摘要: 416a-417区块位于阿尔及利亚中北部,目前只有二维地震资料,勘探程度较低,在油源条件、盖层与储盖组合、油气运聚模式、油气成藏控制因素以及目前已有探井钻井效果分析的基础上,对该区油气富集分布规律进行了综合分析和评价。在此基础上,结合区带评价结果,对416a-417区块构造带进行了优选,指出HJ-5、HJ-6两个构造圈闭处于有利的烃源岩发育区,是油气运移的有利指向区,具备优越的油气成藏条件,且圈闭幅度和面积较大、落实程度高、配套条件好,是416a-417区块勘探取得突破的首选目标。

Abstract: The 416a-417 block of Oued Mya basin is located in the middle-northern Algeria. There are only 2D seismic data available now, the exploration degree is relatively low. This paper presents the analysis of source conditions, reservoir-cap rock assemblage, hydrocarbon migration and accumulation model and control factors as well as drilling response, petroleum enrichment and distribution analyses. Integrated with play assessment result, the structural zone in the 416a-417 block is optimized. It is pointed out that HJ-5 and JH-6 structural traps lie in favorable area of source rocks development, which are the targets for petroleum migration with predominant conditions of hydrocarbon accumulation, large sealing area and amplitude. Because of high degree of study and good condition of collocation, this block could be a preferred target for petroleum prospecting in this area.

Key words: OUED Mye basin, 416a-417 block, reservoir model, structural trap, optimal target
