The multi-component thermal fluid generator utilizes the high-pressure combustion injection mechanism. High-pressure air and natural gas/diesel are fully burned under high-pressure and closed conditions to generate high-temperature and high-pressure carbon dioxide, nitrogen and water vapor. The high-temperature flue gas is mixed with water to form a multi-component thermal fluid, which is directly injected into the oil layer.
New and old areas of shallow heavy oil, as well as hot water flooding, hot water combined flooding, gas-water alternating flooding and other technologies applications.
It can be expanded to steam composite flooding, SAGD, multi-assisted SAGD and so on.
High thermal efficiency: fuel and air are directly burned and soft water is directly vaporized to produce steam. High-temperature and high-pressure carbon dioxide, nitrogen and water vapor are directly injected into the oil layer, with a thermal efficiency of over 97.5%.
Low steam-oil ratio: The ratio of the generated multi-component thermal fluid equivalent to the crude oil production is low. Currently, some application performance has reached 0.23:1.
Zero carbon emission: All combustion products are injected into the formation and oil layer, achieving the goal of zero carbon emission in the injection process.
Strong adaptability: All multi-element thermal fluid equipment adopts skid-mounted equipment, which has high installation efficiency and low engineering investment.
High recovery rate: After multiple rounds of multi-component thermal fluid huff and puff, the theoretical recovery rate of multi-component thermal fluid huff and puff can exceed 52% at a well spacing of 70m.
Xinjiang Oilfield, Intercontinental PM Oilfield, Kazakhstan KBM Oilfield, Kazakhstan Emba Oilfield.
In the KMK oilfield in Kazakhstan, through more than 20 wells of multi-component thermal fluid throughput tests in more than a year, it was proved that the average single-well production of multi-component thermal fluid throughput increased to 2.5 times that of the original steam throughput, and the oil-gas ratio increased from 0.2 to 0.48.
A total of 15 wells (12 vertical wells and 3 horizontal wells) and 22 well-times were implemented. After the measures were taken, the average daily oil production of a single well increased by 4.3t/d, the single well oil production increased by 699t, and the cumulative oil production increased by 13,298.4t.
