摘要
苏里格气田属于典型的低渗透低丰度砂岩气田,气井产量递减速度快,开发难度大。及时了解气田所处的生产阶段,准确预测气田后期产量变化和可采储量是调整气田开发模式,合理配产,有效提高开发效果的有效手段。通过对苏里格气田苏25区块气井产量递减规律研究,确定了该区块的产量递减规律,利用产量递减资料,计算单井的裂缝半长,弥补了试井资料的缺陷,并对苏25区块生产周期内的月产量、可采储量以及采出程度进行了预测,预测结果与实际相符,可用于生产实际。
Sulige gas field is a typical low abundance of low permeability sandstone gas field,gas production declines fast and development is difficult. Understanding production stage in time to accurately predict changes in post-production and recoverable gas reserves is a effective manner to adjust gas field development model,mach rational distribution of production,improve the development effect. Through study on decline law of Su 25 gas blocks in the Sulige gas field to determine the diminishing law in this block,and by use of production decline data,the crack half-length in single well is calculated to make up for the shortcomings of testing data,and to predict the monthly production,recoverable reserves and production degree of the Su 25 blocks. predicted results is corresponding to the actual,which can be used for actual production.
