低幅度复杂断块油藏由于沉积环境复杂,油田范围内断层非常发育,构造复杂,断块多而小,储层横向变化大,储层非均质性严重,岩石成分复杂,岩电关系不清,导致油层识别难度大。同时由于含油高度低,导致含水上升快。具有多套油水系统,油水关系复杂,勘探开发难度较大。 Due to the complex depositional environment, faults with low-amplitude and complex fault-block reservoirs are characterized by complex faults, multi-and small fault blocks, large horizontal variation of reservoir, serious reservoir heterogeneity, complicated rock composition and no relationship between rock and electricity Clear, resulting in reservoir identification difficult. At the same time due to the low oil level, resulting in faster water cut. With multiple sets of oil and water systems, oil and water complex relationship, exploration and development more difficult.
