摘　　要：目前两流量试并解释方法单一，解释软件缺少历史拟合检验功能。消城油田有杆泵抽油井两流量试并资料影响因素多，导致半对数曲线于变万化，不易准确确定其直线段状况，由此探讨了用近期压力验证所选直线段的四种方法，即①利用本并近期实测油层平均压力pi值验证；②利用本并两流量试并资料估测的值验证；③利用同一开发层系（层位）近期统计值验证；④利用相邻油水井近期统计值验证。通过应用压力验证方法，提高了解释质量，确保了解释成果的可靠性。At present, interpretation method for dual rate well testing is unitary, interpritateon software is short of verification function for history match. From the information of Pachen Oilfield, there are lots of factors affecting dual rate well testing data of pumping wells equipped with rod pumps, resulting in various shapes of semi-log plot, straight line is not easy to be accurately fixed. This paper approaches four metheds to verify the straight line fixed by use of recent pressure in formation, these methods are ① Verification with recent average formationpressure pj actually measured in the same well;②Verification with value evaluated from same dual rate well testing data; ③Verification with recent statistical value from same layer series of development ; ④Verification with recent statistical value from neighbouring oil wells or water injection wells. Application of these pressure verification methods has increased interpretation level and has ensured reliability of interpretation results.
