摘要
油层的非均质性对油藏开采效果影响甚大。传统方法研究非均质分布规律对于子样分布为双峰的情形局限较大。提出了解决双峰型密度函数的解析方法，根据统计资料研究油层非均质分布规律。子样分布为双峰时， 利用叠加方法确定分布规律， 从而扩大了根据子样寻找理论分布的范围， 并提高了精度。应用该法编制的软件， 使油层非均质双峰分布规律的确定更加方便和精确， 满足了油田现场的需要。
Heterogeneity of a reservoir bed has a rather great effect on its exploitation. Classic method for the study of the distribution pattern of reservoir heterogeneity has rather big limitation in the case of double peak distribution. An analytical method for solving the double peak type density distribution function is suggested in this paper, to study the distribution pattern of the heterogeneity of a reservoir bed. The means of adding method used to determine the double peak distribution was discussed and the range of theoretical distribution determined from sample date was expanded and the accuracy was increased. By an application of the software using this method, it is more easy and more accurate to determine the double peak distribution pattern of reservoir heterogeneity, and the requirement of oil field is thus satisfied.
