PREDICTION OF RESIDUAL OIL DISTRIBUTION IN COMPLEX FAULT-BLOCK DISTRICTS DURING HIGH WATER-BEARING PERIODS
-
摘要: 通过对复杂断块油田马厂油田的精细表征,在该区划分了9级储层层次,其中五级和六级是本次研究的对象,并以五级层次为制图单位形成了储层建筑结构模型。结合砂体非均质性特征,总结了8种注入水波及方式,并应用容积法计算了注入水波及面积。确定了剩余油分布区,并结合储层表征结果,将剩余油分为井网未控制型、结构要素拼合型、井间干扰型和层内干扰型4种富集样式。对研究层段的潜力评价表明,该区潜力较小,已不可能维持目前的产量水平。Abstract: In the characterization of fault-blocked Machang oilfield,nine scale reservoir architectures were founded,of which the fifth and sixth order became the main subjects for characterization in the study.With the fifth order as the mapping unit,the reservoir structural model was established.According to re-servoir heterogeneity,eight types of water injection patterns were identified.The high residual oil areas were determined through injecting-water volume analysis.The residual oil belonged to four patterns as following:oil not controlled by the production well-net,oil remained for architecture element contacting,oil between two injection wells and oil remained for injection interfering.The residual oil appraisal indicated that the reservoirs were well developed,and it is difficult to maintain their production as usual.
