On the basis of the previous studies and geographical conditions in Qaidam Basin, we suggested that the early diagenesis partly converted the fatty acid amide into the fatty nitrile.

结合研究区域的实际情况及前人的研究成果认为早期成岩作用使来源于各种生物体的脂肪酸酰胺类分子化石部分地转化为脂肪腈类化合物。

According to previous studies and geographical conditions of the Qaidam Basin, the authors hold that the early diagenesis partly converted the fatty acid amide into the fatty nitrile.

The geochemical studies of the basalts indicate crustal contamination increases from the inland to the coast along the volcanic belt, and therefore show different degrees of crustmantle interactions.

Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.

样品在纵波速度－泊松比交汇图中表现出两种主要变化趋势，分别对应泥质与钙质胶结物的影响；在每个变化趋势中随泥质含量与钙质胶结物含量的增加，岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑，弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播，这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因，为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。

The stratum frame of Yanchang formation in Yan'an area is founded with the sequence-stratigraphy, Chang 6 is anatomised in detail.

分析研究区岩石成岩作用，利用岩心观察、薄片、粒度、常规物性、敏感性、压汞、电镜扫描和实验等多种方法对研究区储层进行分析研究。

The content and size of the plastic grains in the reservoir clasts are important factors controlling the reservoir property. Diageneses are a crucial factor of reservoir property, in which consolidation heavily affected reservoir property, cementation was only an important controlling factor influencing reservoir property in the partial area and the influence of dissolution was weak.

储层碎屑组分中的塑性颗粒含量和粒径是储层性质的重要控制因素；成岩作用是储层性质的决定性因素，其中压实作用对储层性质的影响最大，胶结作用仅在局部地区成为重要的控制因素，溶蚀作用的影响是比较有限的。

The research result about abnormal pressure shows insufficiency of compaction disequilibrium as the sole cause of high pore fluid pressures, and tectonic compression, aquathermal expansion, diagenesis, hydrocarbon generation etc also can be the generating mechanisms.

一般认为欠压实是最主要的异常高压成因机制。由于构造挤压引起压应力的改变，由于水热膨胀、成岩作用、烃类生成等引起体积的膨胀，或由于流体流动和浮力作用也可产生异常超压。

More importantly, ferrimagnetic iron sulphide is found in Unit A2 but absent in Unit A1, suggesting the control of marine environmental conditions on the magnetic mineral diagenesis.

铁磁性硫化物存在于A2段，但在A1段缺失，表明了海洋环境条件对磁性矿物成岩过程的控制。
