This paper specifically analyzes be special types of wellbore effect such as high specific gravity killing fluid + composite test string, oil-water two phase + multilayer, effect caused by condensation of condensate gas.
Aiming at the problem of coking in heavy oil catalytic cracking, the 1400kt/a resid FCCU in Jinan Refinery took a series of technical measures for inhibiting coking, such as employing reasonable equipment structure, optimizing the process conditions, and strengthening the management, etc. . Although the feedstock had high specific gravity and high CCR, the unit had successfully running 573 days.
By virtue of its high specific gravity, barytes is extensively used as drilling mud in oil well industry.
On the other hand, injected labelled protein failed to comigrate with the lysosomal markers in starved as well as Triton treated rats and conspicuously remained in a region of high specific gravity in the gradient.
Within a variety, proportionately larger numbers of large starch granules are associated with tubers of high specific gravity, and more smaller granules, with low specific gravity.
Reeves Kingpin is suitable for processing into french fries due to its large tubers, high specific gravity, and acceptable fry color.
All but one of these genotypes also possessed a high specific gravity of tubers.
From the mud rheology and drilling hydraulics, the factors affecting the penetration speed by heavy mud are discussed in this paper. It is pointed Out that the use of the heavy materials with high specific gravity and an improvement on the mud purification are the ways which can be followed in increasing penetration speed at the formation interval of using the heavy mud.
Heavy crude oil has high specific gravity, viscosity and acidity. Its corrosiveness is strong and its processing is very difficult. Phenolamine demulsifier was synthesized for Xinjiang Kelamaye heavy crude oil after evaluating several kind demulsifiers. Study on the effect of composition of phenolamine demulsifier on desalting and deaciding for heavy crude oil and the technolgy route of processing high acidity heavy crude oil alone was made.

Aiming at the problem of coking in heavy oil catalytic cracking, the 1400kt/a resid FCCU in Jinan Refinery took a series of technical measures for inhibiting coking, such as employing reasonable equipment structure, optimizing the process conditions, and strengthening the management, etc.. Although the feedstock had high specific gravity and high CCR, the unit had successfully running 573 days. The inspection in turnaround showed that except the coking on feed nozzles was rather serious, the other areas only showed slight coking or no coking. The reason of coking in individual place was analyzed and preventing measures were adopted.
