Abstract
The invention discloses a double quaternary ammonium salt type gas field reinjection water bactericide and a bactericide composition comprising the bactericide. Compared with a traditional bactericide 1227, the double quaternary ammonium salt provided by the invention has higher positive charge density, and the capacity of absorbing negatively charged bacterial cell surfaces is improved. Therefore, the bactericide provided by the invention has relatively high antibacterial activity. Also, the bactericide has the advantages of long effect duration and low foam. The double-long-chain quaternary ammonium salt has one hydrophilic group and two hydrophobic groups, such that higher capacity for reducing surface tension is provided, and water solubility can be improved. Under a condition of relatively high water hardness, good solubility and stability are shown. With the gas field reinjection water bactericide composition, a bacteria test is carried out according to an extinction dilution method represented by SY/T0532-93, and bactericidal experiments are carried out aiming at sulfate-reducing bacteria (SRB), iron bacteria (FB) and saprophytes (TGB). As a result, an effective bactericidal concentration is 20-30ppm, and a bactericidal rate reaches 99.9% and higher, such that reinjection requirements are satisfied.
Description
Technical field
The present invention relates to a kind of gas field reinjection water sterilizing agent and composition thereof, specifically belong to gas field re-injection water treatment field.
Background technology
Gas field wastewater derives from the gas extraction process, is to discharge together the outer waste water of well with natural gas.Because the saliferous (sodium chloride is main) of gas field recovered water is measured up to 20000-100000mg/L, directly discharging can cause environmental pollution and the salinization of soil, and after therefore processing, reinjection into reservoir is main outlet.
The key issue of re-injection is produced water treatment to be reached the water quality requirement (SY/T5329-94) of re-injection water.Bacterial content in gas field re-injection water is generally higher, and particularly sulfate reducing bacteria (SRB), iron bacteria (TGB), saprophytic bacteria (FB) exceed standard seriously, and in most re-injection water, bacterial content is up to 10
4～10
8Individual/mL.The amount reproduction of bacterium will form microbiologic(al) corrosion to equipment, waterflood-transmission line and other metal materials, and then infringement blocking pipe and water injection well, cause water injection well pressure to increase, water injecting consumption rises, what have even causes disused well, seriously restricts the sustainable development of gas field development.Therefore, take to add in re-injection water the mode of bactericide to carry out sterilization processing, require SRB bacterium number less than or equal to 25/mL to permeability less than the low permeability reservoir of 0.1 μ m, TGB, FB bacterium number are less than or equal to n * 10
2Individual/mL (1≤n＜10).
Gas field re-injection water belongs to high rigidity, high saliferous, high sulfur-bearing type, there is obvious difference with oil field water quality, the life condition of bacterium has determined that bacterial content and kind distribute, especially high sulfur-bearing water quality causes the quantity of sulfate reducing bacteria (SRB) to exceed dozens or even hundreds of times than oil field reinjection water, and the water-soluble and compatibility of high hardness water confrontation medicament is had relatively high expectations.Therefore adopt conventional oilfield reinjection water sterilizing agent to carry out sterilization processing and be difficult to the expection requirement, need special exploitation to be applicable to the bacteriocide formula of gas field re-injection water water quality.
