摘要
针对柴达木盆地狮子沟N1油藏高含水阶段平面、层间矛盾突出,储量评价手段单一等问题,综合地质、测井等资料,建立了精细三维地质模型,在模型的基础上开展了储层非均质性研究、概率储量计算以及历史拟合一体化研究.研究表明,N1油藏主力小层含水突破是由于存在渗流优势通道,II-39小层非均质性强;储量分布不确定性大,用100口井的资料计算得到储量为230×104～264×104t;通过历史拟合一体化研究,精确的拟合SZ23井含水突破过程.应用地质建模技术开展开发地质研究,信息量大、精度高,提高了工作效率,并为高含水期剩余油挖潜指明了方向.
The Shizigou N1 reservoir in the Qaidam Basin has entered into high water cut stage.The areal and interlayer contradiction become obvious and the reserves evaluation methods are limited.Reservoir heterogeneity and probabilistic reserves calculation are carried out on the basis of the geological modeling,which based on geological and logging data.The research shows that water breakthrough of the main layer in Shizigou N1 reservoir due to the presence of seepage channel.The reserves,calculated with 100 wells,are between 230×104t and 264×104t of great uncertainty.History matching is carried out on the basis of geological modeling.Water breakthrough process is accurate fitting.The development geologic research conducted by using geological modeling,provides abundant of information with high accuracy,improves the work efficiency,and points out the direction for remaining oil development in high water cut stage.
