The invention discloses a method for preparing a thick oil emulsifying viscosity reducer solution. The method comprises the steps of: (a) preparing a thick oil emulsifying viscosity reducer sample for later use; (b) exactly weighing 0.001g of thick oil emulsifying viscosity reducer; (c) dissolving the thick oil emulsifying viscosity reducer in distilled water to obtain a mixture and quantitatively transferring the mixture into an experiment container; and (d) diluting the mixture with water, thereby obtaining the target solution. By virtue of the method, the thick oil emulsifying viscosity reducer solution can be safely and rapidly prepared and all the performance parameters of the prepared solution are excellent, therefore a premise is provided for the use of the thick oil emulsifying viscosity reducer.
Description
technical field [0001] The invention relates to a method for preparing a thick oil emulsified viscosity reducer solution. Background technique [0002] The discovered heavy oil resources in my country are also very rich. More than 20 heavy oil fields have been discovered, distributed in Liaohe, Shengli, Xinjiang, Dagang, Jilin and other areas. It is estimated that China's heavy oil bitumen resources can reach more than 300×108t. The resources of heavy oil (heavy oil with high viscosity, viscosity above 0.1Pa·s) are widely distributed in China, and the geological reserves reach 164×108t, among which heavy oil on land accounts for more than 20% of the total petroleum resources. The prominent feature of heavy oil is the high content of asphaltenes and colloids. The production of heavy oil with high content of colloid and asphaltenes accounts for about 7% of the total production of heavy oil. [0003] As the availability of conventional oil is decreasing day by day, heavy oil ...
