摘要
依据"一点法"气井产能方程,分析了影响气井无阻流量的因素及其程度;结合陕北山西组6口井的实测气量,确定了目标区块对应层位的产能系数(平均0.617,与传统的0.254有较大差异),建立了快速确定目标区块气井无阻流量的计算公式,对该区的产能建设和滚动开发具有较强的实际指导意义。
Influence factors and its extent of AOF for gas wells are analyzed based on one-point method of productivity equation.Combing with the actual tested gas production from 6 gas wells at Shanxi formation in Shanbei oilfield,deliverability coefficients are calculated on spots(average value is 0.617 which is more difference from the traditional value 0.2541),and the formula to calculate rapidly AOF of object wells is obtained,which has an important practical guiding significance for producing energy construction and rolling development in gas fields.
