【摘要】 针对沾化西部地层圈闭识别、落实和评价难及钻前预测可靠程度低的特点,从勘探实践出发,总结出一套行之有效的地层油气藏勘探综合评价技术,即:以高精度层序分析建格架、构造分析划区带、不整合研究定靶区、"三线"研究描圈闭、沉积相带找储层及综合评价选目标构建的"六步法"评价方法。该技术系列在胜利油田沾化西部地区多个区块超覆油藏勘探中取得了良好的应用效果,显示其在地层油藏勘探中巨大的应用潜力。更多还原

【Abstract】 Aimed at being difficult to identify and evaluate the stratigraphic traps,and low reliability of reservoir prediction before drilling in the west of Zhanhua area,and based on the exploration conditions,a set of efficacious comprehensive technology on stratigraphic reservoir evaluation are developed,called "Six-step" evaluation method,which consist of the high accuracy sequence analysis to construct framework,structural analysis to divide the tectonic zone,unconformity characteristic research to confirm the target,"Three Lines"research to describe trap,deposition facies analysis to identify reservoir and comprehensive evaluation to select the zone of interests.The technique series has got good application effect on many blocks in the west of Zhanhua Depression of Shengli Oilfield,and it shows that this technique has great application potential in the stratigraphic reservoir exploration.更多还原
