摘要：
油井或气井出现载水现象后,不断上升的水柱不仅会降低储层与井筒间的压差影响油气产出,而且改变了井筒中流体介质分布和速度分布,造成生产动态监测方面的困难。提出了依据流量计、密度计、持水率计等曲线判断油井或气井是否载水的新方法,基于对不同井段的流型进行了分析,提出了相应产出剖面测井仪器系列及其测井资料处理解释模型。

Abstract: Continuously uplifted water column not only reduces the pressure difference between reservoir bed and well bore,and influences well's production,but also changes the distribution of fluid and its velocity,and lead to it difficulty to inspect well's production after oil or gas well carries water.This paper puts forward a new method to judge if oil or gas is carrying water basing well logging curves such as flow rate,density,and holdup,and puts forward corresponding well logging instrument series and interpretation model to deal with production profile data by analyzing flow regime of different segment in well bore.
Keywords: Production logging; Inperpretation method; Carrying water phenomenon
