Description
Technical Field
The invention relates to an installation and construction method for exploiting a methane generating device for a seabed surface exposed combustible ice mineral deposit.
Background
With the huge consumption of resources, people face the huge crisis of resources in particular in the beginning of the 21 st century, the crude oil import in China is more than one hundred million tons as the energy consumption of the large country, the yield of the domestic onshore oil and gas field is reluctantly stable, and experts estimate that the large country hardly has major breakthrough in a short term. Natural gas hydrates, which are readily combustible ice, are gaining favor as an alternative energy source in countries throughout the world, particularly in developed countries.
Taking gas hydrates formed at the sea floor as an example: when the water depth is 300 meters at the ambient temperature of 1-20 ℃, the natural gas hydrate, namely the combustible ice deposit, can be formed as long as the water depth reaches 30 atmospheric pressures; and the environment being above the temperature or/and the environment being below the pressure, the natural gas hydrate is encouraged to decompose into methane and water.
The storage amount of combustible ice mineral deposits in the world is 2 times of the storage amount of combustible minerals such as petroleum, and the combustible ice mineral deposits can be used by global population for 1000 years; theoretical calculation, 1m3Can release 164m of saturated natural gas hydrate under standard conditions3Methane gas, while natural gas hydrate combustion produces only CO2And H2O, which belongs to an inexhaustible green clean energy.
The south China sea contains abundant combustible ice deposits on the sea bottom, however, the combustible ice deposits are not mined out like other sea areas in the world, and the main reason is that the mining cost of the combustible ice is high, about $ 200/m3。
Many "laboratory" methods have been developed, but these methods are in the exploration phase and are difficult to enter into practical, scalable commercial exploitation phases
From a specific technical aspect: the method for exploiting underwater combustible ice has not been available, but a high-depth submersible pump which is necessary when natural gas hydrate needs to be decomposed in an exploitation method is not available, namely, a submersible pump with high diving depth (such as hundreds of meters or even kilometers) is difficult to be available due to the restriction (unsolved) of various technical problems.
The existing submersible pump can only be used under water which is a few meters away from the water surface to achieve the best effect because the key problem of good waterproof sealing of the existing submersible pump is not solved, and the submersible pump also needs to be periodically hoisted and pulled to the shore to remove water seepage maintenance (not maintenance after damage) in the pump, wherein the interval time of the 'periodic shore maintenance' is more than months and less than weeks or even days, and the larger the submersible depth of the submersible pump is, the shorter the period of the 'periodic shore maintenance' is; because of the need for "regular offshore maintenance", it is not luxurious to use very powerful (e.g., megawatts) submersible pumps for underwater work because the single-machine weight of very powerful submersible pumps cannot be very light and it is difficult to "hang ashore" regularly for maintenance to remove seepage water.
Disclosure of Invention
The object or key points of the invention are:
mainly starts from solving the problem of the most spicy deep submersible pump, provides a pressure reduction special mining scheme which can successfully enter a practical stage and finally obtains the cheap methane needed by people for decomposing combustible ice, namely natural gas hydrate into methane and water
The invention has the characteristics that:
since the present invention can solve or achieve many of the problems described above in the "object of the present invention" or "key point of the present invention", it is possible to provide conditions for allowing marine combustible ice, i.e., marine natural gas hydrate, to enter a scale-up mining stage, and also to achieve a degree of commercial mining (profitability).

Detailed Description
In order to achieve the above object of the present invention, the following technical solutions are proposed:
the main structure of the invention is characterized in that:
the methane generating device is characterized by at least comprising a body of a methane generating device, wherein a rigid pipeline 4 is inserted from the sea level and positioned on a seabed rock stratum, the outer bottom surface of the body is provided with an inverted cone-shaped counterweight foundation 8 which can be matched with the position of a joint part of the seabed rock stratum, the lower part in the body is provided with a deep submersible pump B, a broken miscellaneous stone block collecting net W which can vertically rise to the sea level is arranged between the upper part of the deep submersible pump B and a feed inlet 7, a microwave heater R is arranged above the feed inlet 7, and a turnover sealed cabin G mechanism of a bottom machine room is arranged above the microwave heater R;
the feed inlet 7 is provided with a sealing cover 5 which can be opened or closed by remote control turning:
when the sealing cover 5 is opened, the feed inlet 7 can be jointed with the end part of the externally connected underwater conveyer belt D in a non-connection mode, and combustible ice fragments 6 conveyed by the underwater conveyer belt D are accurately received;
an internal remote control water supply pressure-increasing valve 9 is arranged below the water surface at the outer side of the rigid pipeline 4, and the sealing cover 5 can be opened only when the pressure of the internal water supply is increased and is consistent with the pressure of the water body at the outer side;
a drainage pipeline 2 is arranged above the deep submersible pump B and used for externally draining the accumulated water which can be automatically drained at any time through the deep submersible pump B;
when the water body in the rigid pipeline 4 is pumped out by the deep submersible pump B, the water body is indirectly influenced by one atmospheric pressure in the atmospheric space on the water surface, and the indirect influence mode is as follows:
the methane collector 3 generated in the rigid pipeline 4 is finally output from the exhaust pipeline 1 for use by people.
The installation construction method of the invention comprises the following steps:
firstly, arranging an inverted cone-shaped hole which can be matched on an inverted cone-shaped foundation 8 of a methane generation generating device on a submarine rock stratum by a drilling machine;
then, the methane generation generating device is hoisted from the water surface to the position of the inverted cone-shaped hole matched with the methane generation generating device on the water bottom, and the process comprises the following steps: connecting a rigid pipeline 4 from the top of the methane generation generating device to the water surface;
finally, the arrangement of the methane collector 3 above the water surface, the exhaust pipeline 1 and the drainage pipeline 2 is completed;
the vertical drainage pipe part of the drainage pipeline 2 at the vertical section part of the seabed when passing through the position of the turnover sealing hatch cover mechanism G penetrates out of the rigid pipeline 4 and is connected with the outside of the rigid pipeline in an engineering structure mode of the bypassing local design of the drainage pipeline 2;
the methane collector 3 takes into account the working conditions of workers carrying oxygen bottles;
the joint of the rigid pipeline 4 allows the external water body to leak inwards, but the lowest level of the bottom in the methane generating device can be well controlled as long as the deep submersible pump B is used for periodically producing in batches, namely separating combustible ice into methane and water in batches.
The following is explained:
the invention is set on the premise that the mining method similar to the open pit coal mine is adopted, and the combustible ice deposits on the surface of the seabed are mined only under the condition of deep dew, namely all underwater appliances related to the scheme have to be basic conditions capable of bearing deep diving.
Here, it can be said that: all core technologies related to deep diving equipment have been at a level approaching full resolution. The core technology that has been solved here must be done at least to overcome the key drawbacks of the submersible pumps of the prior art: diving is shallow (on the order of tens of meters at most), and the submersible pump is required to be periodically ashore for maintenance (with intervals of months or weeks) for removing internal seepage water, and the length and length of the periodic interval time period are proportional to the diving depth of the submersible pump in diving operation.
Obviously, the key points of the improvement of the invention are as follows:
by arranging the isolating facility of the 'turning sealing hatch cover mechanism G', the device is artificially divided into two parts from the bottom of the device, and mainly the device is divided from the part of a 'machine room' where more facilities or equipment such as a deep submersible pump B and the like are arranged at the bottom of the device, so that the device can be simplified in operation and use for periodically carrying out batch separation of combustible ice fragments into methane and water: for example: the process of frequently increasing pressure and reducing pressure is implemented in the whole separation device, and the process can be limited to be carried out in a part below the sealed cabin cover turning mechanism G, namely the sealed cabin body at the bottom as far as possible, so that the process is beneficial to saving the energy consumption of the whole separation device.
