摘要
A区Z7油藏目前处于压力保持水平低、采油速度低、采出程度低、单井产量低的“四低”状态,同时储层非均质性强,隔夹层发育,老井改造规模有限,纵向动用不充分,剩余油丰富。通过储层单砂体刻画、隔夹层分布特征以及隔夹层对剩余油的影响作用研究,总结隔夹层对剩余油分布的影响规律,为油藏下一步开发调整和提高原油采收率提供可靠依据。
The A block Z7 reservoir is currently in the "Four-Low" state of low pressure maintenance level, low oil recovery rate, low degree of reserve recovery and low oil production per well. At the same time, the reservoir is characterized by strong heterogeneity, barrier and interlayer are well developed, renovation of old wells is limited in scale, longitudinal reservoir is not fully utilized, and the remaining oil is enriched. Through the study on the characterization of single sand body in reservoir, the distribution characteristics of barrier and interlayer, and the influence of barrier and interlayer on remaining oil. Summarize the influence rule of barrier and interlayer on the distribution of remaining oil, provide reliable evidence for the further development and adjustment of the reservoir and the improvement of oil recovery.
