查询词典 alluvial sand

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

It can be seen from the results that: water potential in quartz sand layer decreases with increasing thickness of the quartz sand layer under fixed sprinkling rate and increases with increasing sprinkling rate under fixed thickness of quartz sand layer; some of water above quartz sand layer flows down through the quartz sand layer and some flows down along edges of the quartz sand layer; some of water detoured the quartz sand layer flows into the region below the quartz sand layer closely along lower surface of the quartz sand layer.

The study results show that:①The distribution of Cd in shallow surface soils is characterized as: The content of Cd in lacustrine deposit, alluvial lacustrine and alluvial-diluvial low-lying plain is 1.4 to 1.8 times as high as in alluvial-diluvial high valley flat and alluvial-diluvial high bank physiognomy areas.②The content variation of Cd in horizontal distribution was controlled by clay primarily and OrgC secondly. The variation of OrgC was major factor that affected the content variation of Cd in vertical distribution.
