摘要
论述了气井生产优化分析方法,并建立了了下渗流、垂直管流和地面水平管流的数学模型,用该数学模型可以给出气井生产的流入及流出动态曲线,根据这组曲线可以确定气井生产的优化方案,即优化的参数组合。对所建立的数学模型进行了程序设计,结合实际资料进行了计算,并得出气井生产的最佳油管尺寸,油咀尺寸,射孔密度,流量及井底流压等参数。
The paper expounds the method for optimization analysis in gas well, and sets up a mathematical model of fluid flow through porous medium, vertical pipe and horizontal pipe. This mathematical model may give inflow-outflow performance relationship curves of gas well production. On the basis of the curve, the optimization plan of gas well production may be ascertained, namely a set of optimization parameters. The calculation is made by use of program and oilfield data, and optimization parameters are given of tubing size, choke size, perforation density flow rate and flowing pressure.
