摘要
低渗透油藏井网加密后产量变化规律复杂,影响因素多,采用常规的Arps产量递减曲线拟合程度低,预测精度差,不能适应油田开发规划的需要。以Arps产量递减曲线法为基础,根据低渗透油藏开发的实际情况,综合考虑影响产量递减的各种因素,运用叠加原理,提出了一种新的产量递减分析方法。选用新的方法,可以比较准确地预测井网加密后的产量变化和评价井网加密后加密效果,它为低渗透油藏开发指标预测和评价提供了一种新的方法和手段。因此,该方法对于油田制定合理的开发规划以及指导油田下一步的加密调整工作,具有重要的理论和实践价值。
Arps decline curve is basic mathematic model used for studying oil/gas production decline rules, but it has disadvantage factors for production decline after well pattern infilling in low permeability reservoir. Based on basal reservoir engineering preciples and method of superposition, this paper presents a new mathematic method to analyze production decline curves. Using this method can improve greatly accuracy of production prediction and evaluate development effect after pattern infilling. It provides guidance evidence for further well pattern infilling.
