摘　　要：对资源基础、构造背景、储层展布、油源断裂等岩性油藏成藏条件分析,明确长岭凹陷黑帝庙油层为"下生上储"的含油气组合,存在北部塔虎城地区砂岩上倾尖灭岩性油藏带,中部乾安地区断层-岩性油藏带,南部大情字井地区断层-岩性、岩性油藏带。运用三维地震储层预测、低阻油层识别、水平井+体积压裂等技术实施勘探,结果表明,塔虎城地区连片含油,乾安—大情字井老油田之上发现新的油藏。The analysis has been made on lithologic reservoir-forming conditions such as resource basis,structural background,reservoir extension,oil source faults. It is identified that Heidimiao Oil Layer in Changling Sage is an oil/gas assemblage of'generation in lower formation and accumulation in upper formation'. There are lithologic sandstone reservoir zone with upward pinchout in Tahucheng in the north,fault-lithologic reservoir zone in Qian'an Area in the middle area and fault-lithologic and lithologic reservoir zones in Daqingzijing Area in the south. The 3D seismic reservoir prediction,low-resistance oil/gas identification and horizontal well + volumetric fracturing are applied for the exploration. Results indicate that,there are connected oil zones in Tahucheng. New oil reservoir above mature oilfield in Qian'an – Daqingzijing has been discovered.
