Water Invasion Prediction Method for Edge–Bottom Water Reservoirs: A Case Study in an Oilfield in Xinjiang, China

Clarifying the water invasion rule of edge and bottom reservoirs can adjust reservoir development mode improve recovery factor in a timely manner. Influenced by size body, energy intensity seepage capacity, change model influx basically belongs to exponential growth GM (1,1) or self-constraint logistic model. The above two models are used predict analyze inflow reservoirs, respectively, it is found that with sufficient more consistent prediction results model, but has large error compared insufficient research shows strength be determined analyzing predicting influx. If we focus on influx, improved formed Newton parabola interpolation polynomial optimize its background value, which further accuracy reduce reservoirs. method this paper certain reference significance for studying
