摘　　要：萨拉瓦提盆地位于印尼东部巴布亚岛的鸟头部分,萨拉瓦提盆地中新世发育的Kais组碳酸盐岩是东南亚第三系碳酸盐岩的主要勘探对象之一。Kais组生物礁是盆地的主要储层和产层。在前人对Kais组碳酸盐岩基本石油地质特征特别是沉积特征研究的基础上,结合中油印尼公司近年勘探的新资料,对Island地区Kais组生物礁圈闭类型进行了研究和成因划分,并在此基础上研究了萨拉瓦提盆地Island地区Kais生物礁圈闭的含油气特点与控油因素,提出并论证了礁体之间大都是连通的观点,认为萨拉瓦提盆地Island地区油气运聚的控制因素除与地层倾向一致的构造鼻和断层外,Kais组下部以生物滩相为主的碳酸盐岩本身就是较好的运载层。萨拉瓦提盆地具备油气差异聚集的独特条件,提出差异聚集可能是Island地区Kais组生物礁油气藏运聚的主要特征,也可能是控制油气藏相态的根本原因。Salawati Basin is located in the bird's head of the Papua Island, Eastern Indonesia. The Miocene Kais Formation's carbonate deposited in Salawati Basin is one of the main targets of the Tertiary in Southeast Asia. The reefs of Kais Formation are the main producing reservoirs. On the basis of previous study on the basic petroleum geology, especially the sedimentary characteristics, of the Kais carbonates combined with the latest data obtained from the PetroChina International in Indonesia in the recent years, the types and cause-forming of the reefs traps in Kais Formation have been divided,the petroliferous characteristics of the reefs traps in Kais Formation and the control factors have been analyzed. It is put forward and discussed that the reefs are connected, and thought that in addition that the structural noses and faults are the main passages of oil and gas accumulation, the reef oil reservoirs in the lower Kais Formation have the unique condition of oil and gas differential accumulation. The differential accumulation is probably the characteristics of oil and gas accumulation in the reef oil reservoirs of Kais Formation and probably the fundamental cause of controlling the phase state of oil reservoirs.
