摘要(Abstract)：
对老油田开发层系的重新评价与补充勘探 ,是增加石油天然气地质储量的重要途径之一。红岗构造是一个典型的长轴背斜构造 ,地层发育较全 ,具备多套有利的生、储、盖组合 ,因此在红岗油田开发 2 0年后对其新层系开展了重新评价与补充勘探。通过对红岗构造的整体剖析及不同层位的对比 ,弄清了该构造的油气控制因素及分布规律 ,并在此基础上进行了补充勘探。通过经济、有效的加密井加深、加密井加测横向、加密井生产试油和利用老探井试油等方法 ,发现了黑帝庙油气藏。在高台子油层找到了油气富集层位及富集区 ,建成了年产油 15× 10 4 t的生产能力 ,弄清了葡萄花油层的开发潜力。重新评价与补充勘探工作为红岗油田增加储量、产能建设和措施挖潜奠定了基础。
It is one of important approaches to increase oil and gas reserves that reevaluation and supplementary exploration of several new formations which below or above the layer series of development of an old field. This paper takes Honggang structure as the example,expounds the detailed methods and results. Honggang structure is a typical anticline structure.The structure has several favorable source reservoir cap combinations. By the way of analyzing and contrasting of upper and lower formations, the control factors and distribution laws of oil and gas are clear. On the foundation the supplementary exploration has been put in practice.The economic and effective methods of supplementary exploration is increasing depth, increasing log series, testing of infill wells, and testing of old exploration wells. Then the rich achievements have been obtained. Heidimiao reservoir is discovered. Gaotaizi reservoir is developed effectively. The production capacity of year 15×10 4 tons of oil is built up.The exploitation potential of Putaohua reservoir is clear at the same time.
