A Study on the elimination of barrier to bottom water coning

A study is made on the mechanism of bottom water coning in well, and the shape of the bottom water coning through the barrier. Based on Coats bottom water flow model, calculate the botom water influx when it coning through the barrier, and study the function of the location of barrier size and height to bottom water coning. The results indicated that the barrier on the oil/water contact has the big effect on elimination of bottom water coning, and can increase exploit effect; the bigger the barrier is ,the more decrease the bottomwater influx,and the longer its valid time. On the other hand, the strata heterogeneity and exploration speed have the effect on the barrier working on bottom water coning. In addition, extract speed and penetrate degree of reservoir with barrier may rise to some extent.
