The Well Pattern Optimization of Chemical Combination Flooding in Mid-low Permeability Reservoir
摘要
Abstract
Take Block S, a mid-low permeability sandstone reservoir, for example, the paper designs well pattern of chemical flooding and enhances oil recovery factor at the stage of ultra-high water-cut. Based on the adjustment history of well pattern, such three different well patterns as inverted 5-spot and inverted 13-spot combination well pattern, little 5-spot well pattern and tilted-line well pattern, numerical simulation technology is used to predict the performance of chemical flooding. The results show that tilted-line well pattern has strong feasibility for early result and long sustainable period and can enhance oil recovery of 12.96%; the combination well pattern is second to it; and little 5-spot well has less feasibility. Considering chemical injectors and facility investment, the optimized well pattern of the target area should be tilted-line well.关键词
