萨北开发区东过渡带剩余油分布规律研究

Study on Remaining Oil Distribution Regular and Its Exploitation Strategy in East Transition Zone of North Saertu Development Area

目前萨北开发区东过渡带在开发过程中存在着原油粘度高、水驱控制程度低、采油速度、采液强度不均衡、油层动用差、油水井数比不合理等问题。因此,分析过渡带地区剩余油潜力分布,并依据过渡带地区的开发现状研究过渡带的开发调整及治理对策,对改善过渡带地区的开发效果有着深远的意义。结合萨北开发区实况资料,运用Eclipse数值模拟软件对东过渡带剩余油进行分类研究,并对东过渡带各油层组、各条带进行量化分析。

Nowadays, there are problems in development of east transition zone of north Saertu development area, such as high crude oil viscosity, little sweep efficiency, slow oil recovery rate, unbalance between liquid production rate and fluid producing intensity, and so on. Therefore, to analyze the remaining oil distribution has important significance to the east transition zone of north Saertu development area. It can help us propose the way to adjust the well pattern according to the present situation of east transition zone of north Saertu development area. In this paper, according to development data of east transition zone of north Saertu, the software Eclipse was used to research the remaining oil classification, quantitative analysis of every oil layers and every belts was analyzed.
