Abstract
The invention relates to the technical field of petroleum and natural gas drilling coring, in particular to a semiconductor refrigeration composite inner barrel for coring of combustible ice. A battery pack and a coordinated control system (CCS) are installed inside a protection joint of the semiconductor refrigeration composite inner barrel and are connected. An outer protection barrel and an inner protection barrel are connected to the lower end of the protection joint. The lower end of the outer protection barrel and the lower end of the inner protection barrel are both connected with the upper end of a lower protection joint. The outer protection barrel is arranged outside the inner protection barrel. A semiconductor flexible refrigeration belt is arranged between the outer protection barrel and the inner protection barrel. The CCS is connected with the semiconductor flexible refrigeration belt through a connection line. The semiconductor refrigeration composite inner barrel achieves the automatic control and refrigeration functions, and can automatically detect the temperature of a rock core of the inner barrel and then start a semiconductor refrigeration device according to the temperature, thereby achieving continuous refrigeration on the rock core of the inner barrel, preventing combustible ice from volatilizing due to time rising in the drilling process, and increasing the acquisition probability of combustible ice substances.
Description
Technical field:
The present invention relates to oil and gas drilling and coring delivery technical field, core particularly to a kind of combustible ice and use quasiconductor
Refrigeration composite inner barrel.
Background technology:
Combustible ice (hydrate of natural gas) can be to a transition directly to gaseous state from solid-state, in combustible ice drilling process, because rising
Brill temperature raises, and causes being difficult to obtaining actual combustible ice sample, the physical study of combustible ice causes having a strong impact on, constrains
The progress of its exploration and development, existing heat preservation technology blocks, mainly by vacuum or insulation material, the biography that outside heat is inside
Broadcast, but the temperature that this technology can not effectively prevent inner core raises.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of combustible ice and cores and use semiconductor refrigerating composite inner barrel, this device
Achieve to have and automatically control and refrigeration, it is possible to automatically detect the temperature of inner core rock core, and partly lead according to the startup of this temperature
System device for cooling, it is achieved the lasting refrigeration to inner core rock core, prevents combustible ice in trip-out process because temperature raises and produces and wave
Outbreak use, promotes the acquisition probability that combustible ice is in kind.Overcome existing coring inner drum heat preservation technology and can not effectively prevent inner core
The deficiency that temperature raises.
The technical solution used in the present invention is: a kind of combustible ice is cored and used semiconductor refrigerating composite inner barrel, including protection
Joint；Joint is internally installed set of cells and CCS system in protection, and set of cells is connected with CCS system, and protection joint lower end connects
Having outer layer protection cylinder and internal layer protection cylinder, outer layer protection cylinder is all connected with lower protection upper end of joint with internal layer protection cylinder lower end,
Outer layer protection cylinder is placed in outside internal layer protection cylinder, is provided with semiconductor flexible refrigeration band between outer layer protection cylinder and internal layer protection cylinder,
CCS system is connected with semiconductor flexible refrigeration band by connecting line.
The invention has the beneficial effects as follows: the present invention has and automatically controls and refrigeration, it is possible to detection inner core rock core automatically
Temperature, and according to this temperature start semiconductor cooling device, it is achieved the lasting refrigeration to inner core rock core, prevent combustible ice rise
Produce volatilization because temperature raises during brill, promote the acquisition probability that combustible ice is in kind.
Accompanying drawing illustrates:
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
As it is shown in figure 1, a kind of combustible ice is cored and is used semiconductor refrigerating composite inner barrel, including protection joint 2；Protection joint 2
Internally installed have set of cells 1 and CCS system 7, and set of cells 1 is connected with CCS system 7, and protection joint 2 lower end connects has outer layer to protect
Casing 3 and internal layer protection cylinder 5, outer layer protection cylinder 3 is all connected with lower protection joint 6 upper end with internal layer protection cylinder 5 lower end, outer layer
Protection cylinder 3 is placed in outside internal layer protection cylinder 5, is provided with semiconductor flexible refrigeration band 4 between outer layer protection cylinder 3 and internal layer protection cylinder 5,
CCS system 7 is connected with semiconductor flexible refrigeration band 4 by connecting line.
Combustible ice oil reservoir is in cryogenic high pressure state, therefore, must keep the temperature of inner core, prevent the when of trip-out
Temperature raises the volatilization causing combustible ice rock core.CCS system 7 is the core institution of the present invention, is responsible for measuring in real time the temperature of inner core
Degree, CCS system 7 possesses delay start function, it is achieved instrument is lower boring when, and system does not starts, and pulling out of hole when, just opens
Beginning measures, and the electricity of CCS system 7 is mainly supplied by set of cells 1；Protection joint 2 major function is protection set of cells 1 He
CCS system 7, and the connection with top is provided；Pulling out of hole when, CCS system 7 measures inner core temperature at any time, when internal layer is protected
When cylinder 5 temperature raises, CCS system 7 just opens semiconductor flexible refrigeration band 4, starts refrigerating function, makes the temperature of internal layer protection cylinder 5
Degree reduces again, arrives initial condition when pulling out of hole, when temperature is reduced to original temperature, system stalls, reenters
Next cycle of operation.The present invention cannot be only used for underground work, it is possible to realizes Ground Operation as required, and the present invention can be on ground
Face carry out set of cells 1 change to realize the lasting constant temperature of inner core rock core, until rock core enters laboratory and carries out next step and analyze.
It is understood that above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and be not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, still can carry out the present invention
Amendment or equivalent, to reach identical technique effect；As long as meet use needs, all protection scope of the present invention it
In.
