Description
Technical field
The present invention relates to a kind of high temperature foam stabilizer and preparation method and application, more particularly to a kind of thick oil steam drive
Anti- channeling high temperature foam stabilizer and preparation method and application, belongs to technical field of petroleum extraction.
Background technology
After excessive round steam soak, oil-gas ratio is begun to decline, it is necessary to be transferred to the steam drive stage just heavy crude reservoir
Thick oil recovery ratio can further be improved.But with the increase and the extension of steam injection time of steam injection amount, ratio occurs in steam-drive process
The more serious steam overlap of steam soak process and channeling phenomenon, i.e. steam one direction are advanced by leaps and bounds, and oil reservoir heating is uneven, and then leads
Cause steam swept volume is small, the thermal efficiency is low, economic benefit declines.Overall swept volume and heavy crude reservoir are driven in order to improve steam most
Whole recovery ratio, it is necessary to take effective measure to prevent channeling.Research has shown that, in steam-drive process, injects high warm bathing with steam
Foam agent can improve the sweep efficiency and displacement efficiency of injection steam, and restrict the key technology that this technology is applied to steam drive
Problem has two：One be foaming agent high temperature foam performance, i.e., can be foamed at a high temperature of 300 DEG C, another is foam
Stability, i.e., can the foam that formed at high temperature be stabilized.Wherein, resistant to elevated temperatures foaming agent has been developed (grandson
Build the such as peak, Guo Donghong, Xin Hao rivers " synthesis of JP series of high temperature foaming agents and performance evaluation ", oil drilling technology, 2011,33
(2), 117-119；Guo Donghong, Xin Haochuan, Cui Xiao east " improve steam drive effect high temperature foam agent research ", finely with it is special
Chemicals, 2010,18 (11), 41-44), it is often more important that needs are developed and foam can be allowed to remain stable at high temperature
High temperature foam stabilizer.Starting foam volume and half foam life period are to weigh two good and bad important parameters of foaming agent performance,
One difficulty or ease and quantity for reflecting foaming, the stability for reflecting foam, for the nature static of overall merit foaming agent
Can be, it is necessary to consider the influence of starting foam volume (maximum foam volume) and half foam life period to foaming properties.
For above-mentioned bottleneck problem and the deficiencies in the prior art, research and development are a kind of to have heat under 300 DEG C of hot conditions
It is this area urgent problem to be solved that stability is good, can keep the stable high temperature foam stabilizer of high temperature foam.
The content of the invention
Needed in view of reality, an object of the present invention is to provide a kind of foam stabiliser, steady added with the foam
Determine the foaming agent of agent has that heat endurance is good, high temperature foam can be kept stable under 300 DEG C of hot conditions.
Another object of the present invention is to provide the preparation method of foregoing foams stabilizer.
Another object of the present invention is to provide the application of foregoing foams stabilizer.
It is still another object of the present invention to provide a kind of foaming agent, and it contains foregoing foams stabilizer.
