解釋
礁沉積-
Based on available data, the study on regional structure, sedimentary reservoir and source rock characteristics shows that the basins in south china sea had experienced sedimentary evolution in faulting period and depression period, deposited thick cenozoic formation, upwardly developed alluvial fan facies, river - lake facies coastal swamp facies coastal facies, neritic facies and bathyal deposit system, regionally had 3 source rocks of eocene, oligocene and miocene, 3 reservoirs of pre - cenozoic basement buried bill, oligocene sandstone and miocene reef, with pliocene and pleistocene neritic facies and bathyal shale as regional caprock
摘要以現有資料為基礎，通過對區域構造、沉積儲層、烴源巖特徵等基礎石油地質條件研究，認為南海海域各盆地經歷了斷陷期和坳陷期沉積演化，沉積了巨厚的新生代地層，自下而上發育了沖積扇相、河湖相、濱岸沼澤相、濱海相、淺海相、半深海相沉積體系，區域上存在始新統、漸新統和中新統3套烴源巖，前新生代基巖潛山、漸新統砂巖、中新統生物礁3套儲層，區域蓋層為上新統和更新統淺海半深海相泥巖。 -
The results show that : 1 ) though the water environment of nanyisan is more muddy than others, algal can still grow ; 2 ) the composition and rock type of the algal limestone are complex, the main rock types include lettuce - like stromatolites, algal reef, digitate stromatolies, wave - like stromatolites and so on ; 3 ) the deposits of algal limestones were formed in low - energy peritidal to subtidal high - energy environment of lakeshore slopes, sliding under the action of gravity and some other factors and become slump mixosedimentite layers ; 4 ) the physical property of algal limestones layers is better than others ; 5 ) the genetic development of the sediment decides that the single deposit is small, distributive and thin - layed
結果表明，南翼山藻灰巖沉積水體環境相對渾濁，但藻類仍能生長；該區藻灰巖巖石組成及類型復雜，主要的藻灰巖巖石類型有包心菜狀疊層石、藻礁、指狀疊層石、水平波狀疊層石等；其主要為濱岸斜坡上低能潮上環境至高能潮下環境形成的沉積體，在重力等因素的作用下產生滑動或滑塌形成的微生物成因的滑塌混積巖；巖層物性好於其它巖層；藻灰巖層的成因決定了該地區單個沉積體規模小、分散、層薄。
