摘　　要：哈萨克斯坦哈德油田试井工作起步较晚,资料采集和解释结果与实际井况偏离较大。在原始试井资料采集方面,通过分析比较近年来该油田试井资料,提出了个性化设计单井关井时间、缩短关井与开井时采样间隔的改进意见。选取解释基础参数时,考虑了含水对黏度和体积系数的影响。确定解释模型时,需要综合考虑各种影响因素。与原方法相比,改进后的方法提高了解释曲线与实测数据的拟合度,试井解释结果更加合理,能为油田开发方案调整提供更可靠的依据。Pressure tests started relatively late in Kazgermunai oilfield of Kazakhstan,and data acquisition and data interpretation results deviated greatly from the actual well conditions.In the aspect of raw test data acquisition,suggestions for improving unique designs of shut-in period for individual test well and shortening sampling intervals at the beginning and at the end of shut-in are proposed through analyzing and comparing test data in recent years in the oilfields.The influence of water-cut on viscosity and volume coefficient was considered when selecting the basic parameters for interpretation.To determine the interpretation model,comprehensive factors are considered.Compared with the interpretation results of the original method,fitting degree of the new method has been improved.Well test interpretation results are more reasonable,which can provide more reliable basis for optimization of oilfield development plan.
