Description

A mobile steam injection boiler and its moving method

technical field

The invention relates to the technical field of heavy oil development, in particular to a mobile steam injection boiler and a moving method thereof.

Background technique

The technical parameters of the existing steam injection boiler are: rated evaporation: 23t/h; rated steam pressure: 17.2MPa; rated steam temperature: 353℃; steam dryness: 80%; size: 27750×4110×8470mm (including chimney); Fuel: oil, gas; control mode: PLC+touch screen. The structure of the steam injection boiler is shown in Figures 1 and 2, including the boiler body, water-water heat exchanger, burner 04, blower 05, boiler operation panel 06 (ie, automatic instrument) and plunger pump 07. The boiler body includes a radiation section 01, a transition section 02 and a convection section 03. The radiation section 01 is a cylindrical structure, and the heating surface adopts a serpentine reciprocating structure. 12500mm. The transition section 02 is a high-temperature flue gas turning area. The transition section 02 is 4680mm long, and there is no heating surface arranged inside, and the outer surface temperature is the highest. The convection section 03 is located in the low temperature area of the flue gas, and its function is to further reduce the temperature of the flue gas and improve the thermal efficiency of the boiler. Burner 04 is a North American direct-blowing dual-fuel burner, the burner section is 5500mm long, and the rest of the pump section is 5070mm.

Traditional steam injection boilers, especially large-scale steam injection boilers with a rated evaporation of 23t/h, are all skid-mounted fixed structures. They are fixedly installed in the workshop for steam injection through the steam injection pipe network, and cannot be moved casually. However, with the development of the old heavy oil block, the steam injection volume has decreased, so that some 23t/h steam injection boilers are idle and out of service. However, according to the reservoir development plan, the newly developed heavy oil block requires a lot of steam injection. The steam injection task was originally undertaken by the 11.2t/h and 9.2t/h active boilers. The boiler evaporation is low, the steam injection rate is slow, and the single well steam injection time long, which greatly affects the oil production rate of this block. If the 23t/h steam injection boiler is rebuilt in the new block, the construction cost will be higher; if the steam injection boiler in the old block is relocated to the new block, the factory building needs to be dismantled, and the steam injection boiler shall be hoisted and relocated by a large crane. It will cost about 8.13 million yuan to relocate a steam injection boiler and build a new steam injection station, which is a relatively large investment.

During installation, the components of the stationary steam injection boiler in the old block are disassembled as described above. The boiler operation panel 7, burner 5, blower 6, radiant section 1 and water-water heat in the first module The exchangers 4 are correspondingly connected to each other in advance, and the individual modules are installed on the respective transport vehicles. When in use, each module can be transported to the working position of the newly developed heavy oil block directly through each transport vehicle. The first module is still installed on the first transport vehicle 9 without removing it, and then the second module and the third module , the fourth module and the fifth module are hoisted to the ground by a crane, the convection section 3 is installed above the tail of the radiation section 1, and then the modules are connected by corresponding pipelines, which can be used directly, realizing the fixation of the old block. move and reuse the steam injection boiler. By installing the five modules on the five transport vehicles, they can be moved to the designated position through the conveying action of each transport vehicle, which is simple and convenient, especially for a steam injection boiler with a rated evaporation of 23t/h. The vehicle-mounted mobile transformation of the idle steam injection boilers in the old blocks only requires an investment of 2.26 million yuan, which can reduce the investment cost by 5.87 million yuan.

Further, in order to facilitate the installation and fixation of each module, the first module is installed on the first transportation vehicle 9 through the first chassis, the second module is installed on the second transportation vehicle through the second chassis, and the third module is installed through the first chassis. The third chassis is mounted on the third transport vehicle, the fourth module is mounted on the fourth transport vehicle through the fourth chassis, and the fifth module is mounted on the fifth transport vehicle through the fifth chassis.

It can be understood that the boiler operation panel 7, the blower 6 and the shell of the radiant section 1 in the first module are fixed on the first chassis, and the water-water heat exchanger 4 is generally arranged on the side of the radiant section 1. In the prior art, the method of arranging it on the upper part of the radiation section 1 can ensure that the pulling is not too high. For other supporting equipment other than those listed above (such as expansion container, discharge water tank, discharge water pump, water pump operation room, etc., the specific structure is the prior art), it is also installed on the fifth transport vehicle as a part of the fifth module for transportation. Each module and the chassis form a whole. After being transported to the working position, they can be removed from the transport vehicle by a crane. At the same time, the second module and the second chassis can be disassembled, so that the convection section 3 can be installed on the radiation section 1. above the tail.

In actual use, a suitable transport vehicle is selected according to the size of each module. In this embodiment, the first transport vehicle 9 is preferably used as a trailer, the second transport vehicle, the third transport vehicle, the fourth transport vehicle and the fifth transport vehicle. Both are trucks. Among them, in this embodiment, after the first module is installed on the trailer, the overall size is 18500 × 4000 × 4800 m. After transporting to the designated position, the trailer head of the trailer can be driven away alone, and the wheels of the trailer and the tires at the bottom of the wheel remain undisturbed. At the same time, a support leg 91 will be added at the bottom of the chassis to ensure that the first module is more stably supported on the bottom surface through the chassis. Each truck can be transported to the designated position and the modules can be removed, and the steam injection boiler can be used when it needs to be moved again later.

Further, since the steam temperature of the steam outlet is the highest temperature of the circulating water, in order to prevent the steam temperature from causing the tube burst phenomenon to the first tube bundle 11 in the radiant section 1, the first module also includes a The high dry section 2 and the convection section 3 are installed above the high dry section 2. A first tube bundle 11 arranged in a serpentine reciprocating arrangement is arranged in the radiation section 1 , and a second tube bundle 21 arranged in a serpentine reciprocating arrangement is arranged in the high trunk section 2 . The outlet end of the first tube bundle 11 is connected to the inlet end of the second tube bundle 21, and the outlet end of the second tube bundle 21 serves as a steam outlet.

The first tube bundle 11 is composed of a plurality of horizontal tube bundles and curved tubes connected in series, and the structures of the radiation section 1 and the first tube bundle 11 inside are all in the prior art. The shells of the convection section 3 and the high dry section 2 are both rectangular structures, and the two are connected up and down. In this embodiment, the overall dimensions of the shells of the convection section 3 and the high dry section 2 are 4312mm×2373mm×1400mm. Compared with the method of using the outlet end of the first tube bundle 11 as the steam outlet in the prior art, in this embodiment, the steam outlet is moved backward, so that the circulating water remains liquid in the first tube bundle 11 of the radiation section 1, It flows into the high dry section 2 and then becomes water vapor. Since the flue gas temperature at the high dry section 2 is relatively low, it can avoid the pipe bursting at the steam outlet, and the use is safer.

In practical applications, in order to facilitate processing and installation, the radiant section 1 includes a horizontal cylindrical shell 12, a cut 121 is provided above the tail of the shell 12, and a mounting frame 122 is provided at the cut 121. The lower end of the high trunk section 2 Mounted on the mounting frame 122 .

When transforming the original radiant section 1 of the fixed steam injection boiler in the old block, as shown in Figure 5, the original horizontal cylindrical structure is still retained, and the dimensions of the front and rear panels of the casing 12 are kept unchanged ( length 12500mm), and then cut off part of the shell 12 from the rear end plate forward (ie, cut off the dotted frame part shown in Figure 2), the length dimension is about 4500mm long, the width is the original convection section 3 width (about 2400mm), and the The original 56 horizontal tube bundles were reconstructed, and the 34 horizontal tube bundles below the radiation section 1 remained unchanged, and the remaining 22 horizontal tube bundles were intercepted. After the interception, the length of this part of the horizontal tube bundles became 6965mm. The cut-out portion on the housing 12 constitutes the above-mentioned cut-out 121, and the part of the radiation section 1 below the cut-out 121 is equivalent to the function of the transition channel of the transition section. The structure of the installation frame 122 is shown in FIG. 6 . Of course, the shape of the installation frame 122 can also adopt other shapes, which is convenient for subsequent connection with the high trunk section 2 .

Further, the convection section 3 is provided with a serpentine reciprocating third tube bundle 31, the water-water heat exchanger 4 includes an inner tube and an outer tube sleeved outside the inner tube, and the outlet end of the plunger pump 8 is connected to the outer tube. The water inlet end of the outer tube is connected with the water inlet end of the third tube bundle 31, the water outlet end of the third tube bundle 31 is connected with the water inlet end of the inner tube, and the water outlet end of the inner tube is connected with the inlet end of the first tube bundle 11. Water connection.

The third tube bundle 31 includes a light tube 311 and a finned tube 312 disposed above the light tube 311. The water inlet end of the finned tube 312 serves as the water inlet end of the third tube bundle 31. The water inlet end of the light pipe 311 is connected with the water outlet end of the third tube bundle 31 . The burner 5 is arranged at the head of the radiation section 1 , and the burner 5 is connected with the blower 6 .

When in use, the burner 5 can spray flame into the furnace inside the radiant section 1, and the first tube bundle 11 in the furnace receives heat and transfers it to the circulating water in the first tube bundle 11, so that the water evaporates into water vapor, and then from The outlet end of the first tube bundle 11 enters into the second tube bundle 21 of the high dry section 2, and is then discharged into the downhole heavy oil reservoir from the outlet of the high dry section 2. At the same time, when the flame is injected into the furnace, the high-temperature flue gas generated by the combustion of the fuel will flow directly along the furnace of the radiant section 1 into the high dry section 2, and then flow into the convection section 3. At this time, the flue gas will flow into the third tube bundle 31. The temperature of the boiler feed water in the third tube bundle 31 increases, and the temperature of the flue gas decreases accordingly. Furthermore, the waste heat of the flue gas can be fully utilized to heat the circulating water flowing into the first tube bundle 11 of the radiant section 1, so that the heat required to evaporate the circulating water in the first tube bundle 11 into water vapor is reduced, and the burner is greatly reduced. 5 fuel consumption, which improves the thermal efficiency of the steam injection boiler.

The boiler feed water is pumped into the outer tube of the water-water heat exchanger 4 through the plunger pump 8, and at the same time, the inner tube receives the boiler feed water with a higher temperature after the outlet end of the third tube bundle 31 is exchanged by the heat of the flue gas in the furnace. There is heat exchange due to the large temperature difference between the inner tube and the outer tube, which reduces the temperature of the water in the inner tube and increases the temperature of the water in the outer tube. The boiler feed water in section 3 is heated, so that the inlet water temperature of the third tube bundle 31 is raised and exceeds the dew point temperature of the flue gas, so as to prevent the condensation of water vapor and sulfur dioxide in the flue gas due to the low inlet water temperature, thereby producing sulfuric acid and causing convection in section 3. Corrosion of finned tubes 312. The water at the outlet end of the inner tube will flow into the first tube bundle 11 of the radiant section 1 .
