解釋
沼澤形成-
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。 -
Three sets of source rocks had been formed juring the steady sinking of the basin. the first source rock, being clay and calcium clay stone in tiemulike formation of permian was formed in deep lake environment ; the second source rock, being clay stone in xiaoquangou group of middle to upper triassic was formed in the offshore and the shallow lake environment ; and the third source rock, being coal beds in badaowan formation of lower jurassic was formed in the lake - swamp environment. the first one is the most potential, since it has the biggest thickness, the highest organic matter abundance, high maturity and the highest hydrogen generating capacity
在盆地穩定沉降時期，相應地形成三套烴源巖，即上二疊統鐵木里克組（ p _ （ 2t ） ）深湖、半深湖相泥巖、泥灰巖；中上三疊統小泉溝群（ t _ （ 2 - 3xq ） ）濱淺湖相泥巖及下侏羅統八道灣組（ j _ （ 1b ） ）湖沼相煤系地層。
