海南邊界斷層下降盤分別發育近岸水下扇、扇三角洲和三角洲沉積。海南2號斷層下降盤及深水區域濁積扇沉積發育。 -
The submarine fan with completely inner, middle and outer fan can be divided into progressive and regressive sequence, which were composed of sandstone bodies formed by turbidity flow
海底扇具有完整的內扇、中扇與外扇組合，可劃分出進積型和退積型兩種序列類型，它們多半是由濁流形成的各種砂體組成的。 -
In the chronstratigraphic framework, the facies, the depositional system and the principle and range of reservoirs distribution are studied. the main depositional system is braided delta ? ub - lake fan. the coarse lithofacies which form braided delta depositional system is sub - water channel deposits ; the coarse lithofacies which form the sub - lake fan depositional system include turbidity channel deposits and bedded turbidity deposits
在等時地層格架內，總結了各個中期旋迴的沉積相類型、沉積體系和展布規律及范圍，認為研究區在該時期以辮狀三角洲?湖底扇沉積為主；構成辮狀三角洲的粗碎屑相為水下分支河道；構成湖底扇的粗碎屑相包括：濁流水道相、層狀濁積巖相。 -
The most favourable sequences for subtle traps are cycle 3 and cycle 4, and the most favourable oil and gas - pool forming regions are jishan sandstone, fan - delta sandstone of south part of linnan sag, sliding turbidity sandstone of the slope part of shuangfen delta front and turbidity and sub - fan near fault of jiangjia dian
基山砂體、臨南窪陷南部沙三下扇三角洲砂體、雙豐三角洲前緣的斜坡地帶的滑塌濁積巖砂體和江家店地區的濁積扇體和近岸水下扇體是最有利的勘探目標區。 -
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果看，本區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育區。 -
According to paleo - geomorphology and depositional systems analysis, three kinds of forming models of subtle traps were built. they are fan - delta front - slope - sliding turbidity subtle traps n sub - fan near fault - stepping faults - turbidity subtle traps and fan - delta - furrow - sub - fan - sliding turbidity subtle traps
綜合分析表明，臨南窪陷具有有利的油氣成藏條件，發育有上傾尖滅型隱蔽油氣藏、透鏡體隱蔽油氣藏、斷層-巖性隱蔽油氣藏等隱蔽油氣藏。 -
Seismic inversion results indicate that the delta sandstone reservoirs occurred extensively in the 2nd and 3rd intervals of dongying formation, lower tertiary, and become poor only to the western margin of the survey area. in contrast, the fan delta sandstones in shahejie formation developed mainly in the area between fl and f2 faults, and turbidity sandstones locally in the rest of the survey area
儲層預測結果表明，東二、三段儲層除工區北部西側外，普遍發育較好；而沙河街一、二段和沙三段儲層主要集中在f1斷層下盤的中臺階地區及f2斷層下盤，其它地區發育一些規模不等的濁積扇。
