利用博尔努盆地内23口探井的钻井、测井资料,借助于Excel、Petrel及Surfer等软件,确定了盆地Kerri-Kerri组、Gombe组、Fika组、Gongila组和Bima组及整个沉积地层的空间分布.对整个沉积地层空间分布研究发现,博尔努盆地共有3个主要坳陷(A、C、D)和1个构造高点B.坳陷A位于盆地东北部,坳陷C和D分别位于盆地东南部和西南部,构造高点B分隔坳陷A和坳陷C. Kerri-Kerri组、Gombe组、Fika组、Gongila组和Bima组在盆地广泛分布,但地层厚度存在变化;3口深层探井(Kadaru-1井、Herwa-1井及Kinasar-1井)仅钻揭Bima组上部层段(岩性为中—粗粒长石砂岩),对Bima组下部层段尚未钻遇.因此建议针对盆地内部的潜在含油气坳陷区开展深层钻探.
