摘　　要：针对热采水平井出水影响因素复杂,并严重影响其开采效果的问题,采用数值模拟方法研究目标A油田热采水平井含水上升的影响因素,包括水平井的水平段长度、日产液量等,分析出水机理,并利用正交试验分析法进行多因素影响次序研究;基于A油田高含水水平井出水原因分析,提出生产动态与测井资料综合分析找水法,并制定判定标准。应用目标A油田两口典型高含水热采水平井ABA98、ABA03的生产动态、压力测试、井口温度以及产出水矿化度等资料,综合分析两口井的产出水来源,判断各井的出水原因,并结合测井资料分析出水位置。In view of the complex factors affecting the water breakthrough of thermal horizontal wells and seriously affecting its production effect,numerical simulation methods are used to study the factors affecting the increase in water cut of thermal horizontal wells in the A oilfield,including the horizontal section length,daily liquid production,etc.Then,the water breakthrough mechanism of horizontal wells CSS is analyzed,and multi-factor influence sequence analysis is carried out by using orthogonal test method.On basis of the analysis of water breakthrough reasons of the high water cut horizontal wells in the A oilfield,the water finding method of comprehensive analysis of production dynamics and logging data is proposed,and the judgment criteria is set.Using the production data,pressure test,wellhead temperature and salinity of produced water from two typical high water cut horizontal wells ABA98 and ABA03 in target A oilfield,the water breakthrough reason are judged,and the source of produced water and the water breakthrough section combined with the logging data are analyzed comprehensively.
