection chamber 100 is emptied, and the seawater liquid level in the gas collection chamber 100 rises to the second level at the same time. a position of the liquid level electrode 300;

Abstract

The present invention relates to the technical field of seabed measurement, and more specifically, to a seabed hydrocarbon natural gas flow measurement apparatus, system, and method. The apparatus comprises a gas collecting chamber connected to a bubble collection apparatus, a valve disposed in communication with the gas collecting chamber, and a first liquid level electrode, a second liquid levelelectrode, and a valve that are used to indicate a liquid level variation. The first liquid level electrode is disposed on the top of the gas collecting chamber, and the second liquid level electrodeis disposed on the bottom of the gas collecting chamber. According to the seabed hydrocarbon natural gas flow measurement apparatus, natural gas leaking upwards enters into the gas collecting chamberwith a quantitative volume by using the bubble collection apparatus, sea water in the gas collecting chamber is removed downwards, when the liquid level reaches a position of the second liquid levelelectrode, the valve is controlled to open, gas in the gas collecting chamber is evacuated, and a sea water level in the gas collecting chamber rises at the same time. A seabed hydrocarbon natural gasflow is measured by repeating this process. The apparatus can not only be used for online measurement of a shallow sea seabed gas seepage in-situ flow, but also be used for online measurement of a deep sea seabed gas seepage in-situ flow.

Description

technical field [0001] The present invention relates to the technical field of seabed measurement, and more specifically, to a device, system and method for measuring flow of seabed hydrocarbon natural gas. Background technique [0002] The amount of methane released into the ocean water body and the atmosphere through the seepage of submarine cold seep natural gas every year is very alarming. The preliminary estimate is greater than 10Tg (1012g) per year, and methane is a strong greenhouse gas, and its greenhouse effect is the same as that of carbon dioxide. Such a huge amount of methane is an important factor affecting global climate change. Therefore, on-line in-situ detection of the seepage rate of submarine cold seep natural gas has important economic value and scientific significance. At present, domestic research on in-situ flow rate online measurement devices for submarine cold seep natural gas seepage has been carried out. Our country is blank in this field, but t...
