目的 为确定适合陕北特低渗油田的地方性工业油流标准,提高该类油田储量的计算精度。方法 应用数值模拟、类比等方法,确定该油田的工业油流标准。结果 按国家标准计算的工业油流值明显偏小,误差较大;运用产量递减法,并考虑到原油市场价格、油田开发投资、油气生产成本及原油利润等因素确定出新的地方性工业油流标准,更适合于陕北特低渗油田的实际。结论 新的工业油流标准可提高储量的计算精度,方便油田开发方案的调整,提高油藏动态管理水平。
Objective To determine the local industrial oil flow standards suitable for the ultra-low permeability oilfields in northern Shaanxi and to improve the calculation accuracy of reserves of such oilfields. Methods Numerical simulation and analogy were used to determine the standard of industrial oil flow in this field. As a result, the industrial oil flow value calculated according to the national standard is obviously smaller and the error is larger. By using the decreasing production method and considering factors such as the market price of crude oil, the investment in oilfield development, the cost of oil and gas production and the profit of crude oil, new industrial oil products Flow standard, more suitable for the actual low permeability oil field in northern Shaanxi. Conclusion The new industrial oil flow standard can improve the calculation precision of reserves, facilitate the adjustment of oilfield development plans and improve the dynamic management level of oil reservoirs.
