Abstract

The invention discloses a reservoir blockage removing agent which comprises, by weight, 10-17 parts of fluoroboric acid, 5-9 parts of emulsifier, 5-7 parts of surfactant and 67-80 parts of water. The reservoir blockage removing agent has good blockage removing effect.

Description

Oil layer blocking remover
Technical field
The invention belongs to oil production field of chemicals, particularly, relate to a kind of oil layer blocking remover.
Background technology
In oilfield development process, because reservoir pressure, temperature raise, inject the impact of the factor such as not mate of water and outside fluid, cause inorganic salt, paste the blockings such as compound, biological clay, polymkeric substance, make production capacity can not get effective exploitation.Therefore, it is very important for studying the good oil layer blocking remover of a kind of plugging removal effect.
Summary of the invention
Technical problem to be solved by this invention is to provide the good oil layer blocking remover of a kind of plugging removal effect.
The present invention's adopted technical scheme that solves the problem is:
Oil layer blocking remover, comprises the component of following weight part:
