单井产能预测对油田的进一步开发有着重要的意义,它是为油田提供有利开发方案的关键环节之一。单井产能预测方法多样,本文针对A油田低孔、低渗的储层特点,从定性和定量两个角度出发,充分利用测井资料信息,提取与产能有关的多个地质参数,其中主要考虑四个关键参数:孔隙度Φ、渗透率K、有效厚度H、含油饱和度So,将其分别与目的层的产量进行相关分析,得出储层产量的主要测井控制因素。利用测井资料对储层进行合理分类,最后分别应用产能系数法、有效厚度与含油饱和度乘积法计算产量,从而对储层进行产能预测。
Single-well productivity forecasting is of great significance to the further development of oilfields. It is one of the key steps in providing favorable development plans for oilfields. According to the characteristics of low-porosity and low-permeability reservoirs in A Oilfield, this paper makes full use of logging data and qualitatively and quantitatively to extract multiple geological parameters related to productivity, of which the main considerations The four key parameters: porosity Φ, permeability K, effective thickness H, oil saturation So, and their correlation with the yield of the target layer respectively. The main logging control factors are obtained. The log data are used to classify the reservoirs reasonably. Finally, the production capacity is predicted by applying the productivity coefficient method and the product of effective thickness and oil saturation, respectively.
