摘要
油藏物质基础、完井方式、井眼轨迹、出水方式及位置等是水平井控水成功与否的重要影响因素。由于油层产出剖面复杂,前期通过油藏数值模拟及生产动态分析进行出水方式及位置判断存在不可避免的认识不足,甚至失误。以Wen8-3-A2h井为例,在控水作业实施前,通过油藏数值模拟、生产动态分析进行及水平井生产测井,确定油井的产出剖面。实施后,综合分析整个作业实施前后过程中的要素及控水效果评价,建立一套工作流程和方法,以对水平井控水工艺方案提供指导、借鉴。
Reservoir foundation, well completion method, well track, Water way and position are the most impor- tant elements of horizontal well water control success. Due to the complex production section, there is inevitably in- sufficient understanding or even the failure on the early adoption of reservoir numerical simulation and dynamic analysis in water way and position estimation. For example of Wen8-3-A2h well, in the control of water activity be- fore implementation, through resepcoir numerical simulation and dynamic analysis as well as horizontal well produc- tion logging is determined the oil well production profile. After action, a comprehensive analysis of the whole opera- tion before and after the implementation of the essential elements and effect, establish a work process and method to provide guidance, draw lessons from the horizontal well water control technology.
