气井井底流压计算方法优选

Optimal for Calculating Method about Bottom-Hole Pressure of Gas Well

气井井底流压是动态分析的重要参数,目前计算井底流压的方法较多,但每种方法适用的条件又不相同。针对这种情况,介绍了求取井底流压的三种方法:静气柱计算法、单相流计算法和气液两相流计算法,并对这三种方法的适用条件及优缺点进行了分析。

Bottom-hole flowing pressure of the gas well is the important parameter for dynamic analysis.Methods of calculating bottom-hole pressure are more currently.But the applicable condition of each method is different.In view of this situation,three ways are introduced to acquire the bottom-hole pressure,that are static column approach,single-phase flow calculations and gas-liquid two-phase flow calculations,and the applicable conditions of these three methods and the advantages and disadvantages are analyzed.
