Liaohe Oilfield Super Heavy Oil Doped Active Water Of Crude Oil Drop Of Viscosity,

In view of the present Liaohe River oil field ultra thick oil falls sticks needing the highly energy consumption, carried on the ultra thick oil to mix the activated water emulsification thinner research. The best characteristic parameter of emulsifies including the determination of the ultra thick oil, the goal active ingredient host medicinal preparation determination synthesis, optimal appraisal technology and to following emulsion breaking influence factor research.The research key is: (1) the suitable chemistry with highly effective surface active agent formula in the Liaohe River oil field special oil Du 84 ultra thick oil has to fall sticks effectively; (2) take does haven't the bad influence to the breaking dehydration (namely to blend with emulsion breaker) as the inspection target, optimal most ideal formula for optimized formula.Reflects this, discussed the ultra thick oil emulsification to fall sticks the mechanism firstly, through determined the ultra thick oil to emulsify the best characteristic parameter HLB value and the reference molecular structure characteristic, determined and synthesized the goal active ingredient host medicinal preparation, and screened the main medicinal preparation formula using the PIT value. Chooses four kind of different surface active agents carries on appraise according to the different proportion and the host medicinal preparation duplicate matches and performs, the optimal host medicinal preparation and the auxiliary medicinal preparation, the best formula and the best allocated proportion, then determined ultra thick perquisite base thinner LZC-C-02. Has studied the perquisite emulsion stable factor, has appraised the thinner density, the salt content in the water, the temperature, the stirs speed and time, the vibration intensity and the mix time and so on. Uses the electricity mirror and the biological microscope analysis to the perquisite emulsion, the particle size meter, the primary factor to the perquisite emulsion performance. At the same time has analyzed the emulsion breaking basic principle and has carried on the emulsion breaking dehydration experiment, inspected the emulsion breaker increment, the emulsion breaking temperature, stirs factor and speed to the emulsion breaking dehydration experiment influence.The result indicated that ultra thick perquisite base thinner LZC-C-02 in the increment is 250ppm; In the room condition drops sticking rate to as high as 99.99%, and has the good emulsion breaking performance. Does not add the emulsion breaker under the condition, subsides 1h to be possible naturally to leave mixes the complete activated water under 85℃, 16h may escape favorable balance to water 50-80% of trade thick oil, 72h ultra thick oil itself contains water may fall to 4.4%.
