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

[0028] A kind of testing method of the static stability of heavy oil applicable to the field of heavy oil exploitation that this embodiment relates to, comprises the following steps:

[0029] (a) preparing thick oil emulsion;

[0030] (b) placed in the experimental container;

[0031] (c) put into super constant temperature water bath and leave standstill;

[0032] (d) start timing and record the volume of separated water at different times;

[0033] (e) After standing for a period of time, identify the type of the upper emulsion, and calculate the water separation rate according to the following formula according to the water separation rate at different times. The smaller the water separation rate, the better the static stability of the emulsion;

[0034] f v ( % ) = V 1 V 2 × ...

Abstract

The invention discloses a method for testing static stability of thickened oil suitable for the field of mining of the thickened oil. The method comprises the steps of: (a) preparing a thickened oil emulsion; (b) putting the emulsion into an experimental container; (c) putting the container in a super constant-temperature water bath to stand; (d) beginning to time, and recording the volumes of separated water at different moments; and (e) identifying the type of the upper emulsion after standing for a period of time, and calculating the diversion ratio according to the separated water quantity at different moments, wherein the smaller the diversion ratio is, the better the static stability of the emulsion is. The static stability 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 testing the static stability of heavy oil suitable for the field of heavy oil exploitation. Background technique [0002] Against the backdrop of strong oil demand, high oil prices and declining production of conventional heavy oil, the oil industry is shifting its focus to heavy oil production in many parts of the world. Global oil resources are about 9-13 trillion barrels (1.4-2.1 trillion cubic meters), [0003] Conventional heavy oil only accounts for 30% of it, and the rest is heavy oil, super heavy oil and bitumen. Heavy oil and tar sand resources are important energy sources in the world. The current global recoverable reserves are about 400 billion tons, which is 2.7 times that of conventional heavy oil recoverable reserves of 150 billion tons. [0004] As the availability of conventional oil is decreasing day by day, heavy oil is becoming an important energy source for mankind in the next century. After...
