Abstract: Weather succeed or not in oil well water shutoff is affected by many facts. In order to enhance the efficiency of the water shutoff job, the model steps of solution method were presented in this paper. It includes the selection of water shutoff well, the identification of water production mechanism, the optimum of design, the technology of construct and the filter of direction for producing chemicals. The important of temperature field simulate in the filter of direction for producing chemicals was pointed out. Using this suit of method, it not only can improve the efficiency of water shutoff, but also can help the runner and the decision-making to analyses the effects.
