生产分析可预测气井的产量,获得在地面波结点的生产压力和平均气层压力。生产分析还能研究气层渗透率、完井与生产管线的细节。图1是用图解法表示生产分析用于气井的两个著名关系曲线。气流动态(IP)曲线表示井的流动压力(P_wf)随天然气产量(Q)的变化。IP曲线是根据气层的平均压力、气层的平均渗透率和完井(包括射孔)细节用数学方法制作的。
Production analysis predicts gas well production and obtains production pressure and mean gas pressure at ground-wave nodes. Production analysis can also study gas permeability, completion and production pipeline details. Figure 1 is a diagrammatic representation of two well-known relationship curves for gas wells in production analysis. The flow dynamics (IP) curve represents the change in well flow pressure (P_wf) as a function of gas production (Q). IP curves are mathematically prepared based on average gas pressure, average gas permeability, and completion (including perforation) details.
