Abstract
本文从井筒流体力学出发，利用平均温度和平均气体偏差系数方法计算了大牛地气田盒3气藏6口井70组井底流压数据，通过分析认为可以使用该方法计算盒3气藏单采井的井底流压。进一步通过回归分析的方法构建了盒3气藏单采井的流压关于套压的线性关系式，确定了现场使用套压计算无阻流量的新方法。在求取无阻流量的过程中，该方法具有测试数据少，工序简单的特点。 From the wellbore fluid mechanics, the 70 wellbore pressures of 6 wells in the H3 gas reservoir in Daniudi gas field were calculated by using the average temperature and the average gas deviation factor method in this paper. The results showed that this method can be used for calculating of the wellbore pressure, and then the linear relation between the casing pressure and the wellbore pressure was constructed by regression analysis method. This method has the advantages of simpler procedure and fewer test data in the process of calculating the open flow.
