Abstract
The invention discloses a high-efficiency inorganic blockage relieving agent, which is prepared with the following raw materials in parts by weight: 40 parts of fluoboric acid, 25 parts of glacial acetic acid, 10 parts of retarded corrosion inhibitor, 10 parts of multifunctional additive, 5 parts of cleanup additive, 5 parts of iron ion stabilizer, and 15 parts of anti-swelling agent; and the high-efficiency inorganic blockage relieving agent is prepared only by adding all raw materials in an agitated reactor to evenly agitate for 30 minutes. The high-efficiency inorganic blockage relieving agent can improve the dissolving capacity on silicate and carbonate, boost the blockage relieving effect, and protect the strata.
Description
Technical field
The present invention relates to petroleum industry chemical article technical field, especially relate to a kind of efficient inorganic 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, and the kind of unblocking agent is also varied, but present unblocking agent is relatively poor to the dissolving power of silicate, carbonate, does not have protection also relatively poor the stratum.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of efficient inorganic unblocking agent, improve the dissolving power to silicate, carbonate of unblocking agent, improve plugging removal effect and have the effect of protecting the stratum.
For achieving the above object, the present invention by the following technical solutions:
Its proportioning raw materials is as follows by weight: 40 parts of fluoroboric acid, 25 parts in Glacial acetic acid, 10 parts of slow inhibiter, 10 parts of multifunction additives, 5 parts of cleanup additives, 5 parts of Fe stabilizeies, 15 parts of expansion-resisting agents; Above-mentioned raw materials added in the reactor evenly to stir successively got final product in 30 minutes.
The invention has the beneficial effects as follows:
Compared with prior art; raw material of the present invention and proportioning thereof are chosen rationally; as oil gas well depth portion acidification blocking remover; can greatly improve the dissolving power of unblocking agent to silicate, carbonate; good ground mud skeleton structure more effectively; prevent that it is destroyed, thereby improve plugging removal effect and have the effect of protecting the stratum.
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): 40 parts of fluoroboric acid, 25 parts in Glacial acetic acid, 10 parts of slow inhibiter, 10 parts of multifunction additives, 5 parts of cleanup additives, 5 parts of Fe stabilizeies, 15 parts of expansion-resisting agents according to following proportioning raw materials; Above-mentioned raw materials added in the reactor evenly to stir successively got product in 30 minutes.Wherein, slow inhibiter adopts the product of sky, Tianjin sincere chemical industry company limited, multifunction additive is the product that adopts sky, Tianjin sincere chemical industry company limited, cleanup additive adopts the product of sky, Tianjin sincere chemical industry company limited, Fe stabilizer adopts the product of sky, Tianjin sincere chemical industry company limited, and expansion-resisting agent adopts yellow soda ash.The present invention can greatly improve the dissolving power of unblocking agent to silicate, carbonate, and more effectively good ground mud skeleton structure prevents that it is destroyed, thereby improves plugging removal effect and have the effect of protecting the stratum.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.
