摘要
气井的地层压力梯度随着井深的变化而变化,使用气井流动压力梯度折算的目的层流压与目的地层真实流动压力存在一定的偏差,针对此种情况选取同一区块两口井分别采用气井流压梯度计算和实测井底流压计算的无阻流量进行对比,分析此两种方法计算的无阻流量存在的差异,经现场对比应用结果表明,使用流动压力梯度折算的井底流动压力计算的无阻流量较实测目的层井底流动压力计算的无阻流量偏大。
Gas well formation pressure gradient change with well depth increase.It is deviation that flow pressure gradient of gas well reduced target interval flow pressure and real target interval flow pressure.In such cases that we select two wells in the same block to contrast open-flow capacity that flow pressure gradient of gas well calculation and measured well bottom flow pressure,and analysis differences of the two methods calculate open-flow capacity exist.The field application shows that flow pressure gradient of gas well reduced target interval flow pressure calculation open-flow capacity more than real target interval flow pressure.
