摘要: 水平井产出剖面测井是评价非常规气藏开发生产动态的关键技术手段,准确定量各生产层气水产量是指导气藏开发方案优化调整的关键基础。采用不同于现有MAPS和FSI的阵列式光电扫描测井仪(FAST)监测资料为切入点开展研究,通过分析阵列涡轮流量、阵列多普勒流量、阵列电导持水率和阵列光纤持气率响应,反演井筒气水介质分布,针对性建立考虑阵列仪器旋转的径向投影中点切分面积权系数计算新方法,实现水平井平均流体速度、平均持气率和持水率的高精度定量计算。以四川盆地页岩气水平压裂井QH1井两种工作制度下的实测资料开展应用研究,综合对比表明,建立的方法模型计算得到全流量层气水分相流量与井口计量误差小于6.5%,单层气水产量与储层特征匹配较好,较好满足了非常规气藏水平井生产动态评价及压裂效果评价需求。

Abstract: Production profile logging in horizontal wells is a key technique means to evaluate the development and production performance for unconventional gas reservoirs, and accurate quantification of gas and water production in each production layer is the key basis for guiding the optimization and adjustment of gas reservoir development. A new logging system, flow array sensing tool(FAST), which is different from the existing production logging tools such as MAPS and FSI, was introduced for research. By analyzing the response characteristics of array turbine flow, ultrasonic flow, array conductivity and optical fiber holdup curves, a comprehensive quantitative calculation method for fluid velocity based on array turbine flow rate and ultrasonic flow rate and gas and water holdup based on array conductivity and optical fiber holdup data were established. Case study has been carried out based on the measured curves under 2 working systems for fracturing shale gas horizontal Well QH1 from Sichuan basin. Comprehensive comparison shows that the gas and water production of each production layer calculated based on the proposed method is more matched with the actual reservoir characteristics, and the relative errors between the gas and water production of the full flow layer and wellhead is less than 6.5%, which shows that this new method can better meet the requirements for production performance evaluation and fracturing effect evaluation of horizontal wells in unconventional gas reservoirs.

Key words: horizontal well, gas and water phase, flow array sensing tool, production profile, production performance
