Claim 0:
1. A comprehensive three-dimensional exploitation experimental system for large-scale and full-sized exploitation wells, comprising:
a reactor, wherein the reactor is configured to prepare a natural gas hydrate sample, for simulating an environment for forming a natural gas hydrate reservoir in seafloor sediments, wherein the reactor comprises a reactor body, an upper cover disposed at an upper surface of the reactor body, and a lower cover disposed at a lower surface of the reactor body;
a gas introducing module, wherein the gas introducing module is configured to introduce a gas to the reactor during a hydrate formation;
a liquid introducing module, wherein the liquid introducing module is configured to introduce liquid to the reactor during the hydrate formation;
a temperature regulating module, wherein the temperature regulating module is configured to regulate a temperature in the reactor; and
a data-collecting-processing-displaying module, configured to collect, store, process and display data of the comprehensive three-dimensional exploitation experimental system during an experiment, wherein:
an upper circulation coil and a lower circulation coil are respectively disposed at an upper end and a lower end inside the reactor body, wherein the upper circulation coil and the lower circulation coil respectively include an independent heat exchange device to realize a circulation of a heat transfer medium in the upper circulation coil and the lower circulation coil:
N temperature control pipes are spacedly disposed inside the reactor body and between the upper circulation coil and the lower circulation coil, wherein the N temperature control pipes are configured to form a vertical temperature gradient in the reactor body, wherein N is a positive integer; and
each of the N temperature control pipes also includes an independent heat exchange device to realize the circulation of the heat transfer medium in the each of the N temperature control pipes.
