试井解释方法在上古盒_8气藏中的应用

Application of Well Test Interpretation Method in Ancient Box 8 Gas Reservoir

随着气田的深入开发,试井作为一项获取气井储层特征的测试项目越来越发挥出它的重要性。为了更好地对上古盒8气藏进行试井解释分析,采用图形分类、模型选择、参数拟合、地质综合分析、试井动态预测等方法对上古盒8气藏进行试井解释,总结出一套适用于上古砂岩盒8气藏的解释方法,获得地层有效渗透率、表明井底受污染情况的表皮系数、不渗透边界的大致形状及边界的距离等对气田开发有重要意义的参数,为气田的进一步开发提供第一手资料。

With continuous gas field development,as a test item for obtaining gas well reservoir characteristics,well testing more and more shows its importance.In order to analyze better ancient box 8 gas reservoir well test interpretation,used are such methods as pattern classification,model selection,parameter fitting,geological analysis and well testing dynamic prediction and summarized is a set of interpretation methods suitable for the ancient box 8 gas reservoir,obtained are very significant parameters,such as effective permeability of the strata,skin factors indicating well bottom pollution,approximate shape of impermeable boundary and boundary distance,which can provide the first-hand information for further development of the gas field.
