中国南方区油页岩资源状况及开发目标优选

中国南方区包括长江以南的广东、海南、云南等10个省区以及江苏长江以南的区域。资源评价结果表明，南方区油页岩主要分布在广东、海南、广西等7个省和自治区、12个盆地、17个含矿区、23个勘查区和10个预测区。南方区油页岩资源为203.62 亿t，折算页岩油为11.93 亿t，其中油页岩查明资源为94.21 亿t，占全国油页岩查明资源的25.34％；油页岩探明的资源为45.60 亿t，占全国油页岩探明资源的58％。南方区油页岩质量较好、含油率大多在5％～10％。南方区油页岩主要分布在新生代，其次为中生代。为了更好地开发和利用油页岩资源，依据油页岩多参数优选标准及其排序结果，优选出最有利目标区10个、有利目标区3个、较有利目标区9个。综合优选排序结果和交通地理及开发条件等，确定出电白县羊角精查区等4个近期开发目标区和茂名煤田羊角井田等5个后备开发目标区。

Resource Status and Development Targets Selection of the Oil Shale in South China

South China includes ten provinces(municipality), such as Guangdong, Hainan, Yunnan, south of Yangzi River of Jiangsu, and so on. Present resource evaluation indicates that oil shale of south China are distributed in twelve basins, seventeen oil shale deposits, twenty three prospecting units and ten predicting units in seven provinces(municipality), including Guangdong, Hainan and Guangxi, and so on. Oil shale resource of South China is estimated at about 203.62×10⁸t, with converted shale oil of about 11.93×10⁸t. Among them discovered resource is estimated at about 94.21×10⁸t, account for 25.34％ of China total oil shale discovered; proved resource of South China is estimated at about 45.60×10⁸t, account for 58％ of China total oil shale resource proved. Oil shale resource of South China is mainly located in small half graben basins of Cenozoic and Mesozoic, their quality is better and oil yield could reach 5% to 10%. In order to exploit and utilize oil shale effectively, ten best target units, three better target units and nine good target units are selected based on multi parameters optimization standards and queuing results of oil shale exploitation targets. Combined the comprehensive optimization queuing results, traffic and geographical, and exploitation condition, four development targets in the near future (including the Yangjiao intense exploration area) and five development target reservation (including the Yangjiao well field of the Maoming coalfield) are determined in South China.
