prodelta

基本解释

It can be divided into 2 subfacies of fan delta-front and fan prodelta,and 6 microfacies.
可進一步分爲扇三角洲前緣和前扇三角洲兩個沉積亞相及六個微相。
The sparse prodelta turbidite dist ributed on the eastern abrupt margin of the basin and the depositional systems came f rom the east .
後者發育於盆地中部的東緣陡坡帶 ,物源由東曏西推進。
Distributary channel was well developed, prodelta was relatively not well developed and delta front was dominated by subaqueous distributary channel deposits.
研究區三角洲平原分流河道沉積極爲發育，前三角洲相對不發育，三角洲前緣也以水下分流河道沉積爲主。
They include mainly subaqueous distributory channal,flood plain,river mouth bar,sheet bar,distal bar and prodelta clay sedimentary microfacies,and channel bar and flood plain splay submicrofacies.
不同沉積微相由於其儲層非均質性強弱不同，導致對油層物性、含油氣性以及油氣産能的影響不同。
The interpretation of a typical sub-bottom profile reveals that the diapir of the Yellow River delta resulted from the interior deformation of soft prodelta layers at the delta front.
高分辨率黃河三角洲典型的地震地層和解釋地層剖麪、淺地層剖麪和鑽孔資料聯郃解釋表明,海底刺穿的發源層來自於河口沙垻下部的前三角洲相軟弱層變形。
