摘要

为了准确预测产聚时间、产聚浓度等含聚采出液关键指标,提出了基于井间连通性的产聚浓度预测方法,通过与数值模拟软件计算结果的对比进行了验证,并进行了实例分析。在水驱井间连通性模型的基础上,考虑聚合物的黏度、浓度、吸附量和水相渗透率下降系数等关键参数,建立了聚合物驱生产动态预测模型。与传统数值模拟方法相比,该模型需要求解的压力方程组维数较低,且通过自动历史拟合反演井间传导率和连通体积,提高了计算速度和精度。采用1注4采均质油藏模型,通过与数值模拟软件计算结果的对比验证了模型的可靠性和准确性,并对主要模型参数进行了敏感性分析,发现随着注聚后水相渗透率下降系数、注聚浓度和注入孔隙体积倍数的增加以及注聚时机的提前,驱油效果变好。应用实例分析结果表明,建立的模型能有效预测不同开发方案的产聚浓度变化规律。图10参22

Abstract

To forecast some key parameters of produced liquid containing polymer, including the time of polymer output, polymer concentration, a polymer concentration prediction method based on interwell connectivity methodology was established, its prediction results were compared with those from numerical simulation software, and it has been used in a case study. On the basis of water flooding interwell connectivity model, a polymer flooding production performance prediction model considering the viscosity, concentration, adsorption and water-phase permeability reduction factor of polymer was built. Compared with the traditional numerical simulation, the pressure equations in this model have lower dimension, and it inverses the interwell conductivity and connected volume through automatic history matching, enhancing calculation speed and precision significantly. The calculation model was used to the history matching of a homogeous reservoir model with 1 injector and 4 producers, and the comparison of its results and the results from numerical simulation software shows the model is reliable and accurate. Moreover, sensitivity analysis of major model parameters reveals that the increase of water-phase permeability reduction factor, injected polymer concentration and pore volume injected and early polymer injection time can improve oil recovery. The real reservoir application shows the model can predict the change of produced polymer concentration of different development schemes accurately.
