Zusammenfassung: | The utility model belongs to the technical field of petroleum composite pipes, and particularly relates to a non-metal continuous pipe for geothermal exploitation. A nonmetal continuous pipe for geothermal rock hot exploitation comprises a plurality of composite pipe sections and connectors connected between the composite pipe sections, each composite pipe section is of a multi-layer structure and sequentially comprises an anti-corrosion inner pipe, a cable layer, a reinforcing layer, a heat preservation layer and an anti-abrasion outer pipe from inside to outside, a plurality of cables are arranged in each cable layer, and the cable layers are connected with the connectors. The cable layer and the corrosion-resistant inner pipe are bonded through hot melting, the heat preservation layer and the abrasion-resistant outer pipe are bonded through hot melting, the connector comprises a non-metal connector inner pipe, the two ends of the non-metal connector inner pipe are bonded with the composite pipe sections th |
