- 摘要:
确定低渗油藏储层吸水能力,对注水开发方案制定、开发效果预测和注水设施配置有重要参考价值。通过利用油藏探井资料获得的油藏平均毛管压力曲线,确定储层贡献于渗流的毛管半径及孔隙体积,再由泊谡叶方程求出理想毛管束储层日吸水能力。在此基础上引入理想模型校正系数f1和流体物性校正系数f2,最终得出低渗储层吸水能力计算方法。采用此方法预测渤海BZ油田低渗储层吸水能力，预测结果与实际情况基本一致,表明研究得出的低渗储层吸水能力计算方法较准确具有一定实际应用价值。
Determination of water absorption capability in low permeability reservoir has the important reference value for flooding-development, speculating the water-flood effect and configuring corresponding construction facilities.This paper uses data of exploratory well to get the average capillary pressure curve of reservoir, and then determines the capillary radius and pore volume of reservoir rock contributing to the seepage, and calculates the daily water absorption capability of ideal capillary bundle modelaccording toPoiseuille-equation.On that basis, the model and fluid correction factorsf1andf2have been introduced to calculate water absorption capability eventually.Analysis on comparison between the actual data and the calculated results are basically the same, which indicates that the method has certain reference value in oil-field development.
