Description
Technical field
The present invention relates to a kind of infrared spectrum determination method of emulsifying and viscosity-reducing agent for condensed oil.
Background technology
Along with Gong the utilization of conventional oil reduces day by day, heavy oil is becoming the next century mankind's important energy source.Through the effort of more than 20 years, global heavy oil industry had than conventional oil speed of development faster, and the annual production of viscous crude, tar sand rises to nearly hundred million tons by 2,000 ten thousand tons, and its importance receives people's concern day by day.The difficulty of heavy crude reservoir exploitation is mainly manifested in two aspects: the viscosity of viscous crude is high on the one hand, and the filtrational resistance of viscous crude in oil reservoir is large, makes viscous crude not flow into the shaft bottom from oil reservoir; Even on the other hand under reservoir condition, viscous crude can flow into the shaft bottom, but in the process of vertical lifting, impact due to viscous crude factor such as degassed and radiating and cooling in pit shaft, make the viscosity of viscous crude further increase, have a strong impact on the normal operation of the mobile and oil well production equipment of resident fluid in pit shaft.
According to the interrelated data statistics, explored heavy oil resource mainly concentrates on the states such as Venezuela, USSR (Union of Soviet Socialist Republics), the U.S. and Canada in the world at present.The Orinoco heavy oil belt of Venezuela northeast is examined geologic reserve and is reached more than 3,000 hundred million tons.Half of U.S.'s heavy oil resource is distributed in Gary Fu Niya, nearly 40,000,000,000 tons of geologic reserve, remaining half be distributed in the continent, middle part.Canadian heavy oil resource mainly is distributed in four major sedimentary mineral reserve such as Athabasca, cold air lake, dimension Pascal and this river of Alberta, nearly 1,500 hundred million tons of geologic reserve.The heavy oil resource of USSR (Union of Soviet Socialist Republics) mainly is distributed in more than 200 hundred million tons of the Ba Sainuofuyue in West Siberia basin, comprises that also there is extremely abundant viscous crude resource in other country of China.Total geologic reserve of these heavy oil resources adds up more than 6,000 hundred million tons, and in the world conventional oil verify 3,600 hundred million tons of geologic reserve, its workable reserve is only 90,000,000,000 tons.
The viscous crude stock number that China has found is also very abundant, and existing more than 20 of the viscous crude field of discovery is distributed in the areas such as the Liaohe River, triumph, Xinjiang, huge port, Jilin, more than estimating that Chinese heavy petroleum asphalt stock number can reach 300 * 108t.China's viscous crude (highly viscous oil, viscosity is more than 0.1Pas) resource distribution is very wide, and geologic reserve reaches 164 * 108t, and wherein the land viscous crude accounts for more than 20% of oil total resources.The outstanding characteristics of viscous crude are that bituminous matter, gum level are higher.Colloid, the heavy oil production that asphalt content is higher account for 7% of viscous crude total production.
Connect the area in Daqing oil field, Henan, Inner Mongol two in recent years and found important heavy crude reservoir; Also find the viscous crude resource in areas such as Jianghan Oil-field, little, the Northwest Sichuan of peace.Heavy crude reservoir geologic reserve explored and that control has surpassed national common thin oil reserves, estimates also to have from now on new growth.
In the proven reserves of CNPC, common heavy oil accounts for 74.7%, and special viscous crude accounts for 14.4%, and super viscous crude accounts for 10.9%.
Countries in the world mainly rely on traditional thermal methods to the exploitation of high viscosity heavy oil at present, i.e. steam stimulation and steam flood.The supporting technology that China's great majority adopt steam stimulation and pit shaft to mix thin oil is recovered the oil.This method not only consumes a large amount of fuel, but also consumes a large amount of thin oils, thereby has increased widely cost for oil production.Have bibliographical information can use the Emulsifying heavy crude producing, this method is that water phase surfactant mixture is annotated the down-hole, makes full-bodied viscous crude change low viscous water external emulsion extraction into.Reducing viscosity by emulsifying is high due to its viscosity break ratio, cost is low, easy operating, and at home and abroad all there is use in the oil field at present.But the emulsifying pour depressor that uses at present only possesses single heatproof or anti-rock salt performance, namely heatproof again the emulsifying pour depressor of anti-rock salt research and development also seldom.
Surfactant has in thickened oil recovery widely to be used, and at present most popular is nonionic and anionic surface active agent, as OPEO and mahogany sulfonate.But this two classes surfactant all can not be applicable to separately temperature and the high oil reservoir of salinity.There is cloud point in non-ionics, and ambient temperature is higher than cloud point, and surfactant is namely separated out from water; Anionic surface active agent can be separated out in the water of high salinity.
After emulsifying and viscosity-reducing agent for condensed oil is synthesized, need to test its infrared spectrum, thereby obtain its performance parameter, how to determine fast and accurately its infrared spectrum, seem particularly important.
