摘要
提出一种利用单井生产历史数据(产气量、产水量、油套压)来计算有水气藏动态储量,同时求取单井产能与气藏水侵强度的新方法。该方法克服了传统方法对全气藏地层压力的依赖性。利用该方法计算了某生产井的动态储量,计算结果准确、可靠,表明计算方法快捷、实用。
A new method,to calculate dynamic reserves of gas reservoirs with water by production historical data of single well(like gas production,water production,and tubing and casing pressure),is proposed.Simultaneously,single-well productivity and water invasion strength are obtained.The method eliminates the dependence on formation pressure of whole reservoir existing in conventional methods.It has been also used to calculate dynamic reserves of production well,and the results are accurate and reliable.
