Abstract
The invention discloses an oil well cleaning scale inhibitor which comprises, by weight, 7-9 parts of fluoroboric acid, 3-5 parts of fatty alcohol-polyoxyethylene ether, 10-15 parts of 2-phosphonobutane -1,2,4-tricarboxylic acid sodium salt, 0.01-0.08 part of vitamin E and 70-80 parts of water. The oil well cleaning scale inhibitor can be used for removing scales of oil wells effectively.
Description
Technical field
The invention belongs to oil production field of chemicals, particularly, relate to a kind of oil well and clean scale inhibitor.
Background technology
For improving the recovery ratio of crude oil, oil production process is divided into three phases usually, is respectively primary oil recovery, secondary oil recovery and tertiary oil recovery.And along with the enforcement of tertiary oil recovery, the problem of oil well fouling also can expose, and has a strong impact on production of normally recovering the oil thereupon.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of oil well and cleans scale inhibitor, makes oil production smooth.
The present invention's adopted technical scheme that solves the problem is:
Oil well cleans scale inhibitor, comprises the component of following weight part:
Fluoroboric acid: 7-9 weight part;
Fatty alcohol-polyoxyethylene ether: 3-5 weight part;
2-phosphonobutane-1,2,4-tricarboxylic acid four sodium: 10-15 weight part;
Vitamin-E: 0.01-0.08 weight part;
Water: 70-80 weight part.
To sum up, the invention has the beneficial effects as follows: oil well of the present invention cleans the phenomenon that scale inhibitor effectively can solve oil well fouling.
