Productivity Log Forecasting Method for Post-frac Reservoir withLow Porosity and Low Permeability
摘要
Abstract
Post-frac productivity forecasting in Chaoyanggou oilfield with low porosity and low permeability is made by means of researches on relative factors. The major factors which influence the post-frac productivity include: formation effective permeability, effective thickness, downhole fluid pressure, eta Determined is the productivity level standard, and given are 2 prediction methods; equation method and neural network method Built is the stable state flow equation method of infinite flow conductivity vertical fracture, and worked out is computing method for each parameter. Equation method is used to forecast the post-frac productivity in 11 wells, and productivity grade coincidence rate of single layer is up to 73%. When using neural network method to do training and prediction in 13 wells, the productivity grade coincidence rate reaches 100%.关键词
