Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Oil well hot fluid intelligent heater shown in Figure 1, this device is by heater 1, HTHP Thermal insulating rubber tube 2, four-way 3, concentric inside holding pipe 4, variable buckle 5, natural gas line 6, power line 7, solid sucker rod short circuit 8, polished rod sealer 9 forms, the electric system of heater 1 is powered by power line 7, the source of the gas of heater 1 is provided by natural gas line 6 by oil well, heater 1 access is connected with HTHP Thermal insulating rubber tube 2, HTHP Thermal insulating rubber tube 2 is connected with four-way 3 access, four-way 3 top and solid sucker rod short circuit 8 connection suspension are taken out, four-way 3 bottom is connected with concentric inside holding pipe 4, concentric inside holding pipe 4 is connected with variable buckle 5, variable buckle 5 is connected with oil pump piston 10, polished rod sealer 9 is enclosed within concentric inside holding pipe light pipe and is connected with wellhead sealing.
Heater 1 can be various forms of structure, as long as can meet fluid heating power needs, and can keep oil wells in field safety, environmental protection.The new forms of energy heater etc. that heater 1 is generally combustion heater, coal heater, electromagnetic heater, solar heater, biologic grain heater and newly develops.
Concentric inside holding tubular structure has two kinds, and they are split type and monolithic.
Shown in Figure 2 is split type concentric inside holding pipe schematic diagram, split type concentric inside holding pipe it by concentric inside holding pipe, concentric inside holding seal of tube circle 102, pipe 105 in insulation, interior pipe slipper seal support 106, interior pipe fixed support 107 forms, in insulation, pipe 105 is by interior pipe, insulation layer 104, topping 103 forms, interior pipe slipper seal support 106 external screw thread is connected and fixed with concentric inside holding pipe pin end internal thread, endoporus is connected with pipe in insulation, interior pipe fixed support 17 external screw thread is fixed with concentric inside holding pipe box end internal thread, endoporus is welded and fixed with pipe 105 other end in insulation, many when connecting, while the outer bar box and pin of concentric inside holding pipe connects, in insulation pipe 105 also grafting be simultaneously tightly connected, the long distance inner-outer circulation path needed for Construction designing.
Shown in Figure 3 is monolithic concentric inside holding pipe schematic diagram, it is made up of pipe 203 in concentric inside holding pipe outer tube 201, outer tube sealing ring 202, continuously insulation, wrap up heat insulating material 204 outside pipe 203 in insulation, and which constitute a complete insulation inner tube material.First concentric inside holding pipe outer tube 201 is installed in well during execute-in-place, and then is installed in outer tube 201 with special hoist by being incubated interior pipe continuously, form concentric inside holding tubular structure with outer tube, form fluid circulation channel.
The heater 1 of this device is installed on beyond well head 15m, on the working platform in the liftoff explosive place of more than 0.4m non-flammable.Concentric inside holding pipe 4 is arranged in oil pipe, and bottom is connected with oil pump piston 10, and top is connected with four-way 3, and four-way 3 top is hung by pup joint of sucker rod 8 and takes out, and access, four-way 3 side is connected with heater 1 access by HTHP Thermal insulating rubber tube 2.
