Oilfield Steam Boiler: The Complete Guide for Importers and Buyers

How to improve the defects of the fixed steam injection boiler in use?

Oilfield Steam boiler, also known as wet steam generator, is a professional steam injection equipment for heavy oil production in oil field. It uses the produced high-temperature and high-pressure wet steam to inject into the oil well to heat the crude oil in the reservoir to reduce the viscosity of heavy oil, so as to increase the fluidity of heavy oil and greatly improve the recovery of heavy oil.

It is a horizontal once-through water tube boiler, which is designed as a liquid (gas) combustion type. It uses the heat energy released by fuel combustion to heat a certain amount of water into wet saturated steam or superheated steam with a certain pressure, temperature, and dryness.

heavy oil thermal recovery

The superheated oilfield steam injection boilers in the existing technology are all fixed steam injection boilers. At present, there are the following problems in the use process:

(1) The superheated steam injection filter must be fixed and installed on the steam injection site by using the civil engineering foundation, and the position is relatively fixed and can’t be moved at will; the supporting steam injection pipe network is also a fixed steam injection pipeline system, so the steam injection boiler and steam injection pipe network can’t be moved easily;

in order to change the steam injection location, the civil foundation of the boiler needs to be remade in the new steam injection site, and the steam injection pipe network also needs to be laid again, resulting in high cost of use;

(2) When the fixed steam injection boiler is installed in place, the steam pipe inside the boiler body needs to be reconnected and welded, resulting in the increase of installation cost;

(3) the fixed steam injection boiler cannot be used in the steam injection wells which are relatively scattered and far away from the well site, so it can’t meet the needs of various environments.

fixed steam injection boilers

In view of the above problems, Sanjack company invented a superheated steam injection boiler to alleviate the technical problems in the existing technology, such as the high installation cost and unable to meet the requirements of various environments used by using the fixed steam injection boiler.


The superheated boiler comprises a mobile device, a boiler body, and a steam-water separator skid; the mobile device is connected with the boiler body, and the boiler body is detachably connected with the steam-water separator skid so that the boiler body and the steam water separator skid can be transported separately; when the boiler is in operation, the boiler body and the steam-water separator skid are connected as a whole.

When it is necessary to transfer the steam injection well site, the boiler body is transported and transferred by mobile device, and the steam water separator skid is transported and transferred by vehicles. It can alleviate the technical problems existing in the prior art, such as high use cost, high installation cost, and inability to meet the use in a variety of environments; The installation and use of the mobile superheated steam injection boiler are realized, which makes the superheated steam injection boiler easy to be popularized and used.

Specific embodiments

As shown in Fig. 1-fig. 3, the superheated oilfield steam injection boiler provided in this embodiment includes: mobile device 100, boiler body 200 and steam water separator skid 300;

The mobile device 100 is connected with the boiler body 200, and the boiler body 200 is detachably connected with the steam water separator skid 300, so that the boiler body 200 and the steam water separator skid 300 can be transported respectively.


It should be noted that the superheated boilers in the prior art all adopt fixed steam injection boilers. Due to the limitations of the application environment of the fixed steam injection boiler, it can not meet the existing flexible use environment.

The superheated steam injection boiler provided in this embodiment, when the superheated steam injection boiler is in overall operation, The first whole formed by the boiler body 200 and the mobile device 100 and the two parts formed by the steam water separator skid 300 form a whole by detachable sealing connection;

When it is necessary to transfer the steam injection well pad, the connecting part between the two parts is disassembled, the boiler body 200 uses the mobile device 100 to realize road transportation / transfer through the mounted vehicle head, and the steam water separator skid 300 is transported / transferred by vehicles.


Alternatively, the mobile device 100 can adopt a variety of ways, such as a vehicle body with a box or a flat trailer. Preferably, the mobile device 100 adopts a flat trailer, and the boiler body 200 is fixedly connected to the flat trailer. When transportation and transfer are required, the transportation of the boiler body 200 can be completed by connecting the front of the vehicle with the mobile device 100.
