- 摘要:
- 在油田开发动态分析、配产和产量规划中,常用递减率来分析预测油田的开发变化规律和未来趋势。为了快速、准确地进行油田产量预测,利用递减理论,推导了日、月、年综合递减率之间的相互关系；依据等比数列产量公式,提出折算生产天数概念。通过大量的计算、拟合,建立了递减率、月份与折算生产天数参数对照表,提出了快速、准确预测油田采油区块产量的方法,为油田日常开发管理工作提供了方便。
In dynamic analysis, production distribution and production planning forecast of oil field development, declining rate is used to analyze and forecast the changing regularity and the trend of oil field through development. To predict output fast and accurately, the interrelationship between daily, monthly and yearly comprehensive declining rate was investigated. According to the geometric sequence formula, the concept of "commuted production days" was proposed. Through numerous calculations and matching, a comparison table including declining rate, month and commuted production days was established. With this table, output can be predicted fast and accurately, which facilitates daily development and management of oil field.
