摘要:

瓦庄油田瓦6断块目前呈现产量递减,含水上升态势,开发过程中也暴露出非均质性严重、油水关系复杂、注水效果差、井网不完善等问题。针对该油藏的地质特点进行精细油藏描述,在精细小层对比划分的基础上,对储层微构造、沉积微相、储层物性和非均质性等进行了精细研究,利用沉积微相等研究成果约束储层参数的空间分布,建立起精细储层地质模型。在此基础上,对油藏进行数值模拟及剩余油分布研究,针对性地提出下步开发调整意见。

Abstract:

At present,there are some problems including production decline,water cut rising,serious heterogeneity,complicated oil-water relationship,poor waterflooding effectiveness,imperfect well pattern,etc.in W6 fault block in Wazhuang oilfield.On the basis of fine small layer contrast,fine research was made on reservoir microstructure,depositional microfacies,reservoir physical property,and heterogeneity.The fine reservoir geological model was built up by using above research achievements which restrain the spatial distribution of reservoir parameters.On this basis,numerical simulation and remaining oil distribution of the reservoir was conducted.Research results suggested schemes for further development and adjustment.
