| 摘 要： | 石南21井区头屯河组油藏受构造、沉积微相、流体分布、注采井网和注采强度等因素的影响,不同区域开发效果差异较大,局部区域生产恶化。开展注采结构调整研究表明,对于油藏储量丰度低的区域调整为排式注采井网可取得较好的开发效果,采收率从39.2%提高至42.9%;而油藏丰度高的区域则采用加密调整的方式可取得较好开发效果,采收率从37.2%提高至43.6%.

| Abstract: | The Toutunhe reservoir in Shinan-21 Wellblock,affected by structure,sedimentary micro-facies,fluid distribution,injection-production well pattern and capacity,has varied development effects in different areas,and becomes poor in local part.The injection-production structural adjustment showed that for areas with low abundance of reserves,the original well pattern should be converted into row pattern,by which better development effect can be gained,and the recovery factor increased from 39.2% to 42.9%;while ... |
