The grain size of sediments has an important role in the early diagenesis of nitrogen.

在氮的早期成岩过程中，粒度也起着非常重要的作用，沉积物的粒度越细，沉积物中有机氮的分解速率越小，即细粒度沉积物中有机氮的分解矿化速率最小，易于富集有机氮。

Under the guidance of the theories of sedimentation, paleontology, stratigraphy, reservoir geology and digenesis, synthetically applying the methods of the conjunction of spot-line-surface, macro-microscopic and field-indoor, there is a comprehensive study for the upper Permian series in stratum, rock, sedimentary facies and diagenesis, especial for the type and characteristics of sedimentary facies, in the paper.

As the lake basin shoals and silts up, the color of clastic sediment gradually changes from black, black gray, gray and grayish green to purplish grey and red purple, meaning that the subaerial alluvial fan deposit of late stage has replaced the fan-delta deposit and that the coal-forming process ends.

待湖盆逐渐变浅和淤积，碎屑沉积物的颜色由黑、黑灰、灰、灰绿逐渐变为紫灰和紫红，表明晚期陆上冲积扇沉积已经代替了扇三角洲沉积，成煤作用随之结束。

There are three features in the minibasins induced by gravitational sliding on the slope: the firstly, feature is surface of unconformity developed by onlap on minibasin margins or surface of unconformity truncated by mass transport-complex are sequence boundary in the study area; the secondly , accommodation of gravity flow is controlled by up lift rate and sedimentation rate , and styles of filling in the minibasins are dominated by the interrelationship between the two factors; and the third , there are two stacking patterns that consists of upward of turbidite fan-hemipelagic drape mud or mass-transport complexes-turbidite fan-hemipelagic drape mud.

认为在深水陆坡重力滑动作用所形成的微盆地内，层序边界表现为微盆地边缘上超不整合面或重力流对下伏地层的侵蚀不整合；逆冲构造隆升速率与沉积速率共同控制了重力流可容空间和沉积充填样式；沉积垂向演化以块状搬运复合体一浊积扇－深海披覆泥或浊积扇－深海披覆泥为特征。

Tanshinone deposited on the surface of the carrier in crystal form, and the size was obviously reduced. A lot of acerose crystals of tanshinone on the surface of the carrier occurred. No chemical reaction acted between tanshinone and carrier.

结果：溶剂沉积物明显提高了丹参酮的溶出度；丹参酮以结晶形式沉积于载体表面，结晶颗粒与沉积前相比明显减小，且出现大量针状微晶；丹参酮与载体间仅仅是物理作用。

The activities in different sections of the Gaoqing fault in the Huagou gas field were analyzed using 3D seismic data. The activities of the fault segment associated with the Huagou gas field were strong during the Guantao\|Minghuazhen period, while the activities on east and west sides of the gas field were weak at that time. The Huagou gas field is well corresponding to the strong activity segment of the Gaoqing fault on the plane. The process of gas migration in the Huagou reservoir is divided into two phases:(1)After mantle\|derived magmatogenetic gas including CO2, N2, and He entered the Gaoqing fault, the gas migrated to the top of the fault by the action of buoyancy or pressure, then the gravitative differentiation occurred. For the top of the fault is closed and both sides of fault is sealed, the gas assembled to some degree in the Gaoqing fault;(2)When gas was accumulated at a large scale in the Gaoqing fault, the gas migrated towards the reservoirs along the two sides of the fault and was accumulated in sandstone.

利用三维地震资料，对济阳坳陷花沟CO2气藏区高青断裂走向上不同区段的活动性进行了分析，指出：花沟CO2气藏所对应的高青断裂区段，在馆陶组—明化镇组沉积时期活动性强，而气藏的东、西两侧，馆陶组—明化镇组沉积时期断裂基本上不活动；花沟CO2气藏与馆陶组—明化镇组沉积时期高青断裂活动性强的区段在平面上有着良好的对应关系；花沟CO2气藏的运聚过程分为2个阶段，在第1阶段，幔源岩浆成因的CO2、N2和He等气体进入高青断裂后，在浮力或压差作用下向断裂顶端运移，并发生重力分异，由于断裂顶端封闭、两侧封堵，CO2、N2和He等气体在高青断裂中实现了一定程度的聚集，而在第2阶段，当CO2、N2和He等气体在断裂中聚集到一定程度，便在压力驱动下向断裂两侧砂岩储层运移，并在其中聚集成藏。

It is the soil mass maintained by the umbrella-shaped root system of trees during the geological history,and it is formed by the interactive compression of tree load and growth of main root system and by the differential compaction of surrounding soil mass;in other words,it also is a kind of the sedimentary textite or sedimentary structure formed under the influences of biological process.

它是地质历史中，树木伞状根系所维系的土体，在树木的自重荷载和主干根系生长的相互挤压作用下与外围土体的差异压实造成的；换言之，它又是一种在生物作用影响下形成的沉积结构体或沉积构造。
