摘要
陈家庄油田为特高粘度稠油油藏 ,常规注水开采难度大。初期采用温和注水方式 ,水驱效果较好。但进入高含水期后 ,随着含水上升 ,单井产液量降低、地层能量下降快、停产井多的矛盾日益突出。近年来 ,充分利用不稳定试井技术 ,揭示油田深层次矛盾 ,通过强化注水工作及提液可行性研究 ,确定了合理注采比及合适的提液幅度。经过综合研究 ,实现了油田开发的新突破 。
Chenjiazhuang oilfield is an extrahighviscosity heavy oil reservoir. Common waterflood development is very difficult in this oilfield. Moderate waterflood is adopted at early stage achieving good response. In high water cut period, the contradictions of low fluid production of single well, fast formation energy dropping and more shutdown wells are becoming increasingly prominent along with the water cut increasing. In recent years, nonstabilized well test technique is fully applied to the discovery of deep contradictions in the oilfield. Reasonable injectionproduction ratio and fluid production increasing range are determined by the enhanced waterflood and feasibility research of fluid extraction. New breakthrough is realized in the oilfield development by comprehensive research, which provides experiences for the development in the same type of the oilfield.
