【摘要】 自2002年以来,针对济阳坳陷勘探现实,从陆相断陷盆地独特的石油地质条件分析入手,坚定隐蔽油气藏可以成为主要储量接替阵地的基本判断,以油气成藏理论和勘探关键技术为主要内容开展攻关,深化断陷盆地构造、沉积、成藏规律3项重点研究,在咸化湖泊环境烃源岩的高效生排烃机制、断陷湖盆缓坡滨浅湖滩坝砂体成因成藏机制、断陷盆地油藏分布连续性及有序性特征等方面取得创新认识。大面积推广应用针对复杂地质目标的高精度地震勘探技术,研发并形成了超高温深层射孔与压裂技术,拓宽了深层油气藏勘探开发空间。突出风险勘探和预探,新领域不断取得突破,连续实现三级(探明、控制、预测)储量年均超过亿吨,为胜利油田原油稳产作出了贡献。更多还原

【Abstract】 Based on actual exploration conditions of Jiyang depression,we analyze unique petroleum geological conditions in the continental rift basin,follow the basic judgment that subtle reservoirs can become the main reserve replacement position,take oil and gas accumulation theory and key exploration technologies as main contents to tackle the exploration problem,and deepen the researches of the rift basin structure,deposition and accumulation law.Consequently,some innovative understandings have been obtained since 2002,such as the efficient hydrocarbon generation and expulsion mechanism of hydrocarbon source rock in the brackish lake environment,the origin and reservoir formation mechanism of gentle slope shore-shallow lake-beach-dam sand body in the rift lake basin,continuity and orderliness of reservoir distribution in the rift basin.Besides,China promotes excessive application of high-precision seismic exploration technology for complex geological targets in this area,develops and forms ultra-high temperature deep perforating and fracturing technology,which broadens exploration and development of deep hydrocarbon reservoir.Risk exploration and pre-exploration are highlighted.Breakthroughs are made continuously in new fields.Annual average three-level(proven,controlled and predicted) reserves have exceeded one hundred million tons for many consecutive years and all of these make contributions to stable annual oil yield in Shengli Oilfield.更多还原
