Abstract:

The mathematical model of grey comprehensive evaluation is introduced. Grey correlation analysis method is used to confirm the importance degree of all the selected projects and the optimal decision is then obtained. The selecting of appropriate well for fracturing is the basic condition to obtain nice commercial efficiency. At present, it depends on the expert experience in oilfield to select fracturing well, which has certain blindness. The factors affecting the fracturing effect are mainly geologic factor, construction factor and other human factor, of which the relations are complex and nonlinear. The geologic factor is mainly considered and the analytical hierarchy process is applied to determine the weight of the factors. Grey correlation analysis method is used to analyze the correlation between the selected well and optimum well, and then optimize the appropriate wells for fracturing. This method is applied in Huangchang block in Jianghan Oilfield, and the result proves the effectiveness.

Key words: source of water body, characteristic of wate breakthough, stabilizing oil production and controlling water cut, Tahe Oilfield
