| 摘 要： | 低渗透油藏的压力恢复曲线,不能用Horner外推压力求取地层压力。基于Horner方程的等轴双曲线形式,提出了应用压力早期恢复资料确定低渗地层压力的新方法。通过油井实际资料计算验证,用该方法计算的地层压力准确可靠,较好地解决了低渗透油藏求地层压力的问题。

| Abstract: | For the pressure recovery curve to the low permeability reservoir,formation pressure can not be obtained by using Horner to strike extrapolation pressure.Based on the axis hyperbolic form of Horner equation,a new approach for the application of pressure confirmed by early low permeability reservoir pressure data is identified,by calculation and validation of actual data,the result of formation pressureis accurate and reliable.The problems of low permeability reservoir formation pressure are solved better. |
