Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

Bituman (hereinafter referred to as bitumen) recovered from oil sand, one of the petroleum resources, has been considered only as a spare alternative resource due to poor quality in the past, but the oil obtained from the bitumen is now compared with that obtained from crude oil. Therefore, it is sufficiently competitive in terms of qualitative and cost, and research and development for this is being conducted in various ways.

Here, the oil sand is also called tar sand and is a sandstone layer containing 10 to 12% bitumen, which is a heavy hydrocarbon with high viscosity. Therefore, oil sands exist by mixing sand, water, and mud as well as bitumen.The bitumen produced from oil sands is an oil deficient in hydrogen, and bitumen is extracted through various processes and then converted into synthetic crude oil through an additional refining process. After being created, it is moved to another area.

It is a method of extracting bitumen from oil sand. If the depth of the reservoir is less than 150ft, remove various stones or soil on the oil sand, dig up the oil sand, and then move to an extraction plant with hot water at 175°F. Mix with and extract bitumen.

Here, in order to produce about 1 barrel of bitumen, about 2 tons of oil sand, 2 to 5 barrels of clean water, and 250 ft ³ of natural gas are required. Bitumen produced from oil sands is converted into synthetic crude oil through a refining process, and then separated into gasoline, heavy oil, and diesel.

As described above, among the methods for extracting bitumen from oil sands, the most widely used method is the underground recovery method (SAGD).

The underground recovery method (SAGD) is a technology in which a pipe is inserted into the ground to induce steam in order to mine oil sand in the deep ground, and then the bitumen is separated from the oil sand mass through heat and then raised to the ground. The process of producing crude oil in the oil sand plant using the oil consists of the following steps.

Referring to FIG. 1, the plant equipment includes an injection pipe P1 and a product pipe P2 installed in the ground, a first well pad module 100 for supplying steam, and a second well pad module 200 for recovering oil. And a well pad control module 300 in charge of various controls.

Others include a cleaning plant (W) and a storage plant (S).

Firstly, steam is generated, the injection pipe (P1) is put into the ground, and the generated steam is introduced to collect gas or oil when it comes up.

The collected components can be classified into oil or gas, among which water or mud contained in the oil, and other oil components are separated through a separator, and the extracted water components are treated through oiling and production water treatment. , Gas components proceed to the process of removing moisture or sulfur.

The water treatment facility is designed to undergo a water treatment process by sedimentation and filtration, and the facility for each step is a facility that requires precise control, and the ratio of oil or solid to be removed according to the water treatment process performed in each step is different. .

Here, the steam produced through the steam generator is supplied through an injection well installed to an oil sand deep underground through the injection facility of the well pad system, and the viscosity of the separated bitumen is reduced through the steam. It is collected through.

This well pad system is installed in the oil sand area buried in the underground area, and in the process of melting the oil sand by spraying high-pressure steam using the well pad system, some of the water vapor leaks to the outside and contaminates the surrounding area. There is a disadvantage, especially in the case of bitumen mining equipment buried underground, after all the oil sands have been mined, they must be disposed of as they are or removed and reassembled by moving them to another oil sand area, so work efficiency and economics are poor. There was a problem.

In addition, oil recovery enhancement (EOR) facilities with various structures are applied for the production of heavy substances in oil fields. Most EOR facilities inject steam, CO₂, N₂, and polymer into the injection well to reduce heat and heat to the reservoir with oil. Produces oil under pressure.

Usually, the production of crude oil by natural ejection under pressure in the oil bed is called primary recovery.The crude oil produced by the primary recovery accounts for only 15% of the reserves, and the rest is by injecting gas or water into the well. The crude oil is recovered and this is called a secondary process.

Crude oil remains in the reservoir even after the second recovery.Water vapor, surfactant, hydrocarbon gas, carbon dioxide gas, etc. are injected into the oil layer to recover a part of the gas and crude oil in a completely mixed state. It is called.

Since the crude oil recovered from the ground to the surface is mixed with gas and water, the gas and water are first separated. The gas is again separated from the crude oil and water, and impurities such as hydrogen sulfide and carbon dioxide are removed. It is recovered and passed on to the next process (Desanding, Separator, etc.).

At this time, the steam injection used to inject a large amount of high-pressure steam into the oil reservoir of the stratum requires a large air compressor, a water supply pump, an oil-water separator, etc., which increases manufacturing cost.

In addition, since the steam generating device must be precisely assembled and manufactured as the Cab area including the burner and the Radient & Convection Section are integrated, it is difficult to assemble in the field where various assembly and measuring equipment are not equipped, and it is difficult to transport large facilities to the site. Therefore, the problem of delayed production was exposed due to the inability to secure a plant proportional to the oil field.

The present invention is as shown in Figure 1,

It relates to a device for injecting steam and heat carrier, which is an EOR facility composed of several device combinations, and consumes energy required to recycle water by first removing the flow rate of the supplied water that is collected by configuring an evaporator combination in addition to the steam generator and injector. By reducing the reduction and further improving the productivity of the EOR facility, the injection well pad of the reservoir is configured in a modular package type to provide a high-pressure, high-temperature steam production and injection device.
