COMPREHENSIVE EXPERIMENTAL EXPLOITATION SYSTEM HAVING LARGE-SCALE, FULL-SIZE, THREE-DIMENSIONAL EXPLOITATION WELL

摘要

A comprehensive experimental exploitation system having a large-scale, full-size, three-dimensional exploitation well, comprising: a reaction kettle (1), used to prepare a natural gas hydrate sample and realistically simulate an natural gas hydrate accumulation environment in a sea floor sedimentation layer, the reaction kettle comprising a reaction kettle body (10) and an upper kettle cover (11) mounted on an upper end face of the reaction kettle body, and a lower kettle cover (12) mounted on a lower end face of the reaction kettle body; a gas injection module (2), used inject a quantity of a gas into the reaction kettle during hydrate synthesis a liquid injection module (3), used to inject a quantity of a liquid into the reaction kettle during hydrate synthesis; a temperature control module, used to control the temperature of the reaction kettle; and a data collection, processing, and display module (4), used to collect, store, process, and display data during performance of testing in the test exploitation system. The present system is able to prepare a natural gas hydrate sample, and carry out experimental simulation research on exploitation techniques such as depressurization and heat injection, and investigate hydrate decomposition, gas and liquid seepage, heat transfer, and sediment stabilization in an exploitation process.
