摘　　要：新立油田扶杨油层为典型的曲流河三角洲相沉积,单砂体面积小、连续性差。就高含水开发期完善以单砂体为单元的微观注采井网作用进行阐述,提出适合高含水开发期评价井网完善程度的方法。结合新立油田不同沉积条件下单砂体井网不完善类型的分析,阐述采取井网综合利用等技术手段和对策。实践证明,该做法取得了良好的效果,对指导同类油田高含水开发期提高水驱控制程度、改善开发效果,挖掘剩余油潜力具有重要的参考价值。The Fuyang reservoir of Xinli oilfield belongs to typical meandering river delta facies,where single sand bodies have small areas and poor continuity.This paper addresses the improvement of microscopic injection-production pattern at high water cut stage by taking single sand body as unit,proposes a method of well pattern evaluation,analyzes the types of incomplete well patterns of single sand bodies under different depositional conditions,and explicates technical measures of comprehensive well pattern utilization for Xinli oilfield.It has been proved that this method has achieved good result and has important reference value to similar oilfields for improving the control degree of waterflooding and development response,and producing remaining oil at high water cut stage.
