Description
Technical field
The present invention relates to oil gas field waste water-treatment technology field, specifically, relate to integrated oil gas field wastewater processing system.
Background technology
Along with the proposition of the development of economic society, the particularly Scientific Outlook on Development, Social Ecology harmony is had higher requirement.In oil gas field waste water treatment procedure, if the unreasonable process re-injection of oil gas field sewage and discharge will make oil gas field ground installation be not normally functioning；On the other hand will also result in environment, be extremely unfavorable for safety in production and the environmental conservation of oil gas field, the most how processing water of oil-gas field pollution is the key subjects that those skilled in the art pay close attention to all the time.Briefly, oil gas field waste water harnessing technique mainly has re-injection, resource reuse and processes standard discharge three kinds.The final disposal method of oil gas field waste water is still based on reinjection into reservoir at present.But the raising of environment degree is paid attention in the whole world at present, and freshwater resources are more and more shorter, following developing direction is not outer row, does not wastes, resource reuse as far as possible.
Specifically, the oil gas field waste water of existing routine is mainly made up of gas gathering station separation sewage, purification plant's production waste and residual acid waste liquid three parts.Gas gathering station major function is to collect source of the gas, carries out purified treatment, compression transmission.The medicaments such as the natural gas of the different pressures heterogeneity of each gas well is carried out collecting by gas gathering station, concora crush, then concentrates and be transported to purification plant and process, and carries out preliminary desulfurization dewatering during collecting and process, defoamer to be added.Water of oil-gas field in major part unstripped gas divides discharge in gas gathering station, forms gas gathering station separation sewage.Owing to these water of oil-gas fields have same subterranean strata and natural gas Long Term Contact, so it is in addition to containing petroleum substance, the miscellaneous materials such as solubility salt, float, harmful gas, Organic substance are also dissolved into, and it is also possible to be added various additives artificially in gas recovery, so water of oil-gas field typically exhibits following four feature: 1. petroleum substance content is high, up to 100 ~ 500
Mg/L, petroleum substance exists for main with suspended state, and part is emulsifying state, and oil emulsion distribution is stably not readily separated；2. content of organics is higher, and western sichuan region oil gas field waste water COD, substantially between 800 ~ 3000 mg/L, there may be a certain amount of cyclic aromatic compounds analog derivative, stable in properties, is difficult to oxidized removal in waste water；3. SS content is high, and particle is small, and particle diameter is generally 1 ~ 100 μm, and the total SS of waste water is 300 ~ 2000 mg/L；4. salinity is high, and containing multiple salt, every liter of waste water chlorine ion concentration reaches several ten thousand even tens0000 milligrams.These features determine oil gas field waste water and can not be directly discharged in environment, it is necessary to deal carefully with.
Purification plant's production waste includes the draining of the process units such as desulfurization in Gas Purification Factory, dehydration, sulphur recovery, vent gas treatment, the maintenance waste water of the device such as desulfurization, dehydration, the sanitary sewage that office and dining room are discharged, also having laboratory waste water, sour water stripping (SWS) tower accident draining etc., Partial cleansing factory also has the water of oil-gas field that unstripped gas is brought into.The fluctuation of its waste water quality, the water yield is big and contains a large amount of hard-degraded substances, and such as the characteristic contamination such as ethylene glycol, sulfolane, MDEA, TEG, difficult for biological degradation, the treated stably reaching standard that is difficult to discharges.Its cause produced is that the unstripped gas that sulfur-bearing raw natural gas enters factory through gas collecting main terminal filters separation facility, through gravitational settling with after filtering and being separated off the impurity carried under one's arms in raw material and part free water, enter desulfurizer, with the H in methyl diethanolamine (MDEA) solvent selectivity removing natural gas2S and CO2, wet purification gas enters 2,2'-ethylenedioxybis(ethanol). (TEG) dehydration device, obtains qualified product gas by supplying outside gas transmission line after dehydration.
Residual acid waste liquid be in oil gas field acid fracturing work progress produce waste liquid, mainly include acidizing treatment residue acid solution and be acidified after return discharge opeing.With the addition of acid solution and additive during due to acidifying, waste liquid mainly has residual acid, multiple additives, residue, petroleum-type etc..The popular feature of acidizing waste fluid is that polluter is multi-point and wide-ranging, complicated component, and acidity is big, and chloride content is up to several ten thousand even tens0000, viscosity is big, and containing H2S, direct discharge can cause environmental pollution.The process means of residual acid waste liquid routine include neutralization, flocculating sedimentation, oxidation, Fe/C light electrolysis, H2O2/Fe2+Catalysis oxidation, absorption etc..Table 1 below can probably reflect the water quality index of Dormant oils gas water of giving vent to anger:
| Pollutant | Oil | COD | S2- | SS | pH | Fe | Cl- |
| Concentration range | 0.2~1310 | 20~22600 | 0.004~508 | 60~84100 | 4.5~8.5 | 0~88 | 20000+ |
Main pollutant consistence scope (unit mg/L, except pH) in table 1 water of oil-gas field
The final disposal method of oil gas field waste water is based on reinjection into reservoir at present.There is following several shortcoming in existing re-injection technique: disposable construction investment is higher；Sewage recycling cannot be realized utilize；Periphery oil field may be produced impact；Periphery section oil reservoir may be produced impact.Along with the most harsh environmental improvement requirement and the shortage of water resource, inventor thinks that resource reuse technology certainly will replace re-injection Processing tecchnics.Therefore complicated according to oil gas field waste water quality, variation water quality is relatively big, and oil gas field is in from far-off regions and relatively decentralized mostly, and inventor is to adapting to various variation water quality and being convenient to the resource reuse work processing mode of installation and transportation and system conducts in-depth research.
