Analysis of Inter-Well Correlation in Carbonate Reservoir

Article Preview

Abstract:

The evaluation of inter-well correlation is an important basis which can instruct engineers to analyze reservoir water-flooding effect, propose the adjustment suggestion. To solve the difficulties of water-flooding evaluation of carbonate reservoir, a new method is proposed based on inter-well connectivity and unascertained math. Firstly, an independent evaluation index system is established before calculating the comprehensive evaluation index weights by the analytic hierarchy process and similarity weight method. Then the Uncertainty measure model is established to evaluate water-flooding effect of well group. This method has been applied in the X oilfield, and good results are gained. The results show that different adjustments should be taken to improve water-flooding effects in different units.
