gas content

The gas content is often low near the regional faults or in the intersection part of the regional faults.

The problem is that since the increase in the gas content did not occur abruptly, there is no clearly discernible boundary layer.

the surface holes are caused by forming gas in coatings, and the deep-seated blowholes are due to excessive gas content of liquid-Al.

It was the particularity of region deposit evolvement that made gas content larger in whole west of Guizhou.

When coalbed water is under a certain closed condition, coalbed reservoir has a higher pressure and a great gas content.

As the soft coal seam is high gas content and low permeability. it has been difficult and key for the coal seam gas extraction.

At present, the screw pump is widely used in exploiting crude oil with high viscosity, high sediment concentration or high gas content.

The method is simple and reliable in calculation, and is useful for predicting distribution characteristics of coal-seam gas content.

But since the high coal bed gas content and concentration largely affected coalmine safety in production.

The adsorption time of coal sample has a positive correlation with gas content and fracture growth.

When the explosion occurred, several miners working underground testing and installation of ventilation equipment, gas content.

Deep-hole presplitting explosion in coal seams with high gas content and low permeability was numerically simulated and analyzed.

The gas content is a critical parameter in resource calculation, and target selection and evaluation of coalbed methane.

Major factors affecting gas content are buried depth of coal seams(pressure and temperature) and magma intrusion.

The desorption rate has a positive correlation with gas content in coal, and has a negative correlation with ash constituent.

Of course, more gas content in molten steel causes that steel billets come into being the subcutaneous bubble is also important reason.

It is showed that the main reason of error on measure results of noxious gas content after blasting is the use of cannon expanding.

However, in areas with weaker hydrodynamics , or stagnant area, the coal usually has high gas content.

The results show that gas geology cell should be taken into account to analyse gas content.

the more the dissolved gas content is, the better the stability of foaming oil is.

Gas content varies as depth of burial, the thickness of roof clay rocks, and working thickness.

According to the coal seam gas content formula, the gas pressure in different freezing temperature was calculated.

Data range and spatial distrbution of gas content and reservoir pressure in unknown area was predicted by using simulation results.

So it is feasible used the logging data to forecast coal seam gas content, and the applied value is enhance further.

We also forecast the gas content by multiple regression.

These factors will decide the physical chemistry properties of hydrate, such as its structure, reaction velocity, gas content, etc.

But during coal mining, often stop production because of gas content in natural coke increase.
