| titleOfInvention | Thick oil dispersion viscosity reducer and preparation method thereof |
| abstract | The invention discloses a thick oil dispersion viscosity reducer and a preparation method thereof. The efficient thick oil dispersion viscosity reducer is prepared by mixing a synthesized polymer A and polyol ether according to 1:1 and then adjusting the PH to 6.5-7.5. At 50DEG C, under the test conditions of a thick oil well produced oil-water sample with viscosity of over 10000mPa.s, a reagent dosage of 0.3%, produced water salinity of greater than 20*104mg/L, a NJD-5S rotary viscometer, a stirrer with a rotation speed of 10r/min and the like, the thick oil dispersion viscosity reducer has a 50DEG C viscosity reduction rate higher than the 99% standard requirement, thus being a qualified product. The thick oil added with the efficient dispersion viscosity reducer can be uniformly dispersed in water in the form of small granules after solidification, the obtained mixture does not combine into a large block, no stickiness exists among the small granules, and the formed mixture is in a flow state in appearance. The thick oil added with a viscosity reducer involved in a comparative sample is in the form of a non-flow bulk after solidification. Thus, the thick oil dispersion viscosity reducer provided by the invention has the characteristic absent in other viscosity reducer, and can effectively meet the technological requirements of oil field thick oil recover. |
