摘　　要：高浅1井是临清东部的第一口浅层亮点气藏,它的成功对增加临清地区勘探领域具有显著的意义。通过对压力、温度梯度测试资料的分析,确定了该井井筒内的CO2相态分布特征;通过对修正等时试井、压力恢复试井等测试资料的分析,确定了无阻流量、有效渗透率、表皮系数等参数;并充分运用试井解释成果,确定了该井区的储层非均质性及该井的污染情况。该井的测试评价,为正确认识该井地层特征和建立合理的工作制度提供了可靠的依据,并为该区CO2气资源的开发利用提供了技术支持。Well Gaoqian 1 is the first bright spot gas reservoir with shallow layer in eastern Linqing Area. The success of its exploitation has great significance to extend the exploration in Linqing Area. By analyzing the test data of pressure and temperature gradient, the phase distribution of carbon dioxide in the wellbore is determined. By analyzing the data of modified isochronal test and buildup test, the parameters as absolute open flow potential, effective permeability and skin factor are obtained. The reservoir heterogeneity and formation damage are also evaluated by using the result of well test interpretation. The test evaluation for this well can provide reliable basis for knowing the reservoir characteristics and establishing production system. It also offers technological support for the carbon dioxide resources exploitation and utilization in this area.
