burial depth

Through mathematical statistics, the regression equations of relationship among burial depth, effective burial depth, thickness of coal seams and gas content has been gained and the test of significance on the equation was done.

通过数理统计的方法，得出了埋深、有效埋藏深度以及煤厚与煤层含气量的回归方程，并对回归方程进行了显著性检验。

The surplus pressure of gas reservoirs decreases along with increasing burial depth in the overpressure zones.

在超压带中,气藏的剩余压力随深度的增加而减小.

As sediments compact during burial, their density ( and hence their acoustic velocities ) generally increases with depth.

由于沉积物在埋藏过程中压实, 其密度和波速一般说来是随浓度而增加的.

We can locate the true depth of burial at the value.

我们能够算出这个值上的真实埋藏深度.

The research result indicated that one of development causes of dry soil layer is that burial depth of film water belt is small, which is decided by the a little precipitation; anthor is slowly moving speed of the film water and low moisture content.

研究表明，土壤干层形成的具体原因一是降水量少决定的薄膜水带埋藏深度小，二是薄膜水的运移速度缓慢和含水量低。

Burial depth control on the lead role of gas occurrence, most of the shallow is press-out, pour out, into a certain depth, the more performance is outstanding.

埋藏深度对瓦斯赋存起主导控制作用，浅部大多以压出、倾出为主，进入一定深度后，多表现为突出。

Subsurface temperature increases with burial depth might cause fluid expansion in most sedimentary basins.

在大多数沉积盆地中,地下温度随埋藏深度增高可能引起流体的膨胀.

In vertical, as for interlayer scale, oil saturation had no positive correlations with the porosity and permeability, while had some relations with the burial depth under the effect of petroleum accumulation environment.

垂向上，对于层间规模，代表储层内部油气分布的含油饱和度与储集物性不存在正相关关系，而是受成藏背景影响与深度存在一定对应关系。

In addition, it was shown that the deepest burial depth of generating immature oils is about 2800 meters in study area and the corresponding activation energy about 177 KJ/ mol.

并且进而提出本区低成熟石油的成油下限埋深划分至2800m为宜，其对应的下限反应活化能不超过177KJ／mol。
