摘　　要：南海南部北康盆地具有良好的油气资源条件,但我国无钻井。这里收集了该区内Mulu-1井部分测井曲线以及Talang-1井的钻探结果,利用有限的钻井数据进行该区的储层预测与含油气性检测。引入弹性参数旋转角度,构建了岩性及流体指示因子,并根据反演获得了研究区内两个目标钻井的指示因子。结果表明,通过Mulu-1井测井数据交会分析,新的指示因子较常规参数具有更好的敏感性;在储层品质较好且有油气发现的Talang-1井处,反演结果与实际钻井结果吻合,表明提出的方法在该区具有较好的实际应用效果,对南海南部的油气勘探具有一定的价值。The Beikang basin in south of the South China sea is a region with good oil and gas resources,but there is no drilling of China.In this paper,some logging curves of Mulu-1 well and drilling results of Talang-1 well are collected.It is proposed to use limited drilling data for reservoir prediction and oil-gas detection in this area.The rotation angle of elastic parameters,constructs lithology and fluid indication factors are introduced,and the indication factors of two target drilling wells in the research area are obtained according to the inversion.The results show that the new indicator is more sensitive to the parameters than the conventional ones through the cross-plot analysis of well logging data in Mulu-1;in the well Talang-1 with good reservoir quality and oil and gas discovery,the inversion results are consistent with the actual drilling results.The method proposed in this paper has well practical application effect in this area,and has certain value for the oil and gas exploration in the south of South China sea.
