摘要
LW3-1-1井位于珠江口盆地白云凹陷东部,是我国南海东部海域深水区第一口探井。通过对LW3-1-1井珠江组和珠海组共4个气层(Gas1—Gas4)砂岩样品流体包裹体荧光颜色、均一温度、油气包裹体丰度和成岩序次的分析,并结合埋藏史和热演化史的分析认为,LW3-1-1井珠江组和珠海组曾发生过两期油和一期气充注,主要来自恩平组和珠海组烃源岩,Gas1—Gas3层油气充注时间约在8—0Ma;Gas4层油气充注时间约在5—0Ma,Gas1和Gas2层油充注强度较大。
As the first exploration well in the deep water area of eastern South China Sea,Well LW3-1-1 is located in eastern Baiyun sag,Pearl River Mouth basin.The four industrial gas flow zones(Gas1-Gas4) are discovered in Zhujiang and Zhuhai Formations in this well.The fluorescence color,homogeneous temperature,hydrocarbon inclusion abundance and diagenesis order of fluid inclusions in the four gas zones are conducted.In combination with bury history and thermal evaluation history,the results show that the two periods of oil and one period of gas charging occurred in Zhujiang and Zhuhai Formations in this well.The hydrocarbons mainly derived from Enping and Zhuhai source rocks.The hydrocarbon charging time of Gas1-Gas3 zones and Gas4 zone is respectively about 8-0Ma and 5-0Ma,with relatively intensive oil charging in Gas1 and Gas2 zones.
