Sand control pipe column for natural gas hydrate reservoir exploitation and well completion and exploitation method

The invention provides a sand control pipe column for natural gas hydrate reservoir exploitation and a well completion and exploitation method, and belongs to the technical field of natural gas hydrate development. The sand control pipe column comprises a production casing pipe, an electric submersible pump and a sand control screen pipe are arranged in the production casing pipe, and the sand control screen pipe is located below the electric submersible pump; and a plurality of kerfs are formed in the lower sleeve wall of the production sleeve and located below the sand control screen pipe. In order to solve the problem of serious formation sand production in the natural gas hydrate exploitation process, the mode that the sand control screen pipe and the kerfs are staggered is adopted, sand bodies are prevented from making direct contact with the sand control screen pipe, meanwhile, a small amount of output will be reduced due to the fact that the sand bodies enter a production sleeve due to the reasonable s
