均质性

By analyses, the main reason of poor reservoir heterogeneity is the change of depositional environment.

综合分析认为，引起储层非均质性的主要原因是沉积环境的变化。

As a result, in integrating data the critical question is how to take advantage of 3D seismic data and well data to descript petroleum no homogeneous.

因此，数据综合中典型的问题是如何利用3D地震资料和井资料来更好地描述油藏的非均质性。

Sulige Gas Field has low porosity, low permeability, low abundance, strong heterogeneity, complicate geological condition and is not very good at effective sand body continuity and connectivity, and so on. It is observed that gas well productivity of this gas reservoir is low, formation energy supply not enough, single well drainable gas is finite.

苏里格气田具有低孔、低渗、低丰度，非均质性强和有效砂体连续性、连通性差等特征；从已有的试井动态资料可以看出，该类气藏气井产能较低，地层能量供给不足，单井可采气量有限。

Firstly, pressure, enthalpy, temperature and velocity of pure water at different location of hydrothermal circulation system are described. Density and viscosity of fluid are calculated from temperature and pressure using properties of pure water. Secondly, influences of formational anisotropy and crack zone on hydrothermal circulation are analyzed.

首先讨论了热液循环系统不同部位的压力、焓、温度、水流的密度、粘度及流动速度等参数的特征，其次分析了地层非均质性、裂缝带的存在对热液循环流场的影响，最后分别模拟了近临界状态及侵入体存在情况下的热液循环。

In fractural area, because the elasticity is heterogeneity, seismic wave absorbed and scattering, the seismic record is more complex. Thus, the Hurst exponent in fractural area is less than in non-fractural one.

在裂缝发育区段，由于地层介质弹性的非均质性及地震波的散射、吸收等使得地震反射序列变得更为复杂，这样，裂缝发育区地震信号的赫斯特指数小于非裂缝发育区。

So, the strain gradients and consequently the related gradients of mechanical properties are closely linked to hydric heterogeneities generated by non-uniform drying in the layer of material.

因此，应变梯度，因此有关梯度的力学性能有着密切的联系氢气所产生的非均质性非均匀干燥在一层的材料。

Around these targets mentioned above,the research orientation and tentative recommendations about recognition of intraformational heterogeneity in channel sandbodies are proposed by exemplification.

围绕这些目标，通过例证提出重新认识河流砂体层内非均质性设想建议和研究方向。

Channel sandbody; reservoir intraformational heterogeneity; mature oilfield; tapping potential of remaining oil

河道砂体；储层层内非均质性；成熟油田；挖掘剩余油潜力

The intraformational heterogeneity controls and affects the swept volume of the injectant in single sand layer, directly determines the waterflood efficiency, and is the key factor influencing the distribution of the remaining oil.

为此采用了细分开发层系、分层注水、开展流动单元精细研究等地质和开发措施，可以有效地降低各类非均质性对油藏最终采收率的影响。

The simulations also show that on gas displacement front , CO2 drive is gas expansion drive when CO2／N2 slug, intraformational heterogeneity is more important than gravity segregation for the gas flooding of low permeable oil reservoir .

此外，对于低渗油藏，气驱主要受层间非均质性的影响，重力超覆影响较小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
