Description
Technical field
The utility model relates to a kind of waste disposal plant, especially relates to a kind of disposing polluted water in oil device.
Background technology
Petroleum industry flourish, national economy has been played important pushing effect, but the gas that in oil and gas exploration and development process, produces, solid, liquid the like waste, if do not handled, then can produce greatly ecotope and pollute, wherein drilling waste water is topmost source of pollution in the exploratory development.Along with the increasing of oil, natural gas exploration and development difficulty, the increase of drilling depth, the amount of well-drilling waste water is constantly increasing, and the composition of waste water is also complicated day by day, and is also more and more difficult to the processing of waste water.Meanwhile, country is more and more high to the protection requirement of ecotope, the law of environment protection aspect, and rules are gradually improved and strengthen, thus the environmental protection pressure that petroleum drilling unit is faced grows with each passing day.But, existing oil field sewage treating equipment or processing cost are high, processing horizontal is low, the basic needs that do not satisfy production and environmental protection, therefore, feasible on the exploiting economy, technical reliable well-drilling waste water treatment facility, for petroleum drilling unit, has very urgent realistic meaning.Because the well-drilling waste water complicated component comprises drilling cuttings, oil, lubricant, scale inhibitor, sterilant etc., well-drilling waste water also contains hazardous substances such as multiple salt and heavy metal, in addition, the environmental pollutants load is high, and the colourity height is sorrel or chocolate usually; Well-drilling waste water concentration of suspension height, its content is everlasting more than the 2000mg/l, contains a certain amount of oil.Each oil-gas field of China has been carried out the research improvement work of drilling waste water since the early 1980s, has taked a series of Pollution abatement measures on management and treatment technology.The main methods of drilling waste water can reduce physics method, chemical method, physico-chemical processes, biochemical process or the like at present.Physical treatment process simple to operate, expense is low, but process range is limited, and the water quality after the processing can't reach requirement.The treatment effect of method of chemical treatment is better, but required reagent need buy, so expense is higher.Physico-chemical processes combines physics and chemically treated advantage, but is unsuitable for the processing at scene, oil field.The process range of biochemical process is limited, and some macromolecular compound can not adopt this method.Because various treatment processs respectively have relative merits, generally several different methods are used in combination at the scene, but from processing cost and effect, still can not reach the energy-conserving and environment-protective requirement.At present, the general processing mode that adopts of drilling waste water is: build sewage lagoon in the well site, be stored into a certain amount of, with pump by pipe-line transportation to water-injection plant, be recycled into disused well by pipeline again.Generally, several mouthfuls of wells just need be built a water-injection plant, transport sewage with pipeline or automobile between every mouthful of well and the water-injection plant; Perhaps build sewage lagoon in the well site, sewage is just adorned in the pond, and each sewage lagoon all stays certain outage, treats that sewage natural is evaporated to a certain degree, carries out backfill and hardened ground again and handles.These two kinds of processing modes, preceding a kind of investment cost is big, and often the hardware investment at a re-injection station just needs up to ten million yuans, and daily management and working cost are also very high, and produced-water reinjection is also very important to the destruction that underground water and environment cause.A kind of mode in back is beaten the sewage lagoon that a bite well will be built kilostere.Build sewage lagoon, building sewage lagoon rain-proof shelter and backfill hardened expense neither a decimal, every local well-digging, all unavoidable this pen investment, simultaneously, Special Circumstances occur in the well-digging process, must spend high cost unnecessary sewage is transported to the re-injection station.Even more serious is if that extreme weathers such as chance heavy rains, sewage lagoon is filled the excessive serious environmental pollution incident that will cause in back, not only can pay huge processing cost, cause great social negative impact also can for petroleum drilling department.At present the defective of the disposing polluted water in oil device that adopts has: one, owing to need to add medicament such as flocculation agent in the treating processes, increased the probability of secondary pollution.Two, technical process is longer, and medicine and pollutant reaction need the regular hour, and the processing that adds medicine itself has increased the load of device, and three kinds of factor stacks have influenced the processing efficiency that installs.Three, processing cost height, this is maximum weakness.Because the medicine that adds and the price of reverse osmosis membrane are all very high, the processing cost of sewage per ton reaches more than 150 yuan.
