Chapter 4 of this dissertation has carried out a physical simulation study about the processes of formation and laws of evolution of the fan delta in Baimiao gas field. Based on the results of the study about the geological background in this area, this paper has discussed about the sedimentation facies marks for the fan delta in Baimiao gas field, worked out a detailed proposal about the development of physical simulation experiment about the fan delta, and described in detail the general laws and major controlling factors governing the sedimentation processes of the fan delta. A detailed measurement was made about the experimental results, and a systematic comparison was made relative to the prototypic characteristics. Based on the observation and description about the experimental processes and the analyses about the experimental results, this paper has give
在本章中,指出了数值模拟研究的基本特点,给出了扇三角洲形成过程的基本控制方程和数学解法:在此基础上设计和开发了扇三角洲形回成过程的平面二维数值模拟软件,并对计算过程中所遇到的主要问题一计算速度较慢开展研究,对比了以天、旬、月为时间单元进行汁算对沉积结果的影响,研究认为,在流量无突变的情况下,可以适当增长计算的时间步长和适当放松精度要求;根据白庙气田扇三角洲的基本地质特征设计了数值模拟计算的基本条件,以月为单位,计算了扇三角洲四百年的形成过程及演化规律,并以50年为单位输出沉积结果;本章最后还对数值模拟方法及结果进行了讨论。

The cation radical film exhibits an ageing effect, i.e. the changes in the physical or chemical properties of the film with time, following its deposition. It was found that because of a strong intermolecular interaction, ageing effect resulted in different aggregation states of cation radicals in the deposited film, and the film lost its reoxidation activity.
