摘要
目前北部湾盆地涠西南油区整体已进入高成熟勘探阶段,勘探开发目标逐步转向复杂小断块和隐蔽油气藏。为了实现涠西南凹陷资源效益的最大化及油田可持续发展,在陆上油气田滚动勘探开发经验的基础上,提出了涠西南凹陷滚动勘探开发的基本思路,并制定了相应的具体对策,即以区域油气成藏规律为指导,精细落实圈闭,强调区域资料类比分析,规避评价风险,加强区域储量参数规律认识,把控资源规模,进而为整体方案编制,钻探井位优选提供决策依据。实践表明,涠西南凹陷陆相复杂断块油气区实施滚动勘探开发,是实现增储上产、油气田投资效益最大化及油田可持续发展的必经之路,对国内海上其他地区滚动勘探开发的深入开展具有借鉴意义。
Oil regions in Weixinan sag of Beibuwan basin have entered a highly mature exploration stage and the complex small fault-block and subtle reservoirs gradually become exploration targets. To achieve the resource maximization and sustainable development of oilfield, progressive exploration and development in Weixinan sag was put forward based on the successful experience of onshore oil fields. The strategy was established to provide basis for the overall development program and drilling well location optimization, which included accurately fulfilling traps by reservoir-forming rule, avoiding evaluation risk by analogical analysis, controlling resources scale by reservoir parameters distribution analysis. The practice shows that progressive exploration and development carried out in complex fault-block oil-gas areas of Weixinan sag is the only path for reserve growth, benefit maximization and sustainable development of oilfield, which can guide the progressive exploration and development for other domestic offshore areas.
