Abstract
A medium-pressure steam-injection boiler comprises a pumping operation room, an auxiliary machinery operation room, a radiation zone, a horizontal-type convection zone, and a chimney. The auxiliary machinery operation room, the radiation zone, the horizontal-type convection zone and the chimney are connected in order. A boiler water-feeding pump is installed inside the pumping operation room. A burner is installed inside the auxiliary machinery operation room. A heat exchanger is installed at the lateral side of the radiation zone. The utility model can work outdoor in high latitude severe cold areas, reduces the investment of fixed construction of ground fixed construction, reduces the overall height to facilitate the installation and relocation, and is suitable for the steam injection process during the late stage of heavy oil and light oil recovery.
Description
One, technical field
The utility model relates to injection boiler, is a kind of middle pressure injection boiler furnace, and move suitable especially winter in the open.
Two, background technology
Uphole steam generator is the visual plant of oil-field thick-oil and the exploitation of thin oil later stage.Uphole steam generator mainly is made of radiant section, convection section, changeover portion, burner and boiler accessory machinery, and floor space and weight are bigger.For satisfying the operational management requirement of high latitude severe cold area uphole steam generator in winter, must build bigger heating plant central heating supply, fixedly construction investment is bigger to cause ground, and uphole steam generator is difficult for integral moving.Because central heating supply, individual well steam injection technology pipeline is longer, and heat-energy losses is bigger.Along with the paces of oil field rolling development are accelerated, how the increasing that heavy oil block exploitation risk investment is built reduces the fixed investment scale, the cost of investment of reducing risks, reduce simultaneously and annotate the vapour heat energy loss, improve the recovery ratio of zones and surface areas for joint exploration and exploitation viscous crude, cause everybody concern day by day.On-the-spot requirement to uphole steam generator is: (1) uphole steam generator can move at the high latitude severe cold area winter in the open, thereby reduces fixedly construction investment scale of ground; (2) reduce the injection boiler whole height, reduce the injection boiler overall weight; (3) be convenient to install and resettlement, and can realize that closely steam injection technology requirement of heavy crude heat extraction (4) improves insulation construction, reduce injection boiler external surface heat dissipation capacity; (5) environmental protection, safe, energy-conservation.
Three, summary of the invention
The utility model provides a kind of middle pressure injection boiler furnace, has overcome the deficiency of above-mentioned prior art, and it suits to move in the open and be easy to move winter at high latitude area.
The technical solution of the utility model realizes by following measure: pressure injection boiler furnace in a kind of, it comprises pump house operation room, subsidiary engine operation room, radiant section, horizontal convection section and chimney, subsidiary engine operation room, radiant section, horizontal convection section and chimney are linked together successively, at the pump house operation room boiler feed pump is installed, at the subsidiary engine operation room burner is installed, heat exchanger is installed at the radiant section sidepiece.
Be further optimization and/or improvements below to above-mentioned technical solutions of the utility model:
The air intlet of said burner can be equipped with air preheater.
Above-mentioned subsidiary engine operation room can be equipped with power distribution cabinet.
Above-mentioned subsidiary engine operation room can be equipped with control valve.
