| titleOfInvention | A kind of oil shale underground in situ exploitation heat-insulation and heat-preservation heat injection pipe |
| abstract | The utility model discloses a kind of oil shale underground in situ exploitation heat-insulation and heat-preservation heat injection pipe, heat injection pipe and insulation threeway are constituted in several ground heat injection pipes, well head heat injection pipe, several wells, several ground heat injection pipes are threaded in insulation threeway two ends respectively, well head heat injection pipe is fixedly installed on heat injection pipe screw thread in insulation threeway lower end, well and is connected to well head heat injection pipe lower end；During work, it is heated to the gas of a certain temperature or liquid the heat injection pipe along along ground heat injection pipe, well head heat injection pipe and well and is fed sequentially into oil shale or pay sand position, the heat oil shale layer or pay sand carried by high-temperature gas or liquid carries out lysisin situ and exploit shale oil gas.The utility model is simple in construction, convenient disassembly, thermal loss is reduced, the energy is saved, the stress suffered by solder joint and displacement is reduced, extend the service life of ground heat injection pipe, each heat injection pipe is connected through a screw thread, and reduces the use of joint, reduces required cost, maintenance maintenance is convenient, improves operating efficiency. |
