用asphaltene造句子，“asphaltene”造句

Others: crude oil asphaltene content of less than 1% in general.

At high speed, asphaltene plugging is more serious with increase of flow rate. The damage degree of asphaltene plugging is higher in low permeability core than in high one.

It was found that the content and structure of asphaltene, wax and natural carboxylic acid play important roles in emulsification process.

The distribution and transfer character of iron in Liaohe vacuum residue were studied by absorption-separation, acidic solution extraction and mild chemical oxidative degradation of asphaltene.

The asphaltene deposition is the result mainly of asphaltene particles flocculation and precipitation in petroleum when the thermodynamic conditions changed.

With three phase algorithm which takes asphaltene precipitation into account, the technique can model asphaltene precipitation quantitatively.

However, gas injection for enhancing oil recovery may cause asphaltene deposit, which seriously influences production.

The precipitation mechanisms of the glial, wax and asphaltene and impact factors have been definited through a large number of experimental studies.

The effect of coconut amine on the viscosity and stability of residue asphaltene system was studied and the change in viscosity and colloid stability with coconut amine content was discussed briefly.

The second is about wettability measurement of quartz sands due to adsorption of asphaltene and resin.

Now the high concentration of asphaltene and other impurities on the transport and processing of crude oil caused difficulties.

Results indicate that asphaltene exists as soft and plastic sphericities. Asphaltene stability mainly depends on the size of asphaltene without existence of stabilizers.

The effect of stabilizers on viscosity behavior of petroleum asphaltene solutions was studied with a capillary tube viscosimeter.

To under - stand better the adsorption progress of petroleum asphaltene must see the whole adsorption behavior of asphaltene.

Aimed at the characteristic of Liaohe super heavy crude oil such as high content of heavy metal, carbon residue, gum and asphaltene, the demetallization agent for delayed coking unit was developed.

After hydrothermal catalytic pyrolysis reaction of heavy oil, the stability of asphaltene became worse.

In this paper, we review the progress in the investigation of asphaltene AD - sorption from the aspects of adsorption mechanism, theoretical model and study methods.
