摘要: 针对南泥湾油田特点,确定适合本区地质及油藏工程特点的工业油流标准,提高该类油田储量的计算精度.应用数值模拟、类比等方法,结果显示,南泥湾这类必须经过压裂改造的特低渗油藏,单井产量仍然按照双曲线递减规律;工业油流标准的确定,需要准确把握单井平均总投资、原油利润、收回单井总投资的单井产量等参数,在此基础上确定的工业油流标准更能满足生产需要,对储量计算、滚动开发建产、管理者决策具有十分重要的意义.

Abstract: In order to find industrial oil output standard to fit for the geology and reservoir engineering in Nanniwan oilfield.Based on the analogy and numerical value simulation,the results show that a well output still fit for the double decline curves after being fractured.To get an industrial oil output value,you must know the investment of a well,oil interest,the output value of reclaim a well etc.This value can fit for the production,calculate the reservoir,and roll development and the manager to make a strategic decision as well.
