直井注水平井采低渗薄层调驱技术研究与应用
Research and application of profile control with vertical injector + horizontal producer in low permeability thin reservoir
摘要
Abstract
Block Ci631 is a complex small faulted block with low permeability, thin formations and low natural energy. The water cut in corresponding horizontal producer increases rapidly after water injection into vertical well. Numerical simulation was conducted to study residual oil distribution and water flooding behavior in Block Ci631. Tracer data and microseismic test data of waterflood front were analyzed. In - depth profile control was conducted in vertical injectors with delayed crosslinked weak gel injected at small displacement and large radius. After profile control treatment, the direction of water flooding has changed and production has increased remarkably.关键词
