摘要: 根据岩心压汞资料,获得砾岩储集层渗透率与孔隙中值半径的关系,结合滤膜实验建立的不同聚合物相对分子质量与可通过孔隙尺寸的关系,建立了砾岩油藏驱油聚合物相对分子质量的选择方法。利用此方法研究后得出:七东1区克下组油藏驱油适选聚合物相对分子质量为2500×104的聚合物,该方法对其他砾岩油藏驱油聚合物相对分子质量的选择具有指导意义。

Abstract: Based on the data of core analysis, the relationship between the permeability and median radius of porosity in the conglomerate reservoir in Karamay field is established. Integrated with the relations of relative molecular mass of several polymers with suitable pore sizes given by filter membrane experiment, the method for selection of relative molecular mass of plymers by polymer flooding process in conglomerate is proposed. It is shown from this study that the polymer flooding of T1k1 of East District 7 (1) in conglomerate reservoir in Karamay field should be performed by the relative molecular mass of 2 500×104 of polymer. This method could be as a guide for the polymer choice of other conglomerate reservoirs.

Key words: conglomerate reservoir, polymer, relative molecular mass, method
