Abstract
The invention discloses an oil field sewage bactericide and a preparation method thereof, belonging to the technical field of chemical agents for oil fields and preparation thereof. The oil field sewage bactericide is prepared by mixing the following components in percentage by mass: 10-15% of nano titanium dioxide powder, 0.5-2% of crosslinking agent, 5-10% of surfactant, 5-10% of oxidizer and the balance of water. The bactericide can be deposited on pipe walls, bent angles and other parts along with a liquid flow; a main agent can be slowly diluted out, has persistent chemical action and causes no corrosion to pipelines; the comprehensive sterilizing rate of the bactericide with respect to sulfate reducing bacteria, saprophytic bacteria and iron bacteria can be still up to 90% or above 18 days after filling; and the filling period of the chemical agent is 15-25 days which is 10-15 times longer in comparison with a common chemical agent, thereby greatly relieving the operation intensity and lowering the cost.
Description
Technical field
The present invention relates to a kind of oilfield sewage bactericide and preparation method thereof, belong to chemical agent and preparing technical field for oil field.
Background technology
Each elephant is when produced-water reinjection, water injection equipment, pipeline and water injection well pit shaft are because water pollution, obstruction, corrosion etc. easily occur bacteria breed, generally by the filling bactericide, solve the harm that bacterium is caused, the bactericide of filling mostly is liquid at present, while adopting the filling of batch (-type) dosing method, due to the impact that is subject to current, the medicament timeliness is difficult to lasting, while adopting the continuous dosing mode to annotate, cost is too large and waste time and energy.Patent 201010202497.7 discloses a kind of oilfield reinjection water sterilizing agent, the raw material of following weight ratio example, consists of: fourth diamino 1-3 part, guanidine sulfate 3-5 part, polyhexamethylene guanide 1-2 part, polyolefin guanidine 1-2 part.This bactericide is to the fungi in oil field reinjection water, heterotrophic bacteria, particularly saprophytic bacteria, and sulfate reducing bacteria, iron bacteria have special efficacy, and this bactericide stable chemical performance, and sterilizing time is long-acting.But this bactericide needs filling continuously, and troublesome poeration and cost are higher; " Petroleum Engineering Construction " the 34th the 6th phase of volume in 2008 discloses one piece of " application study of electrolytic brine sterilization technology in disposing polluted water in oil " document, provided a kind of method that is directly used in the oilfield sewage sterilization by the on-the-spot generation of electrolytic brine clorox, sterilization has good continuity, but equipment is corrosive." Shanxi chemical industry " the 29th the 1st phase of volume in 2009 discloses one piece of " dissimilar bactericide is to SRB bactericidal effect research in oilfield sewage " document, respectively several bactericide such as Non-oxidized, oxidized form, nitrites have been carried out to test evaluation, point out that the non-oxidative bactericide effect is best, its sterilizing rate on average can reach 96.37%, but still exists drug effect to be difficult to lasting and the high problem of cost.
Summary of the invention
The objective of the invention is for overcome the duration of efficacy that above-mentioned existing bactericide exists short, be corrosive, the shortcoming such as cost is higher, a kind of oilfield sewage bactericide is provided.
Be to provide the preparation method of above-mentioned oilfield sewage bactericide simultaneously.
The present invention is realized by the following technical programs:
A kind of oilfield sewage bactericide is mixed according to following mass percent by nano titanium dioxide powder, crosslinking agent, surfactant and oxidant: 10～15% nano titanium dioxide powder, 0.5～2% crosslinking agent, 5～10% surfactant, 5～10% oxidant, surplus are water.
The particle diameter of described nano titanium dioxide powder is 10～50nm.
Described crosslinking agent is ethylene glycol, epoxychloropropane or 4-mercaptobenzoic acid.
Described surfactant is dodecyl benzyl dimethyl ammonium chloride or stearyl dimethyl benzyl ammonium chloride.
Described oxidant is clorox or postassium hypochlorite.
A kind of preparation method of oilfield sewage bactericide comprises the following steps: accurately get each component according to mass percent, first nano titanium dioxide powder is added to the water, then add crosslinking agent, stir 1～2 hour after being heated to 60～80 ℃; Add again surfactant and oxidant, stir evenly and get final product.
The particle diameter of described nano titanium dioxide powder is 10～50nm.
Described crosslinking agent is ethylene glycol, epoxychloropropane or 4-mercaptobenzoic acid.
Described surfactant is dodecyl benzyl dimethyl ammonium chloride or stearyl dimethyl benzyl ammonium chloride.
Described oxidant is clorox or postassium hypochlorite.
Beneficial effect of the present invention:
The present invention by the nano titanium oxide microparticle with larger specific surface, stronger adsorptivity and heat endurance as carrier, surfactant and oxidant are as host, this bactericide can be deposited on tube wall, bent angle etc. with liquid stream and locate, slowly dilute host, lasting medicine, corrosion-free to pipeline, the comprehensive sterilizing rate to sulfate reducing bacteria, saprophytic bacteria and iron bacteria after 18 days of annotating still reaches more than 90%, and the medicament filling cycle is 15～25 days, be 10～15 times of General Medicine, greatly slowed down manipulation strength and reduced cost.
