prodelta

基本解釋

It can be divided into 2 subfacies of fan delta-front and fan prodelta,and 6 microfacies.
可進一步分為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 .
后者發(fā)育于盆地中部的東緣陡坡帶 ,物源由東向西推進。
Distributary channel was well developed, prodelta was relatively not well developed and delta front was dominated by subaqueous distributary channel deposits.
研究區(qū)三角洲平原分流河道沉積極為發(fā)育，前三角洲相對不發(fā)育，三角洲前緣也以水下分流河道沉積為主。
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.
不同沉積微相由于其儲層非均質(zhì)性強弱不同，導(dǎo)致對油層物性、含油氣性以及油氣產(chǎn)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面、淺地層剖面和鉆孔資料聯(lián)合解釋表明,海底刺穿的發(fā)源層來自于河口沙壩下部的前三角洲相軟弱層變形。
