考虑微观孔喉结构的相对渗透率计算方法
A new method to calculate relative permeability considering the effect of pore-throat distribution
摘要
Abstract
As conventional oil and gas resources are exhausted ,ultra‐low permeability reser‐voirs are the basis of the energy in the country .Relative permeability curves are the key fac‐tor to development .Micro pore and throat structure has a significant effect on relative perme‐ability curves .However ,existing methods to calculate permeability curves cannot take micro pore and throat structure into consideration .T herefore in this paper a new method consider‐ing the effect of boundary ,Jamin and micro pore‐throat distribution is established by modi‐fied Brooks‐Corey model .It is found that compared to ultra‐low permeability reservoir of Daqing Field ,Daqing Field has a wider distribution of pore and throat .As a result ,the region of two phase of Changqing Field is wider .Oil relative permeability of Changqing Field is lar‐ger .Relative permeability curve of Changqing Field changes more seriously when water cut is high .That is the theoretical basis to the successful development for Changqing and Daqing Field .关键词
