低渗透油田中注靖边气田天然气开发的数值模拟

Numerical Simulation of the Development of Low Permeability Reservoir by Injecting Natural Gas from Jingbian Gas Field

针对低渗透油田开发水平低的问题，结合安塞低渗透油田靠近靖边大气田的条件，应用三维三相全组份模型，探索研究了注天然气或／和溶解气开发低渗透油田的可行性，数值模拟结果表明，注气开发比自然能量开发单井产量成倍提高，提高低渗透油田开发水平的关键也在于采取单并增产措施，提高单井产量．

n view of the situation that the development level of low permeability reservoir is rather low andthe fact that the low permeability reservoir of Ausal is near Jingbian Natural Gas Field,a full compositional simulation model of three dimensions and three phases was used to study the feasibility of developing low permeability reservoir by injecting natural gas or/and solution gas. The results show that compared with the development by natural energy,the production rate of single well in gas injection development has doubled and redoubled.The paper points out that the key to raising the development level of low permeability reservoir is toincrease the production rate'of single well by adopting production increase measures for single wells
