摘要
留西油田为低渗透复杂断块油藏。油藏构造破碎,断层多,断块多,勘探开发难度大;砂层厚度大,平面变化快,隔夹层分布不稳定,储层非均质严重;储层物性差,开发中出现注水压力高,吸水能力差,油井能量低,采液强度低,纵向动用程度不均。结合数模和动态分析对留17断块进行了储量动用程度评价。从Eclipse数模模型中导出剩余油储量,然后利用C++编程将其转换为surfer格式的数据,并在surfer中进行运算,得到剩余油储量,根据原始储量丰度,计算出动用程度等。
Liuxi oil field is a complex fault block oil reservoir with low permeability. Reservoir construction is broken,there are many faults and meny fault blocks so it is difficult for exploration and development. Sand layer is thick; flat changes quickly and separates laminates distribute unstably. Reservoir heterogeneity is serious ; reservoir physical property is poor,water flooding pressure occurs in developing and water absorption ability is poor; low-energy wells have fluid characteristics of low intensity. From Eclipse Digital-analog model,get the remaining oil reserves,then use C++ programming to convert it to Suffer-format data,and conduct operations in suffer,so get the remaining oil reserves,at last according to the original reserves abundance,calculate the production.
