摘要
通过实测苏里格气田岩样在不同覆压下的渗透率,讨论了低渗岩样在覆压实验中的变形特征,在实验及理论研究的基础上,推导出了考虑岩石应力敏感的气井产能公式,结合苏里格气田储层的实际情况,评价了岩石应力敏感对气井产能的影响。
The permeability of rock samples from Sulige gasfield was tested at various overburden pressure.The deformation characteristics of low-permeability rock samples in overburden pressure experiments were discussed.Based on experimental and theoretical studies,the well deliverability equation in which rock stress sensitivity had been taken into consideration was established.Combined with the actual reservoirs in Sulige gasfield,the effect of rock stress sensitivity on well deliverability has been evaluated.
