Description

The ground sludge classification processing system that oil exploitation generates

Technical field

The utility model belongs to the ground sludge process field of oil exploitation generation, the danger that ground sludge is promulgated in Chinese Ministry of Environmental Protection HW08 is classified as in dangerous waste register, so the present invention is also subordinated in field of environment protection, hazardous waste disposal.More particularly to stone The ground sludge classification processing system that oil exploitation generates.

Background technology

With the rapid development of petroleum industry, caused environmental problem is more and more prominent in oil gas field production process.Its In, oily sludge is that one of important pollution generated in oil play development process and restriction oilfield environment continuous quality carry High problem；Oily sludge is mainly derived from the tank generated during the landing oily sludge of oil extraction generation, oil field gathering and transportation The oily sludge that bottom oily sludge and sewage from oil refinery treatment plant generate.Wherein, landing oily sludge is oil recovery production process In, oil that oil-producing region ground is scattered in into gathering line can not be made full use of and recycle or from stone by having part oil The oil leaked out in oil pipeline mixes oily sludge with ground gravel, silt, weeds etc.；During petroleum transportation, Also oil is had to be leaked on the ground or also result in oil leakage due to occurring accident in transportational process；In addition to this, oil fills Put and oil well disassembly process in occur oil dripping, run oil, bleed etc. also can reveal part oil on the ground, oil-well blowing or open flow Part oil can not recycle the ground sludge that can also fall on and on the ground, be formed with crude oil smell afterwards.

At present, it is main following several for the treatment process of ground sludge：（1）Chemical treatment method：It is divided into microorganism The microorganism of domestication is added in the processing of ecological method and microbial method, wherein microbial ecological method；（2）Thermal decomposition process Method：It is divided into two kinds of low-temperature treatment and high-temperature process, the decomposition temperature of high-temperature process is in 1400 DEG C, the decomposition temperature of low-temperature treatment 800℃；（3）Washup logos：Oil and solid-state sundries is allowed to peel away using medicament, physical method is recycled to be separated, and then Realize oily object recycling；（4）Solid-state facture：Blocky sundries is formed by ground sludge using chemical agent, is landed with this to be promoted The controllability of greasy filth.Wherein, sundries and the perpendicular tower of the separation of oil are mainly realized using heating in tower in existing washup logos Formula or rotating cage washing etc..

There is such Railway Projects in many processing methods of greasy filth：One is the problem of technology and economy comparison, such as Fruit can reach standard requirement, but cost is very high, present oil-sludge treatment price has reached 1500 using complicated processing method Yuan/ton.The second is the problem for the treatment of capacity, fine processing method cannot meet a large amount of oil-sludge treatments, and at present, each elephant needs The greasy filth amount of processing is very big, the oil field for producing ten million ton per year for one, can generate 100,000 tons or more of greasy filth every year, also for many years Greasy filth of accumulation etc., so the process route that demand can be handled largely.The third is for thick oil sludge processing, viscosity of thickened oil is big, Because density and water are close to 0.96 ton/cubic metre, after solid matter is adhered to, it is difficult to detach.

The processing intent of ground sludge is broadly divided into two：（1）National environmental protection department is by intra-field oil-containing Solid-state castoff is classified as in the list of hazardous waste, according to relevant law, regulation, needs to produce oil field in routine duties What is gone out is suitably handled containing solid-state castoff, and not only environmentally friendly but also harmless processing mode is handled for selection, eliminates landing The harm that greasy filth is brought promotes environmental benefit；（2）In ground sludge, containing substantial portion of recyclable crude oil, to ground sludge It carries out environmental protection and effective processing mode can play the role of resource reutilization, give oil field good economic benefit.Thus As it can be seen that the ground sludge processing unit of exploitation design strong applicability is particularly important.
