Problems solved by technology

However, the currently used emulsifying viscosity reducers only have a single temperature-resistant or mineral-salt-resistant performance, that is, the research and development of temperature-resistant and mineral-salt-resistant emulsified viscosity reducers is still rare.

Embodiment

[0025] A method for measuring the relationship between yield value and temperature of a heavy oil involved in this embodiment includes the following steps:

[0026] (a) extracting heavy oil samples for later use;

[0027] (b) weigh a certain amount of heavy oil sample and place it in the reaction vessel;

[0028] (c) heating in a water bath, and in the process of heating and dissolving, at regular intervals, the heavy oil is tested by a thermometer and a rheometer, and the data is recorded;

[0029] (d) Through the test data, a graph is drawn to analyze the relationship between the yield value of the heavy oil and the temperature.

[0030] In the step (b), the weight of the heavy oil sample taken is 10 grams.

[0031] In the step (b), the experimental container is a distillation flask.

[0032] In described step (c), rheometer is Haake Rheostress RS600 rheometer.

[0033] In the step (c), the interval time is 30 minutes.

[0034] The data measured by the above method are ...

Abstract

The invention discloses a method for determining relation between a yield value and temperature of thickened oil. The method comprises the steps of: (a) extracting a thickened oil sample for later use; (b) weighing certain amount of thickened oil sample inside a reaction container; (c) heating in a water bath, testing the thickened oil through a thermometer and a rheometer at an interval of certain time in heating and dissolving processes, and recording data; and (d) drawing a curve graph through test data, so as to analyze the relation between the yield value and the temperature of the thickened oil. The relation between the yield value and the temperature of the thickened oil can be rapidly tested by the method; and the method is high in test accuracy and low in test cost, and data support is provided for mining of the thickened oil.

Description

technical field [0001] The invention relates to a method for measuring the relationship between yield value and temperature of heavy oil. Background technique [0002] With the decreasing availability of conventional oil, heavy oil is becoming an important energy source for mankind in the next century. After more than 20 years of hard work, the global heavy oil industry has developed faster than conventional oil. The annual output of heavy oil and tar sands has risen from 20 million tons to nearly 100 million tons, and its importance has attracted increasing attention. The difficulties in the exploitation of heavy oil reservoirs are mainly manifested in two aspects: on the one hand, the viscosity of heavy oil is high, and the seepage resistance of heavy oil in the oil layer is large, so that the heavy oil cannot flow from the reservoir to the bottom of the well; on the other hand, even in the oil reservoir Under certain conditions, the heavy oil can flow into the bottom of ...
