塔河油田是典型的缝洞型碳酸盐岩油藏，油藏非均质性强且底水活跃。由于前期开采强度较大，水淹、水锥、水窜现象日益严重，关井、缩嘴、注水压锥方式已不同程度失效，堵水逐步成为油田稳油控水的主要方式。作为堵水的第一步，选井选层直接关系到油井堵水的效果，是堵水获得成功的前提。结合塔河油田堵水的具体实践，从地质、开发、工程工艺3方面总结了堵水选井选层的主要影响因素，并对五项基础综合分析法、权重分析法、神经网络法选井作了一定的对比分析，进而提出了系统选井法的理论。所总结的因素和方法对塔河碳酸盐岩油藏的堵水工艺发展有重要的指导作用，适用于同类油藏。

Tahe Oilfield is typical fractured-vuggy carbonate reservoir,which is seriously inhomogeneous and has active bottom water. Because of the high development rate early,water flooding,water coning and water channeling gradually worsen. Well shutin,narrow nozzle and water injection for coning control are failure at some degree,so water plugging is becoming the main method for stabilizing oil production and controlling water cut. As the first step,choosing wells and layers is directly relative to effect of water plugging,therefore,it′s precondition of success when water plugging. This paper summarizes some significant factors from aspects of geology,development,engineering and technology when choosing wells and layers for water plugging,combing with specific practice of water plugging in Tahe Oilfield. Then we make a comparison among for comprehensive analysis using five kind of basic information,weight analysis and artificial neural network,and finally put forward the theory of systematical well choosing. These factors and means have an important meaning for water plugging in carbonate reservoir of Tahe Oilfield,which is also suitable for the similar reservoir.
