靖边气田新增探明储量区块实测地层压力资料与气层中部海拔进行拟合回归相关性较好,其压力梯度与气田本部压力梯度值很接近。新增储量区块内无论是天然气组份,还是相对密度与靖边气田本部都有明显的一致性,表现了同一气藏的特征。通过气藏流体性质和试气结果的分析,按照气井不同产量分为Ⅰ类、Ⅱ类、Ⅲ类井分别进行评价。对比本次新增探明储量区块与已探明面积内投产井配产指标发现,二者不同类型气井井数比例一致,单井平均无阻流量及平均配产产量也接近。
The correlation between the measured formation pressure data and the fitted regression of the central part of the gas layer in the newly discovered proven reserves in Jingbian Gas Field is good, and the pressure gradient is close to the pressure gradient in the gas field. No matter whether it is a natural gas component or a relative density in the newly added reserves, there is a clear consistency with the headquarters of the Jingbian Gas Field, which shows the characteristics of the same gas reservoir. According to the analysis of fluid properties and gas test results of gas reservoirs, the gas wells were divided into Ⅰ, Ⅱ and Ⅲ wells according to their different yields, respectively. Comparing the newly-added proved reserves block with the allocated production index of the proven production area, it is found that the proportions of the two types of gas well are the same, and the average unobstructed flow and the average production yield are also close to each other.
