石油工程英文论文文献

油田污水处理做的文献本来就少，英文版的更少。在就是你的SPE是指固体离子腐蚀还是国际石油工程师协会？我这有一篇，只是篇简单的范文，仅供参考。Water injection is an Chinese oilfield development important exploitation mode, is to supplement the formation energy, to keep the reservoir energy balance, maintain the effective method for oilfield long-term high yield, stable yield. The injected water source is the main reservoir water and ground water,shallow layer underground water and production of crude oil produced. In order to save fresh water resources on the earth, the current is injected into the reservoir water mostly from disengaging from the exploitation of crude oilin the water, used to call the sewage. Generally have accounted for about80% of the total national water injection. Untreated sewage containingsuspended solids, a lot of emulsified oil, bacteria and other harmful substances. Water is injected into the reservoir as drinking water to enter the human body, if they drink untreated water, the human body will be hurt, occur in various diseases; the same oil injection of untreated sewage, oil will damage is mainly reflected reservoir blockage in a breeding bacteria,mechanical impurities and iron deposits, causing the injection pressure increases, water volume decreased, affecting the efficiency of water floodingfor crude oil. Therefore, we must on into the reservoir water purification the sewage is produced from the reservoir, so the main purpose ofoilfield sewage treatment is the removal of oil and suspended solids speaking, can be divided into two stages, the first section is thedegreasing stage, the stage is demulsification and flocculation by oil, waterdensity difference and chemicals will be oil and water separation; secondsection is the filtering stage, this stage is the use of filter adsorption,interception, surface sewage suspended solids, oil and other impuritiesadsorbed on the filter or not make it through the filter layer. In addition to the oil phase to the corresponding treatment methods according to the properties of crude oil in oil containing sewage density, freezing point and the home and abroad, in addition to technical method of oil phase mainly are: gravity oil separation technology, pressure settlement oil removal technology,air flotation oil removal technology, hydrocyclone oil removal gravity type oil separation technology is on the relative density of oil-water differential to achieve the purpose of removing oil. Oily water into the oil separation, large oil drops freely floating under the action of buoyancy,emulsified oil by demulsifier (coagulant) effect, by the small oil drops into a big oil drops. In the residence time, the vast majority of crude oil floats to upper oil separation are removed. Its characteristic is the large volume of sewage, oil separation, stay for a long time, even if there are sudden changes in waterflow and water quality, also do not affect the water quality. It covers an area of large, poor ability to remove emulsified oil removal technology is in addition to the settlement of filling oilequipment in the oil droplet coalescence material, when the oily wastewaterafter coalescence material layer, small oil drops into larger oil droplets,accelerate oil rising speed so as to shorten the hydraulic retention time,reduce the volume of equipment. Its characteristic is the equipment adoptscoalescence inclined plate technology, greatly improving the efficiency of oil removal. But the water content, water quality change ability than oil flotation oil removal technology is a large number of fine bubbles in oily sewage water, the particle diameter of to 25 microns suspended oil beadand solid particles adhere to the bubbles, floating to the surface, so as to achieve the removal of sewage sludge oil and suspended solid particles of theobjective. The flotation, which can greatly improve the suspended oil dropletsand solid particles floating velocity, shorten the treatment time. Its characteristic is the large capacity, high efficiency, suitable for heavy oil wastewater and oily wastewater containing emulsified oil oil removal technology is the use of the density difference between oil and water, the fluid rotates at a high speed, the centrifugal forceby the ranging function and realize oil-water separation. Its characteristic is the equipment has the advantages of small volume, high separation the relative density of crude oil is greater than of the oily water poor adaptability. Filtering filtering stage and used according to the requirements of water after filtering is divided into coarse filtration, fine filtration and fine filtration. According to the recommended standards for water quality, solidsuspended matter content is 1 ~ 5 mg / L, particle diameter of 2 to 5 core technology is the selection and regeneration of filter media. In oilfield sewage treatment, the filter is mainly used at home and abroad are: quartz sand, anthracite, ceramsite, walnut shell, fiber ball, ceramic membrane and organic membrane. Regeneration method of filter of the main hot waterbackwashing, air reverse blowing.
