Description
Technical field
The invention belongs to waste liquid of drilling environment-friendly disposal system fields more particularly to a kind of drilling cuttings for drilling well site with brill
Biological treatment system, suitable for drilling cuttings with administering after brill and brill.
Background technique
With the fast development of China Petroleum, problem of environmental pollution caused by drillng operation is also increasingly severe.
Due to various factors such as cost, the most of oil field in China mostly selects landfill disposal to the processing mode of drilling fluid, i.e.,
It first digs a drilling fluid pot in place before drilling well, is then evaporated and dries by natural conditions, finally at it
Surface landfill surface soil is covered.This processing method rainwater it is few place obtain effect it is preferable, but rainwater it is more or
Water source place more abundant, rejected well drilling liquid are easy to produce leakage, cause seriously to neighbouring soil, surface water and underground water
Pollution.Rejected well drilling liquid is mainly composed by the waste liquid as caused by drilling fluid, drilling cuttings and other operations.It is estimated that water
Base drilling cuttings proportion is 64.7%.
In recent years, many countries proposed the target of drilling wastes " zero-emission ", from drilling wastes Sources decreasing, process
It controls end-o f-pipe -control to be all strict with stage by stage, the environmental pollution of drilling wastes to be minimized water
It is flat, thus the systematization, standardization and the standardization that push drilling wastes to handle.Foreign countries are in water-based drilling offal treatment side
Dehydration technology, predominantly chemically enhanced solid-liquid separation technology are greatly developed in face, separate at effluent reuse or roping to concentration
Station processing is managed, roping processing of slagging tap is separated.The main method of domestic each oilfield treatments drilling wastes is completed in drilling well at present
Unify to administer afterwards, first by drilling wastewater treatment or recycling, curing process is uniformly then carried out to drilling well solid waste, finally
Ground landfill second ploughing or roping are left concentratedly to specified slag tip.Brill is transported to the drilling well solid waste within the scope of environmental sensitive area
Jing Gufeichulichang centralized processing realizes the harmless treatment and money of drilling well solid waste by solidification and comprehensive utilization device in field
Sourceization utilizes.All these processing techniques are end-of-pipe control technology.After new environmental law is implemented within 2015, each oil field is to reduce to bore
The environmental hazard of solid liquid waste during well, numerous and confused test do not land technology using drilling cuttings, do not land processing with brill and have become
The trend of drilling well environmental protection development.The technology be broadly divided into collection transfer, be separated by solid-liquid separation, liquid phase processing or utilization, solid phase processing or
Solid phase such as temporarily stores at 4 units.Since most oil fields lack the technical specification or regulation guidance of solid phase final disposal method, mesh
The solid phase in preceding many oil fields directly temporarily stores, and mostly uses and cheats interim storage with antiseepage film near well site, shifts collection after complete well
In further curing process.But for a large amount of inorganic or organic salts are added in drilling fluid, pitch, sulfonated bodies, contain oil lubricant
The drilling cuttings of equal auxiliary agents, is not suitable for directly solidifying, it is necessary to it is curable first to carry out the operations rears such as heavy metal stabilization, organic matter degradation.
For 10% or less drilling cuttings of oil-containing, some places use biological degradation method, decompose oily phase by the effect of microorganism, make organic matter
BOD and COD is reduced.Common to have aerobe method, anaerobic biological process, enzyme biologic treating technique and Fermentation Engineering etc., advantage is
It is mutually more thorough to decompose oil for less investment, the disadvantage is that long processing period is suitable for concentrating station processing there are microbiological hazards etc..
Some oil field clear stipulaties cannot use curing method, cannot fill.How the cleaning treatment of drilling cuttings and utilization are become especially
It is crucial.
