Abstract
The invention discloses an organic deblocking agent comprising the following raw materials in parts by weight: 80 parts of heavy aromatics, 10 parts of oxalate mono-n-butyl ether, 1 part of activating agent, 5 parts of demulsifying cleanup agent for fracturing and 2 parts of oil soluble penetrating agent. The raw materials are added in a reactor and uniformly agitated for 60 minutes at a temperature of 40 DEG C to obtain a finished product. The activating agent is fatty alcohol-polyoxyethylene ether. The deblocking effect and the safety properties of the deblocking agent are improved.
Description
Technical field
The present invention relates to petroleum industry chemical article technical field, especially relate to a kind of organic unblocking agent that is used for oil well.
Background technology
In the oilfield development process, because the rising of reservoir pressure, temperature, the influence of injecting factors such as being incompatible of water and outside fluid, opsonigenous substances gathering, cause obstructions such as inorganic salt, iron cpd, biological clay, polymkeric substance, make production capacity can not get effective performance.Especially in being in, the oil field of back development stage, profit is further complicated, pit shaft situation variation, above-mentioned obstruction is serious day by day.Therefore, be used for the unblocking agent widespread use of oil well, but present unblocking agent not only flash-point is lower, safety performance is relatively poor, and plugging removal effect is relatively poor.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of organic unblocking agent, improve the plugging removal effect and the safety performance of unblocking agent.
For achieving the above object, the present invention by the following technical solutions:
Unblocking agent of the present invention proportioning raw materials by weight is as follows: 80 parts of heavy aromaticss, 10 parts of oxalic acid monobutyl ethers, 1 part of promoting agent, 5 parts of pressure break breakdown of emulsion cleanup additives, 2 parts of oil soluble permeate agents; Raw material is added in the reactor, and evenly stirring got product in 60 minutes under 40 ℃ of environment of temperature; Described promoting agent adopts fatty alcohol-polyoxyethylene ether.
The invention has the beneficial effects as follows:
Unblocking agent of the present invention since the set of dispense ratio choose reasonable, its close flash point temperature reaches 55 ℃, thereby has improved the security of construction operation, has strengthened the crude oil dispersion and emulsion, unblocking agent simultaneously of the present invention strengthens sweep area, thereby improves mud oil circuit plugging removal effect.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can obtain instruction from the practice of the present invention to investigating hereinafter.
Embodiment
During concrete enforcement, prepare raw material (by weight) according to following proportioning raw materials: 80 parts of heavy aromaticss, 10 parts of oxalic acid monobutyl ethers, 1 part of promoting agent, 5 parts of pressure break breakdown of emulsion cleanup additives, 2 parts of oil soluble permeate agents; Then raw material is added in the reactor successively, evenly stirring got product in 60 minutes under 40 ℃ of environment of temperature.Wherein, described promoting agent adopts fatty alcohol-polyoxyethylene ether (AEO-3); It is Y-03 that pressure break breakdown of emulsion cleanup additive adopts specification; It is OP-10 that the oil soluble permeate agent adopts specification.Unblocking agent of the present invention since the set of dispense ratio choose reasonable, its close flash point temperature reaches 55 ℃, thereby has improved the security of construction operation, has strengthened the crude oil dispersion and emulsion, unblocking agent simultaneously of the present invention strengthens sweep area, thereby improves mud oil circuit plugging removal effect.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
