Description
The present invention relates to a kind of high efficiency compound oil sand adhesive that is used for oil-field thick-oil Development and Production control formation sand production.
Countries in the world viscous crude resource is quite abundant, and China occupies sizable reserves.Accelerating the heavy oil development paces, is the main path that improves crude production rate.Yet,, bring many difficulties to viscous oil recovery because viscous crude itself has the viscosity height, density is big, mobile poor.Especially geologic framework is the area of major ingredient with the sandstone, the characteristics that formation cementation is loose, and constantly washing away down of resident fluid, the cementing matter between sand grains is destroyed, and formation consolidation intensity is reduced, and usually occurs that sand collapses, the fuel-displaced hole of sand plug.What is more, because the viscous crude prop-carrying capacity is very strong, the sand holddown usually takes place when producing and is forced to stop production in oil recovery, causes workover treatment quite frequent, obviously increases the oil recovery production cost, and it seriously influences crude production.The following two kinds of methods of domestic at present, external general employing are overcome.A kind of is to adopt the mechanical sand control method, and it adopts metal wire wrapped screen gravpack technology sand control in the pipe.Be that the wrapping wire steel mesh is following to the shaft bottom, prevent that reservoir sand from flowing to pit shaft and causing holddown or be full of pit shaft.The usefulness metal web sand control that has, the usefulness wrapping wire sand anchor sand control that also has.Though they are one of present sand control efficient ways, its limitation is arranged also.One, behind the wire wrapped screen gravpack technology sand control, because the hole structure complexity, thereby make troubles for workover treatment from now on.Its two, to the fine silt reservoir, owing to be subjected to the restriction of wire wrapped screen wavelength width of a slit, the poor effect of its anti-fine silt.Its three, wire wrapped screen gravel filling sand prevention operating cost height.In addition, as metal web sand control, wrapping wire sand anchor sand control, these ways are difficult to big area and promote the use of the same shortcoming that resembles the wire wrapped screen gravpack technology sand control that exists of control formation sand production in the production.Another kind is to use the chemical process sand control.Make it and oil-sand generation chemical reaction, the oil-sand gluing in the stratum, and is not influenced the normal oil recovery production of heavy oil wells.Just at present external as: the BG-1 high temperature sand-fixing agent that high temperature sand-fixing agent produced in USA and China produce, though in certain hour, can play solid sand effect, but validity period is shorter, again because synthesis material is very difficult with tetramethoxy-silicane production, cause sand-fixing agent to cost an arm and a leg, influence promoting the use of of it.In addition, just produce tetramethoxy-silicane and exist following weak point: one, complex process, equipment are many, expensive big, day output is few, as producing 20 kilograms tetramethoxy-silicane every day, needs one one cubic metre and is with electronic stirring enamel reaction still or stainless steel cauldron, a distillation tower, a large-scale refrigerator, and also need bigger plant area, investment is expensive.Its two, synthetic tetramethoxy-silicane need be used methyl alcohol, silicon tetrachloride, they all are poisonous and extremely strong Chemicals of corrodibility, heat releases a large amount of during reaction cause bumping easily, produce very dangerously, operator suck methanol steam has anesthetic action to human body, can injure optic nerve especially.Mistake is drunk methyl alcohol (1g/kg) can make visual loss, even dead.Skin contact makes chapped skin, inflammation.Methyl alcohol leakage volatilization is very fast, and maximum permissible concentration is 50mg/m in the production plant air
3Silicon tetrachloride has stronger toxicity, and it has strong impulse to human body, will emit the macro-corrosion spirit of salt during hydrolysis.Produced the high temperature sand-fixing agent in the past, key is synthetic tetramethoxy-silicane.Its working condition: harsh cold condition and tediously long Production Flow Chart, just produce tetramethoxy-silicane and will account for and produce more than 90 percent of high temperature sand-fixing agent time.
Task of the present invention is to provide a kind of high efficiency compound oil sand adhesive, and it not only is fit to formation temperature and is higher than more than 200 ℃, also can adapt to formation temperature and be lower than below 200 ℃, and it is obvious to play solid sand action effect.This high efficiency compound oil sand adhesive, glued speed is fast, intensity is high, and production unit is few, and technical process is short, easy, less investment, instant effect, and selected starting material are industrial goods, do not contain deleterious hazardous substance and deleterious industrial chemicals, production safety.In composite production process, do not discharge obnoxious flavour and waste liquid, do not have three wastes problem, do not have low temperature and pyritous reaction process in the commercial process, all carry out at normal temperatures, so, do not need other protection against corrosion enamel still yet.Because it is low that this high efficiency compound oil sand adhesive has a production cost, less investment, instant effect, site construction technology is easy, and the cycle is short, Gu sand is effective, having very much general big area promotional value, is the novel sand-fixing agent of a kind of viscous oil recovery, for a new road has been opened up in viscous oil recovery production.
