Abstract
The present invention relates to methods for the extraction of heavy oils and oil sands from oil reservoirs and methods for the extraction of bitumen from oil sands and oil shale. The methods comprise an injection of a solvent comprising sodium silicate, the use of thermal technology, and/or the use of gas injection into an oil reservoir to enhance the extraction of oil from the oil reservoir. Further, methods of extracting bitumen from oils sands using a solvent comprising sodium silicate are also provided.
Description
Invention field
The present invention relates to the extraction of heavy oil.
Background of invention
All publications are all introduced for referencely herein, and its introducing degree each independent publication or patent application seemingly shows clearly and individually by the same with reference to introducing.Following description comprises understanding Useful Information of the present invention.This is not to admit that any information provided herein is prior art or relevant with present claimed invention, or clearly or any publication of reference impliedly be prior art.
Oil-sand (being also referred to as Tar sands) is mainly to be the mixture of sand grains, pitch and water.Every oil-sand has three layers: surround " encapsulated layer " of the water of granule, pitch surrounds this water and forms skin.Therefore, be called " glossy wet " otherwise and it also can be " water-wet ".Other materials, for example clay may exist among sand, pitch and the water.Pitch in its virgin state, is heavy viscous crude oil, and it contains a large amount of sulphur usually.As everyone knows, the pitch of Utah State discovery contains the sulphur of low amount usually.
Resinous shale is the sedimentogeneous rock that contains solid bituminous materials.When this rock was heated, pitch can discharge by pyrolytic process.
There are two kinds of technology to be used for extracting pitch at present: to carry out underground (sub-terrain) exploitation with truck ground (terrain) exploitation, pulverizing and processing with by thermal recovery; For example use steam.For surface mining, a large amount of open-air pits and associated extraction facilities have been set up from sand, to isolate pitch.For sub-terrain operations, carry out drilling well and injecting steam to add heated bitumen, it is flowed and from well, pump.
Pitch is sold with two kinds of common form: raw material and synthetic crude (" SCO ").In its raw material form, pitch and thinner blend to be to produce " bitumen blend ", because in its raw material form, pitch is thickness and can not transporting by conventional pipelines too.The thinner that uses for this blend is heavy-gravity hydrocarbon not too normally, more generally very light natural gas condensates (C5+ or " more than the pentane ").In addition, thinner is the expensive light crude of fully handling.Bitumen blend is sold to refinery, and competes with conventional heavy oils.As SCO, pitch is by upgrading.SCO also is sold to conventional refinery, and competes with medium oil of tradition and light oil.
In addition, crude oil development and production can comprise three phases: primary recovery, secondary recovery and tertiary recovery (being also referred to as strengthening mining).Primary recovery relates to the natural pressure or the gravity that utilize oil reservoir and enters pit shaft and use lift technique (for example, pump) so that oil is taken to the surface to promote oil.Yet, in this stage, only produce the oil in the oil reservoir of little per-cent (about 10%) usually.In secondary recovery, adopt such as injecting water or gas to replace oil and oil to be pushed to the technology of pit shaft.Secondary recovery can cause the crude oil of the about 20%-40% of extraction.Three times or the oil recovery technique strengthened have used and can cause the crude oil recovery ratio of about 30%-60%.
In the oil recovery of strengthening, use carbonic acid gas (CO
2) obtained certain success.Yet, inject CO
2Always because gas refers to that (gas fingering) and gravity segregation cause oil displacement efficiency poor.Compare high-density CO with water or oil viscosity
2Viscosity low, cause mobility ratio height, thereby cause oil displacement efficiency poor.It is CO that water and gas alternately inject
2Be used for controlling mobile common method in the air-flow.But, water and CO
