Put, high pressure pump group, air collector, the first producing well component and the second producing well component extend to the stacked storage of three gas from sea level
Layer, the first producing well component are connected by conveyance conduit with gas and water separator and air collector, and the second producing well component passes through defeated
Pipeline is sent to be connected with gas and water separator and high pressure pump group, gas and water separator passes through conveyance conduit and high pressure pump group and air collector
Connect, safety valve is provided with conveyance conduit.
Wherein, the first producing well component and the second producing well component include oil pipe, sleeve pipe, perforation and packer, oil
Pipe covering is cased with sleeve pipe, and multigroup perforation is offered on sleeve pipe, and packer is installed between oil pipe and sleeve pipe, position is located at natural gas
Hide and water-soluble gas reservoir line of demarcation.
Preferably, temperature/pressure sensor is also included, described temperature/pressure sensor is distributed in sleeve outer wall.
The invention has the advantages that：
1. the present invention is by using two-tube co-development pattern, with the economic benefit of free natural gas make up water-soluble gas reservoir compared with
Low exploitation benefit, gas hydrates are carried out with heating exploitation with the high-temperature stratum water of output, unnecessary output water is noted again
Enter water-soluble gas reservoir to keep its strata pressure.This method is economically feasible, and can make full use of natural gas resource.
2. in reasonable actual mining system, it is additionally arranged temperature/pressure sensor and is scattered in producing well outer wall, can be in real time to multiple
The extra large layer situation of miscellaneous change is monitored in real time.
