Background technology
Most important pollution sources during oilfield waste mud is produced as drilling well are a kind of containing clay, weighting material, variousization
Learn inorganic agent, sewage, sump oil and drilling cuttings multiphase stable state colloidal suspended substance, environmentally hazardous main component be hydro carbons, salt,
Impurity in various polymer, lignosulfonates, certain metal ions (mercury, copper, arsenic, chromium, zinc and lead) and barite.It will
Pollution is generated to soil, earth's surface and underground water, harm directly or indirectly is generated to animals and plants and human health.
According to investigations, 1 side's waste mud can pollute 40~70 necromancer earth, be unable to normal growth within 5~7 years；1 side's mud cocoa makes
200~400 side's river waters lose water plant and fish.If general arable land per acre is polluted by 50Kg mineral oil, it can cause 20~
30% crops are dead, and Surviving fraction is not set seeds grain substantially；When pollutant reaches 75Kg, common crops can not be deposited substantially
Living, this quantity is only equivalent to the mineral oil containing 50~60mg/L in water, however the waste water that often discharges of situ of drilling well and useless
Gurry mineral oil in fluid content greatly exceeds 100mg/L, and harm is well imagined.It is filled out if after drilling wastes are naturally dry and hard
It buries, then meet water to return slurry again, directly affects dirty mud sump part earthing and restore abandoned land to cultivation, cause potential long-term hazards.
