Produce heavy hydrocarbon for producing the device of steam, system and method.
The exploitation in oil field generally occurs in three phases.The first stage of oil field development is once to open
Adopt.During primary recovery, one or more holes are drilled down in hydrocarbon reservoir from surface.In underground
Present in hydrocarbon reservoir, pressure is forced through well to surface hydrocarbon.Primary recovery continues, until hydrocarbon stores up
Insufficient pressure in Ceng is to be forced through well to surface hydrocarbon.Typically, the initial oil in reservoir
Only 5 to percent 15 percent can be produced during primary production phase.
The second stage of oil field development is secondary recovery.During secondary recovery, various technology can be used
In from the reservoir recovery of hydrocarbons with the pressure exhausted.It is exuberant that a kind of technology is referred to as reservoir, relates to injection
Fluid such as water is to increase reservoir pressure, so that hydrocarbon is forced through well to surface.A kind of selectable
Technology is referred to as gaslift, relates to injected gas such as carbon dioxide to reduce the overall of fluid in well
Density.Then strata pressure be enough to the fluid forces of less density through well.Sometimes, pump can
Extract to surface from hydrocarbon reservoir for oil.Typically, only percent the 20 of the initial oil of reservoir
Can be extracted by primary recovery and secondary recovery to percent 40.
The phase III of oil field development is tertiary recovery, oil exploitation (EOR) also referred to as strengthened.
After secondary recovery, the big percent of hydrocarbon keeps being trapped in reservoir.During EOR,
Various methods are used for increasing the mobility of oil to increase extraction.The most common method of EOR is steam
Injection.Typically, steam uses the steam generator on surface to produce, and it is often steam power plant
A part.Steam is then passed through well and is injected in reservoir, and in reservoir, steam adds deep fat, thus subtracts
Lack its viscosity and make it easier to extract.Current based on steam oily recovery method is due to heat and pressure
Power loss is only for about 2,500 feet effectively.Surface production of steam the most undesirably produces the biggest temperature
Room gas discharge.
A kind of selectable EOR method is that carbon dioxide is exuberant, and wherein carbon dioxide is injected into oil
In reservoir, in reservoir, carbon dioxide mixes with oil, reduces its viscosity and makes it easier to extract.
Carbon dioxide is exuberant is particularly effective in ratio 2,000 foot of deep reservoir, wherein carbon dioxide
In supercriticality.Other selectable EOR methods include injection reduce viscosity and improve to
The fluid of the flowing in hydrocarbon reservoir.These fluids can include gas blendable with oil, air, oxygen
Gas, polymer solution, gel, surfactant and polymer preparation, alkali, surfactant and polymer
Preparation or microorganism formulation.The method of current EOR typically allow reservoir oil the most additionally
5 to percent 15 percent be produced.
The amount of minable hydrocarbon is determined by multiple factors, including the degree of depth of reservoir, the permeability of rock,
And the intensity of natural driving, such as gas pressure, from the pressure of the water adjoined or gravity.One
Individual important factor is the viscosity of the hydrocarbon in reservoir.The viscosity of hydrocarbon extensively from light to weight
's.Lighter oil typically results in higher extraction ratio.In yet another aspect, heavy oil, Colophonium and first
Alkane hydrate is full-bodied or solid, and the hardly possible oil producing method using routine carries
Take.Api gravity that heavy oil is typically classified as having about 10 to about 20 and greater than about 100cP's
The oil of viscosity.Colophonium be typically have less than about 10 API and the viscosity of greater than about 10,000cP
Semisolid or hydrocarbon solid material.In methane hydrate is the crystal structure being trapped in water of methane
Solid form.Heating methane hydrate can discharge the methane of gaseous state from its lattice structure.
2,500 feet of lower sections and the heavy oil of the full degree of depth and bitumen reservoir in offshore can not make by land
Produce with current steam technologies.Study according to national oil and energy research association (NIPER),
