1、大庆石油学院工程硕士专业学位论文喇嘛甸油田北北块聚驱上返方法研究摘要本论文从分析喇嘛甸油田北北块油层发育状况出发,利用精细地质研究成果,开展了油层地质特征研究,上返层系组合方式、注聚次序、井网部署等研究工作,取得了一系列的成果。首先是明确注聚接替油层应具备的条件:注聚层以河流相沉积的河道砂为主,河道砂钻遇率应达到40%以上;注聚单层以有效厚度大于1.0m油层为主;注聚层有效渗透率以大于0.1pm2的油层为主。其次,通过层系组合厚度界限分析,确定喇嘛甸油田北北块注聚层系组合有效厚度界限在8m左右。
2、根据数值模拟研究成果,明确聚驱层系组合时,主要油层渗透率级差应控制在2.5以内,避免将过多低渗透层组合进一套层系,为减少层问干扰,尽可能采取分层注聚措施。最后通过多方案层系组合对比,初步确定区块层系组合方式.首先上返萨1114.10油层,然后逐段上返萨二组油层,今后再次上返层系的确定可根据采油工艺的进步,认识的深化作进一步的调整。通过多方案对比,研究确定了北北块上返层系的开发布井方式,并进行了主要开发指标的预测。关键词:北北块;聚驱;二类油层:上返;方法大庆石油学院工程硕士专业学位论文Resea
