用生产井信息确定储层非均质性

储层非均质性是油气田地质和开发工程中经常需要解决的问题，因为它在某种程度上决定了油气田内各井的油气产能。根据美国一些开发多年的油气田产量等生产数据（如累积产量、年度产量和月度产量等），利用数理统计方法结合地质分析提出了月度产量变异系数、年度产量变异系数和累积产量变异系数等特征参数，这些参数能有效地反映储层层内和平面非均质特征，对于高含水期的老油气田油藏地质模型研究很有帮助。

ESTIMATION OF RESERVOIR HETEROGENEITY WITH PRODUCTION DATA

Production potential of each well in an oilfield or gasfield is mainly controlled by the reservoir heterogeneity. This paper introduces a series of parameters, including cumulative production, annual yield and monthly production, to estimate the reservoir heterogeneity of oil and/or gas fields those have been developed for a long time. These parameters effectively express inner layer and plane heterogeneity of the reservoirs, which has much help for research of geologic model for the reservoirs.
