摘要
使用二项式产能解释模型、指数式气井产能解释模型、一般单点法气井产能解释模型、指数式单点法气井产能解释模型和二次单点法气井产能解释模型,分别对涩北气田气井产能试井资料进行解释与对比,筛选了适合于涩北气田的气井产能试井解释模型。利用防砂气井措施前后的产能试井资料拟合得到IPR曲线,评价了涩北气田80井次的防砂措施改善井底流动条件的效果,其评价结果与气井生产动态分析结果比较一致,具有较好的可信度,为涩北疏松砂岩气藏防砂效果评价找到了一种新的手段。
By using binomial,exponential,general single-point,exponential single-point and secondary single-point gas well productivity interpretation models respectively,interpretation and comparison of gas well productivity's well test data in the Sebei gas field have been done to screen out the suitable gas well productivity well test interpretation model for the Sebei gas field.The evaluation of sand control measures for improving bottom-hole flowing conditions of 80 wells in the Sebei gas field has been done by using the IPR curve that is obtained by productivity well test data simulation of sand-control gas wells.The evaluation results,in agreement with those of gas well production performance analysis,have higher reliability,thus providing a new approach for the evaluation of sand control effect in the loose sandstone gas reservoirs in the Sebei gas field.
