Abstract
The invention discloses an inorganic de-blocking agent, which is prepared from the following raw materials in part by weight: 50 parts of hydrochloric acid, 20 parts of glacial acetic acid, 10 parts of slow corrosion inhibitor, 10 parts of multifunctional additive, 5 parts of discharge aiding agent, and 5 parts of iron ion stabilizing agent. The raw materials are added into a reactor and stirred uniformly for 30 minutes so as to obtain the de-blocking agent. The high-temperature-resistance performance and the effect of de-blocking by acidification in deep parts of oil and gas wells of the de-blocking agent are improved.
Description
Technical field
The present invention relates to petroleum industry chemical article technical field, especially relate to a kind of 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 resistance to elevated temperatures is relatively poor, the deep plugging removal effect is bad.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of inorganic unblocking agent, improve unblocking agent resistance to elevated temperatures and the acidification to dispel block effect of oil gas well depth portion.
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: 50 parts of hydrochloric acid, 20 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; 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 resistance to elevated temperatures of unblocking agent, strengthen the solvency power of silicate, thereby help strengthening the effect of deep de-plugging.
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): 50 parts of hydrochloric acid, 20 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 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 is the product that adopts sky, Tianjin sincere chemical industry company limited, multifunction additive is the product that adopts sky, Tianjin sincere chemical industry company limited, and cleanup additive adopts the product of sky, Tianjin sincere chemical industry company limited, and Fe stabilizer adopts the product of sky, Tianjin sincere chemical industry company limited.Unblocking agent of the present invention can greatly improve the resistance to elevated temperatures of unblocking agent, strengthen the solvency power of silicate, thereby help strengthening the deep de-plugging the last explanation of effect be, 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.
