Near shore sub - aqueous fans , fan delta and delta occurred on the footwall of the hainan marginal fault , whereas turbidity fans developed in the deep water area and the footwall of the hainan no . 2 fault 海南邊界斷層下降盤分別發(fā)育近岸水下扇、扇三角洲和三角洲沉積。海南2號斷層下降盤及深水區(qū)域濁積扇沉積發(fā)育。
Therefore , we can conclude from the predictions of reservoirs and pressure in the area that the major exploration prospects should be the reservoirs between the fl and f2 faults and the turbidity fan sandstones in the down - block of f2 fault F5斷層封堵性能相對較差。從儲層預測和壓力預測結(jié)果看,本區(qū)沙河街組的勘探重點應該放到中臺階及下臺階二號斷層下盤附近的濁積體發(fā)育區(qū)。
