The models for calculating formation fracturing pressure are obtained on the basis of fracturing criterion, and the reliability of these models is proved by the comparison of the calculated formation fracturing pressures of several wells in an oilfield with the actu...

结果表明，运用断裂理论建立的破裂压力计算模型由于考虑了裂隙的存在，与地层的实际更为吻合，因而准确性更高，适用范围更广。其计算结果与现场实测值更为接近，从而也验证了模型的可靠性。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

Combining the temperature distribution of wellbores with the temperature distribution of formations, we construct a closed and conservative equation group with initial and boundary conditions.

把井筒和地层的温度分布有机结合起来，建立起一个封闭的具有初边值条件的守恒的方程组系。

This phenomenon is related to the REEs sources(gyration and discontinuity eruption Emeishan basalt) and the transgression-regression frequently.So...

因此，在具有相同物源的地区，可以利用稀土含量的变化，进行煤层和地层的对比、划分，并有可能研究海平面的变化。

Some authors proposed that the analyses of transfer cycles of high frequency base level and key surface correlation could be used to correlate isochronal strata.

在前人提出的高频基准面转换旋回分析和关键界面对比分析来确定等时性的基础上，以板中东油田板2油组水下冲积扇沉积为例，就湖盆内事件沉积的特点，提出可以结合洪泛面和事件沉积界面以及异旋回和自旋回来进行高分辨率层序地层的对比研究。

We will also explore topics like sediment transport and deposition in modern sedimentary environments, burial and lithification, survey of major sedimentary rock types, stratigraphic relationships of sedimentary basins, and evolution of sedimentary processes through geologic time.

我们也将会探讨以下题目，例如沉积物搬运和现代沉积环境中的沉积作用，埋藏和石化作用，观测主要的沉积岩类型，沉积盆地中地层的关系，和地质时期沉积过程的演变。

Note that in areas of monoclinal dip the closure of atrap may not be the same as its structural relief.

值得注意的是，在只有单斜地层的构造内，圈闭的幅度可能与构造的起伏不一样。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
