摘要
胜利山柳沟北部油区存在油层能量利用不足、井场状态不理想、注采井网不完善等问题,在很大程度上影响了油田的开发效果.基于此,针对低渗透油藏的特征,通过考虑地层压力的合理维持、采用菱形反九点井网形式、综合经济评价确定井网密度,以及物质平衡方法计算合理注采比等措施,实现了更加经济高效的油田开发.最终提出的开发调整方案有助于提高地层压力、优化井网结构,以及保障油田的可持续开发.这些调整为新建产能提供了可行的方案.
Abstract
There are some problems in the north Liugou oil area of Shengli Mountain,such as insufficient utilization of reservoir energy,unsatisfactory state of well site and imperfect injection and production well pattern,which affect the development effect of oilfield to a great extent.Based on this,in view of the characteristics of low permeability reservoir,this paper realizes more economical and efficient oilfield development by considering the reasonable maintenance of formation pressure,adopting the rhombic reverse nine-point well pattern,determining the well pattern density by comprehensive economic evaluation,and calculating the reasonable injection-production ratio by material balance method.The final development adjustment plan is helpful to increase formation pressure,optimize well pattern structure,and ensure the sustainable development of the field.These adjustments provide a feasible plan for new production capacity.
