针对文中油田文209块高含水期存在的构造复杂,认识程度相对较低,剩余油分布零散,认识和挖潜难度大等突出问题,通过开展地层精细对比、构造精细研究、沉积微相研究、储层非均质性综合研究、剩余油分布规律研究等多项专题研究。理顺了内部次级断层的组合与配置关系,深化了区块构造格局的认识,重新认识沉积相类型,明确了沉积微相与不同类别储层之间的对应关系,并通过密网格精细油藏数值模拟,在此基础上采用剩余可动油储量丰度研究剩余油,准确定量地反映剩余油潜力的富集分布,明确了本区剩余油分布特征及规律,针对性地提出油藏调整治理方案。
Aiming at the prominent problems such as complex structure, low level of awareness, scattered residual oil, difficulty in recognizing and tapping the potential of Wenzhong Oilfield Wen 209 block in high water cut period, the author carried out a series of studies such as fine stratigraphic correlation, fine structure study, sedimentary microfacies study, Layer heterogeneity comprehensive study, the remaining oil distribution research and many other topics. Stratified the combination and arrangement of internal secondary faults, deepened the understanding of the block structure pattern, re-recognized the sedimentary facies, clarified the correspondence between sedimentary microfacies and different types of reservoirs, Reservoir numerical simulation. Based on this, the residual oil was studied by using the remaining oil reserves. The enrichment and distribution of residual oil potential was accurately and quantitatively reflected. The distribution characteristics and laws of remaining oil in this area were clarified. Adjust the management plan.
