Abstract
The invention relates to the technical field of fine chemical engineering and particularly relates to a composite blockage removing fluid. The composite blockage removing fluid is prepared from the following components in percentage by weight: 10-20% of citric acid, 20-30% of aminosulfonic acid, 5-10% of castor oil polyoxyethylene ether, 5-7% of potassium dichromate, 1-5% of ethyl acetate and the balance of water. The invention aims at providing a composite blockage removing fluid which is obvious in effect and simple to construct.
Description
Technical field
The present invention relates to the technical field of fine chemistry industry, specifically a kind of composite blockage relieving liquid.
Background technology
In the process of oil-field development, due to the rising of reservoir pressure, temperature, inject not mating of water and outside fluid, the impact of the factors such as the managing gathering of bacterial metabolism, cause inorganic salt, paste the blockings such as compound, biological clay, polymkeric substance, make production capacity can not get effectively playing.Especially in, the oil field of rear development stage, profit is complicated further, and pit shaft situation is poor, and above-mentioned blocking is day by day serious.Therefore, the unblocking agent for oil well should use widely, and the kind of unblocking agent is also varied, but traditional well stimulation and the adaptability of block releasing technique to this change poor, effect is undesirable.
Summary of the invention
The object of the invention is to be to provide a kind of successful, simple composite blockage relieving liquid of constructing.
The technical solution used in the present invention is, a kind of composite blockage relieving liquid, and described material forms by weight percentage: citric acid 10-20%, thionamic acid 20-30%, castor oil polyoxyethylene ether 5-10%, and heavy complex acid potassium 5-7%, ethyl acetate 1-5%, all the other are water.
Advantage of the present invention is quick corrosion, dissolves tamper, improves rate of permeation, and shorten the engineering time, effect of increasing production is obvious.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of composite blockage relieving liquid, described material forms by weight percentage: citric acid 20%, thionamic acid 20%, castor oil polyoxyethylene ether 10%, heavy complex acid potassium 5%, ethyl acetate 5%, and all the other are water.
Embodiment 2, a kind of composite blockage relieving liquid, described material forms by weight percentage: citric acid 10%, thionamic acid 30%, castor oil polyoxyethylene ether 5%, heavy complex acid potassium 7%, ethyl acetate 1%, and all the other are water.
Embodiment 3, a kind of composite blockage relieving liquid, described material forms by weight percentage: citric acid 15%, thionamic acid 25%, castor oil polyoxyethylene ether 7.5%, heavy complex acid potassium 6%, ethyl acetate 3%, and all the other are water.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
